The minimum firewall ports for a Windows domain controller and linux server
In order for a Linux (client) box to communicate with (and perform NTLM auth) a Windows domain controller through a restrictive firewall you would need the following ports opened at a minimum:
udp 53 tcp/udp 88 tcp/udp 135 tcp 139 tcp 389 tcp 445 tcp/udp 464
Key_Events_On_Hosts - Splunk EventType
Once upon a time Splunk had an “EventType” named “Key_Events_On_Hosts” then one day it disappeared. It used to power some reports that I use. So I had to go find it from a backup. Here is the EventType is all it’s naked glory.
( sourcetype="WinEventLog*" OR sourcetype="XmlWinEventLog*" (Type="*Error*" OR Type="*Fail*" OR EventCode=1074 OR EventCode=19 OR EventCode=20 OR EventCode=21 OR Eventcode=1001) ) OR ( sourcetype="WindowsUpdateLog" (status="installed" OR status="failure" OR status="restart required") )
Generate random password in batch (command prompt)
If you do a lot of scripting then this snippet maybe useful. I use this snippet to change the default password for Splunk Universal Forwarder installations, from the default to random. You don’t actually need to record the password for the forwarder - and it’s easy enough to reset if you do.
@echo off set pass= set s=abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890 set m=0 :loop set /a n=%random% %% 62 call set pass=%pass%%%s:~%n%,1%% set /a m=m+1 if not %m%==32 goto loop: echo %pass%

OpenOffice opening downloaded documents read only
If you are downloading and opening a lot of documents directly from Firefox. Firefox, by default will write them to disk with read only permission, causing OpenOffice to open them read only. This is annoying if you want to make minor modifications before copying and pasting into a report. The solutions is within Firefox. Go to “about:config” and set “browser.helperApps.deleteTempFileOnExit” to false.
