Re: [Users] Re: 2.6.18-ovz028test015 and 2.6.18-ovz028test018 break IPv6

Some time in the very later part of the 2.6.18 kernel.org release updates, a problem was introduced that broke IPv6. Some patch or another caused nodes to fail to join the all nodes multicast (ff02::1) address. This is critical to IPv6 router discovery and advertisement, neighbor discovery, and autoconfiguration. All fall down go boom. I've raised that same issue here: http://bugzilla.openvz.org/show_bug.cgi?id=476 But even though Den Lunev found and backported the upstream patch (I think from 2.6.20) that fixes the problem, I don't think this ever got into the OpenVZ repository... any update on this? As Kirill said in comment #4 to the bug, this patch goes to 028test019 -- which is not yet released. So you either have to wait till we release 019 (or later) kernel, or use the patch from the bugreport. ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
[Users] Using veth on debian
Hi all, today i need setup a Virtual Server with a veth device since a commercial Software required a Mac Address for the license. I think that it won't be the lasttime that we require such a setup (unfortunately), therfore I put some more effort into the scripts and added information to the wiki. http://wiki.openvz.org/Virtual_Ethernet_device I basicaly change the vznetaddroute script mentioned in the wiki: #!/bin/bash VZCONFDIR=/etc/vz VZHOSTIF=$BASH_ARGV . $VZCONFDIR/conf/$VEID.conf if [ -n $VETH_IP_ADDRESS ]; then echo Adding interface $VZHOSTIF and route $VETH_IP_ADDRESS for VE$VEID to VE0 /sbin/ifconfig $VZHOSTIF 0 echo 1 /proc/sys/net/ipv4/conf/$VZHOSTIF/proxy_arp echo 1 /proc/sys/net/ipv4/conf/$VZHOSTIF/forwarding /sbin/ip route add $VETH_IP_ADDRESS dev $VZHOSTIF else echo found no VETH_IP_ADDRESS in $VZCONFDIR/conf/$VEID.conf! exit 1; fi exit with this little script one is finaly able to just apply changes to the VE's config file by adding a VETH_IP_ADDRESS variable including the desired IP Address, the rest is done by the script. I decided to not include the sysctl / proc settings for forwarding and proxy arp into this script since I prefere the /etc/networks/ interfaces way. e.g. auto eth0 iface eth0 inet static address 10.1.1.1 netmask 255.255.255.0 network 10.1.1.0 broadcast 10.1.1.255 gateway 10.215.1.254 dns-nameservers 10.215.1.20 dns-search prod.your.domain up sysctl -w net.ipv4.conf.eth0.proxy_arp=1 up sysctl -w net.ipv4.conf.eth0.forwarding=1 Hope this helps someone ;-) Nils Domrose ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
