Joe,
The output from the arp -a command is as follows:
? (192.168.1.254 at 00:08:C7:50:96:19 [ether] on eth0
? (10.0.0.1) at 00:60:97:1D:03:12 [ether] on eth0
real2.server.net (10.1.1.3) at 00:08:C7:50:96:19 [ether] on eth0
real1.server.net (10.1.1.2) at 00:08:C7:A8:E0:69 [ether] on eth0
I have changed the default gateway for the director to be the client (I had
already tried this, but was unsure if it was right) and run the following two
commands also, as suggested by someone else:
echo 0 > /proc/sys/net/ipv4/conf/all/send_redirects
echo 0 > /proc/sys/net/ipv4/conf/eth0/send_redirects
Now I can get multiple reloads for one server but the other one does not seem
to want to reply!
I dunno!
