Possible CentsOS licensing issue
by Puneet Goel 12 Feb '09

12 Feb '09

Dear Friends, I have few questions. 1. I have a device on which I have installed CentOS 5.2 as an operating system. Now I want to sell this device. Will there be any issue ? points to keep in mind: a. There are no changes in OS. (it is just a stripped down image of original OS) b. I have installed few generic user space applications of my own installed in that OS. I do not want to violate GPL or any other licenses. That's why to make sure I want to confim from you folks. Thanks Puneet

5.2 x86_64 DVD
by Ward.P.Fontenot＠wellsfargo.com 12 Feb '09

12 Feb '09

I've pulled this down with Firefox, wget, a bittorrent client and an ftp client using Windows as well as Linux hosts. Is something wrong with the distributed DVD image? It has failed an MD5 check every time I've pulled it down.

rt_cache leak in 2.6.18
by Hector Herrera 12 Feb '09

12 Feb '09

Hello, This is a CentOS 5.2 box configured as a router for a network handling about 200-300 Mbps, routing traffic to/from the internet for about 6,000 IPs. After about 2-3 days, the kernel complains about "dst cache overflow" and even thought it hasn't crashed, the network is un-responsive. All IP forwarding stops and the server cannot be reached from any network interfaces. After diagnosing the issue, it appears that there is a rt_cache leak in the kernel. At 5 minute intervals I collect the following two values: `/sbin/ip -o route ls cache | wc -l` `grep ip_dst_cache /proc/slabinfo | awk -F' ' '{ print $2; }'` The first value represents the number of cached routes in the network stack. The second value represents the number of cached route objects the kernel has allocated. After collecting the data for 8 hours, I have seen the cached routes count remain fairly constant, but the number of cached route objects increase from about 220,000 objects to 410,000 objects. The cached routes count remains between 4,000 and 8,000 routes. I posted a pretty graph at http://www.pier-pro.com/ip_dst_cache_leak.png (the blue line is the value of ip_dst_cache, the green value represents the count of cached routes). Once the ip_dst_cache value reaches the value of /proc/sys/net/ipv4/route/max_size then the network fails and the kernel complains about 'dst cache overflow' whenever a packet arrives. The only solution at that point is to perform a reboot. Flushing the routing tables by `echo 1 > /proc/sys/net/ipv4/route/flush` only clears the cached routes, however the value of ip_dst_cache does not change. According to http://linux.derkeiler.com/Mailing-Lists/Fedora/2005-07/1175.html this is a known bug that was fixed in 2.6.11, however, I'm running 2.6.18 (as updated with `yum update`) I downloaded the kernel sources, and indeed, the kernel source contains the bug fix in the above article. Therefore ... I'm at a loss as to where to go from here. Certainly rebooting the server every day is not an option, and increasing the max_size will just delay it. Suggestions? Thank you, Hector

smartd and 3ware 9xxx configs
by Jim Perrin 11 Feb '09

11 Feb '09

I'm looking to do a bit more monitoring of my 3ware 9550 with smartd, and wanted to see what others were doing with smart for monitoring 3ware hardware. Do you have the smartd.conf configured to test, or simply monitor health status? Are you monitoring the drive as centos sees it (/dev/sdX) or are you using the 3ware /dev/twaX for monitoring? Opinions and discussions are welcome :-P -- During times of universal deceit, telling the truth becomes a revolutionary act. George Orwell

Problems with mysql multi-master after update.
by Alessandro Ren 11 Feb '09

11 Feb '09

Hello, after I updated from mysql-5.0.22 CentOS 5.0 to mysqld-5.0.45 in CentOS 5.2, mysql looses master-slave sync after one node reboots. I've noticed that the slave doest not respect the informantion on master.info, instead, it tries to read the informantion from the master server file inc-index.index. Let me give a example, the master is alredy on incremental.000006 and the slave in synced, the master.info in the slave server is showing is is reading de incremental.000006, but in the master inc-index.index all 6 files are listed, from 1 to 6. The file 1 to 5 were already deleted in a cleaning process as thay were alread synced with the slave. After the reboot, the slave tries to find the file incremental.000001 on the master and this causes the problem. In 5.0.22 this would not happen, this does not happen as I have servers running this version and after the reboot, it starts syncing on the right incremental. Any idea? Tks.

What is the System Event Log?
by Timothy Murphy 11 Feb '09

11 Feb '09

My Dell PowerEdge T105 running Centos-5.2 has started crashing fairly often (3 times in the last 2 hours). The message on the screen tells me to look at the System Event Log. Is this just /var/log/messages ? I didn't see anything helpful there. As far as I could see, the last messages before the crash were about samba, which is running on the machine. Has anyone had such problems with Samba? I've stopped the smb service to see if this improves matters. I'm running a standard updated system. I looked at smartctl but this did not suggest that there was anything wrong with the 2 SATA disks. Incidentally, wouldn't it be a good idea for /var/log/messages* to start a new file when booting?

by Fajar Priyanto 11 Feb '09

11 Feb '09

Hi all, I have a strange situation. I have a machine connected to an AT&T VPN. Sometimes the VPN gets disconnected, so I create a cronjob to restart the VPN client when it happens: Problem is: sshd seem doesn't want to bind to tun0. I restart ssh, network, no good. Anyone has any clue? So strange. Thank you.
