Running a Tor Exit Node for Fun and E-mails
Regarding the saturation of free socket ports. I see that KeyWeb gives you 2 IP addresses per vServer (and IPv6 enabled, which I assume means a whole /64). Wouldn't it have been easier to configure Tor to bind to only a single IPv4 address and use the other one for administrative login? As far as I understand the Linux network stack, port exhaustion happens on a per-address base. So even if Tor (or anything else) exhausts all the connection ports for one address you should still be able to get back in via the other address.
