I have to apologize for all the traffic I've recently caused here. I don't
mean to whine about my own problems so much. :(
Anyway -- I'm runing the LinuxDirector on a machine and using direct routing
to load balance between the servers behind it. (well.. really along side of
it)
I allowed ports 20 and 21 and normal FTP works great. However, whenever I
try passive FTP (I'm using the ncftpd server, by the way) -- this happens:
[tpavlic@ctraid tpavlic]$ ftp 10.200.0.15
Connected to 10.200.0.15.
220 www.netwalk.com NcFTPd Server (licensed copy) ready.

(I tried to show an example of port working and passive not)
In ncftpd, there is a configuration option that allows you to set the
passive-ip for this certain situation. I've done that. (Notice that the
connection is originally made to 10.200.0.15, however the passive tries to
connect to 216.69.192.197) Still, I get a connection refused as if an
attempt was being made to access the ftp server through the LinuxDirector.
And passive mode works fine when I go directly to the server. It's only when
I go through the LVS that I have trouble.
Thanks for any help you can give.
All the best --
Ted
