XDMCP Fatal error for XTRA!X opening display with HPUX11.0

I have been running XTRA!X for NT Version2.0 on my PC and had no problems connecting to my two HP Servers when they were running 10.20. Since I installed 11.0 about 6 months ago, I can not connect to either server. I have no problems connecting to a number of our Sun Servers running 2.7 and 2.8

I get the same error on both HP system H50 and K200 box with 11.00
XDMCP fatal error Session failed 11 failed for display va6its202227.xxxxxxx.com:4
Cannot Open Display.

I have tried it with no other XTRA!X running and while others where active same results each time.

Hi

Maybe name resolution.

nslookup name
nslookup ip

Of the PC and the servers

Does the pc have a similar name to the servers.

The PC has the same name and IP to all the servers. Also there is no firewall between the PC and the servers, all servers that I connect too are on the inside.

sorry to ask the obvious but you do hae a dtlogin process running on the hpux 11 system right ?

other than taht it would most likely be down to hostname resolution .... could you try using a short hostname as opposed to a fully qualified one or try adding the ip address of the pc into /etc/hosts too ?

one other thing I just spotted : va6its202227 is more than 8 characters long which CDE will not like without the following steps :

1. Do this by adding a line in /etc/rc.config.d/netconf such as:

NODENAME="short"

2. You will also need to edit /etc/hosts and add this as an alias
to your hostname. This is very important as CDE will not work
without it. An example entry might be:

123.4.5.6 verylongname short

If you are using DNS and do not wish to have DNS entries for
these "short" nodenames, you must also configure the system
to use /etc/hosts before using DNS to resolve names and IP addresses.
This can be accomplished by using an "/etc/nsswitch.conf" file with
"files" before "dns" and/or "nis" on the hosts
line. An example file that can be used may be found at:

/usr/examples/nsswitch/nssw.filesdns

It can be put into place with:

cp -p /usr/examples/nsswitch/nssw.filedns /etc/nsswitch.conf

3. Finally, change your hostname entries in /var/adm/inetd.sec to your
IP address, for example:

Change line:

dtspc allow 127.0.0.1 verylongname

To read:

dtspc allow 127.0.0.1 123.4.5.6

4. Reboot the machine (/sbin/reboot will do).

Hi

Alex explains what I was after well

If the first part of the names is the same
in the PC and server you have had it.

Do what he asks

I do have dtlogin running.

You might have misunderstood me, plus I have trouble explaining things also.

The 2 HP Hosts are Aspen and Cancun, the va61ts202061 is the PC running NT and EXTRA!X; like I said earlier, I was running XTRA!X on the PC without problems with 10.20, only since I did the cold install of 11.00 is when the problem started, connecting the Sun Solaris box's is no problem. Is there a set up or a configuration that I need to do or load on the HP systems.
