# On the machine which will run screen
sudo chmod u+s /usr/bin/screen

If logging in as different users (e.g. chrisroos and jamesmead)

# The 'server'
screen -S <session_name>

# No need for next 2 commands if using sample ~/.screenrc file below
ctrl-A :multiuser on
ctrl-A :acladd <client_username>

# The 'client'
screen -x <server_username>/<session_name>

If logging in as the same user (e.g. both developmentserver)

# The 'server'
screen -S <session_name>

# The 'client'
screen -x <session_name>

Here’s a sample ~/.screenrc file

shell -/bin/bash # load your .profile properly
multiuser on     # allow other users to connect
acladd chrisroos,jamesmead,lukeredpath,bensales,paulbattley,louisgarman,joelgluth,jamesadam,tomlea,craigsmith

# Skip the pointless startup message

# Call shells 'shell' in the bar at the bottom
shelltitle "shell"

# Don't say 'Wuff Wuff' every time the process beeps
bell_msg ""

# Change default scrollback value for new windows
defscrollback 10000  # default: 100

# F5/F6 to resize the current split region
bindkey -k k5 resize -1
bindkey -k k6 resize +1

# F7/F8 to move between screens

# When split, show what each region is
caption splitonly "%(malformed snip inclusion: {.c}) %n%f %t"

# Show a list of window titles at the bottom of the screen
