Hi,
I'm trying to make ldirectord work for smtp and having some issues.
Basically I have 2 servers which themselves run virtualization (via
virtualbox).
Server1 has a virtualized server running smtp (lets call it smtp1 ->
192.168.1.204)
Server2 also has a virtualized server running smtp (lets call it
smtp2 -> 192.168.1.102)
ldirectord is running on Server1, ip 192.168.1.200
So I have in my config:
virtual=192.168.1.200:25
real=192.168.1.102:25 masq
real=192.168.1.204:25 masq
service=smtp
scheduler=wlc
protocol=tcp
#persistent=600
# #netmask=255.255.255.255
checktype=connect
I have no problems getting to smtp1 and smtp2 from the ldirectord
server:
$ telnet 192.168.1.204 25
Trying 192.168.1.204...
Connected to 192.168.1.204.
Escape character is '^]'.
220 email1 ESMTP
$ telnet 192.168.1.102 25
Trying 192.168.1.102...
Connected to 192.168.1.102.
Escape character is '^]'.
220 maillgw2 ESMTP MailCleaner (Community Edition 2010 beta 3) Sat,

However, ldirectord only flows connections to the virtual server that
is local to itself (smtp1). No matter what I do, it will never use the
other smtp server (smtp2).
ldirectord considers both as valid and adds weight to them
sysadmin@vbox:/etc/bind/master$ sudo ipvsadm -L
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight
ActiveConn InActConn
TCP vbox:smtp wlc
-> email1:smtp Masq
1 1 1
-> mailgw2:smtp Masq
1 0 1
But again, never routes to the other smtp.
So I tried removing the smtp1 from the equation, and then even though
ipvsadm reports it is available for forwarding, that never works. I
never get the connection. If smtp1 is in the forwarding list, then it
works.
Any idea what could be wrong?
Thanks
Ricardo
