XDMCP problem

XDMCP problem

I get the login windows, but after that, the Copyright window appears and stays indefinitely. No further window appears.

I have checked the following:
* No errors at all in Xerrors
* No errors in startlog. Last line shows: "not sourcing //.profile (see //.dtprofile)"
* DNS resolution works ok
* dr_dt does not show significant problems
* /etc/securetty
* /inetd.sec
* Other machines in the same netowrk work
* All users in the system show the same problem
* I have tried three different X-Windows software.
* X programs launched from a telnet window(i.e. xclock

Re: XDMCP problem

Hi,

- look for errorlogs in ~/.dt
- enable session logging in ~/.dtprofile (a description is found in this file)
- look into this new session log

Re: XDMCP problem

Qu : All users including root ?

Qu : Is NIS or NFS mounted $HOME dirs involved.

Qu : Can users login via telnet, rlogin OK ? I guess yes re test Xclock above right ?

Qu : Has this always happened ?

Qu : CDE Front-panel -> options-> failsafe session : does this work ?

Do any of the X windows clients contin any clues ... most have a log or debug facility

What happens if you launch xclock -display :0

checked permissions / ownership on /tmp ?

/var not full ?
anything in syslog.log at time of attempted logins

Could contents of .profile be causing this ?

Re: XDMCP problem

Hi:

Thanks for the clues, but could not get the XDMCP direct working yet.

look for errorlogs in ~/.dt: no errors

enable session logging in ~/.dtprofile (a description is found in this file): nothing there either after logging

Qu : All users including root ?: Yes

Qu : Is NIS or NFS mounted $HOME dirs involved: nothing exported or shared

Qu : Can users login via telnet, rlogin OK ? I guess yes re test Xclock above right ?: that's right

Qu : Has this always happened ?: haven't tried lately; perhaps never worked

Qu : CDE Front-panel -> options-> failsafe session : does this work ?: it works, but a terminal is opened, not a CDE environment.

Do any of the X windows clients contin any clues ... most have a log or debug facility: tried on Netmanage emulation, but nothing on the trace after halting on the copyright window. before that, only could see messages about confirmation of fonts and color options, no evident errors.

What happens if you launch xclock -display :0. It works.

checked permissions / ownership on /tmp ?: 777

/var not full ?: nope

anything in syslog.log at time of attempted logins: nope

Could contents of .profile be causing this?: profile copied from other servers which do work, so it should not be the problem.

Re: XDMCP problem

If the fail safe sessions works it might imply somehow hostname / DISPLAY is somehow now being resolved correctly ... are you using DNS ? if yes ->

eand use files only (via /etc/nsswitch.conf) , bounce CDE are things any better ?

Can same PC connect to the other servers, if yes are other server on same subnet as faulty server.

Would you be able to run set_parms hostname (i think) check man page to reset hostname.

other thoughts somehow xauth is involved or possibly fonts.

ps -ef | xfs : on working and bad server ?

could also try adding set -x in .dtprofile then attempt a login and then view start.log under $HOME/.dt/

Re: XDMCP problem

I changed to files only, but no improvement.

The PC can connect to other servers on the same subnet.

"set_parms hostname" works.

fonts server works and don't know what to check about xauth.

Debugging in .dtprofile shows equivalent startlog on working and not working server. No output in sessionlogs on either server.

Any other ideas?
