The aLIGO EPICS log (conlog) for the 40m is 'working' at:
http://192.168.113.209/conlog/conlog.php

The process runs inside of GNU screen on megatron.  It relies on `mysql` and `apache2`.

It is started by [[http://upstart.ubuntu.com/|upstart]], which is the Ubuntu init system.  The main configuration script is:
{{{
/etc/init/conlog.conf
}}}
You can start/stop the process using the upstart utilites:
{{{
$ sudo start conlog
$ sudo stop conlog
$ status conlog
}}}
There should NOT really be a need to do this, but if you want to attach to the screen session to see what's going on you can do so like this:
{{{
screen -x CONLOG
}}}
If you accidentally kill the process, restart it as described above ("sudo start conlog").

To change the list of channels when the conlog is running, you need to edit the file (s):
{{{
$TARGET/conlog/add_channel_names
$TARGET/conlog/remove_channel_names
}}}
Then use the conlog MEDM screen reload the channel lists:
{{{
$MEDM/MISC/CONLOG.adl
}}}

To change the channels before running the conlog from a blank database, you would edit:
{{{
$TARGET/conlog/use_channel_names 
}}}
(I believe this should be read whenever the conlog is restarted, but I'm only sure it does the first time you start conlog).
