- 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.
libskey contains references to _crypt and can't resolve it unless
-lcrypt occurs after it in the link command. This only occurs when
linking statically.
(as is printing out a version number at the telnet login banner).
Don't print out /etc/motd when people login, instead if present,
print out /etc/ftpmotd. It looks like 4.4lite2 has done something similar
(perhaps for different reasons) because /etc/motd no longer shows up
on vangogh.
Folks who like the old behavior can create a symbolic link to motd.
