The option to force IGMP to version 2 was added in Update 4. You should be able to upgade to update 4 by doing an up2date and letting the system upgrade your packages. Once you are booted to the kernel that is installed as part of update 4, you can use the following command to force IGMPv2: /sbin/sysctl -w net.ipv4.conf.eth0.force_igmp_version=2 Note that the kernel is usually not installed with up2date, so you'll need to do up2date --force --update kernel or up2date --force --update kernel-smp Thanks, James Cooley > > Hi all, > > I am using Redhat Enterprise Linux update 3 on one of my server, > The server connected to a router.
