Hi,
Have a strange problem when trying to use FrontPage 2003 FTP for uploading
to a server. All the files is transferred but at the last one FrontPage FTP
hangs.
Looking at the transmission in Ethereal you se that for all files FrontPage
FTP
issues a PASV command and gets a response with the protnumber to use.
(Sitting behind a NAT so I have to use PASV and the server supprots it).
When the last file is transferred it issues yet another PASV command and
gets a response with a new portnumber. BUT, here comes the strange thing,
it tries to establish a tcp-connectionj using the previous PASV response
portnumber i.e. that used when transferring the last file.
The same happens if I only uploads one file. The file is correctly
transferred but
the FrontaPage tries to establish a new data connection.
I do not understand why this last PASV command is issued as all files have
been
transferred and, furthermore, I don't understand why an old port number is
used by frontpage to set up the TCP connection.
Maybe this have been discussed earlier on this list. If so please forgive me
for my ignorance. Please advise me if and how this problem could be solved.
Thanks!
For those interested in the details I have appended a condesed version of
the Ethereal logs:
TYPE A
200 TYPE is now ASCII
PASV
227 Entering Passive Mode (81,228,11,138,180,63)
Passive port = 46143
STOR aktuellt.htm
150 Accepted data connection
226-459772.9 Mbytes free disk space
226-800 Kbytes used (7%) - authorized: 10240 Kb
226-File successfully transferred
226 2.417 seconds (measured here), 4.20 Kbytes per second
Data thus transferred and the passive data connection is closed but now
FrontPage FTP tries to open a new data connection:
TYPE A
200 TYPE is now ASCII
PASV
227 Entering Passive Mode (81,228,11,138,180,63)
Passive port = 38936
TCP 1927 > 46143 [SYN] Seq=0 Win=65535 Len=0 MSS=1460
I.e. Frontpage FTP tries to use the previous port in a new data connection
without
having anything to send !!!???? And of course the server terminates the
session
and FrontPage tries to login in again and does the same misstake and this
scheme
continues ad nauseum. Aborting makes FrontPage crash!!!
