GUI login issues over NFS
by Weiner, Michael 01 Feb '12

01 Feb '12

I am at my wits end, googling, trying various things, and nothing seems to really solve my problem, so I thought I would break down and write to the community to see if anyone else has run into the issue and actually solved it. My environment of interest contains a mix of various Fedora and CentOS workstations that all participate in NIS for user authentication which then, upon a successful login, automount an NFS $HOME directory. And here is the rub, I am migrating that NFS back end FROM a Sun X4540 (which has been working flawlessly for the past few years) to an HP X9320 Ibrix system. I replicated my NFS exports from one system to the other, and have tested command line logins over SSH using NIS credentials and that all seems to work quite well. However, whenever a CentOS (or even Fedora for that matter) desktop user tries to log in (either Gnome or KDE) they are unable to successfully log in - and are presented with the nebulous .dmrc error as follows: User's $HOME/.dmrc file is being ignored. This prevents the default session and language from being saved. File should be owned by user and have 644 permissions. User's $HOME directory must be owned by user and not writeable by any other users. Followed promptly by Your session only lasted less than 10 seconds. If you have not logged out yourself this could mean that there is some installation problem or that you may be out of disk space. Try logging in with one of the failsafe sessions to see if you can fix this problem. Now I have, of course, checked the permissions and ownership of the $HOME directory and also the .dmrc file and they are correct - but no matter what I do, this fails. Things I have tried: with NIS turned on, without NIS turned on, using automount, without using automount, using all different kinds of NFS options passed to a local mount of the /ibrix/testing area which I am using to test GUI logins from the local workstation under Gnome or KDE - all to no avail. And of course I have spent countless hours/days googling and have even written to HP for some advice. I am pretty confident that perms/ownerships are correct, but I just cant seem to get anything to work. Has anyone run into a similar problem? Has anyone found a solution? Does anyone have any suggestions that I am not thinking about?

How does a linux DHCP machine inform DNS of its name and obtained address
by Jerry Geis 01 Feb '12

01 Feb '12

I am using a number of DHCP devices on a network. Working fine with CentOS 5 x86_64. My question is now how do I tell the DNS (after I get my DHCP address) about my devices name and IP address so that others can find me by my machine name? I thought that was an automatic thing - but it appears not. Thanks, Jerry

Quantum scalar i40 tape partitions
by Xinhuan Zheng 01 Feb '12

01 Feb '12

Hi All, I have a Quantum scalar i40 tape library. I need to configure it to TWO tape partition libraries, e.g., library_a and library_b, so that each library has its own tape drive. Then connect this physical tape library to two different CentOS servers so that each server can see its own media changer and tape drive. I once had a successful configuration on one host but NOT on the other. One host sees the media changer and one tape drive, while the other host only sees the tape drive. After I delete tape partitions and re-create them both servers are totally screwed up. This is CentOS 5.7 kernel 2.6.18-274. On one server: # cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: HP Model: Ultrium 5-SCSI Rev: Z58Z Type: Sequential-Access ANSI SCSI revision: 06 Host: scsi0 Channel: 00 Id: 00 Lun: 01 Vendor: QUANTUM Model: Scalar i40-i80 Rev: 135G Type: Medium Changer ANSI SCSI revision: 03 # mtx -f /dev/sg0 inquiry mtx: Request Sense: Long Report=yes mtx: Request Sense: Valid Residual=no mtx: Request Sense: Error Code=70 (Current) mtx: Request Sense: Sense Key=Illegal Request mtx: Request Sense: FileMark=no mtx: Request Sense: EOM=no mtx: Request Sense: ILI=no mtx: Request Sense: Additional Sense Code = 25 mtx: Request Sense: Additional Sense Qualifier = 00 mtx: Request Sense: BPV=no mtx: Request Sense: Error in CDB=no mtx: Request Sense: SKSV=no INQUIRY Command Failed # mtx -f /dev/sg1 inquiry mtx: Request Sense: Long Report=yes mtx: Request Sense: Valid Residual=no mtx: Request Sense: Error Code=70 (Current) mtx: Request Sense: Sense Key=Illegal Request mtx: Request Sense: FileMark=no mtx: Request Sense: EOM=no mtx: Request Sense: ILI=no mtx: Request Sense: Additional Sense Code = 25 mtx: Request Sense: Additional Sense Qualifier = 00 mtx: Request Sense: BPV=no mtx: Request Sense: Error in CDB=no mtx: Request Sense: SKSV=no INQUIRY Command Failed On the other server: tape drive (/dev/st0 not even present). Can someone please help? Thanks, - xinhuan
