--ve a server that supplies NIS as well as NFS service to 50+ clients. We would like to construct a backup machine that if the primary server went down would continue to provide NIS and NFS service if the primary server went down. This might be two different machines. We know about NIS slave servers. Could anyone point me to a reference of somewhere were this problem of running a backup server has been addressed and solved? There must be a simple solution but those I come up with don't satisfy me. One problem that faces us is that our user directory partition is large and not quickly copied. ======================================================================= QOTD: "Do you smell something burning or is it me?" -- Joan of Arc ------------------------------------------- Aaron Konstam Computer Science Trinity University telephone: (210)-999-7484
