Hello, I'm trying to do load balancing of incoming traffic to my applications. This applications are not very smp friendly, and I want try to run some instances according to number of cpus on single machine. And balance load of incoming traffic/connections to this applications. Looks like is should be similar to http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.localnode.html linux kernel 2.6.32 with or without hide interface patches. Tried different configurations but could not see packets on application layer. 192.168.1.165 - eth0 - interface for external connections 195.0.0.1 - dummy0 - virtual interface, real application is binded to that address. Configuration is: -A -t 192.168.1.165:1234 -s wlc -a -t 192.168.1.165:1234 -r 195.0.0.1:1234 -g -w #ipvsadm -L -n IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 192.168.1.165:1234 wlc -> 195.0.0.1:1234 Local 1 0 0 # Log: [ 2106.897409] IPVS: lookup/out TCP 192.168.1.165:44847->192.168.1.165:1234 not hit [ 2106.897412] IPVS: lookup service: fwm 0 TCP 192.168.1.165:1234 hit [ 2106.897414] IPVS: ip_vs_wlc_schedule(): Scheduling...

I tried to make dummy0 a hidden device and play with arp settings. But without result. I will be happy to hear any idea how to do connection in this environment. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
