Question on httpd
by Jerry Geis 19 Dec '11

19 Dec '11

I have been requested to ensure the httpd on a server is version 2.2.21 or later. How do I verify that? On CentOS 5.7 x86_64 it says its version 2.2.3-53. is that equivalent to 2.2.21 in RedHat land with the way they do versions? Thanks. Jerry

Backup Redux
by Alan McKay 19 Dec '11

19 Dec '11

Hey folks, I just went through the archives to see what people are doing for backups, and here is what I found : - amanda - bacula - BackupPC - FreeNAS Here is my situation : we have pretty much all Sun hardware with a Sun StorageTek SL24 tape unit backing it all up. OSes are a combination of RHEL and CentOS. The software we are using is EMC NetWorker Management Console version 3.5.1.Build.269 based on NetWorker version 7.5.1.Build.269 The pickle we are in right now is that this software is Java based, and stops working at a very specific release of JRE (1.6.26 or something like that). We still have some machines around with that release and it looks like we need to keep at least 1 of them, but this is clearly not a long term viable solution. In the end I want to get our central IT group to take over our backups if possible (we are a bit of an island outside of central IT), but as I pursue that path I also want to pursue a 2ndary path assuming they will say "no". I am familiar with BackupPC and will look at the other recommendations above. I think that Bacula and Amanda are sort of the drop-in replacements for what we have now so I'll look at them most closely. But if I do have to carry forward with our own backups I'd ideally like to get out of the tape game - never liked tapes. Anyway, since the last big backup discussion was over a year ago I figured I'd kick off another one to see if anything new has come up in the mean time. What are the current recommendations? cheers, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

6.x - find interface with link up
by Les Mikesell 19 Dec '11

19 Dec '11

In earlier versions 'mii-tool' would iterate over interfaces and show which have link up. In 6.x it wants an interface as a parameter. What is the appropriate way to find which of some number of of interfaces are connected? Better yet, what is the least typing to get the mac addresses of those interfaces? -- Les Mikesell lesmikesell(a)gmail.com

Random Proliant Crashes CentOS 6.1
by John Hinton 18 Dec '11

18 Dec '11

I've been seeing some random Proliant DL380 G4 64bit crashes. Each time, on the console are messages relating tojbd2/cciss and something about a waitfor 120 seconds. Is anybody else seeing anything like this? Oddly, I can't seem to find this in the logs. I guess it can't write when this happens. -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online Solutions

Static routes with a metric?
by Matt Garman 18 Dec '11

18 Dec '11

Hi, How can I define static routes to be created at boot time with a specific metric? I have two NICs that ultimately end up at the same peer, but literally go through two completely different networks. IOW, each NIC connects to a different layer 3 device. Also, note that the machine actually has three total NICs: the third is the owner of the default route. The two mentioned above are for a specialized sub net. What I basically need to be able to do is this: route add -host h1 gw g1 metric 0 route add -host h1 gw g2 metric 10 Notice that everything is the same except the gateway and metric. I could put this in /etc/rc.local, but was wondering if there's a cleaner way to do it in e.g. the network-scripts directory. Thanks, Matt

how to find source of data loss / corruption
by Rudi Ahlers 18 Dec '11

18 Dec '11

Hi, 2 websites, hosted on 2 different CentOS 5.7 servers (one being very new, about 3 weeks old) keeps loosing data - but it's more like it's corrupted than being deleted. For example, a photo would be uploaded last night and today when we checked it, it doesn't show on the website. So we check if the file is on the server, and exists but is 0KB in size. Last night it still worked fine. The photo is 482Kb in size. The first time this happened we thought it was due to a bug with CentOS 5.7 + EXT4 + quotas (there's a bug open for this) and since the server's console kept giving errors about possible data corruption we thought it would be best if we move everything to a more stable platform. So we brought a new server, setup CentOS 5.7 + ext3 + quotas (which has been working fine on all our servers for a long time) and moved the data across. A few days down the line and I still see this happening. I'm out of ideas and hope someone could shed some light on the matter. I've checked some suggested search results, but couldn't find any issues with the HDD according to SMART. The servers' both have 4GB RAM and 8Core CPU's.Neither RAM, nor CPU usage is high. Both are setup with RAID10 across 4 entrerprise HDD's, one server has software RAID and the new one hardware RAID. So even when we changed the RAID subsystem it still happens. -- 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 5.7 gives me a blank screen after bootup
by Rudi Ahlers 18 Dec '11

18 Dec '11

Hi all, I have an odd problem, for which I couldn't find any suggestions on google. A CentOS 5.7x64 gives me a blank screen on bootup, both to the 17" LCD monitor connected to the VGA port, and to the KVMOVIP device built-into the server, I can see the GRUB boot loader, and everything booting up, upto the point where it says "Waiting for driver initialization.", then it goes blank - both on the LCD and the KVM. Does anyone know how to fix this? It does the same whether I boot into the CentOS, or XEN kernel, or in single user mode. First few lines of /etc/grub.conf: # initrd /initrd-version.img #boot=/dev/md0 default 0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-274.7.1.el5xen) root (hd0,0) kernel /xen.gz-2.6.18-274.7.1.el5 dom0_mem=786M module /vmlinuz-2.6.18-274.7.1.el5xen ro root=/dev/LVM01/root nofb module /initrd-2.6.18-274.7.1.el5xen.img title CentOS (2.6.18-274.7.1.el5) root (hd0,0) kernel /vmlinuz-2.6.18-274.7.1.el5 ro root=/dev/LVM01/root nofb initrd /initrd-2.6.18-274.7.1.el5.img root@zaxen02:[~]$ uname -a Linux zaxen02 2.6.18-274.7.1.el5xen #1 SMP Thu Oct 20 17:06:34 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux root@zaxen02:[~]$ cat /etc/redhat-release CentOS release 5.7 (Final) -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532
