/etc/hosts - How to alias IP's

Whenever you ssh or scp the syntax is usually:

> ssh myname@129.25.8.219

But remembering an IP address is hard if not impossible. There is a file in every Unix environment called "/etc/hosts" (the file is "hosts" in the root directory "/etc"). If the file has a line like:

129.25.8.219 newton

then the syntax for the ssh command is simply:

> ssh myname@newton

How to fake "/etc/hosts"

The file "/etc/hosts" is a system file and as such needs root to edit it. If you are not the computer administrator you need to create a local copy. The commands:

> cd ~
> mkdir etc
> emacs etc/hosts

Will open an editor to the local hosts file. Enter the lines as above:

129.25.8.219 newton

... save and exit emacs. Now to register the new hosts file:

> emacs ~/.bashrc

and add the following line:

> export HOSTFILE="~/etc/hosts"

Re-source your .bashrc file with

> source ~/.bashrc

and you should be able to use the alias power of the hosts file.
