57 Prior to version 7.0, C-Kermit was always built with the most
58 conservative Kermit file-transfer protocol defaults on every platform:
59 no control-character prefixing, 94-byte packets, and a window size of
62 Starting in version 7.0, fast settings are the default. To override
63 these at compile time, include:
67 in the C compiler CFLAGS. Even with the fast defaults, C-Kermit
68 automatically drops down to whatever window and packet sizes requested
69 by the other Kermit, if these are smaller, when sending files (except
70 for control-character unprefixing, which is not negotiated, and which
71 is now set to CAUTIOUS rather than NONE at startup). C-Kermit's
72 settings prevail when it is receiving.

76 2. SERIAL COMMUNICATION SPEEDS
78 [ [38]Top ] [ [39]Contents ] [ [40]Next ] [ [41]Previous ]
80 As of 6 September 1997, a new simplified mechanism for obtaining the
81 list of legal serial interface speeds is in place:
83 * If the symbol TTSPDLIST is defined, the system-dependent routine
84 ttspdlist() is called at program initialization to obtain the list.
85 * This symbol should be defined only for C-Kermit implementations
86 that have implemented the ttspdlist() function, typically in the
87 ck?tio.c module. See [42]ckutio.c for an example.
88 * TTSPDLIST is automatically defined in [43]ckcdeb.h for UNIX. Add
89 the appropriate #ifdefs for other platforms when the corresponding
90 ttspdlist() functions are filled in.
91 * If TTSPDLIST is (or normally would be) defined, the old code
92 (described below) can still be selected by defining NOTTSPDLIST.
94 The ttspdlist() function can obtain the speeds in any way that works.
95 For example, based simply on #ifdef Bnnnn..#endif (in UNIX). Although
96 it might be better to actually check each speed against the currently
97 selected hardware interface before allowing it in the array, there is
98 usually no passive and/or reliable and safe way to do this, and so it's
99 better to let some speeds into the array that might not work, than it
100 is to erroneously exclude others. Speeds that don't work are caught
101 when the SET SPEED command is actually given.
103 Note that this scheme does not necessarily rule out split speed
104 operation, but effectively it does in C-Kermit as presently constituted
105 since there are no commands to set input and output speed separately
106 (except the special case "set speed 75/1200").
108 Note that some platforms, notably AIX 4.2 and 4.3, implement high
109 serial speeds transparently to the application, e.g. by mapping 50 bps
110 to 57600 bps, and so on.
112 That's the whole deal. When TTSPDLIST is not defined, the following
115 Speeds are defined in two places: the SET SPEED keyword list in the
116 command parser (as of this writing, in the [44]ckuus3.c source file),
117 and in the system- dependent communications i/o module, ck?tio.c,
118 functions ttsspd() (set speed) and ttgspd() (get speed). The following
119 speeds are assumed to be available in all versions:
121 0, 110, 300, 600, 1200, 2400, 4800, 9600
123 If one or more of these speeds is not supported by your system, you'll
124 need to change the source code (this has never happened so far). Other
125 speeds that are not common to all systems have Kermit-specific symbols:
128 Speed (bps) to enable to disable
131 75/1200 BPS_7512 NOB_7512
132 134.5 BPS_134 NOB_134
135 1800 BPS_1800 NOB_1800
136 3600 BPS_3600 NOB_3600
137 7200 BPS_7200 NOB_7200
138 14400 BPS_14K NOB_14K
139 19200 BPS_19K NOB_19K
140 28800 BPS_28K NOB_28K
141 38400 BPS_38K NOB_38K
142 57600 BPS_57K NOB_57K
143 76800 BPS_76K NOB_76K
144 115200 BPS_115K NOB_155K
145 230400 BPS_230K NOB_230K
146 460800 BPS_460K NOB_460K
147 921600 BPS_921K NOB_921K
149 The [45]ckcdeb.h header file contains default speed configurations for
150 the many systems that C-Kermit supports. You can override these
151 defaults by (a) editing ckcdeb.h, or (b) defining the appropriate
152 enabling and/or disabling symbols on the CC command line, for example:
154 -DBPS_14400 -DNOB_115200
156 or the "make" command line, e.g.:
158 make blah "KFLAGS=-DBPS_14400 -DNOB_115200"
160 Note: some speeds have no symbols defined for them, because they have
161 never been needed: 12.5bps, 45.5bps, 20000bps, etc. These can easily be
162 added if required (but they will work only if the OS supports them).
164 IMPORTANT: Adding one of these flags at compile time does not
165 necessarily mean that you will be able to use that speed. A particular
166 speed is usable only if your underlying operating system supports it.
167 In particular, it needs to be defined in the appropriate system header
168 file (e.g. in UNIX, cd to /usr/include and grep for B9600 in *.h and
169 sys/*.h to find the header file that contains the definitions for the
170 supported speeds), and supported by the serial device driver, and of
171 course by the physical device itself.
173 ALSO IMPORTANT: The list of available speeds is independent of how they
174 are set. The many UNIXes, for example, offer a wide variety of APIs
175 that are BSD-based, SYSV-based, POSIX-based, and purely made up. See
176 the ttsspd(), ttgspd(), and ttspdlist() routines in [46]ckutio.c for
179 The latest entries in this horserace are the tcgetspeed() and
180 ttsetspeed() routines found in UnixWare 7. Unlike other methods, they
181 accept the entire range of integers (longs really) as speed values,
182 rather than certain codes, and return an error if the number is not, in
183 fact, a legal speed for the device/driver in question. In this case,
184 there is no way to build a list of legal speeds at compile time, since
185 no Bnnnn symbols are defined (except for "depracated, legacy"
186 interfaces like ioctl()) and so the legal speed list must be enumerated
187 in the code -- see ttspdlist() in [47]ckutio.c.

