CDE and X-Win32 on pc

[Wendy_4]

Hi,

I have a HP C3700(HP-UX 11i), the CDE works fine on the terminal which connected to the workstation. However, when I use X-Window application X-Win32 on pc to connect to the machine, I got a black screen first, then immediately the screen disappeared, the login window can not show up.

What's the problem and how to solve it please?

Thanks,
Wendy

Hi,
I think you must do the following testing:
The Transport Level Loopback Test can be implemented using Internet Services. In this case, you use telnet and ftp to systematically focus on a problem.

# netstat -na|grep -e 21 -e 23
Note: ftp=port 21
telnet=port 23

tcp 0 0 *.21 *.* LISTEN
tcp 0 0 *.23 *.* LISTEN
If LISTEN is the output means your ftp and telnet active.

if you want to start connection logging, run the following command:

#/usr/sbin/inetd -l

See the output in /var/adm/syslog/syslog.log

A.Execute: telnet to remote host. Try to establish a telnet connection to the remote host.
B.Successful? If your telnet attempt was successful, stop. The connection is okay through the Transport Layer (OSI Layer 4).
C.Execute: ftp to remote host. Unlike telnet, ftp does not go through a pseudo-terminal driver (pty) on your system. This step tests to see if the pty is why telnet failed.
D.Successful? If ftp is successful, you likely have a problem with a pty on your system. Contact your HP representative.
E.TCP configured on local or remote host? Neither telnet or ftp will work if TCP is not configured on either side of the connection. Check the /etc/protocols file on both hosts to be sure TCP is installed and configured.
F.Configure TCP. If necessary, install TCP on either or both hosts.
G.Network congested? If TCP is installed on both hosts, do a file transfer to another remote host on the network. Use netstat to check for lost packets.

If 10 percent or more packets are lost, the network is extremely busy. If you cannot determine the cause, contact your HP representative for help.

If both ftp and telnet fail, the /etc/inetd.conf file may be configured incorrectly or the inetd daemon may not be running on the remote system.

Check whether this host is allowed to connect to the display by 'xhost' . If it is not permitted try 'xhost +ip' , replace ip with the ip of the machine from which u want to connect and try again . Also check whether the udp port 177 is listening in ur server which is used for the xdmcp protocol for accepting connection requests 'netstat -an |grep 177'

One simply option,

Before starting the X window just check which Desktop environment its connecting to.

There is an option in it. May be by default its using an another one.

Hi,

This looks like incompatiblity issue with your X-Window application running on PC.
Verify and tune the X-windows properties like fonts, color, display etc

In my earlier project faced a similar kind problem. Reflection-X 8.00 was displaying hazy fonts, strange colors in X Motif applicationm graphs.
When I tune the RX propertis (color,Window Manager) problem resolved.

Hi all,

Thanks for your help!

FTP and telnet are working fine. On the PC side, I have no problem to connect with several machine with VUE and CDE environment, but only this one has problem.

I need further help.

Thanks,

Hi,

Check if name resolution at WS is consistent with name resolution in PC.

Check if when logged at the WS you can ping the PC and if the PC can ping WS.

Enjoy :

Hi Pedro,

I can use nslookup on WS to see my pc and use ping on pc to see my WS.

Any otherthing I need to do?

Thanks,
Wendy

Hi,

Check if name resolution and reverse name resolution are consistent:

#nslookup WS
#nslookup ip.adresss.ws must return the WS name, the same on PC.

Hi Pedro,

nslookup has no problem. it seems not the cause here.

Thanks,
