New sockets have a sepcific time slot in which they must send a valid login packet before they are kicked out. The message you're seeing is form this. There should be a metching set of messages from node1 saying it is trying to log into node2. (the message might be supressed though. You will probably need to add the LoginLoops to the verbosity setting.) That error message should provide some clues as to why the timeouts are happening. -- Michael Conrad Tadpol Tilstra For some inexplicable reason, you just wish it would rain.