191 3. FULLSCREEN FILE TRANSFER DISPLAY
193 [ [50]Top ] [ [51]Contents ] [ [52]Next ] [ [53]Previous ]
195 New to edit 180 is support for an MS-DOS-Kermit-like local-mode full
196 screen file transfer display, accomplished using the curses library, or
197 something equivalent (for example, the Screen Manager on DEC VMS). To
198 enable this feature, include the following in your CFLAGS:
202 and then change your build procedure (if necessary) to include the
203 necessary libraries. For example, in Unix these are usually "curses" or
204 "ncurses" (and more recenlty, "ncursesw" and "slang"), perhaps also
205 "termcap", "termlib", or "tinfo":
207 "LIBS= -lcurses -ltermcap"
208 "LIBS= -lcurses -ltermlib"
213 "man curses" for further information, and search through the Unix
214 [54]makefile for "CK_CURSES" to see many examples, and also see the
215 relevant sections of the [55]Unix C-Kermit Installation Instructions,
216 particularly Sections [56]4 and [57]9.2.
218 There might still be a complication. Some implementations of curses
219 reserve the right to alter the buffering on the output file without
220 restoring it afterwards, which can leave Kermit's command processing in
221 a mess when the prompt comes back after a fullscreen file transfer
222 display. The typical symptom is that characters you type at the prompt
223 after a local-mode file transfer (i.e. after seeing the curses
224 file-transfer display) do not echo until you press the Return (Enter)
225 key. If this happens to you, try adding
229 to your makefile target (see comments in screenc() in [58]ckuusx.c for
232 If that doesn't fix the problem, then use a bigger hammer and replace
237 which tells Kermit to force stdout to be unbuffered so CBREAK mode can
240 In SCO Xenix and SCO UNIX, there are two separate curses libraries, one
241 based on termcap and the other based on terminfo. The default library,
242 usually terminfo, is established when the development system is
243 installed. To manually select terminfo (at compile time):
245 compile -DM_TERMINFO and link -ltinfo
247 and to manually select termcap:
249 compile -DM_TERMCAP and link -ltcap -ltermlib
251 <curses.h> looks at M_TERMINFO and M_TERMCAP to decide which header
252 files to use. /usr/lib/libcurses.a is a link to either libtinfo.a or
253 libtcap.a. The C-Kermit compilation options must agree with the version
254 of the curses library that is actually installed.
256 NOTE: If you are doing an ANSI-C compilation and you get compile time
257 warnings like the following:
259 Warning: function not declared in ckuusx.c: wmove, printw, wclrtoeol,
260 wclear, wrefresh, endwin, etc...
262 it means that your <curses.h> file does not contain prototypes for
263 these functions. The warnings should be harmless.
265 New to edit 190 is the ability to refresh a messed-up full-screen
266 display, e.g. after receiving a broadcast message. This depends on the
267 curses package including the wrefresh() and clearok() functions and the
268 curscr variable. If your version has these, or has code to simulate
273 The curses and termcap libraries add considerable size to the program
274 image (e.g. about 20K on a SUN-4, 40K on a 386). On some small systems,
275 such as the AT&T 6300 PLUS, curses can push Kermit over the edge...
276 even though it compiles, loads, and runs correctly, its increased size
277 apparently makes it swap constantly, slowing it down to a crawl, even
278 when the curses display is not in use. Some new makefile targets have
279 been added to take care of this (e.g. sys3upcshcc), but similar tricks
280 might be necessary in other cases too.
282 On the curses file-transfer display, just below the "thermometer", is a
283 running display of the transfer rate, as a flat quotient of file
284 characters per elapsed seconds so far. You can change this to an
285 average that gives greater weight to recent history (0.25 *
286 instantaneous cps + 0.75 * historical cps) by adding -DCPS_WEIGHTED to
287 your CFLAGS (sorry folks, this one is not worth a SET command). You can
288 choose a second type of weighted average in which the weighting smooths
289 out progressively as the transfer progresses by adding -DCPS_VINCE to
292 An alternative to curses is also available at compile time, but should
293 be selected if your version of Kermit is to be run in local mode only
294 in an ANSI terminal environment, for example on a desktop workstation
295 that has an ANSI console driver. To select this option in place of
296 curses, define the symbol MYCURSES:
300 instead of CK_CURSES. The MYCURSES option uses built-in ANSI (VT100)
301 escape sequences, and depends upon your terminal or console driver to
302 interpret them correctly.
304 In some C-Kermit builds, we replace printf() via #define printf...
305 However, this can cause conflicts with the [n]curses header files.
306 Various hacks are required to get around this -- see [59]ckutio.c,
307 [60]ckufio.c, [61]ckuusx.c, [62]ckucmd.c, etc.

