Re: [tor-relays] Checking a bridge
by Gary Anderson 13 Nov '13

13 Nov '13

I have the same worry as Martin. I set up a bridge on AWS 2 weeks ago by following the instructions here https://cloud.torproject.org/ and choosing a bridge image for Ireland. Setup went well, log files on startup tell me my bridge contacts the tor network, and I checked I could use my bridge by explicitly configuring it in a tor client. But the traffic I see in arm is very small (around 100 MB / week) compared to what I observed when I tested a tor relay (over 2 GB in a week-end). On the other hand, I didn't find my fingerprint in Globe. Is there something wrong or can this be a normal situation that happens sometime ? Do all fingerprints end up in Globe ? T.

Traffic in port 9050 in a relay (denial of service attack?)
by jj tor 13 Nov '13

13 Nov '13

Hello all, I've set up a tor exit relay (0.2.4.17-rc, debian testing) on a VPS, and it's running well (about 20Gbs/day). But a lot of traffic (about 50%!) is using port 9050 for incoming connections. It's something more than random scans. Because I am worried, I've run tcpdump on this port and the packets length is about 50-60 bytes long. It seems like DOS or flood traffic: external ip tries to connect and my server refuses (RST, ACK), each time. My OR port is 9001, and, of course, SocksPort = 0 in my torrc. Do you think something is wrong with my relay? Why that traffic if my only tor port is 9001? Should I block that traffic using iptables?

Does TOR need TUN/TAP
by Sebastian Pfeifer 12 Nov '13

12 Nov '13

Hello! A short question I didn't found in the FAQ or with Google: "Does Tor (as an exit node) need a TUN or TAP device"? I am a poor pupil and with my provider servers without TUN/TAP (VRS) are 1€ cheaper per month than the ones with (KVM).

Of course such a list goes out of date faster than a phone book. That is another reason that using a list is an exercise in futility. Even more thought required to see that. Thus it would be hit or miss to try to access their website using Tor. If they do not respond to a suggestion that they learn more about Tor, a better choice is either to move on to a competitive website or to move our relay (exit or not) to a different IP address. Those options are already on the table in this thread.

exit and skype
by Jan Hendrik den Besten 11 Nov '13

11 Nov '13

Boy, now I am in trouble... I run an exit node from my home address for a few weeks now, but my gf starts complaining she cannot use Skype anymore to chat with her mum. I understand Microsoft blocks all tor exits from accessing Skype. Is there anything I can do except converting the exit into a relay? --

Tor relays and exits exposing Privoxy publicly

Relay-Bandwith
by Oliver Schönefeld 09 Nov '13

09 Nov '13

hey folks i'm having some issues with my bandwidth... my ISP is offering 50 Mbps downstream 10 Mbps up, so i thought i'd share 20 Mbps max and 15 Mbps avg (respectively 2560 KBps max and 1920 KBps avg) in a inner tor-relay. so i put the latter vaues in the bandwith-limits tab of the sharing options in vidalia with the download speed set to custom. However the tor metrics indicate an advertised bandwith of 317,44 KBps and the worldmap of vidalia even shows just 20 KBps :( So my question is now: Can this be improved and if so, what should i do about it? Or is this maybe because the relay isn't even up 24 hrs and the bandwith will level in somehow later? thx 4 any advice in advance, 1v3ry

Same boat but with two woman on two continents and both use Mshit and there is not a chance in the world that they will ever ever ever get jitsi, linphone, Ekiga or any of the other joke excuses for a Skype replacement going. Until there is a non-MS solution that lets non-techies use a service like that from behind NAT they are a HUGE waste of developer's time not to mention consumers. Take a look at the Ekiga mailing list, makes the problems people have with tor relay's seem like child's play. It is almost pathetic listening to them try to help people who WILL NEVER manage to get one up and running. It is a joke. My VPN blocks Skype. I tried hard to get rid of it but it is just not possible unless it's another geek that you are talking to. Complaining to MS or Apple can hurt actually, in the hopelessness area. May end up hanging yourself after trying to talk to them.

