CDE and Network in conflict

sandro ginnari — Wed, 24 May 2000 06:55:47 GMT

I have a problem with the network and CDE.
When I configure the network the CDE dose not work. If I disconnect the network cde starts working again!
What happened?
In the /var/dt/Xerrors i found this:
host name is not valid setting display:0

Can someone help me?

Looks like your networking isn't setup correctly on this machine.

Check that /etc/hosts is correct (and that the 'hostname' command matches what is in there).

If your using DNS, check that your hostname resolves correctly (and just because your using DNS, /etc/hosts still must be correct for your hostname and localhost).

Please check if you have an ip-address conflict.
check the file /etc/rc.config.d/netconf for the node name and ip-address
run ifconfig
re-run the cde start up program dtlogin start

Hi,

I agree with the above two. Hope this could help you.

While going to CDE HP-UX checks for all networking parameters during which it is finding some problem and comming out.

Check for your /etc/nsswitch.conf which contains the search order.

if you donot have dns the first options should be files

I hvae also had this problem in CDE. It appears to want to do a reverse lookup
on the host name and make sure that it is not being spoofed.
To check the host name use the command : hostname
To check what CDE is getting use the command: nslookup

Any mismatch in your hosts file or DNS could result in the error you saw.

good luck

Yes, I got this kind of problem a lot of time. Just because Xserver can't find the host, if we don't setup the network correctly. My way:
1. Check /etc/hosts or type "hostname" to check your hostname.
2. Make sure your IP is not a duplicate IP on the whole network.
3. Check /etc/resolv.conf, if you have that means you have DNS setting, make sure your /etc/nsswitch.conf setting is correct.
4. use "nslookup", type your hostname, and make sure you can get the correct response.
5. After these, should be fine.
