Dedicated communication between master and slave

rani_162 · 09-15-2005, 01:10 AM

I need to have a dedicated communication between a Master and slave PLC, and monitor so that when the master dies, the slave should take over.I have an ethernet connection between the two.
I am using Linux Fedora core 3.Is Netcat preferable as compared to SSH? If so, why?
Or is there any other possible method.
I am a linux newbie.
Thank you
Rani

Dear Rani,
Please explain it more clearely..... Try to use clustering or someting like that... Actually what you are talking about?? any service or the whole server (PC)??
