************************************
To see default network interface card:
netstat -rn |egrep '(Destination|default)'
To troubleshoot name resolution:
Check the services:
- DNS (bind)
- NIS (yp)
- local (/etc/hosts)
The above list is the default order, but
the default can be overridden by
/etc/irs.conf, which can be overridden by
/etc/netsvc.conf, which can be overridden
by the NSORDER environment variable.
To troubleshoot a server that fails to return a ping:
The server might not be down, but its routing table
might have errors. Someone must walk up to the
server, login, and use netstat to determine whether
the server can see your client's subnet.
To troubleshoot network services:
Check /etc/inetd.conf to determine your service
is not commented out. Also, try HUP'ing the
inetd daemon:
refresh -s inetd
