Dale,
When I upgraded to Solaris 9, the wu-ftpd 2.6.2 server (that comes with Sol9)
required tighter adherence to the RFC-specified protocols. My mvme-177
vxWorks BSP's implementation of the ftp protocol does not strictly adhere to
the specifications.  In my case I had to wait almost 7 minutes to boot.  If
you want I can send you a document explaining how to patch the wu_ server to
support so-called 'broken-clients', which then boots the IOC in the normal
fashion.

Subject: vxWorks and ProFTPD

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
