Mailing List Archive: LVS/NAT config

I have a couple of questions that I can't seem to find the answer to. Any
help would be
appreciated. I have 3 boxes in my cluster, one server and two real nodes.
There are two problems that I am running into: 1. I get a connection
refused message whenever I try to access the cluster on port 80 with telnet
via the
floating IP address. 2. After nanny runs for both real
nodes, I see two ssh commands looking for the real node uptime. These
processes never complete. It's almost like they are blocked. The
interesting thing is that I can run the same command from the command line
and it returns immediately with the results. SSH is set up correctly with
the authorized_keys file on both real nodes. ipchaining is set up
correctly, because I can ping out to the global network from within my
private network were the real node are. I also ran netstat on the virtual
server, and port 80 is NOT open. Has anyone seen this before?

I'm using RedHat 6.2 kenel version 2.2.14-5.0.

Thanks,

David Morley

Connection refused means that there is nothing listening on port 80.
If your LVS is working correctly then the service isn't running on the VIP
on the real-server.

2. After nanny runs for both real

don't know anything about nanny. Try the piranha mailing list.
