The list benefits from the full discussion, (hence this is CC'd to the list), it's better to keep the full thread together for everyone to benefit and contribute.
cc'd back onto the list. (We like to see things as they develop rather than as a fait accompli)
For the benifit of the list:- My server sees the incomming ftp request and logs a "FTP session opened", Tony sees a login and/or welcome message and when he types in a username all goes dead the tcpdump -vv of the transaction from the server end is as follows :- Not being a ftp expert I decode as follows I see the three packet TCP handshake in the first 3 packets (2 from client 1 from server) (client port 32822) (server port ftp) I see a UDP handshake with my name server as i look up the client I probe the auth port twice but see no response I then try to send data back to the client port 32822 for which i never see a reply. My transmissions are repeated quite a few times then it stops/timesout etc If anybody really wants they can have the entire tcpdump but i feel it is unnecessary.
Yes so we have a basic handshake, if you do it again i have full protocol decoding on tcpdump ready to see what is sent where, may be you can do the same add the -vv option and we can compare notes afterwardsThis time I got the 220 welcome message followed by Name (cornelius ... ): so I typed 'anonymous' and it all went quiet and I killed it.
weird, ok i am going to post the tcpdump results back to the list as neil W suggests, to keep everone informed Robin Cornelius --------------------------------------------------- robin@xxxxxxxxxxxxxxxxxxxxx GPG Key ID: 0x729A79A23B7EE764 http://www.biglumber.com/x/web?qs=0x729A79A23B7EE764
