I have a server that many customers connect into via FTP to upload/download information to mobile units in the field. One customer, and only one, seems to have an issue where an active FTP connection is staying open for days at a time, though I know that the mobile unit has disconnected and rebooted. Inactive sessions timeout properly, but somehow active sessions are kept open.
First question is does anyone know of any network hardware such as a firewall/packet shaper or router which would hold open an active FTP connection which was initiated from behind it?
If that doesn’t do it, my next question would be about forcing a disconnect of any active session over 10 minutes in IIS. There is nothing in the GUI but maybe there is a metabase option or a scripted option.
Any other thoughts? Thanks.
