Using the default "basic.conf" file with a 1.2.0pre10 installation on Slackware Linux 7 (2.2.14), proftpd has problems with all of the aliased interfaces on the box. The daemon will start up and listen on port 21 on all of the interfaces, however if I connect to any of the aliased interfaces, the log shows a bind(): Permission Denied and the connection closes. The primary and localhost interface will accept connections with no problems. The daemon is running as nobody:nogroup, and those users exist on the system. Incedintally, if I run the daemon as root, proftpd works fine on ALL configured interfaces, however running the daemon as root is not desired. I have had no problems running any versions previous to pre10 on the same machine and on other machines as well. Anyone knows why am I getting this error??

See the SocketBindTight directive. When off (the default), sockets are bound to 0.0.0.0:port. When on, specific IPs are used (as specified by VirtualHost) and the "main" IP is guessed. You can also use the port 0 trick to prevent binding the the main guessed IP.
