If you like to install and update Webmin via APT, edit the /etc/apt/sources.list file on your system and add the line : deb http://download.webmin.com/download/repository sarge contrib You should also fetch and install my GPG key with which the repository is signed, with the commands : cd /root

wget http://www.webmin.com/jcameron-key.asc

apt-key add jcameron-key.asc You will now be able to install with the commands : apt-get update

apt-get install webmin All dependencies should be resolved automatically.

To change the SSH port number login as root, and edit /etc/ssh/sshd_config

Find the line that says Port 22 and change 22 to any number between 1024->65535 (above 30000 is best) and save the file.

Once done, run:

/etc/init.d/sshd restart

Now start a new SSH session (don’t close your existing one), to make sure that you can get in.

apt-get install sg3-utils
/usr/bin/sg_start --stop /dev/sda

ln - make symbolic links

A symbolic link is a "file" pointing to another file.

To make a symbolic link :

ln /original/file /new/link

This makes /original/file and /new/link the same file - edit one and the other will change. The file will not be gone until both /original/file and /new/link are deleted.

You can only do this with files. For folders, you must make a "soft" link.

To make a soft symbolic link :

ln -s /original/file /new/link

Example:

ln -s /usr/local/apache/htdocs /var/www/htdocs

Note that -s makes an "empty" file pointing to the original file/folder. So if you delete the folder a symlink points to, you will be stuck with a dead symlink (just rm it).

The next time you reboot, the initialization scripts will activate it automatically and there's nothing more to be done.

However, if you want to make use of it right away, you'll need to activate it maually. As root, type:
mkswap -f /dev/hda6
swapon /dev/hda6

Swap Files
There might be times when you've run out of swap space and it is not practical to repartition a drive or add a new one. In this case, you can use a regular file in an ordinary partition. All you have to do is create a file of the size you want
dd if=/dev/zero of=/var/my_swap bs=1024 count=131072
and activate it
mkswap -f /var/my_swap
swapon /var/my_swap

This invocation creates a file called my_swap in /var. It is 128 Mb long (128 x 1024 = 131072). Initially, it is filled with zeros. However, mkswap marks it as swap space and swapon tells the kernel to start using it as swap space. When you are done with it,
swapoff /var/my_swap
rm /var/my_swap
