Help with backups
by Scott Ehrlich 23 Aug '07

23 Aug '07

I've got a Redhat 5 server running Samba, and two dualboot CentOS 5 workstations. Until we get a better backup strategy, I'm backing up the workstations to the server via mounting a shared samba drive to /mnt. Trying tar cvf /mnt/samba_share/backup.tar /* eventually yields backing up /mnt, which produces an unwanted loop, including /mnt/samba_share I looked at tar with --exclude /mnt but didn't seem to get the results I wanted. I tried dump, which looked like it was working, but I have no idea what files it was backing up, and couldn't find an option in the man page to have it show me the files. I would have let it go, but since I couldn't be sure about /mnt recusion, I opted out of it. I ended up, for now, tarring each top-level directory to its own tar file, except, of course, for /mnt. What do people suggest? Thanks. Scott

SATA vs. SAS
by Rajeev R Veedu 23 Aug '07

23 Aug '07

I have 8 WD SATA HDD with raid ready (3mbps) hard disks on a 8 port 3ware controller.(on raid 5.) Does anyone have a comparison on SATA raid and SAS raid disk. As you know SAS disk are very expensive and I would like to know from experts in the list who could suggest which of the following would be the best. Option 1) 2 servers each having 2.0TB raid disk with SAS drives, 2GB ram and standard other features. Option 2) 4 No servers with 1TB each with 2GB ram and standard other features. If Data files (mostly AutoCAD Drawings of size 5MB to 50MB) are distributed as per the above options do you think which could perform better?. As you know the price of SATA disk is much cheaper than the SAS disk and we could nearly by 4 servers for that money. Probability work disturbed by a server crash is low in the second case but I am not sure about the comparison on performance. I would appreciate if you could spread some thought in this regards, and apologize if this is out of topic. Best regards, Rajeev

New server is not discovering USB drive attachment
by Robert Moskowitz 23 Aug '07

Just built a Centos 5 system last night that will be a NAS server. I have a bunch of notebook drives with information I want to populate the NAS with. I am logged in as root. I plug in the USB notebook drive device and nothing. My notebook has no trouble with this device. Obliviously I missed something in the install. autofs is reported as running, so not that.

10+ TB RAID experiences?
by Scott Ehrlich 23 Aug '07

23 Aug '07

I'm looking for RAID options for at least 10 TB to attach to a Dell PowerEdge 2950 running RHEL 5 64-bit Server. The system will act as a single sign-on server for XP and Linux, thus storing user's data from mounted home directories exported from the server to various workstations. It may also house a database. I'll need a storage solution starting at least 10 TB. Most of the SAS devices I've seen go up to 2 TB. Looking at the IBM System Storage devices, for example, they offer 12 TB and up. I'm not sure of the budget, so I'll discount cost for now. How good are IBM's rack RAID devices? I'm just looking at their System Storage DS4xxx line. How about EMC? Network Appliance? Clariion? Quality of unit, reliability of unit andservice and support, overall cost of ownership? Expandability? Thanks for any and all insights. Scott

CentOS v4.5 and Intel 965/G33BY chipsets - PATA support
by Paul Griffith 22 Aug '07

22 Aug '07

Greetings CentOS users, I have run into a hardware issue with the Intel 965 chipset. It appears that the latest kernel doesn't support the Marvell PATA controller. I can kickstart the computer, but after the OS is installed the DVD drive can't be accessed. There are patches against 2.6.18 for the Marvell PATA controller here: http://lkml.org/lkml/2006/10/16/157 There is bug report ported for RHEL 5.0 and I assume this will apply to CentOS 5 also. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=237372 What are my options other that to try to patch the current kernel (2.6.9-55.0.2.EL) ? We have a lab of 24 computer to push out before the start of the term (Sept 5/07) ... joy joy Thanks Paul

Solved: HTTP user directory permissions - Centos 5 post-install
by Robert Moskowitz 22 Aug '07

22 Aug '07

The problem was permissions on /home/user not /home/user/public_html I have not spent the time looking into details, but I booted up the old server (fortunately I had not blown away the drive content yet), and looked at all the directory tree. The permissions for /home/user was drwx--x--x The user that I was using on the new system was the one created by the post-install, first boot process. Its permissions were: drwx------ Other users that I created with drwxx-rx-r So I changed the new system's user directory permissions to match that of the old system, and everything is working. Just one more footnote about installing a new Centos 5 system, check the user directory permissions.

