Proftpd

In order to limit how many directories up people can go add to /etc/proftpd/proftpd.conf:

DefaultRoot                     ~/../../

If you're having problems, set the debuglevel higher:

DebugLevel 3

If it's showing shit about IPv6 in syslog you can either put this in proftpd.conf

UseIPv6 off

and/or add the following to /etc/hosts

::1     ip6-localhost ip6-loopback localhost
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

If you're getting the following in syslog when you're trying to connect to localhost:
Jan  3 12:50:33 localhost proftpd[29974]: localhost (localhost[127.0.0.1]) - ProFTPD terminating (signal 11)
Jan  3 12:50:33 localhost proftpd[29974]: localhost (localhost[127.0.0.1]) - FTP session closed.
or
Jan  3 12:49:27 localhost proftpd[29944]: localhost (localhost[::ffff:127.0.0.1]) - ProFTPD terminating (signal 11)
Jan  3 12:49:27 localhost proftpd[29944]: localhost (localhost[::ffff:127.0.0.1]) - FTP session closed.
and the terminal immediately disconnects with a service terminated message


a possible solution is to set
DelayEngine                    off
(didn't work for me)

or check /etc/proftpd/modules.conf and turn off some modules. For me
#LoadModule mod_sql.c
was doing it.

There are two values for ServerType: inetd and standalone. Remember to edit /etc/inetd.conf and restart inetd if you want to go standalone.
