[Linux-cluster] Diagnostics?

[Pool, LC, Mr <14117614@sun.ac.za>]

Hi....


I have 10 nodes that are not connected to any monitor or cd/dvd rom drive or a floppy drive, and I would like to run some diagnostics, like memtest, etc.

Is there anyway that I can do this?

I'm looking at using tftp/bootp, but this would mean writing my own image so as to get the output from the tests to determine if a machine is faulty or not. This would require alot of my time. Is there any free software that is already doing this.?

I'm looking on the web, but most of them are for single pc's....

Any ideas?

Yes.
