I successfully installed Tor on my debian vps. Is there a way to connect my cell phone or another computer to Tor network using my vps? If there is a way, how should I set it up to work?
Well, the default
SocksPort is 9050 for non-Tor Browser tor installations.
That said, exposing a
SocksPort over the Internet would be a fairly bad idea (running open proxies is usually frowned upon), and accessing such a thing over the Internet would be an even worse idea, assuming you want any sort of privacy or security, as SOCKS4(a)/5 requests are sent unencrypted, so everyone in between your phone/computers and your VPS can see your destination.
If you really want to use a tor instance on a VPS that you control as your first hop, make your VPS into a Bridge, and instruct Tor Browser/Orbot/whatever to use said Bridge.
