Could also be the fact that the firewall, by default, expect an end of line response from the ftp server, when it doesn't get one then it just hangs for a very long time until the connection eventually times out. There is a modification to the base.def which is to comment out the line "ENFORCE_NEW_LINE" by adding a // to the front of it. This change is made on the management station and then push a policy down to the modules. I believe this should resolve your issue. -----Original Message----- From: "Scheidel, Greg (Contractor)" <[email protected]> Date: Wed, 2 Jan 2002 16:17:06 -0500 To: [email protected] Subject: Re: [FW-1] Connection reset after login to FTP server? > Kevin Martin: > > Some ftp servers want to know who you are coming > > in (name resolution).
