I enabled users to use jailed shell command line interface for websites. So far, this works fine, the user can ssh to his jailed website, use the shell, editors and so: Code: user@hisdesktop:~$ ssh email@example.com firstname.lastname@example.org's password: email@example.com:~$ firstname.lastname@example.org:~$ ls /web/ error favicon.ico index.html robots.txt stats However, if he tries to ssh from his jailed environment outside to some other server, it doesn't work. The same happes if he tries to use scp: Code: email@example.com:~$ ssh firstname.lastname@example.org You don't exist, go away! email@example.com:~$ scp firstname.lastname@example.org:some/file.txt . unknown user 5004 Why? How to make it work? Tested on fully updated fresh install of: Ubuntu server 12.04.3 LTS (64bit) Jailkit-2.17 used as chroot shell ISPConfig 188.8.131.52 Installed following The Perfect Server - Ubuntu 12.04 LTS (Apache2, BIND, Dovecot, ISPConfig 3) tutorial.
