Hi,

have a look at your hostname configuration.
Try a nslookup to 146.216.20.73.
Did you get the hostname ?
If not check /etc/hosts or if you have DNS (server) check the DNS configuration.

Make sure that all X Clients which connect to other devices are correctly defined in DNS, both forward and reverse lookup need to operate properly.

Give that a whirl.

If that doesn't work, I would investigate the level of Netscape you are using. MIT-Cookies are related to Web Browsers.

HTH!

On my XClient nslookup works well.
On my XServer nslookup is not installed, but
I can ping my own IP-adress.
The /etc/hosts looks good, I can see
127.0.0.1 localhost and
the correct IP and Hostname.

Karfich,

You should install BIND (which includes DNS and nslookup) on the XServer. It is recommended.

Since your Clients are able to perform nslookups, so should your Server. This will also maintain a constant information source for IP Addresses and Hostnames.

This should be performed before attempting any further diagnostics.

Hello Albert,
I am not using Netscape at all, it is even not installed. But I wondered also about the MAGIC COOKIE Authentification message.
Perhaps I have to force the system to make theauthentification with xhost ? (how can I do this ?)
Ciao

Ok I will install BIND and tell you the result.
Thanks to all for your fast response.

Ciao Natascha

Good Point regarding the Cookie.

Xhost, XServer, XClient security has developed and evloved arount the IP Address/FQDNS name.

Installing DNS should relieve your problem. The mere fact that the Clients use DNS and the Server does not is an issue, and possible source of the MIT-COOKIE (which come to think of it is an X Windows issue, not Http).

Hope that helps.
