How can I run an ftp server? I have a cable modem connection and I wish to be able to access my files remotely. I have installed ftp serv-u and winip for IP translation. I am able to access my ftp server using local network but connecting to the external IP of my server, however it translates to the internal IP automatically under CuteFTP. But when I try accessing it using a regular dial-up connection it says "unable to establish connection". I am using winproxy as well and I have set receiving ftp connection and the ftp serv-u program enabled at port 21. Help...
How is the network setup? ie. does the server have a direct internet connection, or does it connect through a router/NAT box? If the latter, you will need to have some sort of port forwarding program installed on the router (maybe that's what winip is?????)
Hmmm. Seems like my ISP has blocked port 21 either for security reasons or to prevent users from running their servers. If I set any port other than port 21, I can get through. Now I cannot connect my data socket. Understandably by default we have port 21 as connection socket and port 20 as data socket. I cannot connect my data socket now, because I do not know what port the data socket should be and what port I should enable in the proxy's firewall. Is it one less than the connecting socket or what?
The cost of running your own FTP server is very high: you need an always-on FTP server computer, then you need to install FTP server software. For this to be reliable, you need to take care of the security, which means you need to configure access permissions carefully and install OS patches periodically. Moreover, you need to backup the server and make sure you have redundant hardware. Then you need to have a good and reliable Internet connection.
The cost can be thousands of dollars, not including your time and efforts!
