Gentoo? What do you have against the OP? Why subject him to such madness and unnecessary pain? :D In my recent trip through i486 land, I found that Debian seems to be the best bet for nearly all packages being natively available in i386. Also, the installation can be pruned down to a very slim ~140MB if you're careful. Tim Nelson Systems/Network Support Rockbochs Inc. (218)727-4332 x105

Any way to initiate a kickstart from shell prompt?
by Spiro Harvey 09 Dec '09

09 Dec '09

Hi all, I've set up a CentOS flash stick using the LiveCD tools, then dumping that onto flash with a persistent overlay - instructions here: http://wtf.geek.nz/?blog/2009/12/08/how-to-make-a-useful-centos-utility-fla… This gets me to a prompt in which I can do recovery stuff, but I'm curious to know if it's possible to initiate a kickstart install onto the local disks from that prompt. I've got a separate stick that appends ks= lines to boot different kickstart files, but I'd really like to have the ability to do this on the non-auto-install stick too. Is this possible? Is there a command that kicks this off? Cheers -- Spiro Harvey Knossos Networks Ltd 021-295-1923 www.knossos.net.nz

Mic not working with skype
by Andrew 09 Dec '09

I've just installed a beta version of skype in CentOS 5.3 and everything seems fine - the mic is working OK as I can hear it through the speakers (feedback). Problem is I can't get the mic to actually work with skype (eg with skype call testing service) - it may be that one of the many settings is incorrect - has anybody else had this problem and got any suggestions please?

CentOS 5.4 x86_64 only detects 32GB RAM while Fedora x86_64 correctly lists 128GB
by Diederick Stoffers 08 Dec '09

08 Dec '09

Hi, We have a new 24-core Dell PowerEdge R905 server with 128GB's RAM. The 64 bits version of Fedora 12 lists the correct amount of 128GB, CentOS only finds 32GB (and so does Scientific Linux). I would much prefer to use CentOS (most of the software we use is specifically designed for CentOS). Does anyone know what is causing this/how to fix it? Many Thanks, Diederick

Xorg goes bonkers, bazillion NVIDIA errors...
by fred smith 08 Dec '09

08 Dec '09

on one of my Centos 5.4 boxes, a machine that's around 5 years old and has always run Centos and X, and has had the same Nvidia card in it for its entire life, I'm suddenly getting these lines in the xorg log file: (WW) NVIDIA(0): WAIT (2, 6, 0x8000, 0x00000000, 0x000003c0) (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** followed by millions more like them. it's currently sitting mostly unused, except that it's running a Folding At Home client. it'll run for a day or a week then I'll note the screen is in powersave mode, will attempt to wake it up by moving the mouse or touching a key and nothing happens. (for purposes of this testing I've disabled the screensaver, so the screen should never shut off.) I can SOMETIMES ssh into it, if it hasn't completely died yet, and if I can, top shows that Xorg is consuming about 99% of the CPU instead of the folding at home client which should be consuming most of it. I guess it's busy spewing errors to the Xorg log file, or something. The last time I found it like this I tried to kill xorg. kill -15 wouldn't kill it so I tried kill -9, then the whole box seized up, requiring a reset. sometimes it's already unresponsive, even to ssh or ping, by the time I notice the problem. it's running an old Nvidia Geforce 4 MX400 card and the Nvidia proprietary driver NVIDIA-Linux-x86-96.43.01-pkg1.run, downloaded directly from the nvidia web site. the date on that file is Oct 2007, so that means that's the one that it has been using since then. but it's only the last 6 weeks or so it's started doing this. other than some vaguely-defined "nvidia driver problems", what may be going on here? (I can buy an nvidia conflict with the stock centos kernel, but I'd be dubious, since it's been running this driver for two years and earlier versions for 4 or 5. any such conflict would seem likely a kernel issue, to me, since it's newly exhibited.)

firefox-3.0.15 on CentOS 4
by Agile Aspect 08 Dec '09

08 Dec '09

Hi - I updated firefox-3.0.5 from firefox-3.0.15on CentOS 4 this weekend and now I can't start it because it has the wrong version of NSS and I can't update NSS to the correct version. Does anyone know where I can find the RPM for CentOS 4 version of firefox-3.0.5? Or how I can tell yum to install version firefox-3.0.5 instead of firefox-3.0.15? Thank you. -- Enjoy global warming while it lasts.

