A jailed shell-user created with ISPConfig3 can no longer operate. After login the user gets this error: /usr/bin/lesspipe: line 262: [: =: unary operator expected trying to execute some commands like "ls" he gets: Segmentation fault Other similar users and root continue to operate normally. I tried to delete and recreate the problematic user without success. Any help would be appreciated. Debian 7 - ISPConfig 3.0.5.4p4 (( Happy New Year to all ))
Maybe some files in the jail are corrupted. Try to update it with the jailkut jk_update command: http://olivier.sessink.nl/jailkit/jk_update.8.html The path to the jail is like /var/www/clients/clientX/webX
Thank you Till. jk_update solved. Having added manually php to /usr/bin I also had to force (-f) the copy of php with: /usr/sbin/jk_cp -k -f -j /var/www/clients/clientX/webX /usr/bin/php in order to see it working again.
