Remote Collaboration with screen over ssh

Server side

apt-get install openssh-server screen [vim, emacs, nano] # install required tools, choose your text editor of choice.

chmod u+s `which screen` # add suid root bit to screen to allow multi user mode

# Ensure there are users added in the system.

adduser [username]

usermod -a -G [secondary group name] [username] # optional, add user to additional groups

# start screen

screen -aAUS [screen name]

# inside screen (as user 1)

ctrl-a : multiuser on # turn on multiuser mode

ctrl-a : addacl user2[,user3, ...] # authorize user2, user3,... to access this screen.

Client side

apt-get install openssh-client [openssh-server] [vim, emacs, nano] # install required tools, choose your text editor of choice.

ssh user2@server

screen -r user1/[screen name]

Collaborate as needed. There can be more than 1 screen at a time to edit the source code on one and run tests on another.

See http://www.gnu.org/software/screen/manual/screen.html for screen user manual.

See http://askubuntu.com/questions/117487/using-ubuntus-screen-command-to-share-screens for multi user issues you may have.
