Re: Load Balancing Issue - can someone help?

I checked my config, and I'm not sure why it was reporting zero the first
time around.  I now have a weight of 1 for both entries, shown below:

IP Virtual Server version 1.0.8 (size=65536)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  172.20.12.231:22 rr
  -> 192.168.0.3:22               Masq    1      0          0
  -> 192.168.0.2:22               Masq    1      0          0

however, I still get the same end result of no connection.  I'm new to this,
but I based my config on the sample ldirectord.cf file to get as far as I
have now.

Ian
