Re: [tor-dev] Tor HS DHT Research

Thanks for your feedback.  It appears that it isn't possible to game the uptime since this commit:

https://gitweb.torproject.org/tor.git/commit/f7a3cdc8f27c2306cf06d742af63846c82ebdc56

Thanks for the pointer to shadow.

All the best
Gareth

Dear all

Sorry if this is the wrong list (please tell me if it is).

I'm undertaking research into the tor HS DHT and have a couple of questions.  I know at present, a node must be on for 25 hours to participate in the DHT; however, periodically I wish to make small code changes to Tor and restart the node (aka fairly instantly/within minutes) but this causes me to lose the HSDir flag.  So my questions are:

1) Is there anyway to restart Tor without losing the HSDir flag?
2) Is uptime self reporting - e.g. is a node's self reported uptime trusted or is it obtained elsewhere - I couldn't find the answer in the code.  I guess what I'm getting at, is can I fake the uptime to get the HSDir flag?

Best
Gareth