how to do startup scripts?
by Roland Roland 08 Dec '09

08 Dec '09

Hello, I've just finished installing Atlassian's bamboo it comes with two ways to start it up one through a bash shell script bamboo.sh and another through java script (this one is better as it has the ability to start up the service if it got shutdown for any reason) so I'm wondering how can I set this service to start on boot.. I know how to set a script on login in my profile though not on boot.. any suggestion? I've looked around about none interactive shells and so on.. so if I did a symbolic link from bamboo.sh script to /etc/init.d would that work? what about variables inside the script would they b read ? obviously a newbie here so appreciate any detailed explanation if possible about interactive/ none interactive shells and of course if theres an advice about how to solve this issue.. PS: trying to educate myself about linux along the way so any explanation would be greatly appreciated...

lvm monitoring
by Karanbir Singh 08 Dec '09

08 Dec '09

Hi, At the moment, I am monitoring my lvm resources on a machine with the usual 'pvs;vgs;lvs' output and comparing with whatever is a known good state. But this has a few problems: 1- I need to setup a known good state per machine, which can look quite different from each other : specially when machines are getting dynamic vm builds and teardowns dozens of times per day, or when disk resource allocations are spread over more than one machine. 2- Its hard to work out what is really going on with bits that are not mounted ( like snapshots ). 3- its hard to tie down to physical media ( I screen scrape at the moment, which is dirty and exceptionally prone to nose! ) I am sure there are plenty of people who are monitoring lvm setups on their machines, just wondering what it is that you guys are doing. - KB

XFS is the most stable file system I've seen or used. I've seen it survive power failures and disk problems with out a problem. It is the ONLY file system I trust. It is stable, reliable, dependable, and practically bullet proof. I've been using XFS almost since it came into existence on SGI's (IRIX) and we've been using it under Linux for years too, also with out problems.

Kickstart wrong swap size
by Lars Hecking 08 Dec '09

08 Dec '09

All machines kickstarted here consistently have a swap partition with the wrong size. According to the RHEL5 manual: | To determine the size of the swap partition automatically, use the | --recommended option: | | swap --recommended | | The recommended maximum swap size for machines with less than 2GB of RAM is | twice the amount of RAM. For machines with 2GB or more, this recommendation | changes to 2GB plus the amount of RAM. However, the swap partition on all kickstarted machines is 2GB, regardless of RAM size. This is the relevant portion of the kickstart file: bootloader --location=mbr selinux --disabled reboot clearpart --all --initlabel part /boot --fstype ext3 --size=102 part / --fstype ext3 --size=20480 part swap --recommended part /var --fstype ext3 --size=1 --grow The kickstart setup is currently based on CentOS 5.2 (and I cannot move to 5.4 yet as this is a corporate setup affecting hundreds of machines). Hardcoding swap size isn't a good idea either because there's a range of different memory configurations. I could however confirm that a manual, graphical install from the 5.4 DVD with recommended settings creates 10GB swap on a 8GB RAM machine.

Resizing / partition ?
by armann 08 Dec '09

08 Dec '09

Hi. I know this has probably been discussed a lot so I'm sorry, noob here. I found a good tutorial here: http://fedorasolved.org/Members/zcat/shrink-lvm-for-new-partition My only problem is understanding this. "To calculate the new End sector, ADD the partition Start sector to the PV PSize, and then add a safety margin of around 131072 sectors (64MB) to that." If anybody has another way of doing this or any comments that would be great. Thanks. Armann Jakob Palsson

centos vs rhel vs scientific linux
by Robert P. J. Day 07 Dec '09

07 Dec '09

i'm prepping to teach a 5-day intro class in linux starting in about 3 hours, and the courseware is clearly designed around RHEL (apparently 5.1). but since i'm not being provided with RHEL DVDs, i'm just going to hand everyone a centos 5.4 DVD and take it from there. as part of the intro, i want to briefly discuss the varieties of linux related to RHEL, so obviously i want to mention what centos is all about. in a nutshell, it's simply RHEL with any RH-proprietary branding removed, yes? what's the simplest way to sum up the difference in a sentence or two? and i've never used SL but, again as i understand it, it's also RHEL unbranded but, IIRC, SL is more open to producing updates, whereas centos is rigourous about tracking the corresponding RHEL version. does that sound about right? rday -- ======================================================================== Robert P.