315 Since version 5A, C-Kermit has included support for conversion of
316 character sets for Western European languages (i.e. languages that
317 originated in Western Europe, but are now also spoken in the Western
318 Hemisphere and other parts of the world), via ISO 8859-1 Latin Alphabet
319 1, for Eastern European languages (ISO Latin-2), Hebrew (and Yiddish),
320 Greek, and Cyrillic-alphabet languages (ISO Latin/Cyrillic). Many file
321 (local) character sets are supported: ISO 646 7-bit national sets, IBM
322 code pages, Apple, DEC, DG, NeXT, etc.
324 To build Kermit with no character-set translation at all, include
325 -DNOCSETS in the CFLAGS. To build with no Latin-2, add -DNOLATIN2. To
326 build with no Cyrillic, add -DNOCYRIL. To omit Hebrew, add -DNOHEBREW.
327 If -DNOCSETS is *not* included, you'll always get LATIN1. To build with
328 no KANJI include -DNOKANJI. There is presently no way to include
329 Latin-2, Cyrillic, Hebrew, or Kanji without also including Latin-1.
331 [69]Unicode support was added in C-Kermit 7.0, and it adds a fair
332 amount of tables and code (and this is only a "Level 1" implementation
333 -- a higher level would also require building in the entire Unicode
334 database). On a PC with RH 5.2 Linux, building C-Kermit 7.0, we get the
337 NOCSETS NOUNICODE NOKANJI Before After
338 [ ] [ ] [ ] 1329014 (Full)
339 [ ] [ ] [ X ] 1325686 (Unicode but no Kanji)
340 [ ] [ X ] [ ] 1158837 (All charsets except Unicode)
341 [ X ] [ x ] [ x ] 1090845 (NOCSETS implies the other two)
343 Note, by the way, that NOKANJI without NOUNICODE only removes the
344 non-Unicode Kanji sets (Shift-JIS, EUC-JP, JIS-7, etc). Kanji is still
345 representable in UCS-2 and UTF-8.

353 The Kermit CONNECT and INPUT commands are coded to execute Application
354 Program Command escape sequences from the host:
358 where <text> is a C-Kermit command, or a list of C-Kermit commands
359 separated by commas, up to about 1K in length.
361 To date, this feature has been included in the OS/2, Windows, VMS,
362 OS-9, and Unix versions, for which the symbol:
366 is defined automatically in [76]ckuusr.h. For OS/2, APC is enabled at
367 runtime by default, for UNIX it is disabled. It is controlled by the
368 SET TERMINAL APC command. Configuring APC capability into a version
369 that gets it by default (because CK_APC is defined in [77]ckuusr.h) can
370 be overridden by including:
374 on the CC command line.
376 C-Kermit's autodownload feature depends on the APC feature, so
377 deconfiguring APC also disables autodownload (it doesn't use APC escape
378 sequences, but uses the APC switching mechanism internally).

393 (Also see [88]Section 4)
395 Each release of C-Kermit is larger than the last. On some computers
396 (usually old ones) the size of the program prevents it from being
397 successfully linked and loaded. On some others (also usually old ones),
398 it occupies so much memory that it is constantly swapping or paging. In
399 such cases, you can reduce C-Kermit's size in various ways, outlined in
400 this section. The following options can cut down on the program's size
401 at compile time by removing features or changing the size of storage

405 quick-to-load Kermit file-transfer application for the remote end of
406 your connection, and the remote end is Unix based, take a look at
409 [89]http://www.columbia.edu/kermit/gkermit.html
411 6.1. Feature Selection
413 Features can be added or removed by defining symbols on the CC (C
414 compiler) command line. "-D" is the normal CC directive to define a
415 symbol so, for example, "-DNODEBUG" defines the symbol NODEBUG. Some C
416 compilers might use different syntax, e.g. "-d NODEBUG" or
417 "/DEFINE=NODEBUG". For C compilers that do not accept command-line
418 definitions, you can put the corresponding #define statements in the
419 file ckcsym.h, for example:

