Sebastian
I realize that
It seems weird to put that as the first recommendation though
atagar
~it's listed as the first 'fix' becasue its the one that most directly resolves the issue (it's saying 'information X will be out of date unless Y') which strikes me as being accurate and not exactly pushing people into the extra info option unless they care about the connection data
Sebastian
Do you detect that the information actually is out of date?
or that the relay isn't used as a client?
Otherwise you might be pushing people into setting that option without them ever needing to.
atagar
I check that DirPort isn't set but not aware of how to detect if it's being used as a client (suggestions?) and I'm unaware of an option for getting the descriptor's age (that would be nice to have though...)
Sebastian
(I'm asking this because tor26 is still heavily overloaded, and a new authority will likely join the network soon, and its operator is also worried about traffic consumption
I'm not sure if either is possible, that's why I asked ;)
atagar
Not that I'm aware of (though could probalby be detected indirectly such as by the addition of new client circuits). I can reduce it to notice level if you'd like.
Sebastian
Well, I'd just reverse the order or leave out the uselessdescriptors thing completely
But feel free to keep it like that, I guess. Not that big a deal anyways.
atagar
I doubt that most relays are consistently used as clients so I'd rather not swap the ordering - the useless descriptors option is generally the best solution
Sebastian
hm. I think the best solution is that people who care just get their act together and provide a dirport
;)
         

atagar
heh, agreed :)
Sebastian
or they realize that whenever they look at arm they're also using Tor as a client, so it's fine. In any case, /me goes to paint the bed instead of the bikeshed.
atagar
don't follow... "whenever they look at arm they're also using Tor as a client"?
Sebastian
I mean that if they happen to care about what arm shows them, they could just use Tor as a client.
atagar
an option I'd like would be a manual refresh - provide a notice that the descriptors are out of date and give them the option to manually fetch them if they care

mikeperry, arma: Torbutton xpi files in tpo/torbutton/releases/ are signed with Mike's key DDC6C0AD, but that is not included in the reference list on tpo/verifying-signatures.html.en.
Nor could I find a reference to it on fscked.org.
(I did successfully download the key from the MIT server and verify the sig's.)
arma
sure enough, that's true.

gui1
hello i need some help here with installing tor, it is giving me this error on firefox: The proxy server is refusing connections
Firefox is configured to use a proxy server that is refusing connections. (im using ubuntu)
katmagic
Is Privoxy/Polipo running?
Ubuntu packages are with Privoxy, right?
arma
katmagic: it's worse than that. if you install the ubuntu tor, it will draw in privoxy. then you install polipo, change its config, try to start it, and polipo silently fails to start because privoxy is already up.
gui1: the fix is probably to apt-get uninstall privoxy, then /etc/init.d/polipo restart
katmagic
Why is it like that?
arma
dunno. nobody's fixed it?
it's hard to fix it, given that the older debs are older
if you start with the new deb, it's ok
gui1
thanks everyone, the problem was simple: polipo wasn't running
is there a way to start polipo when i click on tor button for firefox?
arma
there is, but it's very hard to do. instead, you should just set polipo up to start at boot.
it will start at boot if privoxy isn't also set to start at boot.
gui1
privoxy is not installed in my machine
arma
ok
wonder why polipo wasn't running then.
perhaps it was, but you hadn't reloaded it with the new config?
(you *did* change the polipo config as the instructions said, right?)
gui1
yes
katmagic
sudo /etc/init.d/polipo restart
gui1
but when i try to restart polipo with "sudo /etc/init.d/polipo restart" it tells this: Restarting polipo: /usr/bin/polipo already running -- doing nothing
polipo.
         

arma
that seems kind of silly.
really silly, actually. that's the point of restarting.
what polipo version?
gui1
lets say i put : sudo /etc/init.d/polipo stop, and then sudo /etc/init.d/polipo restart it will still output that
version 1.0.4.1-1
arma
huh.
perhaps it has a pidfile somewhere?
if you /etc/init.d/polipo stop, does it actually stop?
gui1
yes it des
does
arma
look at /etc/init.d/polipo and see what it actually does in the 'restart' case
gui1
is it possible that i have two different polipo installations?
arma
it's possible. how did you install it?
gui1
well i didnt :S
it was already installed from ubuntu
i just edited the etc/polipo/config
arma
ok. probably it got installed when you did apt-get install tor, then?
are you using deb.torproject.org?
gui1
yes
arma
ok
probably you have only one polipo then

or: How do I remedy this problem please?[...]
gui1
lol, yes i may probably have done something wrong, im very new to linux
arma
when you sudo apt-get remove privoxy, what happens?
gui1
now it works so everythind is fine
lets see
0 upgraded, 0 newly installed, 0 to remove and 49 not upgraded.
arma
ok
(you might want to try an apt-get upgrade, it sounds like)
gui1
something wierd was happening but now the stop start and restart works again
arma
or whatever gui program you like for keeping your system up to date)
gui1
you may want to have a look at what i did in terminal : http://paste.ubuntu.com/437539/
aaaaaah, im so stupid, i didn't put the sudo the first time!
arma
gui@linuxbox:~$ polipo
Established listening socket on port 8118.
this one is also bad
you were starting polipo as you, not as the polipo user
but, it looks like it worked out
next time you boot, you'll be able to learn what successfully starts, and what doesn't
gui1
ok, well thank you very much, im sorry to have made you loose ur time
arma
no worries. ...want to run a relay? :)
gui1
yes i'm heading to that part now
i just installed vidalia, and when i click on start tor it outputs an error : http://paste.ubuntu.com/437547/
im trying to set up a realy but vidalia doesnt get tor to start error log : http://paste.ubuntu.com/437549/

