How to check and stop if DDoS attack is going on.
Sep 20th
Distributed denial-of-service attacks
In a distributed attack, the attacking computers are often personal computers
with broadband connections to the Internet that have been compromised by viruses
or Trojan horse programs. These allow the perpetrator to remotely control machines
to direct the attack, and such an array of computers is called a botnet. With
enough such slave or zombie hosts, the services of even the largest and most well-connected
websites can be disrupted.

cPanel – Manually back up and transfer an account via SSH
Jun 22nd
Sometime accounts are to big to transfer via the WHM transfer feature.
Below you can find some steps to do so manually
Log into your server and create a cPanel backup for the account
/scripts/pkgacct <username> <location> backup
<username> refers to the username you want to backup.
<location> is the path to where the backup will be placed (in your case you want to put /backup/cpbackup here).
So backup tells pkgacct that you want to create a backup file.
If you leave this off it creates a cpmove archive. Not sure what the difference is between a cpmove and a backup file, but this tells pkgacct you just want to create a <username>.tar.gz file in <location>.
And after the backup has been completed you can simple move it by pushing it via SCP

Problems with CenotOS5 – cPanel and BIND
Jun 22nd
If you have issues with cPanel running CentOS5 with BIND then the easiest way is to downgrade BIND to 9.2.4
The reason you’re having trouble is because CentOS 5 uses bind-9.3 and CentOS 4 uses bind-9.2 – The changes between these versions is significant enough that cPanel won’t work with it properly.
For instance by default there is no /etc/named.conf file created when bind-9.3 is installed and the default named.conf file for bind-9.3 is significantly different than in older versions.
Until the code is updated to work with bind-9.3, I have found the workaround to be to remove bind-9.3 packages and install bind-9.2 packages as follows:
kernel yum upgrade