472 6.2. Changing Buffer Sizes
474 Most modern computers have so much memory that (a) there is no need to
475 scrimp and save, and (b) C-Kermit, even when fully configured, is
476 relatively small by today's standards.
478 Two major factors affect Kermit's size: feature selection and buffer
479 sizes. Buffer sizes affect such things as the maximum length for a
480 Kermit packet, the maximum length for a command, for a macro, for the
481 name of a macro, etc. Big buffer sizes are used when the following
486 as it is by default for most modern platforms (Linux, AIX 4 and 5,
487 HP-UX 10 and 11, Solaris, etc) in [90]ckuusr.h. If your build does not
488 get big buffers automatically (SHOW FEATURES tells you), you can
489 include them by rebuilding with BIGBUFOK defined; e.g. in Unix:
491 make xxxx KFLAGS=-DBIGBUFOK
493 where xxxx is the makefile target. On the other hand, if you want to
494 build without big buffers when they normally would be selected, use:
496 make xxxx KFLAGS=-DNOBIGBUF
498 There are options to control Kermit's packet buffer allocations. The
499 following symbols are defined in [91]ckcker.h in such a way that you
500 can override them by redefining them in CFLAGS:
502 -DMAXSP=xxxx - Maximum send-packet length.
503 -DMAXRP=xxxx - Maximum receive-packet length.
504 -DSBSIZ=xxxx - Total allocation for send-packet buffers.
505 -DRBSIZ=xxxx - Total allocation for receive-packet buffers.
507 The defaults depend on the platform.
509 Using dynamic allocation (-DDYNAMIC) reduces storage requirements for
510 the executable program on disk, and allows more and bigger packets at
511 runtime. This has proven safe over the years, and now most builds (e.g.
512 all Unix, VMS, Windows, and OS/2 ones) use dynamic memory allocation by
513 default. If it causes trouble, however, then omit the -DDYNAMIC option
514 from CFLAGS, or add -DNODYNAMIC.
516 6.3. Other Size-Related Items
518 To make Kermit compile and load successfully, you might have to change
519 your build procedure to:
521 a. Request a larger ("large" or "huge") compilation / code-generation
522 model. This is needed for 16-bit PC-based UNIX versions (most or
523 all of which fail to build C-Kermit 7.0 and later anyway). This is
524 typically done with a -M and/or -F switch (see your cc manual or
525 man page for details).
526 b. Some development systems support overlays. If the program is too
527 big to be built as is, check your loader manual ("man ld") to see
528 if an overlay feature is available. See the 2.10/2.11 BSD example
529 in the UNIX makefile. (Actually, as of version 7.0, C-Kermit is too
530 big to build, period, even with overlays, on 2.xx BSD).
531 c. Similarly, some small and/or segment-based architectures support
532 "code mapping", which is similar to overlays (PDP11-based VENIX
533 1.0, circa 1984, was an example). See the linker documentation on
534 the affected platform.
536 It is also possible to reduce the size of the executable program file
537 in several other ways:
539 a. Include the -O (optimize) compiler switch if it isn't already
540 included in your "make" entry (and if it works!). If your compiler
541 supports higher levels of optimization (e.g. -O2 or higher number,
542 -Onolimit (HP-UX), etc), try them; the greater the level of
543 optimization, the longer the compilation and more likely the
544 compiler will run out of memory. The the latter eventuality, some
545 compilers also provide command-line options to allocate more memory
546 for the optimizer, like "-Olimit number" in Ultrix.
547 b. If your platofrm supports shared libraries, change the make entry
548 to take advantage of this feature. The way to do this is, of
549 course, platform dependent; see the NeXT makefile target for an
550 example. some platforms (like Solaris) do it automatically and give
551 you no choice. But watch out: executables linked with shared
552 libraries are less portable than statically linked executables.
553 c. Strip the program image after building ("man strip" for further
554 info), or add -s to the LNKFLAGS (UNIX only). This strips the
555 program of its symbol table and relocation information.
556 d. Move character strings into a separate file. See the 2.11 BSD
557 target for an example.
559 6.4. Space/Time Tradeoffs
561 There are more than 6000 debug() statements in the program. If you want
562 to save both space (program size) and time (program execution time),
563 include -DNODEBUG in the compilation. If you want to include debugging
564 for tracking down problems, omit -DNODEBUG from the make entry. But
565 when you include debugging, you have two choices for how it's done. One
566 definition defines debug() to be a function call; this is cheap in
567 space but expensive in execution. The other defines debug as "if
568 (deblog)" and then the function call, to omit the function call
569 overhead when the debug log is not active. But this adds a lot of space
570 to the program. Both methods work, take your choice; IFDEBUG is
571 preferred if memory is not a constraint but the computer is likely to
572 be slow. The first method is the default, i.e. if nothing is done to
573 the CFLAGS or in [92]ckcdeb.h (but in some cases, e.g. VMS, it is). To
574 select the second method, include -DIFDEBUG in the compilation (and
575 don't include -DNODEBUG).

583 -DNODIAL removes automatic modem dialing completely, including the
584 entire [99]ckudia.c module, plus all commands that refer to dialing in
585 the various ckuus*.c modules.
587 -DMINIDIAL leaves the DIAL and related commands (SET/SHOW MODEM,
588 SET/SHOW DIAL) intact, but removes support for all types of modems
589 except CCITT, Hayes, Unknown, User-defined, Generic-high-speed, and
590 None (= Direct). The MINIDIAL option cuts the size of the dial module
591 approximately in half. Use this option if you have only Hayes or CCITT
592 modems and don't want to carry the baggage for the other types.
594 A compromise between full dialer support and MINIDIAL is obtained by
595 removing support for "old" modems -- all the strange non-Hayes
596 compatible 1200 and 2400 bps modems that C-Kermit has been carrying
597 around since 1985 or so. To remove support for these modems, add
598 -DNOOLDMODEMS to CFLAGS at compilation time.
600 Finally, if you keep support for old modems, you will notice that their
601 names appear on the "set modem ?" menu. That's because their names are,
602 by default, "visible". But the list is confusing to the younger
603 generation, who have only heard of modems from the V.32bis-and-later
604 era. If you want to be able to use old modems, but don't want their
605 names cluttering up menus, add this to CFLAGS:

619 8.3. [108]Other Networks
621 C-Kermit supports not only serial-port and modem connections, but also
622 TCP/IP and X.25 network connections. Some versions support other
623 network types too like DECnet, LAT, NETBIOS, etc. If you define the
628 then all network support is compiled away.

