Re: FTP with Tor

Hi,

1) "the fact that an application speaks socks 4a doesn't mean the dns leakage problem is not present."

Oh. Can you perhaps explain the significance of socks4a for me? Why is it so important to Tor if it is not related to this DNS issue? Isn't the importance of Privoxy something to do with it enabling Tor to be used as a Socks4a proxy as opposed to a Socks4 or Socks5 proxy?

2) So, I think what you are saying is that if I input an IP address to the FTP client, instead of a domain name, then there will be no DNS issue cause it will of course not have to look up the corresponding IP address to the domain name - it already has the IP address! A good idea for sure. Now, how to get the IP address for a given ftp domain name? Could use Tor-resolve:

"a program that you run to resolve one single domain name to one sinlge IP address
using the tor network."

How do I run Tor-resolve? Still don't really know how to use the Tor-resolve functionality.

An alternative to Tor-resolve perhaps is to use netcraft.com - this site can, given a domain name, give you the corresponding IP address.

3) With FTP - is it best to use Tor as a 1) Socks4a proxy 2) Socks4 proxy or 3) Socks 5 proxy?

Thanks ever so much. I know that I must be trying your patience but Tor with FTP is a turning out to be a little bit tricky for me.
Best wishes,
Ben

Hi Ben,

as you said tor works fine with FTP (haven't tried though). If I don't
misunderstand the fact that an application speaks socks 4a doesn't mean
the dns leakage problem is not present. A word on tor-resolve (which I
haven't tried too): It's nothing you can "activate", rather a program
that you run to resolve one single domain name to one sinlge IP address
using the tor network. Given the case you want to upload thing to always
the same FTP server (assuming it has a static IP) you can use
tor-resolve to resolve the name of that server and put the IP in as the
host name in your FTP client. Now, if your proxy setting are set for
tor, everything should be fine because there is no domain name to
resolve (which would happen non-anonymous).

Cheers
