Another possibility is that the connection request is being dropped on
the floor by kernel packet filtering. The default filtering in RH 7.2
is pretty aggressive (just the other day I had to change quite a few
things to get it to allow incoming and outgoing NFS, for example).
Check your ipchains setup in /etc/sysconfig/ipchains.
IIRC, the default ipchains setup does *not* filter localhost
connections, but I think it would apply to connections showing a source
address of your Ethernet IP.
