Subversion server: v1.4 (centos) vs. v1.6 (rpmforge)
by Mathieu Baudier 17 Dec '09

17 Dec '09

Hi, I'm planning to upgrade an old public/internal development infrastructure and will use CentOS 5.4 x86_64 as basis. One of the critical server is Subversion (as an Apache httpd module). We currently use Subversion v1.4 on the server and v1.6 on our clients. While I was very happy with the v1.4 server over the years, we now sometimes have weird issues which seem related to compatibility with the v1.6 clients (typically working copy depth related). I also want to take the chance of this major overhaul of our infrastructure (and related testing etc.) to upgrade the various components and I'll be happy to benefit from Subversion improvements on the server side as well (especially if it then the version in production for another few years). The Subversion version in CentOS 5.4 is v1.4, whereas RPMForge provides v1.6. I use the RPMForge version as my client on the desktop. - Has anyone of you experience running Subversion servers on CentOS? - Would you in general consider as less secure / safe / stable to use RPMForge packages for such critical tasks? Thanks in advance for your thoughts! Mathieu

Apache + auth_mod_kerb + Active Directory = SSO
by James Bensley 17 Dec '09

17 Dec '09

Hey List, I have been setting up SSO on our Intranet Apache server. All seems well, I think I have just about cracked it but it seems a little rough around the edges; I enabled auth_mod_kerb, and created a test directory in my web root (/secure) and added a directory directive under the httpd.conf, I created a user in Active Ditectory, used ktpass.exe to map the user to the service principal and put the key tab on the Apache server and all seems well. I am testing this with FireFox and Internet Explorer (Both on Windows XP Pro SP3 Client). FireFox works only with the FQDN of the Intranet server (and not just http://hostname/secure, this gives an authentication error), and only with our domain name set in "network.negotiate-auth.delegation-uris" and in "network.negotate-auth.trusted-uris". Internet Explorer however only works with http://hostname/secure and not f.q.d.n/secure? (Integrate with Windows Authentication IS enabled). Obviously as this point the reason I am posting here is because I am trying to eliminate the reasons for this. If it is a client side problem I need to seeks some more savvy IE/Windows users maybe but I am posting here to enquire if anyone has any thoughts about it possibly being DNS related or some sort of server misconfiguration? uname -a Linux hades.nr5project.co.uk 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux Apache/2.2.11 (Unix) mod_auth_kerb/5.4 DAV/2 mod_ssl/2.2.11 OpenSSL/0.9.8k PHP/5.2.9 mod_apreq2-20051231/2.6.0 mod_perl/2.0.4 Perl/v5.10.0 Thanks for reading. -- Regards, James ;) Charles de Gaulle - "The better I get to know men, the more I find myself loving dogs." - http://www.brainyquote.com/quotes/authors/c/charles_de_gaulle.html

mod_security
by Thomas Dukes 16 Dec '09

I installed mod_security yesterday. Unbelievable the amount of crap it will stop in 24 hrs. Picked up the rpm at http://rpm.pbone.net This should be made part of the CentOS extra, contribs or whatever!!

LVM, usb drives, Active Directory
by Scott Ehrlich 16 Dec '09

16 Dec '09

I have a client with a handful of USB drives connected to a CentOS box. I am charged with binding the USB drives together into a single LVM for a cheap storage data pool (10 x 1 TB usb drives = 10 TB cheap storage in a single mount point). The next fun piece is how to incorporate that storage space into an existing Active Directory structure to apply AD acls for limited access. I'd rather not use Samba, as that is its own infrastructure and maintains its own credentials database. What are my best options? Thanks. Scott

Canon Printer Woe
by Colin Coles 16 Dec '09

16 Dec '09

Hi, Has anyone had any success using a Canon LBP5300 with CentOS or any other RH type os for that matter, using the rpms and intructions downloaded from the Canon website? I have it working on XP and OS X both via USB and network but am having no success with either on CentOS 5.4 . Print jobs seem to be processed correctly by CUPS but the printer doesn't respond at all and the jobs show up as completed in the CUPS job list. I do not know how to test the ccpd daemon but it seems to be running. Any pointers greatly appreciated. Cheers, Colin.

bnx2 losing connectivity
by nate 16 Dec '09

16 Dec '09

Hoping someone else has seen this before. I have a few dozen Dell R610 systems with CentOS 5.2 that are using kernels from 5.3 and 5.4 (2.6.18-128.1.10.el5 & 2.6.18-164.6.1.el5), that at random lose layer 2 network connectivity either partially or totally. Running tcpdump on the interface reveals only ARP broadcasts, no responses. Switch reports no packets being received on the interface. Systems can run for days/weeks or even months without an issue then drop off the network. At first I thought it was the Dell switches which we had lots of problems with but it has happened on two other brands of switches as well(Cisco and Extreme), so I no longer believe it's the switch but rather the systems. The workaround is to restart the network on the system. I have even configured the bonding driver to do ARP requests and fail over to the backup link in the event that fails but wasn't successful there either as both links can go down, and/or the system can go into "degraded" state where it can reach some systems but not others. I have ESXi systems running on the same hardware and to-date have not seen any of them drop off the same way. System can be under high traffic load at the time or completely idle, it doesn't seem to make a difference. No log entries indicating what might be going on. I have a case open with Dell but am not expecting a whole lot from them, maybe I'll get lucky though. They asked me to upgrade the NIC firmware which I did on a batch of systems to no avail(the release notes for the firmware said nothing about any fixes that sounded like my issue). Driver versions: ESXi (vSphere): Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.6.9 (December 8, 2007) Most linux systems(5.3 kernel): Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.7.9-1 (July 18, 2008) Some linux systems(5.4 kernel): Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.9.3 (March 17, 2009) Happens across at least a dozen systems spread over 4 data centers. Never seen this sort of behavior before in the hundreds and hundreds of systems I've run. These systems are all new, the R610 hardware was released around May 2009, and we've been having issues since day 1, but only recently have been able to rule the switches out as the cause. The latest driver on Broadcom's site is 1.9.20b which seems odd since CentOS 5.4 seems to come with 1.9.3(the date on the Broadcom site is more recent than the date on the linux kernel driver in 5.4) Most of the fixes in the recent driver versions seem to focus around iSCSI, which I'm not using. lspci says: 02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) Subsystem: Dell Unknown device 0236 Flags: bus master, fast devsel, latency 0, IRQ 114 Memory at dc000000 (64-bit, non-prefetchable) [size=32M] Capabilities: [48] Power Management version 3 Capabilities: [50] Vital Product Data Capabilities: [58] Message Signalled Interrupts: 64bit+ Queue=0/4 Enable- Capabilities: [a0] MSI-X: Enable- Mask- TabSize=9 Capabilities: [ac] Express Endpoint IRQ 0 Capabilities: [100] Device Serial Number c9-dc-93-fe-ff-9b-21-00 Capabilities: [110] Advanced Error Reporting Capabilities: [150] Power Budgeting Capabilities: [160] Virtual Channel I suppose I could go build the latest driver from their site and see how it goes.. thanks nate

Old hd, new machine
by Jussi Hirvi 16 Dec '09

16 Dec '09

What should I do to make an existing CentOS (5.4) disc boot up on a new computer? I just made on CentOS 5.3 installation on that machine, so I know the hardware is compatible. Would it be enough to boot with a DVD in rescue mode, or boot with another hd, and install grub? - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi(a)greenspot.fi * http://www.greenspot.fi
