Any way to disable the escape sequence with "screen"?

Hello,

Is there any way to disable the escape sequence in screen, so the user can't escape and run commands?

we have a program that runs under user "shop". We want to wrap it in a screen session, and use .screenrc to set it multiuser and allow the "dev" user to connect to it. Then, if the "shop" user loses his connection, the session will stay running, and then the "dev" user can attach to the session and end it.

We want the "shop" user to be unable to enter any "screen" commands.

Is this possible?

Thanks!

You may be able to use aclchg to restrict the commands certain users can run, pls see the screen man page for details

cheers

Thanks, I was able to do it by placing the commands in the shop user's .screenrc, so that the multiuser access was granted, before revoking access to all commands:

Code:

multiuser on
acladd dev 
aclchg shop -x+r+w "#?"
