Re: [CentOS] How to disable screen locking system-wide?
by Giles Coochey 22 Jan '11

And in those nine years you claim to have had at least one major security incident. It beggars my belief.... You now publicly declare that your company not just advocates the sharing of passwords, but certainly encourages it, if not make it compulsory. If you were to have another security incident you would probably be hard pressed to be able to point the finger at anyone, especially as your lax security procedures are now public knowledge. Troll?

But I've been running a hosting & development company for 9 years now and this is the first problem I get out of the way right on the first day of an employees job. I'm personally involved in the accounts department (when I actually get time) since I want to know what goes on in my company. I also work close with the developers when needed. We trust everyone in the office, and being it an open-plan office, it's easy to see if someone is at someone else's desk when they're not supposed to be. Staff logoff and shutdown every night, so that's not an issue. But, it is a big issue when a staff member goes on leave, or even just on lunch and switch-off their cellphones and I can't get hold of them to get a password to login to a PC if I need to. The account PC, for that matter is encrypted, with no network access so one needs to be in front if it to access the data. User accounts also doesn't mean much to me. I know how it sounds, but I care more about the data than the user's account. As long as I can access whatever I want, whenever I want. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

Hi all, I'm running Centos 5.5 with Xen 4.0.1 Would like to use a USB key (not a block device) in my domU.

CentOS and Dell MD3200i / MD3220i iSCSI w/ multipath
by Edward Morbius 22 Jan '11

22 Jan '11

We've been wrestling with this for ... rather longer than I'd care to admit. Host / initiator systems are a number of real and virtualized CentOS 5.5 boxes. Storage arrays / targets are Dell MD3220i storage arrays. CentOS is not a Dell-supported configuration, and we've had little helpful advice from Dell. There's been some amount of FUD in that Dell don't seem to know what Dell's own software installation (the md3 Dell doesn't seem to have much OS experience generally. Their docs are pretty inconsistent. I've noted omissions, terminology differences, and procedural differences among the "Owner's Manual", "Deployment Guide", a professional services "Remote Services Installation Agreement" service description. Some of the multipathing guidance we've had comes from their EqualLogic line of storage servers. Questions: 1: Is there anyone out there running this configuration and are you satisfied with it? 2: We get a set of error messages on the initator at target login. These appear to be benign, and web research suggests it's the result of a driver configuration issue in trying to send instructions to a http://comments.gmane.org/gmane.linux.iscsi.open-iscsi/5970 http://bit.ly/gguLl7 MD3000i boxes have 1 controller that can execute IO and one that cannot execute READ/WRITE IO until a special command is sent. In older kernels, layers like the partition scanning and udev and hal would send down IO to those disabled paths and we would see IO errors like in your link. In newer kernels we have device handler modules (for MD3000i you would want scsi_dh_rdac (so do "modprobe scsi_dh_rdac" and then lsmod to see if it is there)) that will detect if the path is not active and if so it will either not send the IO or it will not print a error message since we expect the IO to fail. We'd prefer *not* seeing spurious I/O errors that we don't have to sift through looking for real storage issues. 3: The MD32xxi series is a dual-controller array with multiple ports on each controller. Multiple targets can be logged into from an initiator, with the pathways aggregated by the Linux multipath (device-mapper-multipath) system. There's very little clear documentation on multipath. In particular, any way to trigger alerting from multipath events / failures, or iscsi session actions, would be helpful. The MD32xxi series only supports reporting from a GUI management utility (MDSM) which would be at best problematic to run in a server environment. The other question is: is multipathing typical of iSCSI configuation? Little of the iSCSI docs I've found discusses multipath configurations at all: http://www.open-iscsi.org/ http://www.cuddletech.com/articles/iscsi/index.html (good but very dated) http://www.cyberciti.biz/tips/rhel-centos-fedora-linux-iscsi-howto.html (no mention of multipathing) 4: Dell suggests a shutdown procedure including a flush of multipathing paths ("multipath -F" -- in the "Owner's Manual"): 3 Flush the Device Mapper multipath maps list to remove any old or modified mappings # multipath F Presumably this would go into one of the init scripts -- perhaps the /etc/init.d/multipath script, as part of the "stop" sequence (after the multipath daemon is killed). Anyone done this or know why the practice is recommended? Based on our experience with Dell I would NOT recommend this configuration for others. But we're stuck with it, and any help in getting things configured would be very helpful and gratefully received. I'm also hoping to get clearance to release docs we've generated, though that's the subject of some internal negotiation. -- Dr. Ed Morbius Chief Scientist Krell Power Systems Unlimited

I want to install smarmontools v 5.40, and so I pulled the SRPM for 5.39 so I could patch and install... $ wget -Nc ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Workstation/en/os/SRPMS/s… However, the install of the source fails. $ rpm -ivh smartmontools-5.39.1-2.el6.src.rpm warning: smartmontools-5.39.1-2.el6.src.rpm: V3 RSA/MD5 signature: NOKEY, key ID fd431d51 1:smartmontools warning: user mockbuild does not exist - using root warning: group mockbuild does not exist - using root ########################################### [100%] error: unpacking of archive failed on file /home/jmccarty/devtools/RebuildRPM/build/SOURCES/smartd.initd;4d39deaa: cpio: MD5 sum mismatch Is the SRPM corrupted? I've pulled a few from other places for other versions (like Fedora) from pbone, and they all have this problem. Any hints available?
