[CentOS] IP aliases of CentOS Guests not accessible running 2.6.18-164.el5xen
Hi all, First of all I am posting this on two lists for a reason, because the issue being reported by me could be because of a change delivered by a Kernel update or due to Xen. I have recently managed to update all Xen Guest domains running CentOS 5.3 to the latest bunch of updates + Kernel. My Xen host also runs the same CentOS 5.3 updated to all recent packages. The Guest images in concern had IP aliases assigned to them. Everything worked until I ran the updates and restarted. Since I have restarted the aliased IP addresses are no longer accessible from the outside world, they can still be accessed from all machines (guest virtual machines) in the subnet (ping, services like http). I have removed all firewall rules to test if that would have effected it without any change (any the fact that I can access them within the subnet proves its not the firewall). Is there anything special I have to do to enable aliasing? May be this is a Xen issue? I am suspecting the Xen host, but not sure how to go about proving this. Any information would be greatly appreciated. My Guests do run fail2ban (delivered via atrpms) and iptables (allowing only HTTP, HTTPS and SSH) connections. PS for obvious reasons I am not posting IP addresses and routes etc first up, I can make that information available if required. -- "The secret impresses no-one, the trick you use it for is everything" - Alfred Borden (The Prestiege) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] mounting images created using dd that contain two partitions
Thanks a lot for that, I will give it a go. I am trying to get another machine with CentOS 5.3 so I can use that to perform the rescue operations. Did you see my post on the virtualisation list? If so do you have any thoughts on that post?

[CentOS] mounting images created using dd that contain two partitions
Hi all, I am trying to mount images that I previously created with dd and the images have two partitions (swap and LVM). I use these images to house data for my Xen Guests. For some reason (possibly Kernel conflicts for paravirtualized domains) I am unable to boot my Guest images. Failing which I would like to mount the disk images and atleast get my data out of them. dd -o loop server.img /media/diskimage asks me to provide a file system. How can I mount these images? I have been Googling around for this and have failed to find and answer, can someone please point me in the right direction.

[CentOS] php-mcrypt from c5-testing is the wrong version
Hello all, I am using the c5-testing repo to fetch PHP 5.2.6 and related libraries, required for the LAMP apps that I want to use. php-mcrypt still seems to come from the extras repo and is version 5.1.6 and the php binary doesn't load this module. Any ideas on howto get php-mcrypt 5.2.6?

[CentOS] Two sets of Heartbeat HTTPD clusters on same subnet
Hi all, I am new to Hearbeat so please be kind :) I also posted this on Linux-HA lists with no responses so I posted it here. I have successfully configure two machines to use heartbeat to cluster httpd. The two nodes are called etk-1 and etk-2. I am trying to configure another two machines to act as a separate cluster (on the same IP subnet). These two nodes are called radu-1 and radu-2. Obviously being a broadcast protocol radu-1 and radu-2 get these messages from etk-1 and I can't seem to get radu-1 and radu-2 to cluster (mostly probably because they are not getting the messages from the right nodes). Should I just change the name of the test, if I do that I get heaps of WARNING log messages. Is it possible to have two sets of clusters in the one IP subnet? If yes what do I have to change so these clusters don't send messages to the wrong nodes. heartbeat[3745]: 2009/03/30_04:48:02 ERROR: process_status_message: bad node [etk-1] in message heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG: Dumping message with 10 fields heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[0] : [t=NS_ackmsg] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[1] : [dest= etk-2] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[2] : [ackseq=1a9601] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[3] : [(1)destuuid=0xdf38de8(37 28)] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[4] : [src= etk-1] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[5] : [(1)srcuuid=0xdf39248(36 27)] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[6] : [hg=499a2a65] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[7] : [ts=49cfb452] heartbeat[3745]: 2009/03/30_04:48:02 ERROR: MSG[8] : [ttl=3] -- "The secret impresses no-one, the trick you use it for is everything" - Alfred Borden (The Prestiege) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Fail2Ban

[CentOS] Linux HA or Heartbeat IP address question
Hi all, I am following the guide on HowToForge to get Heartbeat going for two Apache web servers (http://www.howtoforge.com/high_availability_heartbeat_centos), a quick question for anyone who might have a similar setup. Do I have to assign the service IP to either of the NICs or does Heartbeat do that automagically?

[CentOS] CentOS 5 Xen Dom0 Kernel doesn't see CDROM
Hi all, I have successfully got Xen virtualisation configured with CentOS 4 (64bit). However now that I am using the Xen Kernel my Dom0 doesn't seem to see the DVDROM device. Is this intentional in the kernel? Is there anything (apart from compiling my own kernel) that will enable the Dom0 to see the DVD-ROM device?

[CentOS] Segafault Apache 2.0.59 Release 1.el4s1.10.el4.centos anyone?
Hi everyone, I have this package installed, and Apache has been sefaulting randomly on my server. I have tried to locate the fault and believe the problem may be in mod_php. However there are various posts that say that HTTPD could have an issues as well. Is anyone else having similar issues? Any feedback is welcome thanks. If httpd crashes again I should have a segfault dump and I will make that available.

[CentOS] Apache2 crashes, MySQL uses upto 90% CPU
Hi everyone, I am running CentOS 4.6 and use the centosplus repo. Apache version 2.0.59 and MySQL 5.0.54 and for the past few days Apache 2 has been crashing randomly. The CPU usage has been maxing out (The machine has 2 x Xeon processors, with 4Gb RAM) and there are many httpd processes that appear to be defunct. I read around and found that logrotate may be crashing Apache if it doesn't quit in time. I have performance tuned MySQL to cache queries, modified php.ini not to use too many persistent connections, restricted the number of connections that Apache will answer to. Top says: 8136 mysql 16 0 202 51:55.73 5.7 680m 225m 5352 S mysqld Is there anyone else experiencing similar things? Any suggestions?