637 8.1.4. [112]Enabling Telnet NAWS
638 8.1.5. [113]Enabling Incoming TCP/IP Connections
639 8.1.6. [114]Disabling SET TCP Options
641 C-Kermit's TCP/IP features require the Berkeley sockets library or
642 equivalent, generally available on any Unix system, as well as in
643 Windows 9x/NT, OS/2, VMS, AOS/VS, VOS, etc. The TCP/IP support includes
644 built-in TELNET, FTP, and HTTP protocol. To select TCP/IP support,
645 include -DTCPSOCKET in your makefile target's CFLAGS, or (in VMS) the
646 appropriate variant (e.g. -DWOLLONGONG, -DMULTINET, -DEXCELAN,
649 The VMS and/or early Unix third-party TCP/IP products are often
650 incompatible with each other, and sometimes with different versions of
651 themselves. For example, Wollongong reportedly put header files in
652 different directories for different UNIX versions:
654 * in.h can be in either /usr/include/sys or /user/include/netinet.
655 * telnet.h can be in either /usr/include/arpa or
656 /user/include/netinet.
657 * inet.h can be in either /usr/include/arpa or /user/include/sys.
659 In cases like this, use the -I cc command-line option when possible;
660 otherwise it's better to make links in the file system than it is to
661 hack up the C-Kermit source code. Suppose, for example, Kermit is
662 looking for telnet.h in /usr/include/arpa, but on your computer it is
663 in /usr/include/netinet. Do this (as root, or get the system
664 administrator to do it):
667 ln /usr/include/netinet/telnet.h telnet.h
669 ("man ln" for details about links.)
671 The network support for TCP/IP and X.25 is in the source files
672 [115]ckcnet.h, [116]ckctel.c, [117]ckctel.c, [118]ckctel.h,
673 [119]ckcftp.c, with miscellaneous SHOW commands, etc, in the various
674 ckuus*.c modules, plus code in the ck*con.c or ckucns.c (CONNECT
675 command) and several other modules to detect TELNET negotiations, etc.
677 Within the TCPSOCKET code, some socket-level controls are included if
678 TCPSOCKET is defined in the C-Kermit CFLAGS and SOL_SOCKET is defined
679 in in the system's TCP-related header files, such as <sys/socket.h>.
687 In addition, if TCP_NODELAY is defined, the following command is also
690 SET TCP NODELAY (Nagle algorithm)
692 See the [120]C-Kermit user documentation for descriptions of these
697 There exist various types of firewalls, set up to separate users of an
698 internal TCP/IP network ("Intranet") from the great wide Internet, but
699 then to let selected users or services get through after all.
701 One firewall method is called SOCKS, in which a proxy server allows
702 users inside a firewall to access the outside world, based on a
703 permission list generally stored in a file. SOCKS is enabled in one of
704 two ways. First, the standard sockets library is modified to handle the
705 firewall, and then all the client applications are relinked (if
706 necessary, i.e. if the libraries are not dynamically loaded) with the
707 modified sockets library. The APIs are all the same, so the
708 applications do not need to be recoded or recompiled.
710 In the other method, the applications must be modified to call
711 replacement routines, such as Raccept() instead of accept(), Rbind()
712 instead of bind(), etc, and then linked with a separate SOCKS library.
713 This second method is accomplished (for SOCKS4) in C-Kermit by
714 including -DCK_SOCKS in your CFLAGS, and also adding:
718 to LIBS, or replacing -lsockets with -lsocks (depending on whether the
719 socks library also includes all the sockets entry points).
721 For SOCKS5, use -DCK_SOCKS5.
723 Explicit firewall support can, in general, not be a standard feature or
724 a feature that is selected at runtime, because the SOCKS library tends
725 to be different at each site -- local modifications abound.
727 The ideal situation occurs when firewalls are supported by the first
728 method, using dynamically linked sockets-replacement libraries; in this
729 case, all your TCP/IP client applications negotiate the firewall
732 8.1.2. Compilation and Linking Problems
734 If you get a compilation error in [121]ckcnet.c, with a complaint like
735 "incompatible types in assignment", it probably has something to do
736 with the data type your system uses for the inet_addr() function, which
737 is declared (usually) in <arpa/inet.h>. Kermit uses "unsigned long"
738 unless the symbol INADDRX is defined, in which case "struct inaddr" is
739 used instead. Try adding -DINADDRX to CFLAGS in your make entry, and if
740 that fixes the problem, please send a report to kermit@columbia.edu.
742 Compilation errors might also have to do with the data type used for
743 getsockopt() and setsockopt() option-length field. This is normally an
744 int, but sometimes it's a short, a long, or an unsigned any of those,
745 or a size_t. To fix the compilation problem, add -DSOCKOPT_T=xxx to the
746 CFLAGS in your makefile target, where xxx is the appropriate type (use
747 "man getsockopt" or grep through your system/network header files to
748 find the needed type).
750 8.1.3. Enabling Host Address Lists
752 When you give Kermit an IP host name, it calls the socket routine
753 gethostbyname() to resolve it. gethostbyname() returns a hostent
754 struct, which might or might not not include a list of addresses; if it
755 does, then if the first one fails, Kermit can try the second one, and
756 so on. However, this will only work if the symbol "h_addr" is a macro
757 defined as "h_addr_list[0]", usually in netdb.h. If it is, then you can
758 activate this feature by defining the following symbol in CFLAGS:
762 8.1.4. Enabling Telnet NAWS
764 The Telnet Negotiation About Window Size (NAWS) option requires the
765 ability to find out the terminal screen's dimensions. E.g. in Unix, we
766 need something like ioctl(0, TIOCGWINSZ, ...). If your version of
767 Kermit was built with NAWS capability, SHOW VERSIONS includes CK_NAWS
768 among the compiler options. If it doesn't, you can add it by defining
769 CK_NAWS at compile time. Then, if the compiler or linker complain about
770 undefined or missing symbols, or there is no complaint but SHOW
771 TERMINAL fails to show reasonable "Rows =, Columns =" values, then take
772 a look at (or write) the appropriate ttgwsiz() routine. On the other
773 hand, if CK_NAWS is defined by default for your system (in
774 [122]ckcnet.h), but causes trouble, you can override this definition by
775 including the -DNONAWS switch on your CC command line, thus disabling
778 This appears to be needed at least on the AT&T 3B2, where in
779 [123]ckutio.c, the routine ttgwsiz() finds that the TIOCGWINSZ symbol
780 is defined but lacks definitions for the corresponding winsize struct
781 and its members ws_col and ws_row.
783 The UNIX version of C-Kermit also traps SIGWINCH, so it can send a NAWS
784 to the Telnet server any time the local console terminal window size
785 changes, e.g. when you stretch it with a mouse. The SIGWINCH-trapping
786 code is enabled if SIGWINCH is defined (i.e. in signal.h). If this code
787 should cause problems, you can disable it without disabling the NAWS
788 feature altogether, by defining NOSIGWINCH at compile time.
790 8.1.5. Enabling Incoming TCP/IP Connections
792 This feature lets you "set host * port" and wait for an incoming
793 connection on the given port. This feature is enabled automatically at
794 compile if TCPSOCKET is defined and SELECT is also defined. But watch
795 out, simply defining SELECT on the cc command line does not guarantee
796 successful compilation or linking (see [124]Section 11).
798 If you want to disable incoming TCP/IP connections, then build C-Kermit
803 8.1.6. Disabling SET TCP Options
805 The main reason for this is because of header file / prototype
806 conflicts at compile time regardting get- / setsockopt(). If you can't
807 fix them (without breaking other builds), add the following in CFLAGS:
813 X.25 support requires (a) a Sun, (b) the SunLink product (libraries and
814 header files), and (c) an X.25 connection into your Sun. Similarly (in
815 C-Kermit 7.0 or later) Stratus VOS and IBM AIX.
817 In UNIX, special makefile targets sunos4x25 and sunos41x25 (for SUNOS
818 4.0 and 4.1, respectively), or aix41x25, are provided to build in this
819 feature, but they only work if conditions (a)-(c) are met. To request
820 this feature, include -DSUNX25 (or -DIBMX25) in CFLAGS.
822 SUNX25 (or -DIBMX25) and TCPSOCKET can be freely mixed and matched, and
823 selected by the user at runtime with the SET NETWORK TYPE command or
828 Support for other networking methods -- NETBIOS, LAT, Named Pipes, etc
829 -- is included in ck*net.h and ck*net.c for implementations (such as
830 Windows or OS/2) where these methods are supported.
832 Provision is made in the organization of the modules, header files,
833 commands, etc, for addition of new network types such as DECnet, X.25
834 for other systems (HP-UX, VMS, etc), and so on. Send email to
835 [125]kermit@columbia.edu if you are willing and able to work on such a

