Sure. At your shell prompt, type: man 5 crontab You'll find the man page for the crontab file, which includes multiple examples of cron entries. All of those use the time specification, though, rather than the @reboot keyword. An example using @reboot: @reboot /usr/local/bin/screen -d -m Rtorrent You can edit the crontab for the user with this command at your shell prompt: crontab -u username -e This will dump you into your editor, editing the crontab file for the user username. Type in the crontab entry (for example, the one I used as an example above), save, and try restarting the jail.

Thank you, I googled a bit yesterday actually and now it's working perfectly :) I use linux since 6 years and I've never seen this reboot command actually, but I'm used to cron, but thanks a lot for pointing this out, it's very useful :) Erik -- Wael Nasreddine http://wael.nasreddine.com PGP: 1024D/C8DD18A2 06F6 1622 4BC8 4CEB D724 DE12 5565 3945 C8DD 18A2 /o\ The mark of a good party is that you wake up the next morning wanting to /o\ change your name and start a new life in different city. /o\ -- Vance Bourjaily, Esquire pgpSOWrzq8yz7.pgp Description: PGP signature
Screen inside Jails + su
Hello, I have a FreeBSD server which is Jails based, I have created a special jail to run 3 rTorrent process for 3 users, I made all the permissions and added the users, then I launched manually (for testing purpose) these screen sessions for the 3 users using the below method: - jexec onto the jail. - su to the user: su -l wael - run a detached screen: screen -dmS Rtorrent I have a .screenrc for each user in place to run one command, rtorrent Now I have 2 questions: 1) How can I add this procedure to the jail startup?? 2) I can't attach the screen, everytime I try to I get an error: # su -l wael % screen -Dr Rtorrent Cannot open your terminal '/dev/ttyp6' - please check. What's going on? why can't I attach the screen session ?? Thanks :) -- Wael Nasreddine http://wael.nasreddine.com PGP: 1024D/C8DD18A2 06F6 1622 4BC8 4CEB D724 DE12 5565 3945 C8DD 18A2 /o\ I had a friend who was ready for a memory upgrade on his Mac notebook, and he /o\ wanted to know how much megaram he needed. pgp42A1CxBSNK.pgp Description: PGP signature

If you have used jexec to get into the jail, then you won't have a pty within the jail, and anything which relies on one will fail to execute. Start up sshd in the jail, then ssh to it and see if you can attach the screen.
