All three are on the same sub-network, have identically configured tcpip for nameserver, netmasks, broadcast...etc, but one of the 540s periodically loses its ability to translate names to addresses for ftp and telnet. (ping it can do and "host node" returns numbers which have had to be gotten from the nameserver!). I can fix this by flushing the routing table and restarting routed. I have run telnet with netdata toggled, and get no output (by name - it works by number). I have put the names and addresses of our most frequently accessed machines in /etc/hosts and the behaviour is strange. With a name in /etc/hosts, ftp or telnet will work - but with a terribly long delay, long enough to make most users ^C out of it. However, using the address, the response is virtually immediate. (Is this because it tries to resolve the name first?) Has anyone seen this sort of behaviour before, or can any network gurus point me in any directions?
