Re: [tor-relays] Does TOR need TUN/TAP

Hello! A short question I didn't found in the FAQ or with Google: "Does Tor (as an exit node) need a TUN or TAP device"?

It does not require tun/tap; Tor runs over and exits through TCP sockets exclusively, last I checked. However:

servers without TUN/TAP (VRS)

If by this you mean something like OpenVZ or a similar "container" implementation, such that your node shares kernel memory with other containers, beware of limitations on the number of sockets you can have open at once. Tor keeps a large number of connections open simultaneously, and if it is not permitted to do this it may not function properly.

Hope this helps.
