changing IP address problems: need some help?

[EUSEBIUS]

Hi guys.

I have two computers and I want to use one is a desktop which I want to use a server to run large
computations. I justed started using this, and don't have any experience in networking yet.
I usually log on to the desktop from my other computer (which is laptop) using ssh.

I log on to the desktop using its IP address as follows:
ssh -X username@IPaddress
then i add my password.

This works, but the IPaddress changes everyday and I would like to have a more robust
way to do this e.g., using the machine address etc.

I am running fedora 8 on both machines.

I appreciate any help

Set the Desktop to use a static IP on your LAN

Set either a DHCP exclusion range (your desktop's new static ip will be in that range) or a DHCP reservation for your desktop. Either will work - what you use depends on options available in your DHCP server.

Add your desktop's IP to your laptop's /etc/hosts file with an appropriate name.

Now, from laptop, ssh -X <user>@<appropriate name> and enjoy.
