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 \ > […]
This tool will poll the output of command(s) or URL(s), and send email alerts if the output changes, contains (or not contains) certain text, or becomes unavailable. 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 […]
Since XenServer 6.1 (XCP 1.6) there is a new feature that allows you to lock VIF to specific MAC and IP addresses.

Create the patch: diff -aru file.orig file > file.patch Apply the patch (-b creates a copy of the original with a .orig extension): patch -b file file.patch
Source is now in github, please help me make it better! If you just want a 32-bit binary (to run on Dom0), download it from here instead. With the help of Ben Booth’s Xen::API (Perl module) I put together a VM migration script to export a VM directly to another host with no intermediary file. […]

Sometimes you need to run another service on port 80 or 443, but IIS binds to every IP by default. Here’s the trick to add/remove IP’s from IIS 7.5. It cannot be done by any web GUI. netsh http add iplisten ipaddress=1.2.3.4 netsh http del iplisten ipaddress=2.3.4.5 netsh http show iplisten
Here’s a nice recipe for a RAID10 array comprised of 4x SSD disks. Tested to work on CentOS 6 (RHEL 6). Be sure to add the discard option in fstab for Trim support. zerombr yes bootloader –location=partition –driveorder=sda,sdb,sdc,sdd clearpart –all –initlabel –drives=sda,sdb,sdc,sdd part raid.100000 –size=250 –ondisk=sda part raid.100001 –size=250 –ondisk=sdb part raid.100002 –size=250 –ondisk=sdc part […]
If for some reason Cpanel’s database cache is out of sync and you can’t remove or delete non-existant databases, you can do so manually: Remove orphaned DB entries from: /var/cpanel/databases/dbindex.db Same here: /var/cpanel/databases/<username>.yaml Then execute the following: /usr/local/cpanel/bin/setupdbmap /scripts/update_db_cache
If a perl module is failing harmless tests and refuses to install, you can force it to with this snippet: perl -MCPAN -e “CPAN::Shell->force(qw(install IO::Socket::SSL));”
