Re: [tor-relays] Middle relay still an useful contribution?



Note that a bridge is not guaranteed to be used. I've seen plenty of bridges, both plain-vanilla and obfs4, with or without IPv6, regardless of geography, that use only a few megabytes of bandwidth per month. Everything seems good in terms of connectivity yet there is basically just housekeeping traffic. Some bridges just seem to go ignored as entry points into the Tor network.

Not trying to dissuade you from running a bridge, just pointing out that that the bandwidth you want to donate to the Tor network may not be utilized. In contrast, I haven't seen a mature middle node that went unused.

I thinking about a bridge too. But which port is not censored in China?
I have read an article about the firewall of China. They doing DPI and
filtering all encrypted traffic. Obfsproxy should be a good choice. A
short test give me some experience for tor connections, but more traffic
inside as outside (asymmetric). I'm not sure that will work right.

A middle node need some days to get some traffic. An exit node is at
full power in some hours. The guard flag for the middle nodes came after
2 weeks, I think.

Can someone give me a proposal for a bridge port that is usefull for
censored countries?

Hi Ortez,

Not right now. I know bridges are needed for users in countries like china and so on, but are they used much?
Yes. A bridge will utilize your server's bandwidth just as nicely as
an exit relay would. Someone recently posted impressive diagrams to
illustrate this, but I cannot find them now. In addition, please try
to install a pluggable transport such as obfs4 to make your bridge
more censorship-resistant!

Thanks for asking!