842 [ [128]Top ] [ [129]Contents ] [ [130]Next ] [ [131]Previous ]
844 The C language setjmp/longjmp mechanism is used for handling
845 exceptions. The jump buffer is of type jmp_buf, which almost everywhere
846 is typedef'd as an array, in which case you should have no trouble
847 compiling the exception-handling code. However, if you are building
848 C-Kermit in/for an environment where jmp_buf is something other than an
849 array (e.g. a struct), then you'll have to define the following symbol:

855 10. SECURITY FEATURES
857 [ [134]Top ] [ [135]Contents ] [ [136]Next ] [ [137]Previous ]
859 Security, in the sense of secure authentication and strong encryption,
860 can be built into versionf of C-Kermit for which the appropriate
861 libraries and header files are available (Kerberos IV, Kerberos V,
862 OpenSSL, SRP), as explained in great detail in the Kermit Security
864 . The following symbols govern C-Kermit's security features at build
868 Means do not configure any TELNET AUTHENTICATION support. It
869 implies NO_ENCRYPTION and undefines any of the auth and encrypt
870 types. It does not undefine CK_SSL even though builds with
871 CK_SSL cannot succeed without CK_AUTHENTICATION. (This will be
872 supported in a future release. It will be needed to allow
873 C-Kermit to be built only as an FTP client.)
876 Means do not compile in any KERBEROS support when
877 CK_AUTHENTICATION has been defined.
880 Do not compile in any SRP support when CK_AUTHENTICATION has
884 Do not compile in any SSL/TLS support
887 Do not compile in any Telnet encryption support. It does not
888 affect the use of SSL/TLS
891 Do not compile in any SSH support whether internal or external
894 Telnet AUTHENTICATION support. (Also, required if SSL/TLS
895 support is desired.) On most platforms this does not autodefine
896 any authentication mechanisms such as Kerberos V, Kerberos IV,
897 SRP, ... Those need to be defined separately.
900 Defined automatically when KRB4, KRB5, or KRB524 are defined.
901 Implies that some version of Kerberos is in use.
904 Should be defined when Kerberos IV support is desired.
907 Should be defined when Kerberos V support is desired.
910 Should be defined if both Kerberos V and Kerberos IV are used
911 and the Kerberos IV support is provided by the MIT Kerberos IV
912 compatibility library in the current Kerberos 5 distribution.
915 Should be defined if KRB5 is defined and Kerberos 5 User to User
919 Should be defined if Kerberos V support is provided by HEIMDAL.
920 Support for this option is not complete in C-Kermit 8.0. Anyone
921 interested in working on this should contact kermit-support.
924 Should be defined if SRP support is desired.
927 Should be defined if TELNET ENCRYPTION option support is
928 desired. This option does not define any particular encryption
929 types. That should be done by defining CK_DES or CK_CAST.
932 Should be defined if either DES or 3DES Telnet Encryption option
936 If CK_DES is defined and DES support is being provided by either
937 Eric Young's libdes.a or OpenSSL 0.9.6x or earlier, this option
938 must be defined. If it is not defined, it will be assumed that
939 DES support is provided by the MIT Kerberos IV libraries.
942 Should be defined if CAST Telnet Encryption option support is
946 Should be defined if SSL/TLS support (OpenSSL) is desired.
949 If KRB5 is defined, and OpenSSL is built to support the Kerberos
950 5 ciphers, then you should define SSL_KRB5
953 If you are using OpenSSL 0.9.7 or higher and do not wish to
954 build with support for Kerberos 5 TLS ciphers, this option must
958 If you are using OpenSSL 0.9.6 or higher and it has been
959 compiled with support for ZLIB compression, this option should
960 be defined to enable Kermit to properly enable the use of
964 Defined for C-Kermit to enable the use of external SSH clients
965 from the Kermit command language
968 Defined for Kermit implementations that have integrated SSH
969 support. Currently only Windows.
972 Defined if either SSHCMD or SSHBUILTIN are defined.
975 Telnet Send Location support.
978 Do not include Telnet Send Location support.
981 Telnet X-Display Location support. Determines if the X-Display
982 location information is sent to the Telnet server either via
983 Telnet XDISPLOC or NEW-ENV options.
986 Do not include Telnet X-Display Location support.
989 Telnet Forward X Windows Session Data option. Used to protect
990 the privacy and integrity of X Windows Sessions when secure
991 telnet sessions are in use.
994 Do not include Telnet Forward X Windows Session Data option.
996 Besides the strong forms of security listed above, C-Kermit also
997 embodies various internal security features, including:
1000 Compiling with the NOPUSH symbol defined removes all the "shell
1001 escape" features from the program, including the PUSH, RUN, and
1002 SPAWN commands, the "!" and "@" command prefixes, OPEN !READ,