OT: How can I tell if a web site is now blocking IPs from my country?
by Lanny Marcus 07 Dec '09

I have always been able to browse, without any problems, http://www.mobile-review.com/index-en.shtml but for the past 2 or 3 days, Mozilla Firefox just hangs "connecting to ...." How can I tell if they have started blocking IP addresses from Colombia? I would like to do that, before I post to the IPCop mailing list. I have my IPCop box set up to do DNS Caching, so possibly something went awry there. I use OpenDNS.com and I refreshed their Cache for this web site. I am not having problems browsing other web sites. The site is up and my desktop is dual boot and the same thing happens if I boot to M$ Windows. TIA!

Building xfsprogs can't find valid UUID library
by C Linus Hicks 06 Dec '09

06 Dec '09

On CentOS 5.3 x86_64, I'm trying to build xfsprogs-2.9.4-1.el5.centos.x86_64 with -ggdb so I can use it with gdb and examine the data structures when using xfs_db. I've installed the src rpm as a non-root user and when I run rpmbuild -bc during the ./configure I get the error: . . . checking uuid.h usability... no checking uuid.h presence... no checking for uuid.h... no checking sys/uuid.h usability... no checking sys/uuid.h presence... no checking for sys/uuid.h... no checking uuid/uuid.h usability... yes checking uuid/uuid.h presence... yes checking for uuid/uuid.h... yes checking for uuid_compare... no checking for uuid_compare in -luuid... no FATAL ERROR: could not find a valid UUID library.

CentOS/RHEL's build of firefox hardwired to evolution -- how to change this
by Robert Heller 05 Dec '09

05 Dec '09

For some awful reason (can someone explain why?), the RHEL/CentOS build of firefox is hardwired to use evolution as its mailto client. With FF 2.<mumble> this was fixable with an about:config setting. With 3.0.<mumble>, it seems not. What is the proper way of fixing this? *I* ended up doing a 'sudo rpm -e evolution' and then doing a 'sudo ln -s <myfirefoxmailtohandler> /usr/bin/evolution'. This is a truely ugly/bad solution, but it is the only one I know of. Please tell be of a better solution. (Hopefully not one that requires me to download the firefox SRPM and hacking the .spec file -- re-building building firefox from sources is non-trivial -- I'd *rather* drop random symlinks into /usr/bin, bad as that is.) *I'm* tempted to report this as a serious *bug* (I really consider it so). -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

two questions about ssh tunneling
by Tudod Ki 05 Dec '09

05 Dec '09

if I: ssh -fND localhost:6000 somebody(a)192.168.56.5 -p PORTNUMBER from computer "A" to computer "B" [B = 192.168.56.5] then I can set the SOCKS proxy for e.g.: Firefox to use "localhost:6000" on computer "A". Ok. I can surf the web through "B". But: - Can anyone sniff the traffic of "A"? [e.g.: computers on same subnet as "A"] Like DNS requests? - I think no, but I'm not sure :O - Can anyone sniff the traffic of computer "B"? e.g.: B computer is at a server farm [others in the farm can see the traffic?] - I think yes, but I'm not sure :O

centos 5.4, firefox and adobereader plugin, disabled input fields
by Waldemar Gorus 05 Dec '09

05 Dec '09

Hello, we are using firefox-3.0.15 from the CentOS-Repository and the adobereader plugin from the adobe-repository. We have a curious problem with adobereader-plugin in firefox. When a pdf document is displayed via the plugin, i.e. within a tab in firefox, all input fields are disabled. I cannot enter a search string or fill in fields. The cursor and page up/down keys are also disabled. But when I configure firefox to open pdf documents with the external acroreader, everything works fine. Additional notes: * We are just migrating from SuSE. Some user profiles are working as expected without problems. Unfortunately, I was not able to figure out the important files: I traced all of firefox' file operations on the user profiles, but there are no significant differences between working and non-working profiles (I just compared filenames, not content). * the same adobe-plugin works with firefox 3.0.15 from mozilla.org * I also set up a clean i386-Centos 5.4 from original CD, SELinux disabled, updated and created standard user. I only added the adobe-repository. The same effect, no search avaible. I would be grateful about a solution (of course :-), but also for ideas on how to debug this problem. bye Waldemar

