I have one load balancer pair and one web server pair. TIam using NAT to forward the requests with round robin. Web servers are running 2 web services. Each web service accepts connections strictly on IP of one of the two physically different interfaces i.e.one web service accepts connection only on ip address of eth0 and other web service accepts connection only on ip address of eth1 on web server. I am trying to configure 2 virtual ip addresses on load balancer. One virtual ip address will forward the request to one pair of web service i.e web service bound to eth0 of 2 web servers and other virtual ip address will forward the request to other pair of web service bound to eth1 of 2 web servers. After doing the configuration above one of the virual web service on load balancer does not detect the real web service. But I am able to access that service using telnet or web browser from the load balancer. Can someone help me resolving the issue ?? regards, raj __________________________________ Do you Yahoo!?

If you're trying to avoid having any costly shared disks attached, one option would be to use NBDs (Network Block Devices) which can be used as raw devices by multiple nodes - this may work. Hopefully this is of some use.

If you do not solve problem using Piranha, for IP failover you can always try heartbeat (http://www.linux-ha.org). -- Eng.

Generally, that's the case. You need shared storage to do it. I've heard of people using firewire for testing, but haven't done it myself. -- Lon From Martin.Zehetmayer at HVBInfo.com Wed Sep 8 17:29:30 2004 From: Martin.Zehetmayer at HVBInfo.com (Martin.Zehetmayer at HVBInfo.com) Date: Wed, 8 Sep 2004 19:29:30 +0200 Subject: routing problem with lvs?

E.g. links -source https://www.host.com You might be able to use stunnel as well, but it's probably easier to use something that's already got SSL built in rather than multiple utilities... -- Lon