Drivers build easily on CentOS. Just make sure you get drives that are on their compatible list. This may not be as much of an issue now, but I had some problems with drives being marked bad and dropped out of the array when I first set up mine a couple of years ago. This was caused by firmware incompatibilities and fixed by upgrading the drive firmware. Once this was fixed, everything has worked flawlessly since. -- Bowie

Force run of quotacheck at boot
by Dogsbody 22 Aug '07

Hi All, I think I have managed to corrupt my quota files so I need to run `quotacheck` but that needs the partition to have quotas off or be unmounted which isn't ideal for a production system :-p I was trying to find a way to force the system to do a full `quotacheck -cvuga` on a reboot but on looking in rc.sysinit it seems it will only force a quotacheck on boot when fsck finds problems with the disk. Anyone know of a way to force this (touch a file etc.)? Thank you in advance Dan

RE: [CentOS] new CentOS 5 as DNS server
by pctech＠mybellybutton.com 22 Aug '07

22 Aug '07

Hi folks, As a breather from the "thread-now-wider-than-my-headers-window-in-thunderbird" conversation re: mixing repos, I have a question regarding a machine I'm about to put online. :) I run a web hosting company and my secondary (primary to the world) DNS box died from a massive rootkit/hack last night. It was running an old Slackware 9.1 installation and I will be completely cleaning those drives sector-by-sector. After which I'll be installing CentOS 5 on that hardware. As it will be a production server and this is my first foray into CentOS/SELinux in a production environment I was hoping to get a recommended list of what to include and, more specifically, what *not* to include from the distro CDs I will be doing a text based install, hoping to avoid the installation of X. Other than BIND and vsftpd, I don't think I need much. This machine will be pulling zone files from my primary web server and storing some archive files and backups for me. I'm dilligently R`ingTFMs, and will continue to.... I'd sure be appreciative of any jumpstart help and/or any pitfalls of which to be cognizant. ----------------------------------------------------------------- Sorry for my broken ass webmail, but I don't have access to a real mail client at the moment. Personally I would recommend against installing any service that isn't absolutely necessary. Such as FTP. On a DNS server, if that's all it is going to be, there is no need for FTP services. If you need to upload things to the server, use scp, which is a part of SSH. The install is going to add alot of services that you probably won't need on the server, such as sendmail. Shut down any service that you don't need. The fewer services running the fewer attack vectors. You will never get it "hack proof". What you will get is something that "script kiddies" may not bother with in favor of easier targets. Like the old saying goes, "You don't have to run faster than the cheetah. You just have to run faster than the man running next to you." I would also, if possible, disallow root logins to the server via SSH. Configure it so that you have to log in as a normal restricted user and then su to root. ------------------------------------------------------------------ TIA, ~Ray _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

simplest boot to set hardware clock

Well I found a significant source of my problems with these decTOPs. Hardware clock is back at Jan 2006. And many things fail..... And there is no way to access the bios from a boot sequence. On the one I discovered this, I watched everything get errors during all the reboots a Trixbox install goes through. Once I was allowed to log in, I ended using date to set the system date and hwclock to use the system date to fix the hardware clock. Thanks!

Diskless client from system-config-netboot doesn't boot.
by David Mackintosh 21 Aug '07

21 Aug '07

Hi folks, I've followed a set of instructions I found on http://www.linuxtopia.org/online_books/centos_linux_guides/centos_enterpris… which describes using system-config-netboot to set up PXE booting. I used a CentOS-4.3 install (custom, all options de-selected, then anaconda-busybox installed after the fact) as a reference/base. I followed the instructions, extrapolating a bit as the window defining the diskless client has more options than those presented in the example. When I boot the PXE client, it does the pivot root operation, and finally concludes with: SELinux: Disabled at runtime SELinux: Unregistering netfilter hooks ...at which point it hangs for ever. I have tried performing a yum -y update on my reference system, then recreating the root mount point, but it fails the same way. I should probably mention that both the reference and diskless client are identical hardware, and that the hardware has successfully PXE booted a diskless OS (a RedHat 8.0 as it happens) in the past. The lack of any information on the web implies that I'm doing something trivially incorrect, can anyone tell me what it is? Thanks for any hints or pointers you can provide. -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com | http://www.xdroop.com

