So I'm trying to setup a home FTP server, and I've got a host registered with dynDNS. I've followed [URL="http://www.makeuseof.com/tag/set-freenas-server-access-files/"]this tutorial[/URL] exactly with no luck. SmartFTP tries to connect to my router's external IP, so I know dynDNS is doing its job, but it ends up telling me that there was no response. Halp?
Port forwarding set up to go the computer with the server setup?
Ports 22 and 80 are forwarded for the IP of the server (192.168.1.169)
FTP is usually on port 21 And some ISPs block common ports like 21/23/80
If your in the UK, no ISP will block any port.
[QUOTE=IpHa;37309226]FTP is usually on port 21[/QUOTE] Unless it's sFTP (Which apparently Smart FTP supports), but it still would be wise to forward 21.
It is in fact sFTP, but I forwarded 21 anyway. Here's a brief overview of what's happening: dynDNS host is nick.homeftp.net dynDNS account username is nick (same as host) ports 21, 22, and 80 are forwarded with server IP 192.168.1.169 logging into FTP with [EMAIL="nick@nick.homeftp.net"]nick@nick.homeftp.net[/EMAIL] on port 22 no dice :( Also my router has a feature for dynamic DNS, and I've added my info into it.
Just a stupid question on my part, but do you have SSH?
I do indeed. I just changed hosts, though. I'm guessing dynDNS takes a while to update that stuff.
I just checked it with nmap and I'm not seeing those ports open: [code]Starting Nmap 6.01 ( http://nmap.org ) at 2012-08-19 15:11 EDT Nmap scan report for nick.homeftp.net (107.194.116.122) Host is up (0.15s latency). rDNS record for 107.194.116.122: 107-194-116-122.lightspeed.frsnca.sbcglobal.net Not shown: 999 filtered ports PORT STATE SERVICE 443/tcp open https Nmap done: 1 IP address (1 host up) scanned in 24.23 seconds[/code]
That's not the actual address, I was just giving an example. I can ping my hostname with a response... but something's still not letting me through on an ftp client.
Did make an exception in the firewall?
Yessir. If it was my router would I still be able to ping the host?
Starting to go a little insane here. I've decided to try and get it working on my PC first. Here's my checklist: dynDNS up and running (pinging the host works) [U]Router:[/U] Ports 21, 22, 80, 990, 3000-4000 forwarded on my router to my computer's IP (192.168.1.4) Dynamic DNS is setup like so: [IMG]http://i.imgur.com/5jDSZ.png[/IMG] [U]Filezilla Server:[/U] Listening on port 21 IP Binding is set to 192.168.1.4 Passive mode on ports 3000-4000 "Don't use external IP for local connections" box in passive mode settings is unchecked Added to Windows Firewall (public and private) Added user "nickzourdos" with access to specific directory [U]Result[/U] Status: Resolving address of zourdos.homeftp.org Status: Connecting to 24.x.x.195:21... Then it just times out.
Have you tried a different port?
Changing FileZilla Server's listening port to 22 and connecting to the same host through 22 won't even resolve the hostname. Wat.
I can confirm that those ports you've listed are closed to the outside world. Running a port scan via nmap reveals nothing. I'd say they're firewalled off. Turn off Windows Firewall, test with [url=http://www.yougetsignal.com/tools/open-ports/]a web port checker[/url] and then see if it's a software or hardware firewall giving you grief. (Note that you can have exceptions through your hardware/router firewall and still have it accept ping requests) [quote]Starting Nmap 6.01 ( [url]http://nmap.org[/url] ) at 2012-08-22 10:42 EST NSE: Loaded 93 scripts for scanning.

I think Charter is my problem. Apparently they're notorious for blocking ports that allow you to have any fun.
I have charter and the only ports I know are blocked are 25 and 80. I just checked 21 and 23 and they're not blocked.

[QUOTE=MTMod;37389951]Where do you live? I've done pretty much everything I can other than putting my computer in the DMZ.[/QUOTE] Kalamazoo, MI so we should have similar service. Nmap still says you have nothing open, so it could be a firmware bug on your router. If it's supported by dd-wrt you may want to try that.
I do see a firmware update available, but it always fails halfway through and says there's not actually an update. I'll manually update it soon. Also, you ever been to Olde Penninsula? Best pub in Kzoo.
I recently built my own home server, and now it works. I hope it will help: Start server Open port(default FTP port is 21) Make your FTP server program to get through Windows Firewall TEST your open port on "canyouseeme.org" if it can see your port 21, CONGR! If not, again open firewall, disable it. Check again, if it works, enable firewall again, and make firewall to allow port 21. If still CANYOUSEEME.ORG cant see your port 21, check ^ again, and try to check your modem settings, to see if it blocks external ftp connections. If still no success, feel free to contact me, i would be happy to help you out. PS. your if you want to make port 80 work, first you need to change your modems login port.(i changed it to port 8080)