1003 OPEN !WRITE, job control (including the SUSPEND command), the
1004 REDIRECT command, shell/DCL escape from CONNECT mode, as well as
1005 the server's execution of REMOTE HOST commands (and, of course,
1006 the ENABLE HOST command). Add NODISPO to also prevent acceptance
1007 of incoming MAIL or REMOTE PRINT files. For UNIX, also be sure
1008 to read [138]Section 11 of the [139]Unix C-Kermit Installation
1009 Instructions. about set[ug]id configuration. Additional
1010 restrictions can be enforced when in server mode; read about the
1011 DISABLE command in the user manual.
1014 Compiling with NOCCTRAP prevents the trapping of SIGINT by
1015 Kermit. Thus if the user generates a SIGINT signal (e.g. by
1016 typing the system's interrupt character), Kermit will exit
1017 immediately, rather than returning to its prompt.
1019 NOPUSH and NOCCTRAP together allow Kermit to be run from restricted
1020 shells, preventing access to system functions.

1024 11. ENABLING SELECT()
1026 [ [142]Top ] [ [143]Contents ] [ [144]Next ] [ [145]Previous ]
1028 Kermit works best if it can do nonblocking reads, nondestructive input
1029 buffer checking, and millisecond sleeps. All of these functions can be
1030 accomplished by the select() function, which, unfortunately, is not
1031 universally available. Furthermore, select() is required if incoming
1032 TCP/IP connections are to be supported.
1034 select() was introduced with Berkeley UNIX, rejected by AT&T for System
1035 V, but is gradually creeping in to all UNIX versions (and other
1036 operating systems too) by virtue of its presence in the sockets
1037 library, which is needed for TCP/IP. AT&T SVID for System V R4 includes
1038 select(), but that does not mean that all SVR4 implementations have it.
1040 Furthermore, even when select() is available, it might work only on
1041 socket file descriptors, but not on others like serial ports, pipes,
1042 etc. For example, in AOS/VS and BeOS, it works only with file
1043 descriptors that were created by socket() and opened by connect() or
1046 Other alternatives include poll() and rdchk(). Only one of these three
1047 functions should be included. The following symbols govern this:
1049 SELECT Use select() (BSD, or systems with sockets libraries)
1050 CK_POLL Use poll() (System V)
1051 RDCHK Use rdchk() (SCO XENIX and UNIX)
1053 If your system supports the select() function, but your version of
1054 C-Kermit does not, try adding:
1058 to the CFLAGS, and removing -DRDCHK or -DCK_POLL if it is there. If you
1059 get compilation errors, some adjustments to ck*tio.c and/or ck*net.c
1060 might be needed; search for SELECT (uppercase) in these files (note
1061 that there are several variations on the calling conventions for
1064 Various macros and data types need to be defined in order to use
1065 select(). Usually these are picked up from <types.h> or <sys/types.h>.
1066 But on some systems, they are in <sys/select.h>. In that case, add the
1071 to the CFLAGS to tell C-Kermit to #include <sys/select.h>. A good
1072 indication that you need to do this would be if you get compile-time
1073 complaints about "fd_set" or "FD_SET" not being declared or defined.
1075 In UNIX, the use of select() vs fork() in the CONNECT command is
1076 independent of the above considerations, and is governed by choosing a
1077 particular makefile target.
1079 As of C-Kermit 7.0, select() is also the preferred control mechanism
1080 for the CONNECT command. Unfortunately, the structures used by the
1081 original UNIX CONNECT command, based on fork(), and those used by
1082 select(), are so different, it was not practical to implement them both
1083 in one module. So the select()-based CONNECT command module for UNIX is
1084 [146]ckucns.c, and the fork-based one remains [147]ckucon.c. To choose
1085 the fork-based one, which is more portable (but slower and more
1086 fragile), use "wermit" as the make target. To choose the select-based
1087 one, use "xermit". Only do this if you can verify that the CONNECT
1088 command works on serial connections and PIPE connections as well as TCP
1091 The select()-based Unix CONNECT module, ckucns.c, must be used if
1092 encryption is to be done, since the fork() version (ckucon.c) loses
1093 its ability to share vital state information between the two forks.
1094 Also note that the select() version is superior in many other ways
1095 too. For example, it recovers better from exterior killing, forced
1096 disconnections, etc, plus it goes faster.
1098 SHOW VERSIONS tells whether the CONNECT module uses fork() or select().
1100 C-Kermit 8.0 adds learned script capability, which depends on select().
1101 All the "wermit" based targets (as opposed to "xermit") had NOLEARN
1102 added to them. Whenever changing a target over from wermit to xermit,
1103 also remember to remove NOLEARN.

