I'm having a bit of an issue trying to get tornado 2.02 to boot from
a RAID network storage appliance (ReadyNAS from Infrant) running
ProFTPD v.1.2.9 under a version of Linux. The problem is that
downloading the boot image takes around 6-7 minutes. Downloading the
script file happens normally, in a couple of seconds. I've found no
diagnostics in the server log other than statements showing that the
first session opens and closes ~7 minutes later, and the second
session opens and closes in a few seconds. This appears to be
different than the situation in which the second file or a second
reboot takes a long time because of inability to reuse the port. My
problem happens first time, every time. I've connected to the server
with various mac, windows and solaris clients w/ no problems. I have
however seen a problem w/ WS_FTP v4.50 that could be similar. I found
some info mentioning slow connections due to a reverse DNS lookup by
ProFTPD, but the vendor sent a config file patch that supposedly
prevents this reverse lookup, with no effect. I would appreciate any
suggestions or info as to whether anyone has successfully used either
this particular NAS or ProFTPD in other environments.

thanks
