infrastructure and using that infrastructure in programs.
* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
of the infratsructure (libraries, support programs, etc.)
* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
building of support for using the corresponding API
in various libraries/programs that can use it.
As discussed on tech-toolchain.
- mlst shouldn't return cdir or pdir for type, only dir
- mlst should always provide a full path name
- mlsd should provide a full path name for the cdir entry. (providing a
full path name for the pdir entry is optional, and i punted on that).
and with a non-NULL file pointer. active transfers now work correctly again,
passive transfers work, and the data stream is only closed after a PASV or
EPSV if a successful connection was initiated with dataconn().
descriptor was set by dataconn(). this fixes a problem for clients (such
as lynx and netscape) that only sent PASV/EPSV after a transfer (RETR, LIST,
STOR) started and returned 150. certain command sequences could return 550
(etc) before setting up the dataconn(), and would run into this bug. netbsd's
ftp didn't hit this bug because it always sends PASV/EPSV before a new
transfer command.
- 'denyquick'; deny a connection so tagged by ftpusers(5) after the USER
command instead of the PASS command. whilst this might provide some
info leakage of accounts names if you have some `real' or `chroot'
users enabled and not others, it does prevent accidental entering of
such passwords if you have all such users denied. This option is
strongly recommended on anonymous-only servers.
Functionality requested by Rob Windsor in [bin/12602]
- 'private'; don't display class related information in the output of STAT.
For paranoid admins.
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).
Improved by comments from enami and christos -- thanks!
Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
- totally clear a glob buffer before use, because FreeBSD depends on
some of the other fields being cleared (other than just gl_offs)
- in strend(), ensure that the source string isn't too large
- remove unnecessarily complicated sizing of proctitle, since snprintf()
will truncate it anyway
define HAVE_SETPROCTITLE and HAVE_SOCKADDR_SA_LEN, because certain
operating systems from a vendor which claims to be the biggest unix
vendor as of two months ago #define BSD4_4 and THEN REMOVE BITS OF THE
4.4BSD API!
anyway, this won't affect other systems which use lukemftpd (e.g,
other 4.4BSD derived systems), because autoconf will set HAVE_SETPROCTITLE
as appropriate. the point of this little code fragment is to remove the
need to have -DHAVE_SETPROCTITLE ... in our libexec/ftpd/Makefile

This involved changing the yacc syntax to be line-oriented, rather than
having it run against the entire input at once, and adding a flag to
struct tab, to indicate if or not it's acceptable for a command to occur
OOB.
* Add ftpd.conf(5) directive `advertise'; change the address that is
advertised to the client for PASV transfers. this may be useful in
certain firewall/NAT environments.
Feature requested in [bin/9606] by Scott Presnell.
* Add -X option; syslog wu-ftpd style xferlog messages, prefixed with
`xferlog: '. An example line from syslog (wrapped):
Dec 16 18:50:24 odysseus ftpd[571]: xferlog: Sat Dec 16 18:50:24 2000
2 localhost 3747328 /pub/WLW2K601.EXE b _ o a lukem@ FTP 0 * c
These messages can be converted to a wu-ftpd style xferlog file
suitable for parsing with third-party tools with something like:
grep 'xferlog: ' /var/log/xferlog | \
sed -e 's/^.*xferlog: //' >wuxferlog
The format is the same as the wu-ftpd xferlog entries (with the leading
syslog stuff), but different from the wu-ftpd syslogged xferlog entries
because the latter is not as easy to convert into the standard xferlog
file format.
The choice to only syslog the xferlog messages rather than append to
a /var/log/xferlog file was made because the latter doesn't work to
well in the situation where the logfile is rotated and compressed and
a long-running ftpd still has a file-descriptor to the now nonexistant
xferlog file, and the log message will then get lost.
Feature requested in [bin/11651] by Hubert Feyrer.
Fixes:
* In ftpd(8), clarify the -a and -c options.
* More clarifications in ftpd.conf(5).
* Ensure that all ftpd.conf commands set a parameter back to sane defaults
if an argument of `none' or bad settings are given.
* Support the `chroot' directive for `REAL' users too (for consistency).
* For `GUEST' users, store the supplied password in pw->pw_passwd for use
later in the xferlog.
* If show_chdir_messages() is given a code of -1, flush the cache of
visited directories. Invoke show_chdir_messages(-1) in end_login().
* Only syslog session stats if logging is requested.
* Rename logcmd() -> logxfer(), and dolog() -> logremotehost().
* Use cprintf() instead of fprintf() where appropriate.
* Minor KNF, and make a couple of functions static that were declared static.
in porting to other systems.
- don't syslog() or setproctitle() "ACCT" lines (as per "PASS")
- replace #ifdef HASSETPROCTITLE with #if HAVE_SETPROCTITLE, and set the
latter #ifdef BSD4_4
- don't compile in internal `ls' #ifdef NO_INTERNAL_LS. will need Makefile
support if this is to be used on NetBSD.