PeterT
why might tor crash when I close the firefox window?
dr|z3d
No logical reason for that to occur.
PeterT
well, I start tor
it opens Firefox with the https://check.torproject.org/?lang=en-US&small=1
and then I close that
and tor exits
dr|z3d
Are you using the Tor Browser Bundle?
PeterT
yse
*yes
dr|z3d
That's your answer, then. :)
PeterT
what's wrong with that?
dr|z3d
Nothing. It's behaving exactly as it should.
You might find the Vidalia bundle a better fit for your needs.
PeterT
ok
installing it now
PeterT_
thanks dr|z3d
but why do I get different identd reponses?
well, thanks anyway
PeterT
one more question, sorry
dr|z3d
In other news, google search is now offered over https. https://google.com
PeterT
does your information get logged when you bounce connections?
dr|z3d
PeterT: How do you mean?
PeterT
let's say I'm checking my email with tor
using gmail.com
will someone know that I am checking my email?
if my connection is using their tor?
keb
google will know
dr|z3d
Sure.
But since gmail uses https now, the exit node can only know you're acessing gmail, not the contents of that session.
keb
what if google runs exit enclaves
PeterT
ok thanks
rudi_s
PeterT: Just make sure you validate the SSL certificate of gmail.com, or the exit node could try a MITM-attack.
PeterT
how does one validate the certificate of google with ff?
rudi_s
PeterT: I think there is a plugin which helps you there, can't recall the name. But it should get validated automatically, just make sure you abort the connection if a firefox warning about unknown certificate pops up.
PeterT
What does the "services" tab do?
also, why does OFTC enable a cloak for us tor users?
dr|z3d
PeterT: That's oftc policy, which facilitates easier removal of problematic users from the network without impacting all Tor users.
keb
did the blog get slashdotted
BarkerJr
blog seems to be down
keb
how do i get a relay to serve the tor exit notice web page on port 80 but not allow directory fetches
BarkerJr
run apache :)
keb
maybe the dual-porpoise flags for DirPort could be unbundled
BarkerJr
dirport should be gone
SwissTorExit
i don't know why but Blutmagie4 look to sucks, it need mega lot of time to do a request and i am not sure that it will be able to handle :/
or maybe i am not lucky but i haven't this problem before
yeah, it goes on Blutmagie and it woked but slowly, just acceptable, anyway look to have some problem on his exit
Jadoza
(Action) is getting >600 kbyte/s over his bridge
That seems like quite a lot ... is there a lot of torrent leechers using tor bridges to remain anonymous?
atagar
Jadoza: the number of outbound connections should tell you if it's a single person using the bandwidth or several (it could be that your bridge is just especially popular)
(... and this sort of thing is why I'd like per-circuit bandwidth measurements...)
waggle
I've installed tor, torbutton and have replaced polipo's configuration with the one provided at torproject.org linux install instructions. I still get "Proxy Server Is Refusing Connections" immediately after I attempt to surf to any page. What could I be forgetting?
arma
atagar: want to work on a patch to the control protocol that tells the controller about them?
that seems quite useful at the client end. i'm not so excited about it at the relay side though.
waggle: is polipo actually running?
waggle
yes
Jadoza
atagar, It's like 9-16 for France, and 1-8 for Australia, Palestine, United Arab Emirates, Thailand, Iran, China, Pakistan, United States and Saudi Arabia
arma
jadoza: sounds like somebody is doing something big. that doesn't necessarily mean they're torrenting though. we've heard from some media websites that people will only publish video of local events to them if they're using tor.
Jadoza
since the last 60-ish hours
arma
waggle: did you restart polipo after changing the config?
atagar
arma: it's part of the not-exactly-popular circuit stats proposal (no sense in doing a patch if it wouldn't be accepted)
waggle
arma, yes
arma
atagar: right. i think it would be useful on the client end. on the relay end.... yeah, i can see both sides.

hello?
arma
waggle: your torbutton is trying to reach either localhost 8118 or 127.0.0.1 8118
sounds like they're not listening. i think that means your polipo is not configured right.
atagar
arma: I'll poke the proposal some more when I'm done with the arm rewrite and current set of feature requests (after that it might be fun to finally poke at the tor source to do some of the non-controversial parts)
waggle
arma, I'm quite confident I have the config listed on https://www.torproject.org/docs/tor-doc-unix.html.en#polipo
why does IRC work but not tor
arma
waggle: you are pointing your irc directly to tor (localhost 9050), whereas torbutton is trying to go through polipo. which is not listening on that port.
right click on 'tor enabled', go to preferences. do your proxy settings says "localhost" or "127.0.0.1"?
waggle
it says "use polipo"
arma
though i don't think having an ipv6 address for localhost is your problem. your problem is that polipo isn't listening at that port. what port *is* it listening on? 8123?
waggle
arma, how do I find that?
arma
telnet localhost 8123
waggle
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
what about ipv6
i dont have an ipv6 address
arma
::1 is an ipv6 address
waggle
my address is not ipv6
arma
in any case, it sounds like your polipo is listening on 8123. you did not change its config.
or if you did, you didn't restart it.
waggle
arma, I just checked it. It IS the correct file. the ports listed in there are 9050 and 8118. Although, every time I try to restart polipo, it says "its already running".
arma
ah ha. you're on ubuntu, right?
somebody was in here yesterday with this problem on ubuntu too.
waggle
yes
