SSH Sudden Death Based Clustering System

To all,

Hi.

I Use Fedora, The Kernel Version is 2.6.11.5

(uname -a => Linux 2.6.11.5 #1 Sun Apr 3 05:13:04 KST 2005 i686 i686 i386 GNU/Linux)

I have 4 Computers, The one is Gateway which is working to distribute

to node by LC Algorithm and The other Computers are node.

The Loabalancing is working fine( I try to connect on SSH using

program to gateway, it works fine).

But There is a Problem. If I do not anything working about 10 minutes

(or 20 minutes) on SSH Connection 22 port, The Connection

is Closed automatically.

I don't know the reasons.......

I assume that .. The Gateway Distribute Connection..

I mean that I connected one node and I do not working

on SSH connection about 20minutes, and I try to working

something continueing, then Gateway makes connection

the other node, I think..

anyone who know How to solve this problem?

If you know how to treat it and teaching me... I will appreciate.

Thanks to read...
