This is easy to set up now, but - there's no way to advertise it to clients. - -New descriptor syntax: - - We add a new line in the router descriptor, "or-address". This line - can occur zero, one, or multiple times. Its format is: - - or-address SP ADDRESS ":" PORTLIST NL - - ADDRESS = IP6ADDR / IP4ADDR - IPV6ADDR = an ipv6 address, surrounded by square brackets. - IPV4ADDR = an ipv4 address, represented as a dotted quad. - PORTLIST = PORTSPEC | PORTSPEC "," PORTLIST - PORTSPEC = PORT | PORT "-" PORT - - [This is the regular format for specifying sets of addresses and - ports in Tor.] - -New OR behavior: - - We add two more options to supplement ORListenAddress: - ORPublishedListenAddress, and ORPublishAddressSet. The former - listens on an address-port combination and publishes it in addition - to the regular address. The latter advertises a set of address-port - combinations, but does not listen on them. [To use this option, the - server operator should set up port forwarding to the regular ORPort, - as for example with firewall rules.] - - Servers should extend their testing to include advertised addresses - and ports. No address or port should be advertised until it's been - tested. [This might get expensive in practice.] - -New authority behavior: - - Authorities should spot-test descriptors, and reject any where a - substantial part of the addresses can't be reached. - -New client behavior: - - When connecting to another server, clients SHOULD pick an - address-port ocmbination at random as supported by their - reachableaddresses. If a client has a connection to a server at one - address, it SHOULD use that address for any simultaneous connections - to that server. Clients SHOULD use the canonical address for any - server when generating extend cells. - -Not addressed here: - - * There's no reason to listen on multiple dirports; current Tors - mostly don't connect directly to the dirport anyway. - - * It could be advantageous to list something about extra addresses in - the network-status document. This would, however, eat space there. - More analysis is needed, particularly in light of proposal 141 - ("Download server descriptors on demand") - -Dependencies: - - Testing for canonical connections needs to be implemented before it's - safe to use this proposal. - - -Notes 3 July: - - Write up the simple version of this. No ranges needed yet. No - networkstatus chagnes yet. - |
