disable auto-negotiation gigabit ethernet
by sebastian 20 Mar '12

20 Mar '12

I can not disable the auto-negotiation (eth1) on my centos 6.2 via ethtool or /etc/sysconfig/network-scripts/ifcfg-eth1 the eth1 is a private network on a cheap gigabit-switch (under controll from a serverhoster). sometime the ethernet-card lost the "speed" and "duplex" information and change it to "unknown". i can only fix this with a network-restart (or ifup/ifdown). now i will disable the autonegotiation - but i does not work. thanks sebastian

ABRT interpretation / guidance needed
by Jeff Boyce 20 Mar '12

20 Mar '12

Greetings - I have a Centos 6 box fully updated that intermittently sends me an "[abrt] full crash report" email. I am not familiar with these at all and in my limited google search have not found good information to interpret this information. The most recent (and the most frequent one) is listed below, also I have listed the lines from /var/log/messages that correspond to it. This box is an Dell Optiplex GX520 that I am temporarily using as a location to store some backup information while I put together a more permanant backup solution. The box is headless with Webmin installed to manage it. It continues running when these occur, and I have not noticed any detrimental effects. I am trying to understand the primary issue these messages are trying to tell me so that I can do a little more research and figure out what I need to do about it (if anything). My limited understanding reading this information is that Webmin is running a cron job that references rpm, and that something in rpm is causing a problem with the kernel? Thanks for any interpretation, or good reading references anyone can provide. /var/log/messages Mar 19 15:07:10 tempbackup kernel: rpm[19022]: segfault at 8b96000 ip 008a3fcc sp bfe251e0 error 4 in libc-2.12.so[837000+189000] Mar 19 15:07:11 tempbackup abrt[19023]: saved core dump of pid 19022 (/bin/rpm) to /var/spool/abrt/ccpp-2012-03-19-15:07:10-19022.new/coredump (3825664 bytes) Mar 19 15:07:11 tempbackup abrtd: Directory 'ccpp-2012-03-19-15:07:10-19022' creation detected Mar 19 15:07:11 tempbackup abrtd: Freeing read locks for locker 0x167a: 19022/3079309088 Mar 19 15:07:11 tempbackup abrtd: Freeing read locks for locker 0x167b: 19022/3079309088 Mar 19 15:07:11 tempbackup abrtd: Freeing read locks for locker 0x167c: 19022/3079309088 Mar 19 15:07:20 tempbackup abrtd: Sending an email...

Where Did All The Noise Go?
by Eugene Poole 20 Mar '12

20 Mar '12

OK, I've got 2 machines running CentOS. One running CentOS x86_64 6.2 and the other running CentOS x86_64 5.8. At some upgrade point I've lost all sound using Firefox and Thunderbird with my Gnome desktop. When I bring up 'System', 'Preferences', 'Sound' and go to the hardware tab and test the speakers, they are working. Any ideas on how to get the sound back? TIA, Gene + It's impossible for everything to be true at the same time +

nfs client issues since updating from 5.7 to 5.8 on the NFS server
by aurfalien 19 Mar '12

19 Mar '12

Hi all, Wondering if any one has seen odd NFS client behavior with a 5.8 NFS server? While by Nix and OSX clients are fine, my Windows clients are acting up. I can no longer mount any NFS share from a 5.8 NFS server box on my Winblowz clients. I'll keep digging around but nothing has changed on the client end. Since my NFS server OS has changed, I'm assuming a client adjustment is needed. Also, does any one know of a way to max out verbosity on my NFS server? Things are showing (failed and successful client NFS mount attempts) in /var/log/messages but I've a feeling that something is missing. Thanks in advance, - aurf

testing a udp socket with netcat
by Arif Hossain 19 Mar '12

19 Mar '12

i've this udp daemon which is waiting for an incoming udp datagram. now i want test this daemon for random garbage to test how it behaves. My udp daemon is running because its shows on netstat. problem is if i issue following command for putting udp datagram : $nc -uvvz <host> <port> it does not output any thing. i have straced the udp daemon. which does not returns from recv() call. my goal is to put arbitrary data on the udp socket by netcat. i do not have any experience regarding netcat so i'm asking if anyone can help me out with this. thanks in advance. -- "You have a voice" ----The King's Speech Public Key : $ gpg --keyserver keyserver.ubuntu.com --recv-key C88CFC23

Odd thing with Realtek Ethernet card
by Ken Smith 18 Mar '12

18 Mar '12

Hi all, I swapped a Realtek 8139 100M Net Card for a Realtek 8169 Gig Net card in a Centos 5.6 system. After reconfiguring the network settings I find that on boot up the 8169 interface does not start. The startup script says something like "The 8169 is not available..." ifconfig -a shows a device with the right mac address called __tmpsomethingorother I can get it going if I remod the r8169 driver and load it again. Then ifup eth1 works. There's also a Marvell 88E8056 on the motherboard. /var/log/messages shows the 8169 as eth0 and the Marvell as eth1 but when the network is finally up they are the other way round. ifcfg-eth0 has the mac address of the Marvell in it and ifcfg-eth1 doesn't have a mac address in it. Should I wipe those scripts and start again? I've put a nasty bodge in rc.local for the moment to make the startup work.

Fail2ban problem
by Timothy Murphy 18 Mar '12

18 Mar '12

If there is a serious power failure, eg during an electric storm, and the internet goes down then my CentOS-6.2 server seems to take an inordinate time, maybe forever, to get past fail2ban. It is as though there is an extremely long - maybe an hour - timeout if fail2ban cannot connect to the internet. (I usually stop the machine with the power-button, re-boot into a different OS (Fedora) and chkconfig off fail2ban.) This only occurs once or twice a year, so I don't worry about it much; but I was wondering if there is a timeout that I can change somewhere in the fail2ban setup? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

CentOS 5 Testing repo
by Spiro Harvey 18 Mar '12

18 Mar '12

We were using the CentOS 5 testing repo on dev.centos.org to update our webservers' PHP to 5.2. However, we've just tried building a new machine lately and found that the repo seems to be empty. Is this a temporary fault, or has it gone away now that CentOS 6 is out? If it has gone away, where can I grab PHP 5.2 packages from? Thanks. -- Spiro Harvey Knossos Networks Ltd (04) 460-2531 : (021) 295-1923 www.knossos.net.nz
