Hi list, I am seeing some odd connection behaviour between LVS and clients. I regulary see that the client->LVS connection count is higher from the client side than when I look at it on the LVS.
For example, on the client side here's what I see: client:~# netstat -antp | grep 389 tcp 197 0 10.10.5.247:32986 10.10.3.169:389 ESTABLISHED 1567/nslcd tcp 0 0 10.10.5.247:33343 10.10.3.169:389 ESTABLISHED 1567/nslcd tcp 0 0 10.10.5.247:33250 10.10.3.169:389 ESTABLISHED 1567/nslcd tcp 0 0 10.10.5.247:32993 10.10.3.169:389 ESTABLISHED 1567/nslcd tcp 0 0 10.10.5.247:60957 10.10.3.169:389 ESTABLISHED 1567/nslcd And at the same time on the lvs I see: lb1:~# ipvsadm -Lnc | grep 10.10.5.247 TCP 08:35 ESTABLISHED 10.10.5.247:33250 10.10.3.169:389 10.10.5.34:389 TCP 08:35 ESTABLISHED 10.10.5.247:33343 10.10.3.169:389 10.10.5.34:389 TCP 06:16 ESTABLISHED 10.10.5.247:32993 10.10.3.169:389 10.10.5.38:389 I am trying to understand why the client has 5 established connections to LVS, while the LVS only has 3 open to the client. Is this normal behaviour? I should add that I see this regularly on many systems. * The clients are all running Ubuntu (10.04 or 12.04) with nslcd 0.7.2 * The LVS is running Ubuntu 12.04, Kernel 3.2.0-24-virtual, ipvsadm 1:1.25.clean-1ubuntu5 Thanks in advance, -- Khosrow _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-requ...@linuxvirtualserver.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users
