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?

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.

iptables: forwarding on internal device

Good Evening, I am trying to forward packages on an internal device using iptables: /sbin/iptables -A FORWARD -i eth0 -o eth0 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT but the packages are still blocked, e.g.: Feb 6 20:58:28 firewall kernel: DROP-TCP IN=eth0 OUT=eth0 SRC=192.168.100.177 DST=172.28.2.184 LEN=40 TOS=0x00 PREC=0x00 TTL=127 ID=16609 PROTO=TCP SPT=7166 DPT=3590 WINDOW=0 RES=0x00 ACK RST URGP=0 net.ipv4.ip_forward = 1 is set, too. Best Regards Marcus

tinydns/djbdns opinion poll
by Jake 10 Feb '09

10 Feb '09

Good morning: We're about to start moving our public DNS to in-house managed servers. My first thought was "Linux + BIND" and we're done. Someone in another business unit's IT dept. has suggested tinydns be used. >From what I could find, it looks like this software hasn't really had any community drive behind it in a while. The latest RPMs on rpmforge are for red hat 6 and red hat 7. I very much dislike the idea of compiling my own because of all the overhead associated with making sure the system stays up-to-date and so on so this really puts me off already. Does anyone have an opinion on this software? It seems to have some strong virtues but maybe not enough to justify using it over BIND just because any Linux admin we hire could be expected to know BIND. Thanks for your time, -- Jake Paulus JakePaulus(a)gmail.com

Scripting Oddity
by David G. Miller 10 Feb '09

10 Feb '09

I've been playing around with qemu and wanted to make the guest OS instance visible on my network. This meant getting bridging and tun/tap working. After getting things working by pasting command from the CentOS wiki article plus adding a few enhancements, I decided to capture the process in a shell script that would be suitable for a user in the sudoers file to fire off. Not sure why (which is why I'm posting this) but I couldn't get the same result from the shell script as I got from pasting commands onto the command line or using the shell history. After a lot of very tedious debugging, I finally got the script to work by adding a couple of short sleeps at selected locations. The script now looks like: cat upBridge.sh #!/bin/bash # # Script for setting up a bridge accessible by a qemu VM. # # First, make sure we're starting with a clean slate. /usr/bin/sudo /sbin/rmmod bridge /usr/bin/sudo /sbin/rmmod tun /usr/bin/sudo /sbin/service network restart # # Grab the IP address of the given interface so we can restore it later. # oldIP=`/sbin/ifconfig $1 | /bin/grep 'inet addr' | /usr/bin/awk -F \: '{print substr($2,0,index($2, " ")) ; }'` echo "$1 currently has IP address $oldIP" # # Create the bridge. # /usr/bin/sudo /usr/sbin/brctl addbr br0 /usr/bin/sudo /sbin/ifconfig $1 0.0.0.0 sleep 2 /usr/bin/sudo /usr/sbin/brctl addif br0 $1 # # Stop any dhclient still running. # /usr/bin/sudo /usr/bin/killall dhclient # # Get and IP address and routing information for the bridge # /usr/bin/sudo /sbin/dhclient br0 # # Make sure the tun module is loaded, assign it to our user and bring it up. # /usr/bin/sudo /sbin/modprobe tun echo "Did tun load?" lsmod | grep tun /usr/bin/sudo /usr/sbin/tunctl -b -u $USER sleep 2 /usr/bin/sudo /sbin/ifconfig tap0 up # # Connect the bridge and the tap. # /usr/bin/sudo /usr/sbin/brctl addif br0 tap0 /usr/bin/sudo /bin/chown $USER:users /dev/net/tun /usr/bin/sudo /sbin/iptables -I RH-Firewall-1-INPUT -i br0 -j ACCEPT # # restore the IP address of our "normal" interface. # /usr/bin/sudo /sbin/ifconfig $1 $oldIP So, my question is, why do I need to have a short sleep in these two locations in my script? Without a sleep after the "ifconfig eth0 0.0.0.0", eth0 retains its original IP address instead of having no address. The qemu guest VM still functions correctly but the host system loses connectivity. Likewise, without a sleep after the tunctl command, the device /dev/net/tun isn't present when the next command executes. With the sleeps the script executes as expected and sets up the bridge. Without the sleeps the script fails. Oh yeah. There's another script called downBridge.sh that undoes the bridge if anyone is interested. Cheers, Dave -- Politics, n.