measuring iops on linux - numbers make sense?
by Amos Shapira 05 Dec '09

05 Dec '09

Hello, When approaching hosting providers for services, the first question many of them asked us was about the amount of IOPS the disk system should support. While we stress-tested our service, we recorded between 4000 and 6000 "merged io operations per second" as seen in "iostat -x" and collectd (varies between the different components of the system, we have a few such servers). A couple of hosting providers told us that this (iostat and collectd "merged operations per second") is a not so bad way to get IOPS. A partner of ours doubts that this is possible with the current hardware - a 3ware 9690SA-4I4E (http://www.3ware.com/products/sas-9690SA.asp) with 512Mb battery backed up cache and 8 SAS 15k rpm disks (SEAGATE ST3300656SS) in RAID 1+0. They calculate 750 IOPS per spindle and say that the maximum they ever saw from any 15k disk was 350 iops on RAID 0. Am I measuring the numbers correctly? Is there a better way to measure IOPS on CentOS? The OS is CentOS 5.3 x86_64, the rest of the hardware is 64Gb RAM, 2 quad-core 3GHz Intel Xeon CPU's. Thanks, --Amos

proper protocol for installing a *really* new package?
by Robert P. J. Day 05 Dec '09

05 Dec '09

what is the proper approach to install on centos 5.4 a package that's newer than the currently supported one? at the moment, AFAICT, the latest "poppler-utils" package for centos is 0.5.4. however, the source is up to version 0.12: http://poppler.freedesktop.org/ which matches the current fedora version, but that's not surprising since, naturally, fedora zips right along keeping up with that sort of thing. however, i have a case where it's important that a newer version of poppler-utils (and, consequently) poppler be installed on a centos 5.4 box. someone has claimed he's done it by (gack! choke!) installing the fedora package. that just creeps me out. in any case, what would be the proper solution under centos? is there a "rawhide"/dev equivalent for centos? thanks. rday -- ======================================================================== Robert P.

Centos 5.4 on Acer Aspire One
by Frank Cox 04 Dec '09

04 Dec '09

I currently have my Acer Aspire One netbook set up with Fedora 11. I would like to change it over to Centos 5.4 if I can. I downloaded the Centos 5.4 i386 livecd image and made a bootable USB flash drive out of it. Unfortunately, when I boot off of that flash drive, Grub (I guess) immediately turns the screen entirely white. If I hit a key I can faintly see the outline of "Press tab to change options" or words to that effect. (It's very faint and hard to read against the white background.) That bit of text rapidly scrolls off of the top of the screen, so I assume that the rest of the boot-up messages are being printed. Hitting Ctrl-Alt-anyFkey does nothing for a while, then every keystroke beeps. I can't get to a text terminal and I never see anything other than a completely white screen. Am I doing something wrong? Fedora 11 works fine on this machine, and I installed that from a livecd. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

Getting EXTERN.h, perl.h, etc
by Charles E Campbell Jr 04 Dec '09

Hello: I have a Fedora Core 11 system at home (Centos 5.2 at work). I'd like to build vim with huge and perl. This works under Centos, but fails at home: no EXTERN.h or perl.h (and, presumably, other things). So: is there a yum package I should be downloading, and if so, which one? (both the home computer and the work computer are 64-bit systems) Thank you, Chip Campbell -- someday I'll have a good signature, I'm sure of it...

