Has anyone got a Bluetooth PAN up and running? PAN::= Personal Area Network -> TCP/IP over bluetooth. If so how did you configure it? Like getting a ifcfg-pan0 or some such configured.

Anyone using TCP Connection Passing?
by Amos Shapira 04 Jul '08

04 Jul '08

Hello, We are looking at ways to improve our cluster fail-over and one thing that we wonder about is the possibility of passing tcp connections from the primary server to the secondary when the primary dies. I found tcpcp (http://tcpcp.sourceforge.net/) and tcpcp2 (http://tcpcp2.sourceforge.net/) but they seem to be inactive (last release was two years ago) and requires also changes in the application level. I though that I saw somewhere an implementation of the simple idea of having the secondary tracking the connections (sort of "shadowing" the primary) and when the primary disappears it can take over everything. e.g. the following points to some interesting links: http://archive.gscept.com/2006/dev/?p=266 Has anyone here got to implement something like this? Our platform is CentOS 5 x86_64. Thanks, --Amos

Root-filesystem remounts as read-only during 5.2 upgrade (system completely shoot)
by Bernhard Gschaider 04 Jul '08

04 Jul '08

Judging from the frequency of my messages here one could think that I'm too stupid to upgrade a workstation to 5.2 (but the servers I've tried work without problem) OK. The problem: I've tried to upgrade a 5.1-x86_64-workstation to 5.2. During the upgrade immidiatly after (according to the /var/log/messages) upgrading the two (64 & 32-bit) libgcc-packages an EXT3-error occurs and the root-partition gets remounted in read-only-mode. Consequently ALL following package upgrades throw errors saying this or that can't be done because he can't write to /etc, /usr but in the end yum says everything is OK. (Side info: /var is on a different partition, so it is still writeable) At reboot the machine wants a manual fsck which throws a lot of errors. Then the machine reboots with with a lot of error messages (basically because it can't find /lib64/libgcc_s.so.1 (nothing a symlink can't fix). After that I try to fix things by manually upgrading the libgcc-packages (otherwise yum won'T run). "rpm -q" for selected packages shows that the majority of the packages is still in 5.1-state. Trying to "yum upgrade" again fail because the machine can't find any servers (but network functionality seems OK) So I try to reboot. And now the really strange thing happens: A simple "rpm -q rpm" says that no rpm is installed. Rebuilding the rpm-database doesn't help. So I'm a bit stuck here with a machine that is in limbo. My questions: what could have been the cause for this (the machine was working OK before that). The only thing I feel a little guilty about was deinstalling the nvidia-kernel-driver and not reboot, but this can't f### up the file-system, can it? Any suggestions what I can do to get the machine into a normal state again (apart from reinstall from scratch)

CentOS 5.2 vs. Intel 82801 AC'97 Audio
by MHR 03 Jul '08

03 Jul '08

I have installed 5.2 on my work desktop and everything works perfectly EXCEPT the sound device. Here is the relevant lspci line: 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) I tried looking in Google (might have been a bad search), but all I could find was to add acpi=on to my boot line in grub.conf, and that didn't do any good. The volume control shows muted and I can't enable it. What am I missing? Thanks. mhr

command for brand of monitor
by Jerry Geis 03 Jul '08

Is there a linux command that would tell me what model of monitor is presently attached to my computer? Thought about automating different setups based on the monitor connected. X config files basically. Could be done with different kickstart files - but would like to not go there if I dont have to. Jerry

FF3 printing problem on Centos 4.x
by fred smith 03 Jul '08

03 Jul '08

I'm using Centos 4.x (fully up to date) on a system at work. I have also been using firefox 2 (directly from mozilla.org) on it for a long time, and it tends to work just fine. yesterday I installed the new FF3 release. It works fine too, with one exception: The print dialog shows no printers! The print button is greyed out! There actually four or five printers defined on the system, and all other apps find them fine, including FF2. So far no one has replied to my query on the mozillazine forums. Anyone here got any suggestions I can try? Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ------------------------ ---- Do you not know? Have you not heard?

