I have tried /32 but the script doesn't add the gateway
for the director(gw = clientIP), and I couldn't do it
manually ( # route add default gw 192.168.81.20 netmask
0.0.0.0 metric 1 eth1:10 SIOCADDRT: Network is
unreachable), so there could not be communication between
the director and the client. But from what I have read in
the mini-HOW TO NAT works with a /24 mask for the VIP, so
I tried that way.
yes there's a bug in the script which I documented
somewhere, and I haven't fixed because few people are using
it.
did you get any errors from the scripts as they were
setting up? I've always got a working LVS when the scripts
exit without errors.
In the case of a /24 mask for the VIP I can ping real
server - client, in the case of /32 I cannot,becouse of
the routing table, as I have said before. Indeed I got
errors from the script , but that was because of my 2.6.15
kernel (the script was tested only for 2.2.x and 2.4.x).
you're keeping the errors secret? What they are it the
central part of the problem here.
Do you think that is the real problem? It's said that the
script is expected to work on 2.6.x kernels.
I expect nothing is going to work with ethernet aliases in
2.6.x kernels. There are scripts to run by hand to setup the
director for LVS-NAT in the mini-HOWTO. You'll have to
change the lines that set up the VIP to use 'ip addr add dev
eth0 VIP brd+ ...' (or something like that) instead of using
ifconfig to set up an ethernet alias. Read the section on
iproute2 in the HOWTO (you can't use ifconfig anymore to see
the VIP)
SYN+ACK,tcpdump used), the packet arrives on eth0 (I use
two NICs) on the director but it doesn't get to eth1:10,
eth1:10 doesn't exist anymore and tcpdump doesn't know about
it either.
