Editing Screen (section)

= Screen Organization =

At JohnCompanies, we currently run a main screen with 10 windows, each window having between 2 and 10 (or more) nested windows inside of it.

The main johncompanies server which hosts all the screens is simply nat.johncompanies.com (or 69.55.233.195).  Simply ssh as your user to nat.johncompanies.com, and your home directory will contain the "dr" (or 'hr') script for reattaching.  

The window organization is roughly as follows (the actual way you organize your screens is up to you, this is the organization for the user 'user'):

<pre>
Window 0:
        0 - info@johncompanies.com pine inbox
        1 - support@johncompanies.com pine inbox
        2 - payments@johncompanies.com (or sales@) pine inbox
        3 - linux@johncompanies.com pine inbox

Window 1:
        0 - johncompanies.com root shell, pwd = /usr/local/www/jc_pub/data
        1 - johncompanies.com root shell, mysql
        2 - johncompanies.com root shell, running tail -f /usr/local/www/signup/ipn.log
        3 - johncompanies.com root shell, pwd = /usr/local/www/scripts

        4 - backup2 root shell - spare window for exec quad/safe
</pre>

Window 0 is usually split into 2 panes to allow easy viewing of the 2 support queues. To move between them, ctrl-p, then the tab key. To un-split the panes, ctrl-p then Q. To resplit the screen, ctrl-p , then S

Some of the windows have a nested window of zero with nothing in it ... this is because they are numbered based on machine name ... window 1 is jail1, and so on, but of course you need to have a window 0 ... so it just sits empty.

On the console screen server (sun), we've also fully automated console screen creation on the console server.  Login as console and execute /home/screen/startconsoles
NOTE: *** only execute startconsoles if there are currently no consoles running ***
if you run startconsoles while other consoles are running you'll end up with a big mess.
TODO: update this script

To disconnect from a serial console session, hit CR to get to a blank line (regardless of screen echo) and hit 
~~.