How to install Tor on Ubunt 12.10?
by The Maker 06 Nov '13

06 Nov '13

I want to run a relay that starts every time I login to my machine. I went to the page that discusses how to add the correct PPA to Ubuntu but it stops at 11.10. Is this also the PPA I should use for 12.04 or is there another one? Many Thanks, The Maker

max TCP interruption before Tor circuit teardown?
by Gordon Morehouse 03 Nov '13

03 Nov '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello, I'm working on building support scaffolding[1] for Tor on Raspberry Pi and other small ARM single-board computers (SBCs). With the slower computers, sometimes too many attempts to connect to the ORPort (I am almost positive as part of TAP circuit building, but not *really* sure) can eventually cause Tor to consume more physmem than available and cause the oom-killer to kill Tor. Also, depending on the crappiness of the user's router, it's effectively a SYN flood, and can crash or impair consumer routers. My solution, so far, is to define (through trial and error on a per-machine basis, since [1] is only officially supporting 3 SBCs right now) limits on how many SYNs may be sent to the ORPort and the DirPort per second. This is done with iptables. I experimented, tuned the parameters and watched traffic for weeks and came up with a pretty good set of limits for a 950MHz Raspberry Pi: 4 SYNs/sec burst 10. (For those about to say the Pi is thus too slow to be used as a relay, it's quite capable of relaying *at least* 2.5Mbps, but *not* when it's getting SYN flooded.) So, sometimes hosts exceed this limit. Once the limit is exceeded, my current strategy is to use iptables REJECT to send an ICMP Service Unavailable (or whatever it's called, sorry no coffee yet) back to the hosts that triggered the filter. This is on a per-SYN basis. After watching the data, I noticed that some hosts just try to connect once or twice, or try to connect (during overload conditions) at reasonable intervals of tens of seconds to a few minutes. Other hosts will quadruple-tap the ORPort with SYNs, four in a row, and otherwise be much more aggressive with sending SYNs. I'm currently testing fail2ban[2] as a way to ban aggressive peers by changing that iptables REJECT to a DROP for a short period, in order to accomplish two things: 1. Encourage them to knock off their bad behavior (i.e., go away for a little while). 2. Free up CPU time, RAM and bandwidth because we don't have to construct and send ICMP packets to banned peers. Currently, if a peer violates the 4/sec burst 10 SYN limit more than 5 times in 60 seconds, that peer will be banned for 90 seconds. I'm trying to trim this down to the minimum that will protect the relay, and 90 seconds is a guess given some of my fears, read on... During an overload condition, my primary priority is to protect the relay, but of course I wish to do so with as little disruption to the Tor network as possible. So, here is a potential problem with my approach that I can think of, which could degrade service (mildly, for a few end users) on the Tor network. First, during a SYN flood type overload, some peers which have *existing* circuits built through the relay and are sending SYNs as normal traffic, will stochastically get "caught" in the filter and banned for a short time. If these hosts already have circuits open through the relay which is overloaded, I would prefer to preserve those circuits rather than break them. My defensive strategy versus overload here is to throttle new circuit creation requests, *not* to break existing circuits. So here's the $64,000 question: If a tor relay has a circuit built through a peer, and the peer starts dropping 100% of packets, how long will it take before the relay with the circuit "gives up" on the circuit and tears it down? I want to set my temp ban time *below* this timeout. Thus, unlucky peers that were caught in the filter and have circuits already built through the relay they will experience a brief performance degradation, but they won't lose their active circuits through the overloaded relay, and in the meantime hopefully the overload condition is becoming resolved. Is there such a timeout? There must be. Can someone tell me what it is? Or, is there a better way to protect low-resource machines (slow CPU, 512MB RAM) against the SYN flood "circuit creation storm" conditions which occasionally arise on the Tor network? Again, I must reiterate, machines with specs like these can be very good relays for home broadband users. The true goal of my project[1] is to build a set of software which enables a "plug and forget" relay for home broadband users that costs well under $100.

