RE: Mysterious FTP failure - more info


I did a further test to verify the existence of the problem. I did the
following from a
locally invoked bash shell   [ for security - I "starred" out the hostname
]. I transferred
the file via ftp from the local box TO the local box into a sub-directory.
The same
behavior exists if the file is transferred to another box :

Subject:    RE: Mysterious FTP failure


After a bit of investigation - I've narrowed down some of the parameters of
the problem.
First of all the problem appears to exist only on NT4.0 - not W2K. Second,
it only exists if one first
telnets to the NT4.0 box and THEN invokes ftp and sends a file. If I use
ftp from a LOCAL
bash shell, the file transfers just fine. (The problem also exists it one
telnets to the box FROM
the box - i.e. - a remote connection is NOT necessary).

Furthermore, my memory indeed failed me. I did upgrade to the latest
version of cygwin,
cygwin dll's, and inetutils since the time I last had this working - about
a month or so ago.
Prior to that I had not upgraded for about four or five months (or more).
SO THERE WAS A
CHANGE ON MY NT BOX - AND THE CHANGE WAS A NEW VERSION OF CYGWIN AND
INETUTILS. What threw me off, was the fact that I had not attempted to ftp
FROM A REMOTE
CONNECTION since the upgrade. All the ftp's I did, I did from a local bash
shell - which works
just fine.

Of course none of this "proves" that the problem lies with new cygwin code.
If anyone running
NT 4.0 SP 6 could try to recreate the problem as described above - that
would be a big help.
