Trivial ScriptsI did a good deed for the day today, I went round and wrote manpages for all the random scripts and programs I've put together, and installed upon the machines I maintain.
Most of these are very trivial, for example a script which is called hourly via a crontab called 'checkDiskSpace'. (See if you can guess what it does!)
This is something that I've been meaning to do for a while, partly to help any successor who might inherit the machines (hopefully in the distant future), and partly to make it obvious that I'm caring about the state of "my" machines
Talking of trivial scripts, I put together a simple script, locations, to report on where users login to machines from - this is quite interesting.
I added it to the crontab for our VPN server, and now if a user connects from more than five distinct machines a month I'll get an email. Likely it will be a false alarm, but it could be indicative of an account compromise.
To continue my good work this has a manpage, and a Debian package!
