2023-02-25Add option sslnoverify to control validation of SSL certificates.mlelstv
Add netrc processing to fetch-mode (URL on command line) to enable options and autologin via netrc. Fix SSL cleanup in some error paths. Certificate validation is now enabled by default. Set FTPSSLNOVERIFY=1 in environment or configure a corresponding init macro via netrc to not validate certs (required if you haven't installed a required CA certificate for OpenSSL). Discussed with lukem@ on icb.

2000-11-15- implement "mreget"; as per "mget" but uses "reget" instead of "get"lukem
- add -N netrc and $NETRC, as methods to select an alternative .netrc file - cache local user name and home directory for further use - in mget(), use docase() instead of a local version to do the case conversion.
2000-09-14since everything else here uses ANSI C, we might as well replace __STRING()lukem

2000-07-28rename "opts" to "remopts", so people used to "o host" don't get bitten...lukem
2000-07-18add support for FEAT and OPTS commands with `features' and `opts'.lukem
(from RFC 2389). add support for MLST & MLSD (machine parseble listings) with 'mlst', 'mlsd' and 'pmlsd' (mlsd |$PAGER) commands. (from draft-ietf-ftpext-mlst-11) rename remotesyst() to getremoteinfo(), and modify to parse the result from FEAT (if supported), and take into account the support for the various extensions such as MDTM, SIZE, REST (STREAM), MLSD, and FEAT/OPTS. put each feature into one of the following categories: - known to work (explicit FEAT) - unknown but assume works until explicit failure, when it's then tagged as `known not to work'. - known not to work (FEAT succeeded but didn't return anything, or was unknown and then explicit failure) assign results into features[] matrix. add support to getreply() so that an optional callback will be called for each line received from the server except for the first and last. this is used in FEAT (and MLST) parsing. modify various commands to check if REST (STREAM), MDTM and SIZE are explicitly or implicitly supported before using. fix `syst' when verbose is off. minor knf (indent goto labels by one space, etc). simply various command usage handlers by assuming that argv != NULL except for quit() and disconnect().
2000-05-01* Add support for `fget localfile', which reads a list of filenames tolukem
retrieve from localfile. Based on work by Darren Reed. * Crank version. * Update copyright dates.
1999-11-12- implement `set rprompt'; right side version of `set prompt'. depends onlukem
EL_RPROMPT support i added to editline(3). - allow $FTPPROMPT and $FTPRPROMPT to override defaults for the relevant prompts - move `%' formatting code from prompt() to expandbuf(). - implement `%.' and `%c', similar to the same % codes in tcsh(1) (functionality I added to tcsh nearly 6 years ago), except that `%.' always does `...trailing' and `%c' always does `/<x>trailing'. - unknown `%foo' codes get printed as `%foo'
1999-11-11- implement updateremotepwd(); update the global variable `remotepwd'lukem
to contain the remote working directory. - add `set prompt', a user configurable prompt. (defaults to `ftp> '). the following escape characters a la tcsh(1) are supported: %/, %m, %M, and %n. - add global var `username'; used by prompt code - fix a couple of minor memory leaks - bump version
1999-10-24new features:lukem
- add `usage'; displays the usage of a command. implemented by calling the c_handler() with argc = 0, argv = "funcname". - add `passive auto'; does the same as $FTPMODE=auto. - add `set [option value]'; display all options, or set an option to a value. - add `unset option'; unset an option. - add getoptionvalue() to retrieve an option's value, and replace a few global variables with calls to this. - implement cleanuppeer(), which resets various bits of state back to `disconnected'. call in disconnect() and lostpeer(). - support completing on `options'. - improve recovery after a SIGINT may have closed the connection. XXX: there's still a couple to fix other stuff: - various consistency fixes in the man page. - ensure that the command usage strings in the code and man page match reality. - mput/mget: check that the connection still exists before each xfer. - minor cosmetic changes in confirm(). - set code correctly in sizecmd() and modtime() - don't need \n in err() strings. - change lostpeer to take an argument (rather than casting (sig_t)lostpeer in signal handlers) - knf and whitespace police.

