CDE Remote login

Marius Pana_1 — Tue, 16 May 2006 07:36:51 GMT

Hi all,

I have 6 rx1620 servers running hp-ux 11i and I am unable to log-in remotely on any of them.

None of them have video cards so I cannot test it locally but dtlogin starts as well as xfs.

Networking is configured and dns is working correctly. I am not getting any output in any logfiles when I try to connect (syslog.log, Xstartup.0.log or Xerrors).

I have no idea where else to check. Any help will be greatly appreciated.

Many thanks!

Hi,
there is a firewall?
If the answer is yes you need to open the port for the X communication.

There is no firewall between us. Very strange indeed!

You running through an X emulator?
If so, have you doubled checked the config in there?

If not, how are you connecting to the system?

I have tried from a linux box (gentoo xorg 6.8) to connect via Xnest and X and windows running cygwin.

I have a couple of other servers (rp3440) that Ican connect without any problems. The only difference being that the rp's have vga cards while the rx's dont.

dr_dt on one of the servers does give an error:

ERROR: HP CDE will not work properly if the hostname is greater than 8 characters. Yours appears to be 11 characters long.

The others do not have this problem.

Can you get a dtterm/xterm window?

Once you connect to the system,
xhost +
export DISPLAY=

/usr/dt/bin/dtterm
or
/usr/bin/X11/xterm

Do you get a dtterm/xterm window?

Even simplier, can you start the xclock?
What errors are on screen when you try?

I am not connected locally. Locally in my case means via serial console. I have configured networking and am connected via ssh.

I can get all of these via X forwarding through ssh.

# export DISPLAY=99.100.1.179:0

Hi,

xhost + (you need to execute it in your client system)

export DISPLAY=:0.0 (in the server that start the CDE)

Can you ping your client system from the server?

You do not need to be connected locally. If all is well you could start xclock on a server that is some 10000 miles away.

On the system you are presently typing on and logged into, issue the command 'xhost +'

Then you can export DISPLAY

Any errors when doing the xhost + ?

Re: CDE Remote login

xhost + on my local display is set.

# export DISPLAY=99.100.1.171:0.0
# /usr/dt/bin/dtterm
Error: Can't open display: 99.100.1.171:0.0
Error: Couldn't find per display information

The above is the error I get.

I managed to get an xterm, hpterm, sam ,etc to display on my local machine. The problem was that my local xserver was running with the nolisten tcp option.

Now I can export the display on any of the servers and run X programs but I still cannot connect via Xnest or directly with X.

One other thing I noticed is that port 6000 is not listening...if that helps anyone :)

Verify,

# swlist -l product CDE

# Target: node:/
#

CDE B.11.11 HP-UX CDE User Interface

and,

#more /etc/rc.config.d/desktop
# CDE Desktop enabled
# DESKTOP=CDE
# CDE Desktop disable
DESKTOP=NOCDE

and,

# more /sbin/init.d/dtlogin.rc

rgs,

Marius Pana_1 — Wed, 17 May 2006 06:22:20 GMT

ran,

swlist -l product CDE returns:

CDE B.11.23 HP-UX CDE User Interface

and /etc/rc.config.d/desktop looks like:

# CDE Desktop enabled Tue May 16 15:00:36 EETDST 2006
DESKTOP=CDE
DTPRTSVR=
DT_LOCAL_X_START_ALWAYS=

I have tried to changing DESKTOP to NOCDE and still no success.

Thanks.

Is dtlogin processes running? do you see any error message/warning/info in /var/dt/Xerrors? in $HOME/.dt/errorlog?

Re: CDE Remote login

Marius Pana_1 — Wed, 17 May 2006 06:41:37 GMT

dtlogin is running:

ps -ef | grep dtlo
root 2973 2962 0 14:40:08 pts/0 0:00 /usr/dt/bin/dtlogin
root 3340 1441 0 14:41:01 pts/0 0:00 grep dtlo

so is xfs:

ps -ef | grep xfs
root 52 0 0 14:33:17 ? 0:00 vxfsd
root 1360 1 0 14:34:25 ? 0:00 /usr/bin/X11/xfs -config /etc/X11/fs/config -port 7000 -daemon -quiet_if_addrinuse
root 3343 1441 0 14:41:20 pts/0 0:00 grep xfs

no errors whatsoever in /var/dt/Xerrors and the $HOME/.dt.. has not been created since I have not managed to connect remotely.

Thank you!

Marius,

DESKTOP=CDE

is correct.

probe,
# ps -ef|grep dtrc

root 4948 1 0 Feb 11 ? 0:00 /sbin/sh /usr/dt/bin/dtrc

# /sbin/init.d/dtlogin.rc stop
# /sbin/init.d/dtlogin.rc start

Re: CDE Remote login

Marius Pana_1 — Wed, 17 May 2006 06:54:09 GMT

ps -ef | grep dtrc
root 3492 1 0 14:52:30 pts/0 0:00 /sbin/sh /usr/dt/bin/dtrc

I've stopped/started the daemon numerous times. I noticed that sometimes it does not stop it unless I run the command dtlogic.rc stop numerous times. In any case I have stoped and started the daemon. The logs still show nothing.

Thanks.
