Hello I have a change of behavior with ipvsamd from centos 5 to centos 6. I use ipvsadm to dispatch http. In this case, Ipvasadm and http run on the same server. With centos 5, connect to one server when I do a TELNET VIP 80 on the server , the telnet doesn't care of ipvsadm and I think the VIP monted in loopback directly respond. This is the behavior I want But now with centos6 when I do a TELNET VIP 80 on the server, the telnet enter in the ipvsadm virtual table. Why the VIP mounted in loopback doesn't respond directly. ?
Here is the configuration to reproduce the case : The VIP is 10.30.145.179 mounted in loopback and in eth0 : [root@lsn21510<mailto:root@lsn21510> ~]# ip addr sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet 10.30.145.179/32 brd 10.30.145.179 scope global lo:10 inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:9e:51:87 brd ff:ff:ff:ff:ff:ff inet 10.30.145.178/22 brd 10.30.147.255 scope global eth0 inet 10.30.145.179/32 scope global eth0 inet6 fe80::20c:29ff:fe9e:5187/64 scope link valid_lft forever preferred_lft forever I just add a add a virtual service without real server : ipvsadm -A -t 10.30.145.179:80 -s rr [root@lsn21510<mailto:root@lsn21510> ~]# ipvsadm -ln IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 10.30.145.179:80 rr The server web is working : [root@lsn21510<mailto:root@lsn21510> ~]# netstat -ltunp | grep 80 tcp 0 0 10.30.145.179:80 0.0.0.0:* LISTEN 1437/httpd Now if I do a telnet 10.30.145.179 80 on centos5 it works because it bypass the ipvsadm and the loopback respond. On centos 6 the telnet doesn't work because the request follow the virtual table define by ipvsadm. Do you how I can have the same behavior in centos6 that I have in centos5 ?
