any case.
It makes no difference for anon account (since chroot already makes it GMT),
but if you do mirror with special non-anon login, in old variant
your mirror will be wholy retransmitted twice in the year due to
time zone changes (/etc/localtime plays bad role here)
modules from src/bin/ls, and handling exec(_PATH_LS,..) as a
special case, very useful in an environment where many users
are given chroot access. "~/etc/{s}pwd.db" files are still
needed if uid/gid->user/group translation is desired.
To enable this it must be compiled with the make variable
FTP_INTERNAL_LS defined, either in /etc/make.conf or the
environment.
- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.
- Check for failure where no checks were present.
Discussed with: bde
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
password: ask for it, but don't tell that S/key password required.
It looks like non-s/key system from outside.
Additionally tell that s/key required when it is so for normal case
It happens if 1) regular passwords not allowed, 2) skey database
not activated for given user.
Under some rare circumstanes skey_challenge can return empty
diagnostic or even previous buffer, fix it.
Document the new -R (relax paranoia) option.
From NetBSD/Lite2: code and man page cleanups, Kerberos IV hooks
(relax, we're still exportable), and /etc/ftpchroot feature for
semi-anonymous accounts
or addresses other than the requestor's address. This violates the FTP
protocol (hmm...as I write this, I'm going to change this to a run-time var.)
Require login before PASV and RNTO commands.
Close unused PASV ports so they don't hang around forever.
Do not allow file overwrites via rename or STOR when anonymous
(suspenders).
Clean up buffer utilization.
My code, but heavily inspired by Hobbit's changes to wu-ftpd as pointed out
by Mike Prettejohn and Kit Knox.
accepting connections on the FTP port and forking children processes to
handling them. This is lower overhead than spawning ftpd from inetd and
can be a significant win on busy FTP servers. Be sure to disable ftpd in
inetd.conf if you decide to use this option.
These changes are based on similar changes I made to wu-ftpd and have
been in use on wcarchive for several months.
- set TCP_NOPUSH to keep from sending short packets at each write(2) boundary
- set SO_SNDBUF to 64k so we have a reasonable amount of buffer space
- for a regular file in binary mode which is not being restarted and is
. smaller than 16 Meg, use mmap(2) and write(2) the whole file in one big
gulp
In the most common circumstances, this should dramatically reduce the
system-call load from ftpd, since the call to write() will not return until
the entire file has been written, rather than writing just a few K at a time
in a loop.
