 True.  And veering OT, but have you tried mosh yet?  It's ideal for some
 situations over Tor, or where the client changes connections often.

No, I built something for that situation myself around the same time
and am just rewriting it. (Just a transport, no terminal prediction,
with the intention of also using it as a transport plugin for tor
bridge access.)

Btw. if mosh 'works over tor' you may want to check if you're not
just sending the UDP around tor.

[tor-relays] VPN termination on relays

2013-07-31 Thread grarpamp
 Mosh is great, but it still relies exclusively on UDP, right?
 So no over Tor...

Somewhat related to things that don't work via exits...

So who wants to offer VPN termination as part of their
exit service? User tunnels VPN to you, you give back
a bound port, or a natted 10 address, somethings of
that sort.

Re: [tor-relays] What to do about port scans?

 I know I can limit the rate of connections using iptables.  What's the
 consensus on this?  Is this considered advisable, or a breach of

You should not interfere with traffic other than the means you get by
Tor, ie. block IP/Ports.

If your ISP has problems with port scanning you should find a better one. :)

[tor-relays] Diagnosing relay unresponsive messages

2013-07-31 Thread Gordon Morehouse
So, I've got my relay back up on a Raspberry Pi and I'm working on
figuring out the optimizations I made to it, and continuing to tune it.
 Out of the box these machines have some difficulty even offering a
couple Mbps, but they can be greatly improved.  I will post all details
when done.

I see a fair amount of this, much less than after some tweaks, but it
still happens:

 20:27:36 [ARM_NOTICE] Relay resumed [1 duplicate hidden]
 20:27:30 [ARM_NOTICE] Relay unresponsive (last heartbeat: Wed Jul 31
20:27:19 2013)
 19:50:57 [ARM_NOTICE] Relay unresponsive (last heartbeat: Wed Jul 31
19:50:4


This often happens at the same time as 'arm' (the monitoring program)
may stutter, fail to render a few frames, then 'catch up' or redraw the
screen.

I'm trying to figure out what's going on so I can prevent it.  It
doesn't always correlate with traffic - it happens more often when
there's more traffic but can happen even with very little.  Tor is
taking about 10% RAM, there's plenty free, and load is under 1.0.

Best,
-Gordon M.
