If I may ask, why the move from proFTPD to wu-FTPD? I believe the latter is less secure than the former. Is there something I am missing?
If you have followed the security lists in the last two years, there
hasn't been a single problem with wuftpd-2.4 since Thomas Biege made a
complete security audit of it.
proftpd isn't mature enough for high performance use. It has a severe
memory leak in the master daemon, the system call overhead is enormous (it
caused our ftp server to bump into max loads of around 60-90!), and my
description about stability lacks the right words. When I waded through
the code to fix these ugly performance problems (each daemon kills each
other daemon with SIGCONT, just to make sure it's alive. Wonderful...), I
fixed some format string bugs on the fly. Nono...
We needed per-ip connection limits, and now we got them (since xinetd has
a feature that can handle it).
Btw, does anybody know an ftp server that can throttle throughput?
