Hi,

I'm trying to build a ftp-server which delivers tv-programs from my computer in Finland to the computer I have in Spain. My purpose is to use remote connection to Finland to record programs, and then download them by using ftp-client program.

Correct me if I'm wrong, but computer in Finland needs:

tv-card
Ftp-server
static ip

Computer in Spain needs:
ftp-client

I think the question is, how do I configure my zyxell adsl modem (with NAT and Firewall based on port checking) in ftp-server and my the clients zone-alarm so that not every hacker can get to the ftp-server? Clients modem is bridged.

I obviously can't configure my Spain ip-number to the modem, because it's not static. Can I some other way identify to the modem "who is calling". Modem must also let windows remote control through? I need to also open some port-numbers for ftp-connection...

I think what I need to do is to open port 21(for command) and 20(for data) connection to the modem in Finland? To the clients zone-alarm firewall I need to open port > 1024 from Finlands ip-address? And then I put some password for the ftp-server? right?

If somebody would have some information concerning about this, I would appreciate it :)

Thanks for advance

Juha

You don't need a static IP address, you can use a service like DynDNS to find the server.

As far as security, I'd use a decent FTP server and complex user name/password combinations. I like FileZilla, and it's free. There is lots of documentation on setup of the server, check the FAQ on the page listed above.

Ok,

This Dyndns was new, never heard before, thanks :)

I actually planned to use FileZilla.

What about those servers port-numbers 20/21, were those ok? Were there any other possibilities in clients FW than to open all the ports that are bigger than 1024? Isn't that kinda risky, even then when clients firewall is configured to allow connections just from this specified ip?

I'll check the FAQ

Don't use FTP, use SCP or at least SFTP.

Cygwin includes openssh server for windows. Run that, restrict everything to TCP 22.

File transfers will be tunneled & encrypted inside the SSH payload.

Filezilla is an SFTP server.

I would think that it would do the job properly if it claims support for SFTP, right? Do you know that it doesn't work properly?

Ahh, I guess Filezilla does real-live SFTP now. Before it was just ftp over SSH. Data channel was still just like pasv FTP.

Having said that, it loooks like filezilla for windows is SFTP client only.... ? You'll still need OpenSSH for the server side.

Maybe I misread, I thought it was also a SFTP server. You're right if that's the case.
