Using grub2 we can directly boot an (iso9660) ISO using its loopback option. It provides another nice rescue method – for example when using grml (the Debian based Linux Live-CD for sysadmins. We no longer need to extract kernel and initrd from the ISO to be able to boot it using the isofrom bootoption. So we need to do is put a plain grml ISO to our harddisk.
If we are using grub2 already consider adding an entry like the following to our grub config

To use SSH keys instead of plain password to login:
1. Logon to WHM and go to Main >> Security >> Security Center
2. Under "SSH Password Auth Tweak" and disable the Password Authentication.
3. Under "Manage SSH Keys" click on Generate new key.
4. Give a Key name and Generate a good password (remember it). Choose KeyType as DSA since it’s more secure than RSA.

Do the following:

1. Upgrade the kernel. The one you are running is slow, has bugs and has security vulnerabilities

2. Make sure you are an up to date compilation of httpd and php (i.e. rebuild it through WHM).

3. Check in WHM > Apache Status to see what the children hogging resources are doing

Public-key authentication is is based on the use of digital signatures. Each users have to create a pair of keys. ie public key and private key. Private key is owned by user and the public key is given to the server. When the user tries to authenticate, server check for the matching public key and sends a challenge to the user. Private key is used to authenticate the user, so never provide your private keys to others. If anyone got your private key, they can login to the server as you. So keep your private key file in a secure place and make sure that no one else has access to it.

Secure Shell (SSH) public key authentication is used for clients to acess servers without using passwords.

Steps to configure public key.

OpenSSH is the SSH software installed on the client system. The ssh -V will show the openssh details in the server. (more…)