RAID storage - SATA, SCSI, or Fibre Channel?
by Scott Ehrlich 21 Aug '07

21 Aug '07

I have a Dell PowerEdge 2950 and am looking to add more storage. I know a lot of factors can go into the type of answer given, but for present and future technology planning, should I look for a rack of SATA, SCSI, or fibre channel drives? Maybe I'm dating myself with fibre channel, and possibly SCSI? I may be looking to add a few TB now, and possibly more later. What are people using these days? What throughput and reliability are you seeing? What accounts for the cost differences? Thanks. Scott

Install stops seeing USB CDrom
by Robert Moskowitz 21 Aug '07

21 Aug '07

I have sought information on this in the past. I have a decTOP that I can install DSL on with no trouble from my USB DVD/CDRW drive. Centos won't. Neither 4.4 or 5.0 The boot starts, the CD is being read. After I respond to language, it stops saying it can't find the CD. If I go the linux askmethod approach, I can 'see' it loading the install image from the CD, it goes through the language part. Then when I select Local CD it can't find the CD. So I was thinking. Is there a driver I should be loading? Afterall, this is a DVD/CDRW and MAYBE there is an intrepretation problem? Although I have used this SAME DVD/CDRW to install on other systems.... So it might not be a drive type issue, but rather a USB driver issue? I know from past attempts, if I go the network approach, and select a USB ethernet dongle (the last on the list) it finds my USB ethernet dongle. But that might mean that in this case the install followed a path of first loading a USB driver, and then proceeding. Why not go the Network route? This is a Trixbox install and it is a Trixbox CD.

can't login to remote cvs server
by Kanwar Ranbir Sandhu 21 Aug '07

21 Aug '07

Hi Everyone, I have, for the first time, installed and minimally configured a cvs server on a CentOS 5 box. I followed a "how to" to do the initial configuration, so I'm sure I haven't done anything wrond (according to the "how to", anyway). But, I keep getting this error: $ CVSROOT=:pserver:ksandhu@kermit:/var/cvs/asterisk $ cvs login Logging in to :pserver:ksandhu@kermit:2401/var/cvs/asterisk CVS password: /var/cvs/asterisk: no such repository /var/cvs/asterisk exists, and it's been initialized like so: sudo cvs -d /var/cvs asterisk init I also created "cvsuser" and "cvsadmin", which I've used to set permissions and ownership on /var/cvs/asterisk: drwxrwsr-x 3 cvsuser cvsadmin 4096 Aug 20 14:00 /var/cvs/asterisk I'm stumped. I can't figure out why cvs keeps saying the repository doesn't exist. I'm missing something critical, obviously. Does anyone have any ideas about what I'm doing wrong?

Need help to track an ip port problem
by Erick Perez 20 Aug '07

20 Aug '07

Hi, My centos 4.4 fully updated is going to be used as a mail server. However I did something or i didn't do something and I need some assistance. You see, If I run sendmail in port 25, i can telnet localhost 25 fine. but if I telnet the machine from another machine, the port is refuse. So i tested by running other programs (one at a time) listening to port 25, I cant connect. So It seems that something is blocking specifically port 25 to receive incoming connections. Can I have some assistance as to where to look for a configuration mistake? Basically something has my port 25 blocked on the same machine. BTW iptables is not running.

'service' command not present

I just did an install of CentOS 5 on one of my machines. However, when I try to use the 'service' command (such as 'service httpd start') I get an error that the service command is not found. Why would that be? Where does this command come from? I can launch the services just fine using the respective /etc/init.d/ entries. -- Cheers, Trey ---- Dieters live life in the fasting lane.
