Ls doesn't work from ftp

[Kris Spander]

Hello experts,

I am having a funny problem. If I ftp into my server as a regular user, ls works fine but if I do the same thing as "anonymous" then the ls command fails. Before you say anything, there is an ls under /home/ftp/usr/bin, the permissions are ok, and I can execute /home/ftp/usr/bin/ls from the shell. What could possibly explain this?

TIA, Kris

Hi Kris:

This is easy (I think). Copy /sbin/ls to home/ftp/usr/bin and I think your problem will disappear.

Hi (again):

I suppose I should explain. When you initiate anonymous ftp it does a chroot() to ftp's home directory. I'll bet you copied /usr/bin/ls and it requires some libraries in /usr to execute. The version is /sbin is statically linked and thus will execute without any other assistance.

Hi Clay,

Yep, that did it. Thanks for the quick answer. This place rocks!!!
