I've experienced similar problems (specific to Windows console FTP piped
through multiple shells).  

I wish I could say I tracked down the cause of the problem, but alas I did
no such thing.

Using TFTP cleared the problem right up, and I've not experienced it since.
Using ncftp in place of the native windows version was another option, but I
though tftp a nicer solution for my purposes.

hi. We are doing some stepping stone detection. During the experiment, we
ran into a problem. Starting from machine A(fedora), we connect to machine
B(rd8) by using smb exploit code. Then, we connect to machine C(windows
2000) by using RPC exploid code from machine B. Now, the connection path
is A-B-C. Next, we tried to ftp some files to machine C by using the
windows shell we got. Once it entered ftp mode (I mean after input the
password). It just hung there. We can not exit ftp. The whole connection
just froze.
Is it possible related to different shells or something else? Thanks very
much for your suggestion.

wishes,

xin
