Hi Monah, Try turning on "Passive mode" in the settings of your browser. That should solve the problem. There are two ways in which an FTP connection can be initiated. 1- the port to use can be sent by the client 2- the client request the server to send the port to connect on. Since you are behind a firewall, method one would not work. You are thus forcing it to use method 2 by turning "passive mode" on. Hope this helps, Navin J On Sun, Mar 2, 2008 at 7:47 PM, Monah Baki <mbaki@xxxxxxxxxxx> wrote: > Hi all, > > I am testing the following scenario > > client --- IWSS (Redhat 4 ES) --- Squid (FreeBSD 6.3) --- Firewall > (OpenBSD) --- Internet > > IWSS has the squid as its upstream proxy, and everything works like a > charm except FTP > > When I try to access thru the browser a ftp site, I get the following > error: > > An FTP protocol error occurred while trying to retrieve the URL: > ftp://anonymous@xxxxxxxxxxxxxxx/ > > Squid sent the following FTP command: > > NLST > > and then received this reply > > Use PORT or PASV first. > > Your cache administrator is webmaster. > > > > I have another test scenario using the same hardware as above > > client --- Squid (FreeBSD 6.3 running dansguardian) --- Firewall > (OpenBSD) --- Internet > > I have no problem with FTP using this scenario. > > > > Thank you > > > > > BSD Networking, Microsoft Notworking > > > >
