How to Start
 

In my computer lab there are 11 systems. All have linux installed on it. Some are Debian based and others are Red Hat based. We were thinking of networking these machines, so that we can share the whole data. But we dont know how to start. All the systems are connected to Server vis LAN.
Is any additional softwares necessory?

as you wrote in your post that you have connected your machines through LAN with your servers. it means you have some server. if yes then you can share the data from your server to your machines. if there is no server or you don't need it then you could try NFS.

Networking
 

we dont have any access to the server. so we will need an alternative.
what is NFS. can you please explain me.
thank you for your reply...

I am trying to do the same with some old computers that I got here and there. I wanted to connect them together to have more number crunching power.

To do this, you will need a bit of time to read and understand some basics about networking. I would suggest looking around the web for "multihost tasking" and "linux cluster". You should find enough on the web to help you get started.

NFS stands for "Network File System" and is the native Linux way of sharing directories over a network. Search Google for NFS Howto, and then come back and ask some more questions.

Basically, you set up a directory on one machine and allow it to be accessed by other machines.
