> ping never does a reverse lookup.
Yeah, but ping works *both* ways, which means that B can
happily enough when it's pinging, but can't resolve it when A
trying to connect to B and B's trying to lookup the connecting
machine. Most odd.
ping only ever does forward lookups, ie name->ip. AFAIK it never
reverse lookups, give it an ip address, and it won't look up the name.
rshd on the other hand will know the ip address of the incoming
connection, and will try to resolve the ip addr to a name. which is
probably causing niall's problemo.
best thing to do is probably to to install a local name server, to take
care of local lookups, and cache other lookups.
