It is the NIC card and the TCP protocol stack that are bothering watchdog. I know enough red hat to know I do not know how to diagnose and then remedy the problem.

Start with connectivity: ports, ethernet cables, maybe the NIC card.

If that does not help then assume you misconfigured TCP - start with man ifconfig. I assume since everyone uses that, Red Hat does, too.

GETTABLE(8)						      System Manager's Manual						       GETTABLE(8)

NAME
gettable - get NIC format host tables from a host SYNOPSIS
/usr/sbin/gettable [ -v ] host [ outfile ] DESCRIPTION
Gettable is a simple program used to obtain the NIC standard host tables from a ``nicname'' server. The indicated host is queried for the tables. The tables, if retrieved, are placed in the file outfile or by default, hosts.txt. The -v option will get just the version number instead of the complete host table and put the output in the file outfile or by default, hosts.ver. Gettable operates by opening a TCP connection to the port indicated in the service specification for ``nicname''. A request is then made for ``ALL'' names and the resultant information is placed in the output file. Gettable is best used in conjunction with the htable(8) program which converts the NIC standard file format to that used by the network library lookup routines. SEE ALSO
intro(3N), htable(8), named(8) BUGS
If the name-domain system provided network name mapping well as host name mapping, gettable would no longer be needed. 4.2 Berkeley Distribution November 17, 1996 GETTABLE(8)
