Hello, HP-UX fans!

The following is an excerpted note from one of my Big Blue Buddies with
all company proprietary info deleted  ;-)

I am not sure whether or not this is an HP or an IBM problem (although
my friend does not mention this sort of a failure on other vendor's
hardware/software).  

Maybe someone from within the HP labs can help here???

Subject: FTP PORT command failure from HP nodes

Steve, we have seen a problem for a long time where FTP sessions from IBM
TCPIP to an HP node would fail when the FTP application issued a PORT command.
By testing the PORT command manually, I find that HP nodes are not accepting
port arguments where the first decimal portion of the port address is 3 or
less (ie PORT 192,25,80,1,3,200). I found nothing in the RFC indicating a
limit or restriction.

Is there some HP documentation about FTP PORT command limits or someone we can
call to resolve this?  (A remote site) has this problem too.

History:

    FTWENG is an IBM 43xx machine at IP address 192.25.80.1 via an
    8232 Ethernet interface box

    CAMDEV is an HP370 at IP address 192.25.80.50 running HP-UX 7.0


To see the problem, FTP from FTWENG to an HP node (CAMDEV) and issue

  QUOTE PORT 192,25,80,1,3,200

(this will fail)

  QUOTE PORT 192,25,80,1,4,200

(this will work)

Any ideas out there?
