Hi,

I've setup LVS-DR because i can't get NAT to work, and i think i will need
it anyway. I posted a mail a couple of days ago, about a connection that
can't be made:

[client] --> [LVS] --> [Terminal Server] --> [telnet host]

Sometimes i can't make the last (telnet) connection. The connection simply
times out. When i try it a couple of times though, it suddenly works. First
i thought it was an incorrect configuration of the loopback adapter on the
TS, but that doesn't seem to be the solution anymore though.

Tcpdump doesn't show anything amiss (i don't see the shower of packets Horms
hinted at - everything seems pretty normal). Also, i think i've configured
the loopback adapter correctly as well:

IP: same IP as LVS virtual IP
Mask: same netmask as LVS
GW: same GW as the rest of the network
DNS1/2: same as rest

Also, is it necessary to run a time sync between the two LVS's? 

Thanks,


Léon
