Hi all, At the moment I have one dhcp server running ISC dhcpd, and its working fine. However I wish to add another in case the main one goes down. Is it as simple as setting it up on another machine with similar config? My worry is that a client will request an address and both server's will respond, potentially causing problems. Is there a master/slave setup I can use? Or shall I simply set up a second one. Cheers, Fred.
