Hi John, > Yeah, I've used it for that, but a question came up at work the other > day - can this be done between different user accounts? Yes, screen(1) has a multiuser mode and access control lists. See the "multiuser" and "addacl" commands. But it needs screen to be setuid root in order to access the other user's named pipe under /var/run/screen/S-$user, and it isn't on this Ubuntu. Creating a hard-link to user foo's pipe in the S-bar directory and opening up the permissions doesn't work; presumably screen vets the user when scanning the directory.

This week it's GNU screen: http://www.gnu.org/s/screen/ Although I haven't really used it, you could also look at tmux which is a more modern utility that does much the same. I think the main selling point of tmux is that it's much, much easier to configure. screen is pretty gnarly, but then again byobu makes it cuddly enough that I've never felt the need. Really useful console window manager, particularly useful for having multiple terminals open on a remote machine, especially as if you lose connection, you can reattach exactly where you left off. Or set a long process running at work, log out and reattach at home. More info at http://www.debian-administration.org/articles/34 http://www.kuro5hin.org/story/2004/3/9/16838/14935 I felt embarrassed when, having used screen for years, I discovered features I'd never known about. For example, it can be a pretty passable serial terminal program. You can also share a screen session from two places (screen -x). You can fit the session to the active window with C-A F. It also has the ability to do split windows. There's probably more I've yet to find too!

This week it's GNU screen: > I too felt a bit silly about not having come across it before I did - and at first I thought "what's the point?" - nowadays it (and emacs) are the first things I install onto a bare new remote machine. I find it particularly handy for watching/working on a number of different cloud servers - they are running Ubuntu so I put the byobu variant on them, with the same setup and set of default 'windows' on each (a shell, a htop, a mutt, an emacs...) and style each one to have a different background colour on the botom status line ;-) > > Yes, very handy.

Dates back to the 80s. :) There's also byobu which is an "enhancement" to screen and can display configurable data. Probably more useful if you're logging into machines where you want to observe the performance. https://launchpad.net/byobu Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday 2011-12-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
