I have several machines on my network that provide services of one type or another. I'm trying to configure them to create detached screen sessions at boot time. Let's take a representative example.
I have a cron job setup under my user ID: @reboot /usr/bin/screen -d -m -S pvr I have also used the syntax "@reboot /usr/bin/screen -dmS pvr". Neither of these has worked. I tried creating a bash script: #!/bin/bash # This script starts a detached screen session on boot. su - <my_user> -c "/usr/bin/screen -dmS pvr" Neither of these work despite the fact that when I run the command "/usr/bin/screen -d -m -S pvr" as my user in a konsole window it creates the screen session as expected (note that I can stack those options to -dmS and it makes no difference). I should say that I'm also unable to start that screen session from crontab in Webmin (I assume it uses the run-parts command to do that). I get no error - it just doesn't create the screen session. I set uid root: "chmod a+s /usr/bin/screen" and I have seen references to changed the permissions of /var/run/screen. I have no /var/run/screen. Any wisdom? Thanks. -- Mark Adams
