How I recompile the kernel is select the module that I need IP virtual server support >> -> [*] TCP load balancing >> -> [*] UDP load balancing >> > then do a make followed by a make modules_install. ip_vs is in my list of modules (the only ip_vs*) and does not return an error when I modprobe it but these are not there: #lvs ip_vs ip_vs_rr ip_vs_wrr ip_vs_lc ip_vs_wlc ip_vs_lblc ip_vs_lblcr ip_vs_dh ip_vs_sh ip_vs_sed ip_vs_nq ip_vs_ftp I am using kernel 2.6.30r5 Thanks for you Help, Ninus.
