similar to: Disabling IPv6 in CentOS 4.7

Hello, I'm running a CentOS 5.6 server through linode. I am atempting to configure it for ipv6, previously this had been done though not by me on a ubuntu box so the hardware can take it. I've got an ipv6 tunnel through Hurricane Electric and at a shell prompt have done the following: ifconfig sit0 up ifconfig sit0 inet6 tunnel ::IPV4 Address ifconfig sit1 up ifconfig sit1 inet6 add IPV6

It seems that lustre puts its modules in /lib/modules/2.6.16.21-0.8-default despite the fact that my kernel is 2.6.16.21-0.8-smp ! uname -a Linux n32 2.6.16.21-0.8-smp #4 SMP Sun Sep 24 08:47:30 BST 2006 i686 i686 i386 GNU/Linux make[3]: Nothing to be done for `install-exec-am''. /bin/sh ../../mkinstalldirs /lib/modules/2.6.16.21-0.8-default/kernel/fs/lustre /usr/bin/install -c -m 644

Hello folks, I am running Xen 2.6 under Centos 5.2 installation, and am trying to port Xen migration abilities to Infiniband. But, the InfiniBand drivers do not work under Xen kernel, only under non-Xen kernels. It looks like I need to install some patches to rectify the situation. Has anyone ever worked with Infiniband and Xen and would be able to give me inputs about the same? I would really

Hi there, While I was looking "how to disable ipv6 under centos" I have found a gazzillion pages about how to do it and some of then even list things that i am not sure where they came from, so for the record I list most of them here in case someone else need them. Some of the methods involved the direct modification of system scripts, and I am against that so I wont list them here

How about, in your /etc/sysconfig/network file adding or editing the line for IPV6 to be: NETWORKING_IPV6=no and then try a 'service network restart' and see what you get.

Greetings. I see a warning message while compiling OpenMPI and would appreciate it if you tell me what it means. This warning happens with any OpenMPI > 1.6.5. Even before starting a cluster, just "sessionInfo" triggers this warning. I'm pasting in the message from R-3.3.2 (this is MRO). Do the R parallel package cluster functions violate the warnings described here? >

This issue was brought up about a year and a half ago. So I''ll bring it up again and see if anything happens. I''ve got an infiniband network and am attempting to pass the infiniband card through the host and give it to the guest. I''m working with standard CentOS 5.2 on both guest and host with their provided xen (3.0.3 ish). I''ve also attempted to install the

Hello! I am having a strange issue with CentOS 5.4 that I cannot seem to solve. Every DNS lookup results in AAAA records being requested first before A records. As a result, this causes a large amount of unnecessary DNS traffic on the network. IPv6 has been completely disabled on these servers: /etc/modprobe.conf, ipv6 off and net-pf-10 off /etc/sysconfig/network, NETWORKING_IPV6=no lsmod |

Sorry - that should be sysctl -w net.ipv6.conf.all.accept_ra=0 to disable that, not 1.

I got Rmpi to compile with little difficulty, but had a tricky time setting the LD_LIBRARY_PATH to use the OpenMPI libs. I now get a different error when I try to load Rmpi > require(Rmpi) Loading required package: Rmpi librdmacm: couldn't read ABI version. librdmacm: assuming: 4 libibverbs: Fatal: couldn't read uverbs ABI version. CMA: unable to open

I'm putting the finishing touches on a new server, which will be replacing an old one. It's got a non-rpm ruby package (I hear lots of not-nice things about the RH package). The new server had ruby installed, so I went to yum remove it. And it removed ibutils as a dependency of ruby or ruby-libs. rpm -qi of ibutils tells me Summary : OpenIB Mellanox InfiniBand Diagnostic Tools

I want to seriously work with IPv6 and not have stray IPv4 functions messing with me. So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have NETWORKING_IPV6=yes. In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on it (have IPV6INIT=yes and IPV6_AUTOCONF=yes). But lo had IPv4. So I commented

I can't get IPv6 routing to configure correctly despite everything I've read saying it should This is my network config on a fully-updated CentOS 5.8 system: # cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=my.hostname.com GATEWAY=aaa.bbb.ccc.ddd IPV6_DEFAULTGW=2a02:aaaa.bbbb::1 IPV6_DEFAULTDEV=eth0 # cat /etc/sysconfig/network-scripts/ifcfg-eth0

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A few months back, I tried to use the network scripts to provision an IPv6 range like can be done with IPv4. I was using CentOS 5.2 at the time and was informed that 5.2 was broken in this regard. I have upgraded to CentOS 5.3 now and I am trying to get IPv6 to provision an entire range of IPs, but I am still getting the old behavior and no IPs are

Hi, I'm currently reading chapter 13 of the RHEL Deployment Guide, and taking some notes. I have a few minor questions: /etc/sysconfig/network According to the doc: "This file specifies routing and host information for all network interfaces." Here's how mine looks like: --8<----------------- NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=fujitsu.zuhause