Re: [tor-relays] dynamically adjusting bandwidth
by starlight.2013q4＠binnacle.cx 03 Nov '13

03 Nov '13

>The question is, should I put in an adjustment for >'MaxAdvertisedBandwidth' during the backup window >or make any other change to advise remote relays to >de-prioritize the node for the duration? Another unanswered question now understood: As a consequence of a simple parameter tweak, Vidalia buggily zapped (for the second time) the relay configuration and turned off relaying. Quickly restored 'torrc' and restarted the relay, but noticed that the getinfo dir/server/authority observed bandwidth value (third of three) was zapped to a low value for about an hour. This had the effect of causing four out of nine authorities to remove the Guard flag and almost resulted in a consensus "not Guard" state. So the answer here is definitely DO NOT lower 'MaxAdvertisedBandwidth' during intervals when 'RelayBandwidthRate' is reduced for events like offsite backups. Doing so will probably cause the Guard flag to be removed when it is present. The only possible exception would be if one has insane amounts of bandwidth and the lowered value is still quite high. Seems unlikely that 'MaxAdvertisedBandwidth' has any immediate effect on the selection algorithm is only averaged into consensus bandwidth gradually, so probably it's best to not make temporary reductions.

These nodes run a special relay control client that accumulates and analyzes bandwidth reporting by other Tor nodes via "signal" updates from a daemon control channel. Think they are called 'bwauth's. The value can swing wildly, but appears that the pattern is sinusoidal with an average close to the true bandwidth available from a relay. After a few days the swings in the value seem to dampen somewhat. This "consensus bandwidth" value appears to be what is used by the client nodes' relay path selection algorithm. getinfo dir/server/authority This appears to the observed bandwidth calculation derived from local node statistics. Is much more stable and accurate, but is "informational" and is not used in the path selection algorithms.

Cisco ASA
by starlight.2013q4＠binnacle.cx 31 Oct '13

31 Oct '13

For anyone running a Cisco ASA between their 'tor' relay and the Internet, some potentially useful info: The default ASA connection timeout is short and often results in 'telnet' sessions through VPN tunnels getting whacked. So one might add timeout conn 48:00:00 to a config to mitigate that issue. However a busy 'tor' relay instance will rapidly accumulate large numbers of dead connection table entries due to loss of FIN packets from flaky corners of Internet. I'm not 100% sure about this, but it seems these dead connection table entries can impair the formation of new connections, not to mention the obvious potential for excessive memory consumption on the ASA. The solution is: access-list tor-class extended permit tcp any host X.X.X.X access-list tor-class extended permit tcp host X.X.X.X any where X.X.X.X is the 'inside' server running 'tor' class-map tor match access-list tor-class policy-map outside class tor set connection timeout idle 0:06:00 As 'tor' sockets have a default KeepalivePeriod 300 any connection with an idle time of more than five minutes is a dead duck and can safely be removed. Checked this out carefully. The comment above was inspired by a seeming performance boost and increase in connections observed after the change was made, not by direct traffic analysis. Could be coincidental. The way to verify it's working is with the show conn addr X.X.X.X long command, which includes the idle timeout associated with each connection. If one has other services running on the same box as 'tor', it might be necessary to adjust the 'access-list' to take them into account.

Yeah. Not saying I see a good way to do it. Not really asking for it. Whiny, IDS-noticed, almost nuisance-type complaints are the only ones we've gotten. The complaints aren't even describing successful intrusions. Sucks if these whinebucket type of complaints are making it harder in real world terms for people to host exit nodes.

What he said. No DMCA so far but, one thing I keep getting is complaints about "SQL injection attacks". Apparently snort or other IDS picks this stuff up and emails the abuse box. Some but not all of the complaints are automated. It would be nice if something could detect these attack signatures on the internet-bound packets from our exit node and drop them. With trends as they are, we'd see zero abuse complaints, if there were a good way to do that.
