IMPORTANT
The debugging procedure described below only applies to a simple net-
work server/client setup that does not involve any internal routing. It
assumes both server and client are members of the same subnet without
the need for additional routing.
a Use ping hostname (replace hostname with the hostname of the
server) to check whether each one of them is up and responding to the net-
work. If this command is successful, it tells you that the host you were
looking for is up and running and that the name service for your network is
configured correctly.
If ping fails with destination host unreachable, either your
system or the desired server is not properly configured or down. Check
whether your system is reachable by running ping your_hostname
from another machine. If you can reach your machine from another machine,
it is the server that is not running at all or not configured correctly.
If ping fails with unknown host, the name service is not configured
correctly or the hostname used was incorrect. Use ping -n ipaddress
to try to connect to this host without name service. If this is successful,
check the spelling of the hostname and for a misconfigured name service
in your network. For further checks on this matter, refer to
(page 937). If ping still fails, either your network card is not configured
correctly or your network hardware is faulty. Refer to
for information about this.
b Use host hostname to check whether the hostname of the server you
are trying to connect to is properly translated into an IP address and vice
versa. If this command returns the IP address of this host, the name service
is up and running. If the host command fails, check all network configura-
tion files relating to name and address resolution on your host:
/etc/resolv.conf
This file is used to keep track of the name server and domain you are
currently using. It can be modified manually or automatically adjusted
by YaST or DHCP. Automatic adjustment is preferable. However, make
sure that this file has the following structure and all network addresses
and domain names are correct:
