Re: [CentOS] real SATA RAID
As many people have stated in this thread, 3ware and Areca make some good hardware RAID solutions. Software RAID using mdadm works too, quite well, I might add. I was one of those people who stayed away from software RAID in linux, thinking it was too complicated and difficult, I was wrong. It's dead easy to do, and expanding your disks can be done on the fly (if you have a SATA controller that supports hotplugging as many these days do.) Perhaps the best thing about software RAID, in my opinion, is that it's light enough on the machine that a PIII server can be reading/writing to the array at 10MB/s. Now you might say, 10MB/s, who cares? That's small stuff. But, when that's the load the network infrastructure at this location was designed to handle, you don't need anything higher performance. Just my two cents. -Hal Christopher Chan wrote: Paolo Supino wrote: Hi Last week I had a lengthy thread in which someone indicated the my SIL card is a FRAID (don't know if F stands for the F word or Fake, though it doesn't really matter).

[CentOS] Problems with mysql multi-master after update.
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.06 and the slave in synced, the master.info in the slave server is showing is is reading de incremental.06, 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.01 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?

We use tinydns+dnscache almost exclusively (it's not good if you need to play 2ndary for a true BIND) and are very happy with it. We have been using djbdns for years with excellent results, and user very few non-standard patches (mainly a hack to dnscache to allow it to respond to the world on one of our servers that we allowed customers to use in the mid '90s, and can't change). We are secondaries for a few hundred BIND domains, and have no problems with that using djb tcpclient axfr-get to pull the data from these under control of a cron job. We are also provide secondary DNS for many of our customer's sites which run djbdns, and they simply use rsync to copy their zone files to our primary server. We use the rbldns daemon extensively to handle DNSRBLs. The data formats for djbdns are quite simple, particularly compared to the ugly kludge of BIND. Setting up forward and reverse DNS for a host for which one is authoritative for the in-addr address requires a single line, at a minimum: =fqdn:ipaddress: The startup times are essentially zero, as are updates to remote servers using rsync to copy the tinydns and rbldns data files to our secondary servers. The version we run on all our Linux systems has been hacked into SRPMS for the OpenPKG portable package management system, and we run it on various Linux distributions, FreeBSD, and OS X. I don't remember exactly when we started using djbdns, but it was at least 8 years ago. Other than a simple hack I did years ago to have dnscache ignore CVS and RCS directories, it has been dead solid with zero problems.

We are secondaries for a few hundred BIND domains, and have no problems with that using djb tcpclient axfr-get to pull the data from these under control of a cron job. We are also provide secondary DNS for many of our customer's sites which run djbdns, and they simply use rsync to copy their zone files to our primary server. We use the rbldns daemon extensively to handle DNSRBLs. The data formats for djbdns are quite simple, particularly compared to the ugly kludge of BIND. Setting up forward and reverse DNS for a host for which one is authoritative for the in-addr address requires a single line, at a minimum: =fqdn:ipaddress: The startup times are essentially zero, as are updates to remote servers using rsync to copy the tinydns and rbldns data files to our secondary servers. The version we run on all our Linux systems has been hacked into SRPMS for the OpenPKG portable package management system, and we run it on various Linux distributions, FreeBSD, and OS X. I don't remember exactly when we started using djbdns, but it was at least 8 years ago. Other than a simple hack I did years ago to have dnscache ignore CVS and RCS directories, it has been dead solid with zero problems.

Re: [CentOS] iptables: forwarding on internal device
Dear Michael, The system you are trying to forward with has at least two nics on different networks? However you are trying to forward between aliases on one nic that is located on your internal network? And the other nic connects to a DMZ or gateway network? This system is not a decicated routing/forwarding system but runs other services for network clients/servers that connect to it? Yes, that's true. We are routing between two internal networks on that box (migrating to core switch, soon). But that's not the problem. I just wonder why the packages are dropped (as it worked correctly on the Slackware box, before - using the same ruleset) Btw. it seems that 'service iptables save' fits to activate all other rulesets. And it is NOT necessary to define input and output rules for forwarding on an internal device.

Re: [CentOS] tinydns/djbdns opinion poll
Jake wrote: 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. tinydns supports large zone/record updates on the fly...in comparison with bind which will stop answering while it is loading up zones. The caveat however is that you need GOOD disk i/o if you have a lot of records because tinydns achieves that due to use a cdb database whereas BIND will stick them all in memory. So if you are constantly updating zones, I would suggest tinydns as the entire process can be automated and the source for the cdb database stored in a nice sql database with a nice frontend, script plugin/api for whatever you imagine. If you don't have very dynamic stuff and you do not need to constantly rebuild zones, BIND should be better I suppose especially if you are in an environment where a lot of zones share the same data (ns, mx,...) thanks to INCLUDE. As for making sure the system stays up-to-date, you do not have to worry about djbdns and daemontools...they are pretty much set in stone now excpet for maybe some patches that you might want (it's public domain so just roll your own if you do need them patches). All you have to worry about is installing on new systems. It is literally compile once and forget. Zero overhead. Oh, may I point out that there are no security issues with djbdns whereas BIND has a history of problems even until recently. 'slaves' can be updated with by rsyncing the cdb database over so there is no room for human error with respects to dns server configuration whether it is leaving recursive on or whatever. Interesting that any Linux admin you can hire will know BIND. I find that not to be the case over here in Hong Kong.

I have never come across issues with any 3ware boards hardware-wise. I suppose you have an opinion about Adaptec 2405 and its other new lines of real hardware cards? Software RAID using mdadm works too, quite well, I might add. I was one of those people who stayed away from software RAID in linux, thinking it was too complicated and difficult, I was wrong. It's dead easy to do, and expanding your disks can be done on the fly (if you have a SATA controller that supports hotplugging as many these days do.) Perhaps the best thing about software RAID, in my opinion, is that it's light enough on the machine that a PIII server can be reading/writing to the array at 10MB/s. The guy asked for real hardware raid card suggestions. You can preach all you like about software raid, there are cases where hardware raid cards with sufficient resources will offer better value. Now you might say, 10MB/s, who cares? That's small stuff. But, when that's the load the network infrastructure at this location was designed to handle, you don't need anything higher performance. I don't know about you but where I work, one of the first infrastructure issues I dealt with was upgrading from Fast Ethernet to Gigabit. The teachers all appreciate their logins running faster, the loading of their multi-megabyte powerpoints being faster, their on-disk gallery of school trip pictures loading faster, etc. In this age of files being megabytes in size even hundreds, a ten megabyte/sec network does not fly anymore. BTW, I use raidz so as I do not need to hit anything over 100MB yet and 2 TB storage is sufficient for the moment. Good luck trying to get a controller card that has 8 ports or more without even a fakeraid bios. I am so happy that there are many motherboards that come with 4 SATA ports and work under Linux. But find one that also has a PCIe 4x slot is a pain in the neck.

[CentOS] process accounting - track PIDs
Hello -- I've done some searching but haven't come up with much yet, I was wondering if there was a way to track PID creation and what command was assigned to a PID? I am trying to track down a locking issue with NFS/NLM where the client PID that initiates the unlock request is not the same PID that initiates the lock request. Even with running ps auxww in a while true loop I cannot seem to capture the PID it comes/goes too fast. I can see the PID right after the one specified, but not the one I want. I tried a couple things I found for the audit system: auditctl -a entry,always -S fork -S vfork -S clone auditctl -a entry,always -S brk -F 'a0=0' auditctl -a task,always auditctl -a exit,always And none of them were able to detect the PID that was created. Another way to approach this is perhaps NLM debugging on the linux client side but I haven't had any luck tracking down useful debugging info on the client side. I saw one post mentioning a kernel patch is needed and it may make it into RHEL 5.3, though this is 4.4, so maybe it is not possible. any ideas? thanks nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Scripting Oddity
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

Really nasty of them to bother with dumping SM prefs. That the worst damage I've found so far after getting stuff cleaned up or sort of cleaned up.

I do it differently for my UML instances, but I don't see why this shouldn't
work with qemu as well.
Firstly I have a simple boot script that creates the bridge and binds the real
interface (eth1 in my case) to the bridge.
#!/bin/sh
# BRIDGE Create br0 with just eth1 bound
#
# chkconfig: 2345 09 91
# description: Activates br0
case $1 in
start) touch /var/lock/subsys/BRIDGE
/sbin/ifconfig eth1 0.0.0.0 promisc up
/usr/sbin/brctl addbr br0
/usr/sbin/brctl stp br0 off
/usr/sbin/brctl setfd br0 1
/usr/sbin/brctl sethello br0 1
/usr/sbin/brctl addif br0 eth1
;;
stop)
# Do nothing
rm -f /var/lock/subsys/BRIDGE
;;
status)
echo $Configured devices:
/usr/sbin/brctl show
;;
restart|reload)
# No nothing
;;
*)
echo $Usage: $0 {start|stop|restart|reload|status}
exit 1
esac
exit 0
Then in my /etc/sysconfig/network-scripts area, I have br0 with the IP
address I want. In my case, it's static
% cat /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
ONBOOT=yes
BOOTPROTO=static
BROADCAST=10.0.0.255
IPADDR=10.0.0.136
NETMASK=255.255.255.0
NETWORK=10.0.0.0
TYPE=Ethernet
So what this means is that at bootup time the system will come up with
br0 connected to the network and everything runs as normal. Basically, at
this stage you can treat your machine as if 'br0' is the network device.
Now adding a new tap device to the bridge would be as simple as
int=`tunctl -b -t $TAPNAME`
ifconfig $int 0.0.0.0 promisc up
brctl addif br0 $int
Now the new tap device is connected to the external network and the other
side of the tap (the guest) can get an external IP address (eg via dhcp,
or static) as normal.
On the host, only br0 shows as an IP address. The physical device (eth1)
and added taps don't have an address when viewed with ifconfig.
