use it to disable extended passive mode when your firewall is obnoxious.
This did in fact solve a problem I was having with a firewall at work, and
the status message was taken directly from a problem session fixed by this.
elapsed time. (suggested by simonb)
- actually display transfer stats after a URL fetch. (bug introduced a
*long* time ago)
- update copyright & version
From Hajimu UMEMOTO, via Mike Heffner of FreeBSD.
(FreeBSD has imported NetBSD's ftp as their ftp client;
Mike is sending back some of their local changes).
- add -N netrc and $NETRC, as methods to select an alternative .netrc file
- cache local user name and home directory for further use
- in mget(), use docase() instead of a local version to do the case
conversion.
(from RFC 2389).
add support for MLST & MLSD (machine parseble listings) with 'mlst', 'mlsd'
and 'pmlsd' (mlsd |$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().
- ftp(1): treats IPv4 mapped destination as IPv4 peer, not native IPv6 peer.
this does not support network with SIIT translator.
- rshd(8)/rlogind(8): rejects accesses from IPv4 mapped peer, to avoid
possible abuse of IPv4 mapped addr (rshd/rlogind use source address-based
auth so it is important to check the condition).
Now that after many years on not caring we find certain popular
ftp servers are starting to obey RFC959 to the letter of the law
and will only return a list of filenames (not directories or
other filetypes) in the output of `NLST', then `LIST' is more useful
in this case. (Note that the aforementioned pedanticness means that
filename completion isn't as useful as it could be...)
Fixes [bin/8937] by David A. Gatwood <dgatwood@deepspace.mklinux.org>
for listings of the current working directory; some ftp servers don't
like `NLST .'.
[noted by Giles Lean <giles@nemeton.com.au>]
* recvrequest(): treat remote=="" as remote==NULL when calling command().
(to support the above change)
* support `[user@]' in `[user@]host' and `[user@]host[:][path]'.
[based on idea (and initial code) from David Maxwell <david@fundy.ca>]
* `idle' may be invoked without any args
* reformat some comments
* reformat usage string in program and man page
* call updateremotepwd() after successful login, not after successful connect
* always call setsockopt(, IPPROTO_IP, IP_TOS, ) (et al); using #if
defined(IPPROTO_IP) doesn't work on certain foreign systems where
enums instead of #defines are used...

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'
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
- 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.
* confirm(): move from util.c to cmds.c. display mnemonic string in its prompt.
add support for `q' (terminate current xfer), `?' (show help list)
* in various signal handlers, output a linefeed only if fromatty.
* if fgets(stdin) returned NULL (i.e, EOF), clearerr(stdin) because you don't
want future fgets to fail. this is not done for the fgets() in the main
command loop, since ftp will quit at that point.
* unless ftp is invoked with -a, don't retain the anonftp setting between
hosts (`ftp somehost:' sets anonftp, but you don't want that to `stick'
if you close that connection and open a new one).
prints out info if bytes > 0). only set the handler if SIGINFO is defined
* hijack SIGQUIT to be the same as SIGINFO (foreign ports have this, and it's
annoying to have SIGQUIT dump core on netbsd when it prints info on other
systems)
* in {recv,send}request(), factor a lot of duplicated code out into a
`cleanup' section at the end
* rework shell() a bit
* 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
the disabled state can be overridden by toggling epsv4.
(I got sick of the errors about EPSV not being supported on almost
every server I connect to. This way we retain support for epsv4, but
it's not so whiny after the first failure...)
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
* 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.
the an empty directory (e.g, between `some' and `path' in
`ftp://host/some//path'), then execute `CWD ' (without a path).
This command will probably fail on rfc 959 compliant servers, so
issue a warning in this case and bail. [noted by cgd].
(i wonder if the people who wrote rfc 1738 actually realised that this
requirement appears to contravene the spec for `cwd' in rfc 959 ?)
* replace isurl() with isipv6addr(), and use appropriately. fixes
auto-login with `classic ftp URLs' (e.g, `ftp somehost:')
* cleanup and rework some of the ipv6 stuff in parse_url()
* prevent potential coredump in fetch_ftp() when parsing `;type=X'
* KNF a few lines
* fix a couple of comments
* cleanup the man page a bit
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.
