@Phil, Screen doesn’t use much bandwidth, I should think it will work fine..give it a go

Does this trick affect bandwidth ? (I sometimes use web-based ssh clients like http://electrica-ms.mures.rdsnet.ro/ but the speed of the connection isn’t the same as with a normal ssh client)

@flakbas – At the moment I use Ubuntu (I did mention that in the post, so it wasn’t such a great guess), but I have experience with Slackware, Redhat and Gentoo. I think you are being a little hard on Ubuntu users in fact you sound pretty distributionist to me:)

The reason I created the method above is so you don’t have any problems with multiple sessions. A simple “ssh server” and then “screen -rd”, Causes a number of errors in different circumstances,
1) If screen isn’t already running you get “There is no screen to be detached.”
2) But more of a serious error for me, If you open a second ssh terminal your the first screen session is detached.

I wasnt claiming to do anything special, I just wanted to make sure when I used screen, it worked everytime without any error messages.

@Yaro – Yeah maybe a little harsh. The “-rd” is to basically reattach a screen session.

@flakbas – That’s a tad harsh, if accurate. Though I don’t even need to put the “-rd” in there. Just “screen” does all I need.

Ubuntu does breed bad Linux habits, just like BASIC breeds bad programming habits.

I’d love for Ubuntu users to just try Arch and actually use Linux for real.

Let me guess, you’re an Ubuntu user? Ubuntu breeds bad Linux usage habits. No offense but you are making this waaaaay to hard. ssh hostname then screen -rd. Congrats on finding out about screen though. It’s good stuff. @Eric – wtf are you talking about password protecting a detached screen. Think about it: you’re trying to password protect a process that belongs to you.

Why do something so complicated? Is it really so hard to just tunnel in and type screen?

Wow you made that pretty difficult! Here’s what I have in my .profile script:

# auto-run screen, but only once
# MUST be done after local .zprofile which usually include PATH munging.
if ps x | grep “SCREEN -S MainScreen” | grep -v grep &> /dev/null
then
echo “Screen is already running.”
else
echo “Starting screen…”
screen -S MainScreen
fi

This way you always log into the remote box the same way, and you can decide after you’re there whether or not you want to use screen. If so, it’s as simple as “screen -x”.

I also have finally worked out a perfect system for automatically re-attaching to ssh-agent forwarding, which was really annoying me before. LMK if you are interested in it.
