While trying to figure out why things aren't working for me, I came
across this:

# ipvsadm -C
# ipvsadm -A -t xx.yy.178.1:80 -s rr
# ipvsadm -a -t xx.yy.178.1:80 -r 192.168.0.195 -g         
# ipvsadm -A -t xx.yy.178.1:23 -s rr -p                  
# ipvsadm -a -t xx.yy.178.1:23 -r 192.168.0.195 -g 
# ipvsadm
IP Virtual Server version 0.9.7 (size=131072)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port          Forward Weight ActiveConn InActConn
TCP  xx.yy.179.1:telnet rr persistent 360
  -> 192.168.0.195:telnet        Route   1      0          0         
TCP  xx.yy.179.1:www rr
  -> 192.168.0.195:www           Route   1      0          0         
# ipvsadm -L -n
IP Virtual Server version 0.9.7 (size=131072)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port          Forward Weight ActiveConn InActConn
TCP  xx.yy.178.1:23 rr persistent 360
  -> 192.168.0.195:23            Route   1      0          0         
TCP  xx.yy.178.1:80 rr
  -> 192.168.0.195:80            Route   1      0          0         

...which I found to be a little confusing, as 'xx.yy.179.1' isn't the
same as 'xx.yy.178.1'

Now, once upon a time, xx.yy.179.1 and xx.yy.178.1 were IN PTR'd
to the same hostname.  I've since changed that (and maybe it's not
fully taken hold yet), but it's resolving xx.yy.178.1 to the old
hostname, and then resolving the old hostname back to xx.yy.179.1.

Regardless of the state of my DNS cache, should this be happening?
