The worst login file I have ever seen...
View login.bat
This is the worst login file I have ever seen.
I redacted a few things with '---' to protect the identity of the MCP who created it, and the idiots who kept updating it, and the unfortunate client who just ditched them because nothing ever worked right...
REM @echo off
REM universal login batch file
REM Put individual user settings below in the user section.
REM Modified by --- on 5/21/03 for new server
REM Modified by --- on 11/11/03 (added check for term server)
REM Modified by --- on 9/9/008 to reflect fact that server2 is now ntserver.

Please ignore the horrible DB schema. It's not mine. It's an introspection of a horrible Windows ticket app.
I upgraded from Django 1.8.x to 1.9 and the following query that I use when gathering stats (Top ticket creators) broke:
>>> Company.objects.all().annotate(ticketcount=Count('srservice'))
Traceback (most recent call last):
File "<console>", line 1, in <module>

Restore cryptolocker encrypted files if you have ZFS
View gist:30da06041cd339eecbb2
# If you have a box running ZFS serving your Windows file shares, and someone gets hit with CryptoLocker, here's an easy way to restore individually encrypted files.
# Assuming your infected dataset is named 'tank/officeshare'
# Find a snapshot of your data before cryptolocker infected it and clone it (something like zfs clone tank/officeshare@good tank/officesharegood
# Find a snapshot of your data after cryptolocker infected everything, but *after* the infected machines were removed from the network and clone it (something like zfs clone tank/officeshare@bad tank/officesharebad)
#Go into the tank/officesharebad directory and run the following command to scan through the bad clone for the 'DECRYPT_INSTRUCTION.TXT' file left behind by cryptolocker, gather 'bad' directories, then grab all the files from them to restore to the current 'officeshare'.
#This command works on FreeNAS or BSD-ish boxes
find . -type f -name 'DECRYPT_INSTRUCTION.TXT' | sed 's/\/DECRYPT_INSTRUCTION.TXT//' | sed 's/^\.\///' | grep -v
