FTP on Linux Freezes on command – ls
Something that I was suffering from when I tried to use ftp on linux, everytime I tried to do ‘ls’ to list the files FTP would freeze and not seem to do anything.
After quite a lot of pain, I noticed that a few of the important modules had not been loaded for the firewall – IPTABLES. You must have the following modules loaded or built into your kernel for FTP to work through the firewall …
- ip_conntrack
- ip_conntrack_ftp
- ip_nat_ftp
if you want to load them as modules then use modprobe.