Centos 5.2 upgrade - urlopen error unknown url type: media
by Robert Moskowitz 03 Jul '08

03 Jul '08

My first notebook upgrade: I repaired my old HP nc4010 (bought a new hinge on ebay) and realized this was the perfect way to test out the upgrade to 5.2 before doing it on my production notebook. First I updated to 'current' 5.1 (by current I mean I have not synced my 5.1 local repo since building my 5.2 repo). I had not used my nc4010 for a while and the kernel was at 2.6.18-53.1.13 (update took it to 1.21). Rebooted and system still working. I then pointed my CentOS-Base.repo to my 5.2 repo. I did a yum clean all then a yum update yum* rpm and below is what happened: ======================================================= [root@nc4010 yum.repos.d]# yum clean all Loading "installonlyn" plugin Cleaning up Everything [root@nc4010 yum.repos.d]# yum update yum* rpm Loading "installonlyn" plugin Setting up Update Process Setting up repositories http://linuxdownload.adobe.com/linux/i386/repodata/repomd.xml: [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')> Trying other mirror.

INIT 5 and system is gone
by Robert Moskowitz 03 Jul '08

03 Jul '08

I had been running a system on Centos 5.1 at INIT 3. I did the upgrade to Centos 5.2 with the aid of the powernowk8 patch. Previously I would VNC into the unit when I needed to do admin stuff with a GUI. Well I noticed that I was NOT getting GNOME via VNC since the upgrade (worked before just fine with 5.1). So I tried an INIT 5 from the command line (always worked before), but the system seemed to hang. Video was off. I rebooted, went to INITTAB and changed init to 5 and rebooted. Probably a tragic mistake. Now on boot, right after UDEV gets an OK, the screen goes blank and the drive stops turning. I tried booting with the 5.1 kernel, and same behaviour with the system blanking out and all load activity stopping after UDEV loads. So I am quite stuck at this point. Is there an option that I can edit into the kernel command at boot time to init in 3? And then what do I try? If I have to reload Centos, I have to pull the drive, put it into another system, install there, etc. Not my idea of a fun day....

laptop wireless--orinoco_cs, can it do WPA?
by fred smith 03 Jul '08

03 Jul '08

Hi! I'm messing about with an old Toshiba Tecra laptop. i've got wireless working well using NetworkManager and WEP. But I'm interested in finding out if it is possible to get WPA/TKIP or other WPA variants to work with that driver. According to dmesg, boottime diagnostics include: eth0: Hardware identity 0005:0004:0005:0000 eth0: Station identity 001f:0001:0008:000a eth0: firmware determined as Lucent/Agere 8.10 ... eth0 Station name "HERMES I" I've been googling a lot and most of what I see seems to indicate that there's no WPA support in that hardware, but that it may be possible to do WPA anyway if the drivers have the right set of patches. But so far I've not found anything definitive, especially not something that goes back far enough to be in a modestly old product like Centos 5.2. but anyway, if anyone knows anything about this I'd appreciate some hints. Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- "For him who is able to keep you from falling and to present you before his glorious presence without fault and with great joy--to the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore!

How did you configured the pppoe link? I have been using the adsl-setup command from the rp-pppoe package to configure the dsl link, it generates the ifcfg-ppp0 file on /etc/sysconfig/network/scripts with the values needed to bring the link up such as the username, network interface to use, etc. Also the adsl-setup command stores the username and password on the chap-secrets and pap-secrets files under /etc/ppp After the dsl is configured you can bring it up /down with the adsl-start adsl-stop commands. __________________________________________________ Correo Yahoo!

