We are the client.

 

Client IP:3039                     Server IP:21

Server IP:20                        Client IP:5001

 

I see the above in Ethernet Peek. The data is received when I check the packets in the sniffer but the Windows FTP client hangs. It does not complete the save.

 

I am using the Windows FTP client because my Visa EA server does not allow any normal commands to be executed. Does FileZilla have a command-line client ?

 

 

Thanks,

Mohan

Sounds like active/passive FTP problem.

Windows FTP uses active mode by default.

 

Active mode can often have trouble working through firewalls/routers.

 

When you have connected to the ftp site type the command ‘literal pasv’ which should switch the client into passive mode.

To make permanent default see here:

Better still use a decent ftp client like filezilla

http://filezilla-project.org/download.php

 

Also remember if your not using sftp or scp the traffic or the password to the ftp site is not encrypted……

Hi,

          I have a ftp connection to a server and I am trying to analyze why even though wireshark shows that the files are transferrred successfully Windows ftp does not complete the transfer. How do I go about analyzing the problem ?

 

Wireshark shows

 

226 Transfer complete successfully.

 

but the windows ftp client does not save the file. It hangs. So what was working a few days back is now hanging. What type of analysis should I run ?

 

 

Thanks,

Mohan
