9.5 Network Problems
Many problems of your system may be network-related, even though they do not seem
to be at first. For example, the reason for a system not allowing users to log in might
be a network problem of some kind. This section introduces a simple check list you
can apply to identify the cause of any network problem encountered.
When checking the network connection of your machine, proceed as follows:
1 If using an ethernet connection, check the hardware first. Make sure that your
network cable is properly plugged into your computer. The control lights next
to your ethernet connector, if available, should both be active.
If the connection fails, check whether your network cable works with another
machine. If it does, your network card causes the failure. If hubs or switches are
included in your network setup, suspect them to be the culprits as well.
2 If using a wireless connection, check whether the wireless link can be established
by other machines. If this is not the case, contact the wireless network's administrator.
3 Once you have checked your basic network connectivity, try to find out which
service is not responding.
Gather the address information of all network servers needed in your setup. Either
look them up in the appropriate YaST module or ask your system administrator.
The following list gives some of the typical network servers involved in a setup
together with the symptoms of an outage.
DNS (Name Service)
A broken or malfunctioning name service affects the network's functioning
in many ways. If the local machine relies on any network servers for authentication
and these servers cannot be found due to name resolution issues,