1999-10-05enhancments from Marc Horowitz <marc@mit.edu> to improve connection timeouts:lukem
* implement xsignal_restart(), which only sets the SA_RESTART flag if specifically requested * xsignal() is now a wrapper to xsignal_restart(). INFO, USR1, USR2 and WINCH are restartable, ALRM, INT, PIPE and QUIT are not. * improve getreply()'s timeout code to take advantage of the above. other changes: * improve wording of how globbing works for `classic' URLs (host:path). suggested by John Refling <johnr@imageworks.com> in relation to PRs [bin/8519] and [bin/8520] * always compile in the `edit' command even if NO_EDITCOMPLETE defined. it's just a no-op in the latter case, which is more consistent to the users. * always compile in about: support (i.e, remove NO_ABOUT). i'm entitled to some vanity in this program... * clean up some whitespace
1999-10-01* newer takes an optional second arg, so document thislukem
* be a bit more explicit that the arguments to rate are in bytes
1999-09-28* add new commands:lukem
lpage page local files pdir as dir, but through your $PAGER pls as ls, but through your $PAGER * implement docase() (a la dotrans() et al) and use appropriately, rototilling some duplicated code * globulize(): modify to return a pointer to the strdup()ed result in all cases, and hack the code that calls it to take this into account * replace strcpy() and strncpy() with strlcpy() * put(), getit(): use some aptly named local vars instead of argv[...] * delint
1999-09-27* idle(): rename to idlecmd(). certain linux distributions have an incompatiblelukem
prototype for idle() in <unistd.h> (which i thought was against namespace and sensibility guidelines, but...) * consistently use xsignal() instead of signal(). we get known behaviour in all cases (SA_RESTART), which is good for some borken foreign systems. * remove signal.h from most files; it's unnecessary now * fetch_url(): use `long chunksize' instead of ssize_t; it's more portable, and we're setting chunksize with strtol() anyway * xsignal(): only use SA_RESTART if it exists. SunOS 4.x doesn't have it but has the inverse (SA_INTERRUPT). the original function i was inspired from had this support (lib/signal.c, W. Richard Stevens' `UNP 2nd ed Vol 1'). * remove <termios.h> from util.c; it should be unnecessary now
1999-09-22* add support for `xferbuf', which sets both `sndbuf' and `rcvbuf'lukem
* document the above three commands * rototill the way the sndbuf and rcvbuf work. remove resetsockbufsize() * use the appropriate socket buffer size as the size of the buffer that the read()/write() loops use. speeds up things in some cases.
1999-07-11add epsv4 command, which enable/disable the use of EPSV/EPRT.itojun
this is mainly for (hypothetical) ftp server which disconnect clients that use EPSV/EPRT. I've never seen any ftp server like this, but epsv4 command may be of use when such an ftp server is found.
1999-07-02add dual-stack (IPv4/v6) support. hope I broke no other part...itojun
1999-06-29[fear this; more ftp hacking from lukem :-]lukem
features: --------- * transfer rate throttling with the new `rate' command. syntax: rate direction [max [incr]] where direction is `all', `get' or `put'. if max is not supplied, the current settings are displayed. if max is supplied, then transfers in the given direction will be throttled to this value. if incr is supplied, the increment for the `on-the-fly' scaling will be set to that, otherwise `1024' is used. currently implemented for binary get, binary put, and url fetches. not yet supported for ascii get or put, or local file copies. * on-the-fly scaling of the throttle based on signals: - SIGUSR1 raises the throttle rate by the increment for that direction - SIGUSR2 lowers the throttle rate by the increment for that direction * -T dir,max[,incr] option to set rate from the command line * `k', `m', `g' suffix support for bytecounts in the `hash', `rate', `rcvbuf' and `sndbuf' commands) bug fixes and code mods: ------------------------ * fix up ftp_login() so that ruserpass() is always called, even for command-line url fetches. * implement strsuftoi(), which parses a given number into a int with suffix support. replaces getsockbufsize() * implement parserate(), which does the argv parsing for -T and rate * save and restore errno in signal handlers (may not be necessary, but it doesn't hurt) notes: ------ the rate command has had reasonable testing, but I'd like feedback if it doesn't do the right thing, especially from people on slower (i.e, modem) links. I haven't tested the rate throttle against a http server which does `transfer-encoding: chunked' because I couldn't find a server to test against.
1999-06-24include <signal.h> explicitly! we use sig_t extern.h, and we cannotchristos
depend on other headers fetching it on other OS's.
1999-06-20split the "SMALL" #ifdefs into ones for NO_ABOUT, NO_EDITCOMPLETE, andcgd
NO_PROGRESS. -DSMALL still implies all of those. progress meter support isn't necessary for the smallest possible ftp client, but it adds very little space and makes users' lives much better. Therefore, it should be enabled for installation media if at all possible.
1999-03-08whitespace & copyright fixeslukem
1998-07-26* spell `retrieved' correctly!lukem
* parse Last-Modified: HTTP headers for date, and change time of retrieved file if parsing succeeded * support file:/// and file://localhost/ URLs * in url_get(), re-write byte moving code to consistently use fread() and fwrite(), and check errors at end with ferror() * add about:* easter-egg (#ifndef SMALL :-)
1998-07-10Add "sndbuf" and "rcvbuf" commands for setting the socket buffer sizes,thorpej
which in turn can allow the use of larger TCP windows. This is a work in progress; there is not yet support for specifying global defaults or user prefrences on a host/network basis.
1997-08-18bugs fixed:lukem
* don't interpret '-' or '|' when a local filename is determined from the remote name (i.e, in mget, and in get with only one argument). This is implemented using an extra argument to recvrequest(). Fixes a major security hole. * clean up memory leak when using globulize() * clean up a couple of comments * fix wording in TNF copyright features added: * support for TIS fwtk gate-ftp servers: * read defaults from $FTPSERVER && $FTPSERVERPORT * start in gate-ftp mode if invoked as 'gate-ftp' * toggle or set with 'gate [host [port]]'
1997-07-20* use RCSID() && COPYRIGHT() macroslukem
* cleanup for WARNS=1 (including some ugly '(void)&var' bits wrapped in #ifdef __GNUC__ to shut up gcc warnings WRT setjmp/longjmp) * use strtol() instead of atoi(), and more extensively check result of conversion * use u_int16_t instead of short or int for TCP port addresses
1997-04-05* support $ftp_proxy for ftp:// transfers [bin/3245]lukem
* add "more" & "less" as synonyms for "page" * move editline setup code into controlediting(), and call appropriately. only setup setup terminal if going into interactive mode. inspired by Todd Miller <todd.miller@courtesan.com>
1997-03-14SMALLFTP->SMALL; remove SMALL from Makefilechristos
1997-03-13Features:lukem
* support remglobbing of auto_fetch arguments * new flag - '-e'; disable editing * "page file" == "get file |${PAGER-less}" Bugfixes/cleanup: * consistently use a trailing '.' on messages * code cleanup, including buffer overrun fixes, use puts and putchar in places, etc (inspired by OpenBSD mods) * disable progress bar when local-file is a pipe or '-' * skip \r in http headers * fix remote ftpd slash bug more elegantly (so it works with ////) * abort_remote(): check if cout==NULL before using it. should fix [bin/3273] * fixed up cosmetic problems when complete_remote() generated errors from the remote server (such as "no files found", "login with user and pass", ...) done by adding extra argument to remglob(), which is a pointer to an error buffer to put messages in rather than printing to stdout.
1997-01-19New features:lukem
* Command line editing via editline(3) library. * Context sensitive command and file completion, including remote files. Enhancements to auto-fetch feature: * Support for http:// URLs using the http protocol, including proxy HTTP support via $htty_proxy if it's defined. * The connection is kept open between successive files on the same host. (obviously, this does not count for http requests.) * Return value of ftp is 0 on no error, or the offset in argv[] of the file which failed (i.e., argv[x] failed, ftp returns x). * If the path in an ftp URL or classic format line has a trailing '/', cd to the path and enter interactive mode. Fixes [bin/3011], albiet requiring the user to help ftp in determining the operation. Other changes: * '-P port' works for normal ftp, and is the default for all classic style auto-fetch transfers and for ftp URLs that don't specify the port. (previously it would just work for the first xfer.) * Some code moved into separated files along logical divisions. * Editing and completion can be compiled out with -DSMALLFTP.

1996-12-06functionality mods:lukem
* implement 'progress bar/meter' (inspired by ncftp). use 'progress' to toggle on. it will display current file size to 5 digits, automatically determining suffix (up to 16384 P (petabytes) == 2^64). * 'ls' now uses NLST (unadorned listing), a la older ftp clients. 'dir' still does LIST (long listing). idea from John Nemeth <jnemeth@cue.bc.ca> bug fixes: * return first line of reply in reply_string[] from getreply(), instead of last line. This fixes [bin/741] (parsing of SYST), and also means that SIZE and MDTM messages will be parsed correctly if they're longer than 1 line. * parse URL-style auto-ftps that have no filename correctly (e.g, ftp://host, ftp://host/, ftp://host/dir/). pointed out by Jaromir Dolecek <dolecek@saruman.ics.muni.cz> * pass the correct size array in 2nd arg of utimes() when setting the modification time
1996-11-28More features, some of which were inspired by changes thatlukem
friedman@gnu.ai.mit.edu (Noah Friedman) made to his modified ftp: - implement "lpwd" - local pwd - implement "preserve" - toggle preserving of file modification times on retrieved files - allow for explicit "on" or "off" arg to toggle commands - "exit" synonym for "quit", "msend" synonym for "mput" - in confirmation mode, allow 'a' (yes to rest of current command), and 'p' (turn off prompt mode, as if 'prompt off' was done, effective immediately) - "modtime" returns time formatted as localtime, not GMT Bug fixes: - check for extraneous args on commands - cleanup const usage, line formatting - create 0 length temporary file in remglob() to prevent symlink games (from OpenBSD) - check length of filename of ~/.netrc (from OpenBSD)
1996-11-25Correct the connecthelp info. This is really ftp, not tftp.fvdl
1996-11-25cleanups/bugfixes:lukem
- don't echo 'ACCT' parameter when debugging (a la 'PASS') - Fix checking of directory access for "/foo", the parent directory is "/", not "" (from FreeBSD) - remove trailing whitespace on lines - add any missing NetBSD tags - cleanups to man page, includinging sorting options description feature additions: - variable sized hash marks (from [bin/683], but done in the hash command as an optional arg) - more user-friendly transfer time printing (from FreeBSD, with mods) - '-p' command line option to jump into PASV mode (closes [bin/2857], but with an option rather than checking argv[0]) - SIGINFO support for printing xfer stats when sending/receiving requests - '-P port' for changing the port to connect to (from thorpej@netbsd.org) - '-a': bypass normal login, and try anonymous login (from OpenBSD via thorpej) - autofetch files via url (ftp://...) or "classic" (host:/file) (from OpenBSD via thorpej) - 'ftp' synonymous with 'open' (from FreeBSD)