Kerberos + NFSv4 difficulties
by Dan Burkland 04 Dec '09

04 Dec '09

Hey All, I recently have been trying to setup an NFSv4 share that utilizes Kerberos. My experience in general with NFS is very slim however I feel like I am very close to getting this project completed. Currently I have the following things in place: 1) NFS server nfs.example.net (VM#2) - Running CentOS 5.4 with all of the latest updates and NFS-related packages 2) Kerberos KDC running on Kerberos.example.net (VM#1) - Running CentOS 5.4 with all of the latest updates 3) NFS client nfs-client.example.net (VM#3) - Running CentOS 5.4 with all of the latest updates Before I give you the error message I receive when I enable NFS, I'll first describe my setup process. 1) Verified Kerberos works on all machines by attempting a kinit testuser which worked properly. 2) Verified that the clocks on all machines represent the same time (synced using a local NTP server) 3) Created a service principle for nfs.example.net by performing the following commands on the nfs.example.net machine: - (Performed on NFS server) a. kadmin (Logged in as an admin principle) b. addprinc -randkey nfs/nfs.example.net c. ktadd -e des-cbc-crc:normal nfs/nfs.example.net d. quit e. kinit nfs/nfs.example.net -k -t /etc/krb5.keytab f. klist to verify 4) Edited /etc/idmapd.conf with the following changes: - (Performed on NFS server) a. changed Nobody-{User,Group} to nfsnobody b. changed Domain to nfs.example.net 5) Mkdir /nfs/ - (Performed on NFS server) 6) Added the following to /etc/exports - (Performed on NFS server) a. /nfs gss/krb5p(rw,sync,fsid=0) 7) exportfs -rv - (Performed on NFS server) 8) Verified all relevant nfs services were stopped - (Performed on NFS server) 9) Uncommented and made the following changes to /etc/sysconfig/nfs - (Performed on NFS server) a. MOUNTD_NFS_V1="no" b. MOUNTD_NFS_V2="no" c. RPCNFSDARGS="-N 2 -N 3 -U" d. SECURE_NFS = "yes" 10) /etc/init.d/portmap start; /etc/init.d/rpcidmapd start; /etc/init.d/nfs start - (Performed on NFS server) 11) And I receive the following output when the nfs service starts: a. Starting RPC svcgssd: FAILED b. Starting NFS Services: OK c. Starting NFS quotas: OK d. Starting NFS daemon: NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory e. NFSD: starting 90-second grace period f. Starting NFS mountd: OK 12) I then checked /var/log/messages to find the following log entries: a. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: ERROR: GSS-API: error in gss_acquire_cred(): Unspecified GSS failure. Minor code may provide more information - No principal in keytab matches desired name b. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: Unable to obtain credentials for 'nfs' c. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: unable to obtain root (machine) credentials d. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: do you have a keytab entry for nfs/<your.host>@<YOUR.REALM> in /etc/krb5.keytab? I seem to be stuck at this point and would appreciate your insight.

Re: [CentOS] Small proxy appliance hardware
by Chuck Munro 04 Dec '09

04 Dec '09

Regarding a small proxy appliance, my thanks to those who responded either on this list or by direct email. We are going to get one of the little Acer AspireRevo 3610 boxes and give it a try. It's small, quiet, runs cool, and has more than enough resources to handle our CentOS proxy application. It's a shame that we have to trash the Windows-7 install (a waste of money) but that's life. The only unanswered question is with regard to an external USB wired network adapter, so we'll have to go by the data on the various manufacturers' web sites about Linux support. Has anyone tried the Belkin USB2/Gbit, the D-Link DUB-E100 or the Linksys USB300M devices? Which adapter chips to they use (in other words, which driver)?

LDAP for central authentication?
by Scott Ehrlich 04 Dec '09

04 Dec '09

I have the following on a network: 1) RHEL 5.0 Server acting as NIS and Samba domain controller 2) CentOS 5.x machines on NIS network 3) Win XP machines on Samba domain When I create an account for someone, I need to first type adduser new_person -d /home/new_person then passwd new_person, then cd /var/yp and make. Then smbpasswd -a new_person. Thus, two different databases. On another network, I have separate XP and Linux (CentOS 5.x, RHEL 5.x, and Suse) systems. No Samba, no NIS. Can I still set up a central LDAP directory for a single account database? For the NIS+Samba case, can I merge both credential files into a central database using LDAP? I would also want to control password length, complexity, aging, and other things. What is the best way to do this? Thanks. Scott

Fedora 11 i386 Evolution address book --> CentOS 5.4 x86_64
by David McGuffey 04 Dec '09

04 Dec '09

Finally moved my home desktop from Fedora to CentOS. My spouse was unhappy with me upgrading from F9-->F10-->f11 etc and wanted something more stable. I built a second machine which is now running in parallel to the old F11 desktop. I moved my data (mail and files) from the F11 box to the CentOS 5.4 box. I used tar to move everything. Mail and files transferred A-OK...but the Evolution address book did not. Any tips on getting the old /home/.../.evolution/addressbook which worked with the version of Evolution on the new machine with an older version of Evolution? BTW, on CentOS, I cannot add new addresses to the address book. User_id on the new machine is the same as on the old machine, so perms should not be the problem. I checked the selinux context and it is the same as everything else in /home If I do a forced reinstall of Evolution would it mess up the mail files? DaveM

