What IPs does Torbrowser need?
by Martin Kepplinger 19 Mar '16

19 Mar '16

Hi Imagine a router that want to only whitelist the IP addresses that Torbrowser needs to work. What IPs would it need (for start up and browsing) ? * Guards * Authorities * HSDir flagged relays (?) and would such a whitelisting of IPs even work? At least I think DNS can be ignored as it is routed over Tor too. Any more thoughts? ps: please leave me in CC as I'm not on the tor-talk list. thanks!! martin

Bug #18580: exit relay fails with 'unbound' DNS resolver when lots of requests time-out https://trac.torproject.org/projects/tor/ticket/18580

unbound bogs down strangely, degrading exit relay
by Dhalgren Tor 19 Mar '16

19 Mar '16

Hit a repeat of an earlier incident: https://lists.torproject.org/pipermail/tor-relays/2016-January/008621.html message from tor daemon is Resolved [scrubbed] which was already resolved; ignoring About 5400 of these messages over 37 hours, during which the relay dropped down to 30% of usual load and did not work for Tor Browser when the exit was specifically set. Unlike the earlier incident, DNSSEC was disabled. Probably the IP address for root-server H was incorrect because it changed in December and 'unbound' was built in September. Just installed and configured the current 'named.root' hints file. Both "iterator" and "validator" modules were loaded, though validation was disabled. Changed the config to load only "iterator". Unbound 1.5.4, tor 0.2.6.10. Running 164 days. If I see this again I'm planning to attempt purging the 'unbound' request queue with unbound-control dump_requestlist >reqlist.snap unbound-control flush_requestlist and if that doesn't work, bouncing 'unbound' without stopping the 'tor' daemon. Interesting stats were recorded, starting with the good pre-incident entries: Mar 11 05:53 notice: sendto failed: Invalid argument notice: remote address is 0.0.0.1 port 53 ...repeated 4 times Mar 15 17:45 server stats for thread: 1029423 queries, 415824 answers from cache, 613599 recursions, 0 prefetch server stats for thread: requestlist max 132 avg 22.5692 exceeded 0 jostled 0 average recursion processing time 4.070100 sec Mar 16 05:46 Resolved [scrubbed] which was already resolved; ignoring Mar 16 17:45 server stats for thread: 1162172 queries, 287662 answers from cache, 874510 recursions, 0 prefetch server stats for thread: requestlist max 421 avg 198.684 exceeded 0 jostled 0 average recursion processing time 25.833646 sec Mar 16 21:08 notice: sendto failed: Invalid argument notice: remote address is 0.0.0.1 port 53 ...repeated 4 times Mar 17 16:52 notice: sendto failed: Invalid argument notice: remote address is 0.0.0.1 port 53 ...repeated 4 times Mar 17 17:45 server stats for thread: 1078496 queries, 144557 answers from cache, 933939 recursions, 0 prefetch server stats for thread: requestlist max 459 avg 296.668 exceeded 0 jostled 0 average recursion processing time 40.621863 sec service stopped (unbound 1.5.4).

This is why I removed the AccountingMax setting and reduced my RelayBandwidthRate to 500kb/s and RelayBandwidthBurst to 700kb/s. What concerns me is that while running arm in graph mode, I rarely see the bandwidth rate steadily flow around 500kb/s. With a 3tb bandwidth limit per month, following your recommendations, would you recommend that my AccountingMax be set to 55gb per day up and down and turn off RelayBandwidthRate and RelayBandwidthBurst? This will probably mean that the bandwidth will be used up within the first 10-12 hours of each day and my relay will be in hibernation for the remaining portion of that 24 hours. This hibernation period appears to affect the uptime statistics, which means my middle consensus numbers will drop as a consequence. I'm trying to figure out what's the secret sauce here to keep the relay running 24/7 and stay within my 3tb bandwidth limitation. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (MingW32) iQIcBAEBAgAGBQJW5yi+AAoJEH1gNwhiMDZubTgQAJuj6EdfLZsyPsLxfeiLA2nh w52jJLO3yXg+InJ4IzoSaHzbXsqdUuSmj7RxOsgTr9K1xflX3XkdNmlWYkhs005F JNMGyglnOb3LlSbJ9fxspZH1KOhwJwy9ZJrHGRqVRXrAC7VBMpJ016TEcFNL3daL J98LhZuyN5Iecm0k9LhuxoZ0YfnCc03qpkUJDMiM0khsXfoesFWd+Zdss/Igj2aC mVcE+BMKvO8gHATdVytvHvqqZ07unIAV6mRkw/c/NBqRh07xX6qEJwoDANCEvfS6 7NGQZpgEVWw2lT2GPj5T4WGmEPN6CAfCJTE7fJG1IA1j4iLNgHwRM7kKxQpFWpVa CAwE8wgc9BxFYCVg8Kzjr/PDJO7mNLFRH3yXXJ9dTo6qS+GRxdZEYTH6FaNc9ERP W9/hnv18bo0IuQ+o8+sMtzDbAbyyPXDeSbx2qHOzxuTJkzLPkq2t8W2HX5kiurZ8 MIkdkJH+bc71EwV1YBzb/Ca4/kdqTRqEMJzXFtn8wq6fa1uRxDC1S7Su374y4fTy C1OmTfURhKhK39yVFVJrKqINsgE1GQnKikE2DCMlbrp+IFaItrDOg+gx81mO7WkK /KbpxnKJotLxIxBX12j0T6CYyGKQio6SSTbI0iObsXJNpEkQCX+jPp3GDDcWPzlK p/XtNor8MXQS1u96hpwP =z+T6 -----END PGP SIGNATURE-----

relay maintenance without losing consensus weight?
by Zwiebel 09 Mar '16

09 Mar '16

Hello, is there a way to shut down Tor relays for a short time without losing consensus weight or bandwidth? Last week I installed a newer Tor version and added more RAM and now my relays lost a third of their bandwidth. Last time I've upgraded the hardware was in January and the relays didn't fully recover from the downtime in the last two months. I'd gladly provide 200Mb/s+ of relay bandwidth if I could, but Tor won't let me. - Zwiebel

Thanks for adding relays! Maybe set a contactinfo? (Whenever a university adds an unusual amount of relays it reminds me of the CMU case though.) http://article.gmane.org/gmane.network.onion-routing.ornetradar/1030 (I'm not implying they are doing anything bad)
