6/24/2023 0 Comments Windows 10 ftp server not working![]() ![]() If you can't get a smarter firewall, then you'll have to stick to the "open a bunch of ports" option (or switch to a protocol that doesn't need to open a bunch of random ports like ssh's sftp). You'll probably still want to force passive mode since some people don't know how to configure their FTP client properly and nearly everyone is behind a broadband router/firewall these days. This can often fix NAT addresses as well (when the firewall is also handling the NAT). The firewall will read the traffic on port 21 and open whatever port your server wants open. If you're not using SSL, the best answer is to see if you can get your firewall to do protocol inspection for FTP. If your server is using NAT you'll also need to set up the proper IP address for the server to advertise to clients, most obey whatever the server provides as the passive mode connection string and if the server thinks it's 10.1.1.1, that's what it's going to tell the clients. If you're using SSL, the only answer is to open a range of ports (say, 10000-11000) on the firewall and configure your FTP server to force Passive mode and use that port range. your server is behind a (dumb, or else SSL-blocked) firewall and is trying to use Passive-mode FTP.your client is behind a (dumb, or else SSL-blocked) firewall and is trying to use Active-mode FTP.Theres a good site on FTP with example logs here. To get real information on why the connection is stuck, you're going to have to use a client that logs all of the protocol commands to see what's really happening. Ive used Network Monitoring tools to try and see what ports it is calling but I cant figure that out. I believe my FTP client is using some long range port number(s) that are potentially blocked by one of my two firewalls. I have also opened those ports on my AWS (Amazon) firewall. I have ports 20, 21 open on my Windows firewall. ![]() This leads me to believe its a Firewall issue, (or even an IIS7 issue?) but I am unsure what ports I need to open? If I specify the "localhost" URL, I do not get the error. ![]() If I specify my full FTP URL, I get the hanging error. Here is what bothers me.if I use DOS FTP commands, I can login and use the "DIR" command only if I use "localhost" as my address. I can remote desktop on to the server and through DOS commands I can login rather easily.īut if I issue a command like "DIR", it hangs with:Įverything I have researched and read points to Firewall ports and/or Passive/Active mode settings. I am setting up an FTP server on my Windows 2008 server (R2).Įverything appears to be installed correctly but I am having trouble using an FTP Client to login to my FTP server. ![]()
