English Applications

I installed proftpd on my opensuse 11.1 and since I needed a personal FTP server, I followed the steps on “THE PERFECT SERVER” series.

The Perfect Server - OpenSUSE 11.1 - Page 5 | HowtoForge - Linux Howtos and Tutorials

I installed proftpd-1.3.2a, and everything on the installation went perfect, but when I try to log, after accepting the user name and password, it stops and I have this output: (from filezilla)

Does anybody know how to resolve that MLSD problem?

Are you trying to connect to a server behind a NAT firewall? You need connection tracking rules to handle FTP servers. This can be done on Linux firewalls with the conntrack_ftp and nat_ftp modules but I don’t know how it would be done on a non-Linux firewall.

3

the only firewall I’m running is the one in Opensuse. how do I install and use those modules to allow the ftp server to run properly?

You need to load nf_conntrack_ftp. Add this to MODULES_LOADED_ON_BOOT in /etc/sysconfig/kernel.