1111 The REDIRECT command allows a local program to be run with its i/o
1112 redirected over the communications connection. Your version of C-Kermit
1113 has a REDIRECT command if it was built with the following CFLAG:
1117 This, in turn, is possible only if the underlying API is there. In the
1118 case of UNIX this is just the wait() system call, so all UNIX versions
1119 get this feature as of 6.0.192 (earlier versions needed a <sys/wait.h>
1120 header file defining the symbols WIFEXITED and WEXITSTATUS).
1122 As of version 7.0, file transfer can be done using pipes and filters.
1123 To enable this feature, #define PIPESEND (and fill in the code). To
1124 disable on systems where it is normally enabled, define NOPIPESEND.
1125 This feature is, of course, also disabled by building with NOPUSH (or
1126 giving the "nopush" command at runtime).
1128 C-Kermit 7.0 also adds the PIPE and SET HOST /COMMAND commands, which
1129 provide another form of redirection. This feature is selected with
1130 -DNETCMD. CK_RDIR must also be defined, since the same mechanisms are

1139 Floating-point support was added in C-Kermit 7.0.
1141 Floating-point numbers are enabled internally, at least for use in
1142 high-precision file-transfer timers and statistics, unless the
1143 following symbol is defined at compile time:
1147 This might be necessary on old PCs that do not have built-in
1148 floating-point hardware.
1150 When NOFLOAT is not defined, the following symbol tells which
1151 floating-point type to use:
1155 The value is either "double" (normal for 32- and 16-bit architectures)
1156 or "float" (normal for 64-bit architectures).
1158 C-Kermit can be configured to use high-precision file-transfer timers
1159 for more accurate statistics. This feature is enabled with:
1167 If you try to build with -DGFTIMER but you get compilation errors,
1168 either fix them (and send email to kermit@columbia.edu telling what you
1169 did), or else give up and use -DNOGFTIMER (or -DNOFLOAT) instead. Hint:
1170 depending on your machine architecture, you might have better luck
1171 using double than float as the data type for floating-point numbers, or
1172 vice versa. Look in [160]ckcdeb.h for the CKFLOAT definition.
1174 Floating-point arithmetic is also supported in the script programming
1175 language. First via the \fpp...() functions, such as \fppadd(), which
1176 adds two floating-point numbers, second in S-Expressions. Addition,
1177 subtraction, multiplication, and division are always available. But
1178 other functions such as logs, raising to powers, sines and cosines,
1179 etc, require the C Math library. To include user-level floating-point
1184 and in Unix you must link with the Math library:
1188 In K95 and VMS, FNFLOAT is defined automatically if CKFLOAT is defined.
1189 In Unix, however, FNFLOAT must be added to each makefile target
1190 individually, because of the special linking instructions that must
1191 also be added to each target.
1193 Note: S-Expressions require FNFLOAT.

1197 14. SPECIAL CONFIGURATIONS
1199 [ [163]Top ] [ [164]Contents ] [ [165]Previous ]
1201 As of C-Kermit 7.0, if you build C-Kermit normally, but with -DNOICP
1202 (No Interactive Command Parser), you get a program capable of making
1203 serial connections (but not dialing) and network connections (if
1204 TCPSOCKET or other network option included), and can also transfer
1205 files using Kermit protocol, but only via autodownload/upload.
1206 Furthermore, if you call the executable "telnet", it will act like
1207 Telnet -- using the command-line options. However, in this case there
1208 is nothing to escape back to, so if you type Ctrl-\c, it just prints a
1209 message to this effect.
1211 You can also build C-Kermit with -DNOXFER, meaning omit all the
1212 file-transfer features. This leaves you with a scriptable
1213 communications program that is considerably smaller than the full

1218 APPENDIX I: SUMMARY OF COMPILE-TIME OPTIONS
1220 [ [168]Top ] [ [169]Contents ]
1222 These are the symbols that can be specified on the cc command line,
1223 listed alphabetically. Others are used internally, including those
1224 taken from header files, those defined by the compiler itself, and
1225 those inferred from the ones given below. Kermit's SHOW VERSIONS
1226 command attempts to display most of these. See [170]ckcdeb.h and
1227 [171]ckcnet.h for inference rules. For example SVR3 implies ATTSV,
1228 MULTINET implies TCPSOCKET, and so on.
