(Migrating to libnl3 would be better anyway as > distributions try to get rid of supporting libnl.) Nope, I'm using the default libnl coming with RHEL6.4. Its not really an option to import/change to libnl3 for RHEL6. But you could try poking Thomas Graf ;-) > I think sometime in libnl*, nl_handle_{alloc,free} was changed to > nl_socket_{alloc,free}. Yes, I can see that your libnl3 commit f48e93c1 (libipvs: libnl3: fix compilation error) caused this issue. > Maybe try changing include locations and libs that are linked against > to libnl3. We officially support ipvsadm for RHEL6, so its not an option to link against libnl3, as we need to supply an official package... else we/I would need to have an adaption patch in the RPM (I were looking to rebase RHEL6 to use the upcoming ipvsadm release). -- Best regards, Jesper Dangaard Brouer MSc.CS, Sr. Network Kernel Developer at Red Hat Author of http://www.iptv-analyzer.org LinkedIn: http://www.linkedin.com/in/brouer