Ethernet poor performance
by Robert Moskowitz 02 Jul '08

02 Jul '08

I am attempting to build an IPv4/IPv6 router. I have put a 2nd ethernet card in a box. I have one Ethernet card attached to my network and the other to a switch with nothing else there just so the link comes up for testing. When I have the built-in Ethernet attached to my network, I get pings around 60ms. The other card, btw, does not have any IP addresses configed. When I switch the cards around, the addon card attached to my network, I get pings that alternate with one being ~1488ms and the next 488ms! This is regular. This is the 2nd card I have tried. The 1st one was getting ping times of 1900ms/900ms. I have played around with the IRQ for the 2nd card. The 1st card I tried I was limited to 9,10, or 11. The card I am using now allows 3, 4, or 7 (btw, I have disabled serial and parallel ports). Any Idea where I should look to fix this?

Want to _prevent_ upgrade to centos 5.2
by Ben Marsh 02 Jul '08

02 Jul '08

Hi, With the release of 5.2 "yum update" seems to be upgrading our computers from CentOS 5.1 to CentOS 5.2. I note from release notes for 5.2 that you are only supposed to get 5.2 if you type in "yum upgrade". On two seperate machines entering "yum update" has resulted in yum geting repo information for packages with versions that only exist in the base repository of centos 5.2. The following snippet shows the beginning of yum update on a x86_64 server. It has noticed python-2.4.3-21.el5.x86_64, ltrace-0.5-7.45svn.el5.x86_64 and system-config-securitylevel-tui.x86_64 0:1.6.29.1-2.1.el5 which are a CentOs 5.2 package. On a workstation yum update resulted in upgrade of firefox from 1.5 to 3.0-0 beta5. Can I stop this from happening? Ideally I would like to stay on a particulare version of CentOS eg 5.2 until we can do a controlled upgrade. Maybe we have the same problem as having stable specified in a debian sources.list where what is meant by stable changes when a new version of debian is released.

how to create an mpeg4 mimetype (OT)
by Phil Savoie 02 Jul '08

02 Jul '08

Hi All, I think this may be off topic, but since it's through centos 5.2, I'm not sure. Here is what I would like to do: I have created a web page for family to log into and view clips of my new niece. My camera saves these clips in mpeg4 format. What I would like to do is have the web clients click on the link and have either the clip pop up a save dialog or even better, start playing the clip. Right now if the link is clicked it starts downloading right away but the file looks like gibberish. I guess what I am seeing is the raw code. I think it's a mimetype thing but I'm not sure and if it is, how would I create the mimetype entry to do what I would like? Thanks in advance for any and all information received. Phil

Rebuild of kernel 2.6.9-67.0.20.EL failure
by John 02 Jul '08

02 Jul '08

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking for unpackaged file(s): /usr/lib/rpm/check-files /home/john/rpmbuild/tmp/kernel-2.6.9-67.0.20.EL-root RPM build errors: In my setup rebuilding the 2.6.9-67.0.15.EL kernel went ok Does anybody knows what I do miss or what is going wrong? For the curios: Why to recompile the kernel? I want to rebuild the kernel because I created a patch to decrease the kernel timer frequency from 1000 to 100 HZ. The CentOS4.6 kernel doesn't have the divider option available in CentOS5.2 This prevent timing problems and high CPU load in VMware ESX.

xen save/restore causes cron to hang
by Joe Pruett 02 Jul '08

02 Jul '08

i haven't found anything online to talk about this, so maybe i've got something odd going on here. i have my xen set up to save/restore on dom0 reboot. almost everything works fine, but cron on the guest os'es (everything is centos 5 x86_64) stop processing jobs. i'm guessing it is missing an alarm or something like that. anyone else see this?