RIPd not announcing routes (CentOS 5.4)
by Timo Schoeler 03 Dec '09

03 Dec '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, yesterday I sent this eMail to quagga mailing list, however I didn't receive an answer yet. Unfortunately, I really need this stuff running or have to switch to another strategy achieving the goals. Maybe one of you has some experience on this topic and can shed some light on it -- I really appreciate it. - -----8<-----8<-----8<----- I have a setup here that requires me to announce dynamic route that are created (within some virtual machines) on my CentOS-based machine. Config looks like this: (ripd.conf) ! hostname bla.foo.org password something enable password somethingother log file /var/log/quagga/ripd.log debug rip events ! router rip ~ version 2 ~ redistribute kernel ~ passive-interface default ~ network eth1.123 ~ network eth1.124 ! ~ no passive-interface eth1.123 ~ no passive-interface eth1.124 ! line vty ! Now, the problem is that it seems to distribute its routes (as my Cisco network guy told me), but it does not learn the routes announced by the (Cisco) neighbours: The speaks to a bunch of Cisco routers (which do, among OSPF and BGP routing, redistriubution of lots of stuff via RIPv2, which should feed my machines). The logfile (as configured above in the config) seems okay (except a "RIP: update timer fire!" entry every now and then): 2009/11/30 10:16:47 RIP: RIPd 0.98.6 starting: vty@2602 2009/11/30 10:16:47 RIP: turn on eth1.123 2009/11/30 10:16:47 RIP: Redistribute new prefix x.x.x.x/14 on the interface eth1.123 2009/11/30 10:16:47 RIP: triggered update! 2009/11/30 10:16:47 RIP: turn on eth1.124 2009/11/30 10:16:47 RIP: Redistribute new prefix y.y.y.y/16 on the interface eth1.124 2009/11/30 10:16:48 RIP: multicast join at eth1.123 2009/11/30 10:16:48 RIP: multicast request on eth1.123 2009/11/30 10:16:48 RIP: SEND to 224.0.0.9.520 2009/11/30 10:16:48 RIP: multicast join at eth1.124 2009/11/30 10:16:48 RIP: multicast request on eth1.124 2009/11/30 10:16:48 RIP: SEND to 224.0.0.9.520 2009/11/30 10:16:48 RIP: RECV packet from z.z.z.1 port 520 on eth1.123 2009/11/30 10:16:48 RIP: RECV packet from z.z.z.2 port 520 on eth1.123 2009/11/30 10:16:48 RIP: RECV packet from z.0.0.3 port 520 on eth1.123 2009/11/30 10:16:48 RIP: RECV packet from z.z.z.121 port 520 on eth1.124 2009/11/30 10:16:48 RIP: RECV packet from z.z.z.122 port 520 on eth1.124 2009/11/30 10:16:48 RIP: RECV packet from z.z.z.123 port 520 on eth1.124 ...

Maybe this is something trivial but I don't see it as I'm new to quagga. Help greatly appreciated.

(re)load new kernel with rebooting host node?
by Rudi Ahlers 03 Dec '09

03 Dec '09

Hi all, Is it possible to reload the dom0 / host node's kernel with a newer one, without rebooting the server? I know kexec can do something like this for security patches, but I don't know much about kexec, and I don't want to mess up a production server either. So, has anyone done something like this before? I need to load a new kernel for one of the domU's iptables to work, but don't want to reboot the whole server and cause downtime for the other domU's. -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

CentOS 5.3 - changing display settings
by Andrew 03 Dec '09

03 Dec '09

I've just installed CentOS 5.3 on my desktop and need to change the installed display setting from 1280x1024 to 1024x768 (more suitable for my monitor). When I try this on the Display Settings tab, I get the message: "Display settings changed You need to log out and restart the X server for the changes to take effect. Configuration was written to /etc/X11/xorg.conf, original configuration saved as /etc/X11/xorg.conf.backup." Trouble is, I don't know how to restart the X server apart from rebooting the computer, but that has no effect and the display settings remain unchanged! Any help appreciated, Andy

Small proxy appliance hardware
by Chuck Munro 03 Dec '09

03 Dec '09

I need to configure a small proxy appliance which doesn't require a lot of CPU power. I'm looking for any warnings this group may have regarding CentOS-5 on the following: - Acer AspireRevo 3610 (Atom CPU) - Dell Inspiron 537s (Celeron) - Any other small machines you might recommend (UL approved) I need to implement dual NICs, and for the Dell it should be no problem finding a low-profile 3Com or Intel adapter, but for the Acer I'll need to use one of those USB wired network dongle things. Does anyone have recommendations for a USB dongle that is fully automatic (regarding speed and duplex negotiation) supported by CentOS? Gigabit speed is not required. Any other compatibility issues with the above machines? Normally I'd simply build something from components and squeeze it into a small box, but in this case I need something with UL/CSA/CE approvals, which lets out homebrew hardware. Many thanks in advance!
