Hello All Currently on a CentOS 4.3 system with the 2.6.14.3 kernel. Is there a recommend way to properly recompile the kernel? I was thinking of dling the source from kernel.org, but I was told that using SRPMs would be better? Any suggestions ?

...ding, using a ultra-classic PREROUTING / FORWARD rule, was given a TCP RST in the best scenario. We read here stories about activating NAT / masquerading on the domU to fix (???) this issue, but as the machine is meant to be hosted, that was not the cleanest approach. And then we took a look at IPVS (http://www.linuxvirtualserver.org/software/ipvs.html), an opensource Linux kernel module initially meant to act as a loadbalancer. We thought that providing a unique real server (the domU) to the VIP would do the trick... and it did ! Here''s a quick example of a working configuration...

Hi, just in case some ipvs knowledgable people read this... I tried to find some info on ipvs destination hashing on the net but did not find anything... Right now we have a basic direct routing round-robin keepalived configuration: abc.example.com (a.b.c.d) => LVS ( round-robin ) => server_[1..n] with IP[1..n]. I...

Hi Rich I'm able to solve the problem regarding PAPR in libguestfs on my powerpc ubuntu.By default the libguestfs was configuring pseries machine and afterwards I changed it to my original machine i.e ppce500 .The changes are performed in ./src/guestfs-internal.h file.

We have found a critical problem with the XEN 3.1 release (for those who are running 15-20 VMs on a single server). We are using the official XEN 3.1 release on a rackable server (Dual-Core AMD Opteron, 8GB RAM). The problem we are seeing is that intermittently vifs fail to work properly in VMs after we create around 15-17 VMs on our server (all running at the same time, created one by

I need some help understanding SIP dialog. Some actor is trying to access my server, but I can't figure out what he's trying to do ,or how. I'm getting a lot of these warnings.

Is the IP Virtual Server available by default in the stock 2.6.18-128.1.14.el5? Or shall I compile my own kernel? I did check "config-2.6.18-128.1.14.el5" yet I am not that sure! :) Usually how long does it take to compile the kernel on a modern machine?

Hello, I'm beginning to give up on making Linux-HA's heartbeat work for my environment (CentOS x86_64) and am wondering what other option have I got to help me: 1. Use IPVS to maintain a cluster of virtual servers, either master/slave or load-balanced. 2. Use DRBD in master/slave fashion to keep a home-grown application highly-available. The first thing I stumbled upon is RedHat Cluster Suite ( http://www.linuxtopia.org/online_books/centos_linux_guides/centos_cluste...

Does anyone know what this means and how to fix it? I know it looks like a file named lockhelp.h is missing. What can I do to fix it?

We are looking to set up a cluster of machines using LVS and running EXT3 on each machine. Does anyone have any feedback on doing this? Any known gotchas? The stable version of IPVS kernel module is for 2.4.12. The latest stable kernel in 2.4.16 The latest patch for ext3 is for 2.4.14 or 2.4.17pre2. Any suggestions on what combo to try? Thanks, Charlie

Been running this for quite a while and noticed that have intermittent problems getting out. Find that if I ping the same site from 2 computers it may work on one and fail on the other. Also was surprised that some time they are going out different interfaces at the same time. Seems to work all the time from the firewall.
