snmpcheck – Backtrack 5 – Information Gathering – Network Analysis – SNMP Analysis – snmpcheck

SNMP can be a hidden gem that seems to be overlooked sometimes during penetration testing. It is really cool the information you can obtain just using snmpwalk from the command line however the information can be lengthy and unless you are an SNMP OID library or feel like googling a bunch of different stuff it really helps to have tools such as snmpcheck available. Below we describe what snmpcheck, which is written in Perl, will accomplish for you and we also provide a couple of examples against Ubuntu and a Cisco router.

Technology Errors

msysgit clone Error – fatal: Cannot update the ref ‘HEAD’

I wanted to start syncing a git project to my Windows XP laptop so I installed msysgit because of the good things I have heard about it. The latest version was 1.6.2 so I figured that was a good place to start. Using a clone command I knew works on Linux since I use it all the time I attempted to clone a git repository from github onto the Windows PC. I ended up receiving the output below which is filled with errors.

Git Version:


  1. git version 1.6.2.msysgit.0.186.gf7512