Problem with nvidia-drv-x11 when upgrading to CentOS 5.2
by Bernhard Gschaider 02 Jul '08

02 Jul '08

Hi! I know that the nvidia-drv-x11-package is from RPMForge, but I thought I might mention it here. I have a machine with a NVidia-card and because of the ease of use I use the rpmforge-package for that. After upgrading the problem was that during rebooting as soon as the machine hit the RHGB (which implicitly uses that driver) the machine froze. I booted into the old kernel removed rhgb, rebooted. Now the machine froze when starting X. Same procedure: Old Kernel. Remove nvidia-drv-x11. Reboot into the new kernel and reinstall nvidia-drv-x11. After a reboot everything works as it used to. The cause of the problem could have been (sorry, I didn't do any thorough forensic) that the nvidia.ko that was used in the new kernel was a symbolic link from the "weak-updates"-directory into the old kernel "extra"-directory. Is it possible that this only works inside of kernels with the same x in CentOS 5.x ? For the other machines I am upgrading I plan to 1. deinstall nvidia-x11-drv 2. do a regular "yum upgrade" 3. reinstall nvidia-x11-drv after reboot Is there any better way to do it? Bernhard PS: the main purpose of this message is to alert others to this problem, not to get an answer, although that would be nice

is CentOS an LSB certified product?
by Nicholas 02 Jul '08

02 Jul '08

Hi all, Would anyone know if CentOS 4 and 5 is LSB certified? I have not found any info on RH being LSB certified either. Is RH also LSB certified? In case you need to know, I am compiling a list of LSB certified Linux just for comparison as to who would want to be LSB certified. Just to see if it matters to ppl if it matters to be certified. --- Join OSCC MAMPU Mailing Lists http://lists.oscc.org.my/mailman/listinfo/oscc-discuss

'sealert', the client portion of 'setroubleshoot', runs from the command line as well as under 'x'. Check the man page for sealert. "sealert may also be run in command line mode. The two most useful command line options are -l to "lookup" an alert ID and -a to "analyze" a log file. When setroubleshootd generates a new alert it assigns it a local ID and writes this as a syslog message. The -l lookup option may then be used to retrieve the alert from the setroubleshootd alert database and write it to stdout. This is most useful when setroubleshootd is being run on a headless system without the GUI desktop alert facility." Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

extract MIME attachments from 700MB imap folder
by Ray Leventhal 02 Jul '08

02 Jul '08

Hi all, Issue: I've been tasked with extracting a bunch of MIME attachments (M$Word docs) from emails which have been stored in an imap folder in /home/<username>/mail/<imap foldername>. As the subject states, the imap folder is about 700MB. Googling suggested that munpack might do the trick, but as it is intended only for one message at a time, it outputs the first attachment found, then exits gracefully. Further searches seemed to talk about mimedump, so I yum installed perl-MIME-tools.noarch from rpmforge as mimedump this was needed, and includes mimedump. I've read the man page, but am wholly unclear as to: 1) will this do the trick for me 2) are there other known tools which might be recommended Thanks in advance, -Ray System runs CentOS 5.1, not updated since April, but it is not connected to the internet (I do bring it online to install packages as needed); I will do a complete upgrade before the end of this month.

RE: [CentOS] African IP addresses list
by Tony Wicks 02 Jul '08

02 Jul '08

> I would like to add something, as a South African citizen. South Africa, is NOT part of Africa for that matter, it's a republic on it's own. It's almost like saying "Let's ban America, cause someone in Mexico spammed me". South Africa, which is on the 196/8 range does a LOT of business overseas in many countries, and I do want to warn that you could loose a lot of good business due to this practice. Most of the fraud you experience could come from Nigeria, or one of the other central & western Africa countries. To ban a whole continent because of problems some countries cause could be problematic. For that matter is China a different country from Russia, from Switzerland, even though they share the same land mass -- I need to put my 2c in here. I'm from New Zealand, we are a first world democratic country (the first in the worlds to give the vote to ALL adults I may mention). I have had the misfortune many of times of being unable to transact business because people from the US in their ignorance think, that New Zealand, isn't that part of Australia, which is right next to Asia, can't do business with those Asians, they will rip me off. Now sometimes people from the US have asked me why people in the other parts of the world get a bit annoyed at the "the only country that is free and true if the good old US of A" attitude, and well here you go as an example. Lets ban all of Africa because someone from Nigeria is a scammer. Africa is a pretty big place, and you know what, I've met many South Africans that are real nice (even employed a few). I've always been someone who defends America when people run it down, but it is a two way street, don't treat a whole country as criminals because you don’t know the difference between one side of a continent from another, its kind of insulting you know. And some day you might well need the rest of us, you never know.

