CDE startup problem

David Mores — Thu, 15 Jul 2004 10:28:42 GMT

A C3600 workstation running 11.11 was previously working fine. However, recently console logins fail for everyone except root. The user startlog shows a permission problem as follows:

--- Tue Jul 13 15:19:35 EDT 2004

I have looked through the system directories /usr, /dev, /adm with no success. Any ideas for how to better track this problem down would be appreciated.

Thanks,
Dave

swap, and kernel settings for maxtsiz_64bit and maxdsiz_64bit look OK.

What are the perms on /usr/lib/dldl.sl. Also compare it's size to the dld.sl on other system.

Dave, pardon if I am not fully understanding your problem.

/usr/lib/dld.sl: Call to mmap() failed - TEXT /usr/lib/libcl.2
/usr/lib/dld.sl: Permission denied
StartFirst[6]: 3686 Abort(coredump)

this may sound like a long shot, but it is not going to hurt to give it a try.

Looks like the process is trying to lock the memory region and by default the normal user belongs to only group CHOWN.

root belongs to all the below mentioned groups. RTPRIO, RTSCHED, MLOCK, CHOWN, LOCKRDONLY, SETRUGID, and SERIALIZE.

# getprivgrp

this will return only CHOWN.

Try adding the MLOCK privileges to the user's group using setprivgrp and then try again.

If it doesnâ t help, then revert it back.

RAC:

The permissions, size and timestamp on /usr/lib/dld.sl are the same as another system that is operating without this problem:

-r-xr-xr-x 1 bin bin 188416 Jul 17 2002 /usr/lib/dld.sl

Sundar:

getprivgrp only returns CHOWN for any user including root on any of our HP systems. I don't think this could be part of the problem. We have never deal with these global privs ever.

Did this get resolved???

Also are there any errors in /var/dt/Xerrors??

Call to mmap() failed makes me think, that it has something to do with maxdsiz and maxtsiz. Not sure.

Try moving .dt directory of user and then logging in.

Post if this gets solved.

But root can login okay.

>Try moving .dt directory of user and then >logging in.

Tried with no change.

Dave,

What about the permissions of this file /usr/lib/libcl.2 ?

did you any new scripts/binary to the directory /usr/dt/config/Xsession.d ?

-- Sundar

Re: CDE startup problem

David Mores — Thu, 15 Jul 2004 16:27:03 GMT

Sundar:

You win this one! Someone changed the permissions on /usr/lib/libcl.2 to 776.

After changing them to 555, console login was successfull.

Thanks!
