[CentOS-announce] MirrorList.centos.org is now available on ipv6
Hi Everyone, It gives me great pleasure to announce that mirrorlist.centos.org is now available on ipv6; in addition to the existing ipv4 functionality. This is a full featured service, using geoip on the server end to hand out local-to-user IPv6 mirrors. Every url handed out is verified at regular intervals and only the freshest ones used. Our IPv6 mirror network is presently just under 150 hosts spread over 32 different countries - with a large bias towards the USA and Western Europe. We would love to bring on more machines to get better coverage around the world. In the 30 minutes since we turned it on, we are serving just over 8 requests per second over ipv6. So while its not huge, its a significant number and one that we imagine will only grow. I would like to thank Anssi Johansson ( http://twitter.com/avij ), member of the CentOS QA team and resident IPv6 champion, for his efforts in pushing for this service. Then helping build it and test it. Note that we do not have DNS on ipv6, so we still rely on the user end hosts having an upstream dual stacke dns resolver enroute to ns*.centos.org - we will try and fix this in the near future. If you have any feedback, or run into issues, please come find us on irc at #centos-de...@irc.freenode.net or open an issue report at http://bugs.centos.org/ Enjoy the v6 goodness, -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc ___ CentOS-announce mailing list CentOS-announce@centos.org http://lists.centos.org/mailman/listinfo/centos-announce
[CentOS-virt] 100% load on core after physically removing USB storage from host
I encountered a problem after removing a USB flash drive using virtual machine manager, I notice that the core assigned to the VM guest goes up to 100% load. Within the guest itself, there is no significant activity. This also prompted me to look at the other physical machine from which I used the USB flash drive to transfer files. And it was also exhibiting the same problem. Installed versions are qemu-kvm-0.12.1.2-2.209.el6_2.5.x86_64 on CentOS 6.2, 2.6.32-220.17.1.el6.x86_64 (Intel C204 PCH) There are no error messages in the log files and things seem to be working except for the fully loaded core. After some testing, the only steps needed are 1. VMM add physical host usb device - select storage to guest 2. VMM remove hardware 3. Physically remove the USB storage from the host, thread/core assigned to guest goes 100% Repeating the same steps without restarting the guest causes cpu utilization to drop back to normal for about a second or so before going back up again. Problem goes away if I restart the guest. There don't seem to be anything related on RHEL bugtrack except one related to hotplug/unplugging a USB controller more than 1000 times. Is this is a bug or there is actually something else I am supposed to do before removing a physical device from a guest? Also is there anyway I get the core/thread back to normal without restarting the guest? ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

[CentOS] iptables: hitcount
Hello, up to CentOS 5.3 it was possible, to control new ip connections by recent, seconds and hitcount -A INPUT -m state --state NEW -m recent --set -p tcp --dport 80 -A INPUT -m state --state NEW -m recent --update --seconds 60 --hitcount 1000 -p tcp --dport 80 -j LOG --log-prefix FW DROP IP Flood: -A INPUT -p tcp -m tcp --dport 80 -m state --state NEW -m recent --update --seconds 60 --hitcount 1000 -j DROP -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT so that - short time high new connections rate for the web server where accepted, but not over a longer time. E.g. CentOS 5.8 or CentOS 6.2 accept only -A INPUT -m state --state NEW -m recent --set -p tcp --dport 80 -A INPUT -m state --state NEW -m recent --update --seconds 1 --hitcount 15 -p tcp --dport 80 -j LOG --log-prefix FW DROP IP Flood: -A INPUT -p tcp -m tcp --dport 80 -m state --state NEW -m recent --update --seconds 1 --hitcount 15 -j DROP -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT So a complex web page with many small icons e.g. webmail pages initiate the log in line 2 and drop in line 3 . hitcount does not accept values of 25 or above: [root@server ~]# iptables -A INPUT -m state --state NEW -m recent --set -p tcp --dport 80 [root@server~]# iptables -A INPUT -m state --state NEW -m recent --update --seconds 1 --hitcount 25 -p tcp --dport 80 -j LOG --log-prefix FW DROP IP Flood: iptables: Unknown error 4294967295 what can i do to protect the web server?

You may be confusing two different things: static IP addresses for
individual hosts and static routes to route IP traffic to certain subnets.

Simply put in a multi-port NIC card, Another questions...I put in another network port I end up with 3 NICs 3 bridges...One providing Internet access, One providing routing to virtual hosts and one providing route to ltsp network. Now, traffic among these three networks will be routed automatically No. Multi-homing in this fashion is complex. You will require advanced routing on all of the guests to accomplish it. Shorewall makes this easier, but you'll need to create multiple routing tables using 'ip route', mark packets based on their destination, and then select the appropriate routing table based on firewall marks.