EPIA-M board for Centos
by Robert Moskowitz 02 Jul '08

02 Jul '08

Is there any problems using this board? I have a dead board in a Book-PC (board size 10.5"x6") so am looking for a new board. Actually I want 2 LAN ports. 'Router' boards with enough umph to run Centos are expensive. I can pick up a VIA epia-m with 512Mb memory for $70 including shipping, so this is rather attractive option. I do have a 100Mb low-height PCI board that I can use. Fitting the board and card into the Book-PC box will be a bit of DIY engineering, but other than maybe loosing the front USB ports (big deal in the case), looks manageable. thanks for any experience/advise.

African IP addresses list
by Matt Arnilo S. Baluyos (Mailing Lists) 01 Jul '08

01 Jul '08

Hi all, I am trying to block all IP addresses from Africa due to a high rate of fraudulent orders coming from them. I have some found some websites that can generate a range of IP addresses. However, you would have to enter the ranges by country. I can use those perhaps but that would mean I would have to get the ranges for each country one by one. Has anyone here a list of addresses from Africa already? It would definitely be a time saver for me. My firewall uses IP blocking by CIDR. Thanks, Matt -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

Missing update announcements for C4 i386 / x86_64

Hi, the latest updates for perl, xorg-x11, net-snmp, openoffice.org for C4 were announced for the ia64 and s390(x) archs, but not for i386 and x86_64 altough they are available on the updates mirrors. Also, what is the policy for announcements of updates that occurred after the C5.2 release? I see them on the update mirrors. Shouldn't these update be also announced independently from the C5.2 release announcement? Best regards, Bernd.

Configuring sendmail in a corporate environment
by Alfred von Campe 01 Jul '08

01 Jul '08

I have a stock CentOS 5 system as far as email (sendmail) is concerned that is on our corporate LAN. I am not trying to set up a mail server; I merely want our CentOS systems to be able to send out emails. This works as long as the recipient's domain is our local domain. Any email send to recipients that are not in our local domain get stuck in the queue: # mailq /var/spool/mqueue (2 requests) -----Q-ID----- --Size-- -----Q-Time----- ------------Sender/ Recipient----------- m61D6wC1029257 16 Tue Jul 1 09:06 <XXXX(a)XXXX.XXXX.com> (Deferred: Connection timed out with mx2.emailsrvr.com.) <alfred(a)von-campe.com> It appears that our firewall is not allowing connection to outside MX hosts. I think I need to configure sendmail to forward emails to our local smtp host, but I am not sure how to do that. Alfred

01 Jul '08

All, I have a fresh CentOS 5.2 server that I am just starting to customize, it is very close to stock. This morning I ran yum update: ============================================================================= Installing: kernel-xen i686 2.6.18-92.1.6.el5 updates 15 M Updating: samba i386 3.0.28-1.el5_2.1 updates 16 M samba-client i386 3.0.28-1.el5_2.1 updates 4.9 M samba-common i386 3.0.28-1.el5_2.1 updates 8.7 M After rebooting, Samba would not start, running 'service smb start' simply hangs forever, nothing in the logs I could find and I could see from ps that smbd was never forking to release the start script. I discovered that if I boot using the previous kernel 2.6.18-92.1.1.el5xen all is well. I did try regressing samba by uninstalling and then installing disabling the updates repo to no avail, the older version (1.1) of Samba was installed when I tried booting the older kernel, which did work, as well as the updated version (1.6).
