[Sussex] Security and Network Problems [WAS: FTP - Fedora core 3]

[Brendan Whelan]

Jon,

Thanks for the offer of checking my configuration - the information is at
the bottom of this email.

Also, I need to restrict the FTP users to their home directory i.e. so that
they can read, write and delete in their home directory but cannot move
around my system. I have tried various combinations of user/group/other for
the directories but I either prevent the user from getting to their home or
they can wander around my directories.

I have:
/home/ftp_users/user_1
/home/ftp_users/user_2 etc

Many thanks,

Brendan
