Sustained large spike in outbound traffic - what might be going on?
by David Tomic 30 Dec '15

30 Dec '15

Hello everyone, I noticed something a little bit "odd" on one of my exit relays recently, and I just wanted to ask whether anybody might be able to account for what was actually happening, and whether it's likely to warrant any further investigation? TLDR; I noticed a fairly significant spike - in excess of 30MB/s (yes, megabytes) - of outbound traffic compared to inbound. http://s2.postimg.org/cvfzqvrsp/graph.png It persisted steadily for just over an hour, until I noticed what was going on and restarted Tor (not the whole server, only Tor), at which point my traffic appeared to return to normal again. I have this relay running a a dedicated machine, with multiple physical NICs, and the ONLY thing which should be touching this NIC is my Tor traffic. Thoughts?

Very unbalanced inbound/outbound connections
by Jannis Wiese 21 Dec '15

21 Dec '15

Hi operators, for a couple of days, I see a little bit more than twice as much inbound than outbound connections on my (non-exit, non-guard) relay [0]. I have no real concern about this but I want to explain it to myself somehow. As my relay has the HSDir flag, I started looking at the statistics: The graph for relays with HSDir flags went down by approx. 500 relays in the past days [1], but that’s pretty much traceable to a lot of relays updating from Tor 0.2.6.x to 0.2.7.x (there’s a similar behaviour around Nov 23rd [2] where the updates started as well as around June 08th [3] where updates from 0.2.5.x to 0.2.6.x started). On the other hand, the number of HSDir flags was fluctuating quite a lot looking at the year up to now [4] which never had this effect on my relay. After all, looking at the graphs in atlas (as well in arm) shows no significant (= something like twice as much) difference between the inbound and outbound traffic - so I’m scratching my head now. Another open question would be if HSDir connections are considered as in- or outbound. Up to now, I held the HSDir flag responsible for the slightly higher outbound traffic… So, again: Still no real concern from my side (as my relay is running fine - if it would be an attack, I would be able to feel that, right?), but I would like to understand what’s going on. :-) Maybe one of you here has an idea about this or experienced something similar. To all of you an early “happy holidays”!

Allow user to provide feedback?
by Eric Hocking 21 Dec '15

21 Dec '15

Would it be possible for there to be a way for users to provide feedback on the current tor relay/server they are using? Ex: users submit feedback such as let's say "relay is slow" when another user uses the proxy, they could see the user provided feedback of the relay

IPv6 Only Exit Node
by Hans Wurscht 20 Dec '15

20 Dec '15

Hi I would like to operate an IPv6 only exit node. I.e. it's fine if tor relays through IPv4, but I want exiting traffic only through IPv6 (because I don't want my (only) IPv4 to be blocked, abused and such). The way I thought this would work is with the ExitPolicy set as below. But atlas says my IPv6 Exit Policy Summary would be "ExitPolicy reject *:*". Now I'm wondering if my ExitPolicy is wrong defined or if that's a bug of some kind. I'm running Tor v0.2.7.5 (git-6184c873e90d93b2) on Linux with Libevent 2.0.21-stable, OpenSSL 1.0.1k and Zlib 1.2.8. # No IPv4 exit, no exit to my own subnet, no exit to private network, no exit to link local ExitPolicy reject6 [2A02:168:4A06::]/42:* # Block my subnet ExitPolicy reject6 [FC00::]/7:* # Block private IPv6 ExitPolicy reject6 [FE80::]/10:* # Block link-local IPv6 ExitPolicy reject6 [2002::]/16:* # Block 6to4 addresses ExitPolicy reject6 *:25 # SMTP ExitPolicy reject6 *:119 # NNTP ExitPolicy reject6 *:135-139 # NetBIOS ExitPolicy reject6 *:445 # Microsoft AD ExitPolicy reject6 *:563 # NNTP over TLS ExitPolicy reject6 *:1214 # Kazaa ExitPolicy reject6 *:4661-4666 # ? ExitPolicy reject6 *:6346-6429 # Gnutella ExitPolicy reject6 *:6699 # WinMX ExitPolicy reject6 *:6881-6999 # BitTorrent ExitPolicy accept6 *:* # All else ExitPolicy reject private:* # Block private IPv4 ExitPolicy reject *:* # Block all IPv4 ## If set, and we are an exit node, allow client to use us for IPv6 traffic IPv6Exit 1 -- tor.x2a.ch | https://atlas.torproject.org/#details/6FAAD7CC7EBB008AEF2E5AE1BB9082CD8BD60…

expected IPv6 traffic for an exit relay
by Toralf Förster 20 Dec '15

20 Dec '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I opened my exit for IPv6 after Moritz encouraged us to do so here at this list. I do observe a traffic of 1-2 GB. for IPv6, IPv4 is always abound 300 GB/day. The exit is configure for 8 MB/sec throughgput (==20 TB/month). I do wonder, what are expected values for IPv6. Furthermore between 11th of August and 25th of September I observed a traffic of about 30-40 GB per day for IPv6 - but why only in this time frame ? - -- Toralf, pgp: C4EACDDE 0076E94E -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iF4EAREIAAYFAlZsQtUACgkQxOrN3gB26U6q3QD/X8RceaLv8uKKcUtcO1CbugCK f2nu+JG8xBVJe+kBFCYA/jSddQ7auahsc5YSmuqgJY1fzWu43xN5kWvGG89tyzxe =/91J -----END PGP SIGNATURE-----
