Problem with DT Login.

Mani Vannan — Sat, 18 Mar 2006 02:04:36 GMT

Hi everyone,

I've got a problem with one of our Workstations running CDE on HP UX 11.11.

The Workstation, was out of use for more than a month and now only the root user is allowed DT Login & when normal users try for DT access, the screen simply hangs, and the login screen returns to the console after a while.

When I tried changing the UID of an user to "0", and then tried for DT access, it perfectly works fine. I've checked the disk space on the user's home directory, and it's just 60 % full.

Could anyone please guide me as to what could be the possible problem.

Thanks a million.

What does syslog file say?? May be at DT, only root is allowed to login.

Hi Mani,

CDE usage is seems to be restricted only to "root" & uid 0.

Check /etc/dt/config/Xsession.d/*.nologin
& /etc/dt/config/Xstartup files for login restrictions.

Similarly check following logs files
/var/dt/Xerrors
$HOME/.dt/errorlog
$HOME/.dt/startlog

CDE Guide is at

Hi Mani,

Could you post the errors from the file $HOME/.dt/errorlog of one of these users ?

Regards,
Robert-Jan

Hi RAC,

These are the following lines I was able to look in the Sylog file, related to dt.

Mar 17 19:24:37 akinnaa0 inetd[864]: dtspc/tcp: Added service, server /usr/dt/bin/dtspcd

Mar 17 19:24:37 akinnaa0 inetd[864]: rpc.cmsd/udp: Added service, server /usr/dt/bin/rpc.cmsd

Mar 17 19:24:37 akinnaa0 inetd[864]: rpc.ttdbserver/tcp: Added service, server /usr/dt/bin/rpc.ttdbserver

Plus, I got a message like this:

Mar 17 19:27:15 akinnaa0 syslog: libtt[1733]: ttdt_Xt_input_handler(): tttk_mess
age_receive(): TT_ERR_NOMP^INo ttsession process is running, probably because tt
_open() has not been called yet. If this code is returned from tt_open() it mean
s ttsession could not be started, which generally means ToolTalk is not installe
d on this system.

Can you please help me to interpret something possibly wrong ?

Thanks.

Hi Sameer,

I've checkout all the files you've mentioned and found the following in startlog in the users .dt dir, which reads:

Hi,

DT usually is very sensitive to errors in startup files.
Please try to rename temporarily the user's .profile and .kshrc files an try to log in.
Additionally you can remove .dt directory in the users home directory. In 90% of cases this helps.

Hi Mani,

Chech the permissions of the /etc/hosts file

-r--r--r-- 1 bin bin 616 Jul 1 16:03 /etc/hosts

# nslookup hostname
# nslookup ip_of_hostname

the output of both commands should be the same.

Hi,

First check what robert has suggested. Apart from that you need to perform a small test following reasons.

"dtwm: PID 2407: Fri Mar 17 19:58:33 2006
Workspace Manager: Menu specification UserMenu not found
"

The above error points something is missing. Assuming that there are some config files missing for already existing normal user, we might have to confirm for new users.

create a test user and test his DT.that is...

useradd -m test
passwd test

By this I'm just eliminating a possibilty of config file missing/corruption issue. By creating new user, a .dt dir will be created under his home dir, with the available config templates which is in /usr and /etc dir. If the DT works for this new user, then we might have to think of a workaround of purging the DT's of existing normal users and fixing it with right ones.

If only root can login also check permissions and ownernship of /tmp.

consider running dr_dt and examining the output, and perhaps comments on what levels of CDE customisation on a per user basis and in terms of in-house cleanup routines might be of use here.

Mani Vannan — Mon, 20 Mar 2006 00:13:48 GMT

Hi all,

Per Robert's Suggestion, I've checked out the file permissions, and is set to 0444. Further, the nslookup command displays the same output for both the ip and the hostname.

Senthil,

I tried creating a new user (test) and tried DT access thro' the new Id, but it didn't work. Also, even after all the Processes of the user (test) had been killed, the user is still listed in w -s. There are no processes of the user test displayed when ps -ef | grep is issued, but I'm unable to even start a remote Xsession.

Can you please help me trouble shoot this ?

Thanks.

Mani,

Best regards,

Re: Problem with DT Login.

Mani Vannan — Mon, 20 Mar 2006 06:29:10 GMT

Hi Robert,

I ran the dr_dt found under /usr/contrib/bin/X11 and found a few discrpancies and corrected them, but still I recieve the following error & I'm attaching the error screenshot herewith.

The dr_dt output had 0 errors and 11 warnings, & i've corrected all of them.

Please help me to fix this,

Thanks a lot.

Mani,

Are your users sharing one homedirectory ? What kind of shell are they using ?

Robert-Jan

Re: Problem with DT Login.

Mani Vannan — Mon, 20 Mar 2006 07:27:14 GMT

Hi Robert,

All the users, share a common home directory, except the root and the startup shell would be /usr/bin/sh.

(the lv containing the /home dir is just 60% full). I even tried creating a new user with a different home dir and that too fails.

Would be glad to provide any further info which you want.

Thank you very much.

Robert-Jan Goossens_1 — Mon, 20 Mar 2006 07:32:17 GMT

Hi,

I don't think sharing one homedirectory is supported for CDE. Try to create a user with a different local homedirectory, and try try to start CDE again.

Hi Robert,

Than you for the info !

I tried creating a new user, with a different home directory, and now the CDE login works, but takes yeons to log in. Plus I got this error,
_____________________________________________

But still, the root login works perfectly fine. Can you please advise me on this.

Thank you very much.
