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: http://compnetworking.about.com/cs/novellgroupwise/ht/setpassiveftpie.htm
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
