Raising AuthDirMaxServersPerAddr to 4?
by Roger Dingledine 04 Jun '19

04 Jun '19

Hi folks, I've been talking to a longtime exit relay operator, who is in the odd position of having a good 1gbit network connection, but only one IP address. He used to push an average of 500mbit on his exit relay, but then the HSDir DoS flatlined his relay for a while (!), and now, perhaps due to the bwauth variability, his exit relay only recovered to maybe 200mbit. He is running a second exit relay on that IP address, but also perhaps due to the bwauth variability, it hasn't attracted much attention either. The real answer is to fix the bandwidth measurement infrastructure. But while we're patiently waiting for progress there, I've been thinking to raise moria1's AuthDirMaxServersPerAddr to 4, i.e. to allow 4 relays per IP address onto the network. I don't think it would significantly increase our risk due to Sybil attacks, whereas there is a clear benefit in terms of some more 100's of mbits of good exit relay capacity. I will propose this change to the dir-auth list in a bit, but here is your chance to point out surprising impacts that I haven't thought of. Thanks! --Roger

Should we allow matrix.org users on tor IRC channels?

Hi all, JeremyRand has asked us to allow matrix.org users on the tor IRC channels on irc.oftc.net. matrix.org users are rejected at the moment, because they are not registered with OFTC. For details, see: https://trac.torproject.org/projects/tor/ticket/30717 T -- teor ----------------------------------------------------------------------
