I’ve got a couple of Linux machines that are sitting outside of the Sflow ‘zone’ and AS traffic stats go unmeasured. I wanted to get a rough idea on the number of connections per AS number so here’s a little app that parses netstat and sorts AS numbers by number of connection. NOTE1: This won’t […]
There are 3 primary options: 1. Use PAR with PAR::Filter::Obfuscate or PAR::Filter::Crypto 2. Use Filter::Crypto::CryptFile (requires certain modules installed on target system) 3. Encrypt modules with Module::Crypt.

Find all possible root symlinks (leftover from attempted exploits) and save them as a list ‘symlinks.txt’. ls /var/cpanel/users | grep -v “\`\|\.\|cpanel\|root\|mysql\|nobody” | \ while read CPUSER; do find /home/$CPUSER -type l -not \( -lname “/home/$CPUSER/*” \ -o -lname “*rvsitebuilder*” -o -lname “[^/]*” -o -lname “/usr/local/apache/domlogs/*” \ -o -lname “/usr/local/urchin/*” \) ; done \ > […]

It’s a light weight, reliable monitoring replacement for the pile of garbage most RAID vendors include with their cards. Complex excludes and finds can be specified as Perl […]
I just added a 4th monitor to my office PC and finally admitted to needing help with window placement, far beyond Windows 7’s limited snap feature, this tool really gets the job done: http://www.winsplit-revolution.com/ It’s a free, light-weight ‘snap’ on steroids designed specifically for multi-display setups.
Since XenServer 6.1 (XCP 1.6) there is a new feature that allows you to lock VIF to specific MAC and IP addresses. This is nice (and also very buggy!), but it doesn’t provide any security other than keeping VMs from stealing each others IPs. A better solution should allow to (optionally) isolate traffic between groups […]
