Hi All, I have some load balancing troubles using lvs/piranha, here is the description : when i use the ipvsadm command to view the statistics here what i get : IP Virtual Server version 1.0.8 (size=65536) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn UDP 10.11.11.230:radius wrr -> 10.11.11.20:radius Masq 1 0 0 -> 10.11.11.19:radius Masq 1 0 1 the load balancer keeps forwarding the request to only one server. in addition of that the counter of the connection established is always equal to 1. i've checked also in /var/log/messages, both servers are seen as available. here is my config file : backup_active = 1 backup = <a href="http://10.11.11.229">10.11.11.229</a> backup_private = <a href="http://10.11.11.121">10.11.11.121</a> heartbeat = 1 heartbeat_port = 539 keepalive = 6 deadtime = 18 network = nat nat_router = <a href="http://10.11.11.122">10.11.11.122</a> bond0.499:1 debug_level = NONE virtual gw_radius { active = 1 address = <a href="http://10.11.11.230"> 10.11.11.230</a> bond0.498:1 port = 1812 send_program = "radpwtst -s %h -noacct -noauth -auth_port 1812 -secret mysecret -status" expect = "OK" use_regex = "0" #load_monitor = uptime scheduler = wrr protocol = udp timeout = 6 reentry = 15 quiesce_server = 0 server GW_1 { address = <a href="http://10.11.11.19"> 10.11.11.19</a> active = 1 weight = 1 } server GW_2 { address = <a href="http://10.11.11.20">10.11.11.20</a> active = 1 weight = 1 } server GW_3 { address = <a href="http://10.11.11.21">10.11.11.21</a> active = 0 weight = 1 } } Thank you for your help Regards
