    I currently have HTTP loadbalanced just fine with the LinuxDirector.
I've setup SMTP in the same fashion, and I don't have as much luck.

    For example. ... Let's say I have a virtual server called
When I telnet to its port 80, I connect and immediately can type "GET /" and
get a webpage and disconnect.

    However, when I telnet to port 25...

[tpavlic@ctraid tpavlic]$ telnet 25
Connected to
Escape character is '^]'.

    And it sits for about THIRTY seconds. Then, after thirty seconds...

220 ESMTP Sendmail 8.9.3/8.6.9 ready at Tue, 29 Jun 1999
17:29:54 -0400

    And everything is fine.

    Any idea about what is happening during those thirty seconds?

    I'm runing Linux 2.2.9 with LVS 0.5. I'm using the direct routing (-g)
method. My client servers have all been compiled with the arp.c from the
LinuxDirector. They are using the tunl0 (and its aliases) (with ARP turned
OFF (-arp) ) to accept packets directed to my virtual IPs...

    Any help would be greatly appreciated.

    All the best --
    Ted Pavlic
