ilter
Could someone say how much authorities are needed to setup private tor network? Afaik there're 7 authorities which are embedded in source codes. So on real tor network, at least 4 authorities say same to make a consensus document. What about for private tor netw? Is there minumun value for authorities? If we setup only one authority will it work?
Sebastian
ilter: not all features of Tor will work then
ilter: make three of them
then you can get most stuff to work.
ilter
Hello Sebastian. Nice to see you.
dun
atagar: as a newbieshly end-user I like your idea you just mentioned in #tor-dev
rudi_s
Sebastian: I'm curious. What needs more than one authority? The voting on the relays?
atagar: I like the idea as well.
ilter
Ok I'm trying with three. What about their config file? One of them is: http://pastebin.com/kDQ07qnD
Sebastian: Could you check it?
Sebastian
ilter: no TestingTorNetwork option?
or whatever that option is called
ilter
Hmm.. I though that this option is used only relays.
Ok i'm putting it.
Sebastian
you need to use it on every Tor node in your network
         

atagar
dun, rudi_s: Thanks! It was really pipe's idea - he was less-than-happy that finding a CLI controller was so hard. ;)
Sebastian
authority, relay, client
atagar: I think that's what the wiki is supposed to do.
that's less than ideal, though, I have to admit.
mostly because nobody looks at the wiki anyways
it's not really linked from the website
ilter
Sebastian: Is order of statements in torrc file important?
dun
its fine for experienced users, but the masses like screenshots, fancy guis etc :)
Sebastian
plus its a wiki, so it must suck ;)
ilter: sometimes it is, yes. For example, order of ExitPolicy lines
ilter: for most lines, it isn't.
ilter
For TestingTorNetwork line?
Sebastian
dun: I think arm & tork in general are niche tools
ilter: nope.
ilter
Ok thanks i've put it, now i'm trying it again.
Sebastian
I wonder if AssumeReachable needs to be set, too.
atagar
Sebastian: I'd be curious about how much their niche status is due to being obscure (I thought tork especially was quite a nice gem when I'd finally discovered it). But you're certainly right that if they aren't of much interest to end users then the site isn't an appropriate place for them.
Sebastian
atagar: Well, afaik TorK is pretty dead currently. Maybe I'm wrong here?
ilter
Should i remove files (cached-status etc.) which were existed by authority process was starting before?
atagar
not a clue (I was under the impression it's only used under KDE, yes?)
Sebastian
ilter: shouldn't matter, I think
atagar: the last release was in 2007
atagar
pity... improving its visability would definitley be a bad idea then...
ilter
Sebastian: First private authority gives this warn log when i started it; [warn] Received http status code 404 ("Not found") from server '127.0.0.1:6000' while fetching "/tor/keys/fp/701B4...". I couldn't understand why it receive 404. Could you say what is wrong?
Sebastian
hrm. I don't know either
ilter: ok, so how is this
I'll read backlog, make some food, and then set up a private network on my machine here.
ilter
It's good. Maybe you advise me also. Meanwhile what is backlog?
Sebastian
backlog is the stuff that was said when I was gone.
ilter
Sebastian: So now do you have time?
         

subbie3
is anyone else having problems with tor's hidden services
duckie
please be more specific
subbie3
when I was on a hidden service site I clicked a link to another part of the website, and it comes up with a blank white screen and says "done"
happend over and over
carnivore
A question: Can the ISP that sits in between a client and an entry node, see that one is connected to a Tor node?
dr|z3d
yes.
unless you happen to use a bridge.
then it's not so obvious.
subbie3
is it a big deal if it does, because when it starts to go though the nodes, everything becomes encrypted
Lonnie
Hey, I'm looking into using Tor, but I had a question...
dr|z3d
erm. no. the connection from your tor client to the first node is itself encrypted.
so the isp will be able to see that you're connected to the tor network, but not your traffic.
Lonnie
My ISP has gotten on to me about copyright infringement (torrenting) and I've been told Tor will stop my ISP from knowing it was specifically me. Is this true?
Sebastian
Lonnie: Tor isn't to hide your filesharing
ilter: patience. Will eat first.
Lonnie
It's not like I would be doing it 24/7
dr|z3d
Lonnie: You should have a look at http://i2p2.de
That's more suited to your purpose.
Lonnie
Just every now and then when I don't have money. I'm really impatient :/
How does I2P work?
dr|z3d
It's a bit like Tor's .onion stuff, except that's it's main purpose. it's a darknet.
Lonnie
What does that mean?
Sorry for being a complete noob =/
dr|z3d
It comes by default with an anonymous bittorrent client, amongst other stuff.
Lonnie
So I can download torrents and my ISP won't say
dr|z3d
It's an encrypted network you have to be on to access, essentially. Unless you use an external gateway, for some stuff.
Lonnie
"Hey, stop that.
"
GAH enter key is too big
dr|z3d
anonymous encrypted torrent downloads.
Lonnie
Oh, wow. Why did I know not of this before? xD
dr|z3d
Do please visit the site for more info.. we're all about Tor here, really.
Lonnie
Yeah, my bad.
ilter
Sebastian: Of course. Sorry for impatience.
Lonnie
I really appreciate the help.
People good at technology who aren't complete a-holes? :D
dr|z3d
You can come to #nottor for more info if you like.
Lonnie
Will do.
beggaboo
I'm loving the Tor-Android guy, so cute :)
Sebastian
ilter:
ok
So let's see if I can write a script
to set it up
ilter
Ok Sebastian. Thank you for your concern. I'll be here after some sleeping.
Sebastian
ilter: ok
I've got a bit of something working
ilter: ok, I'm running in some problems ;)
ilter: But the script works so far
http://paste.debian.net/65138/
neat
it seems that two v3 dirauths have massive bootstrapping issues
ilter: hah I found the problem I think
ilter: make the dirserver line this instead of what is in the pastebin
DIRSERVER_LINE="DirServer authority$NUM v3ident=$V3ID orport=$ORPORT \
no-v2 127.0.0.1:$DIRPORT $FP"$'\n'"$DIRSERVER_LINE";
note the added no-v2
narr
nice work
Sebastian
well, the tors still segfault
hm
I blame mikeperry
hrm
gdb isn't helpful
narr
you should go to bed
me too
guess ilter's not around any more anyway
Sebastian
pff
narr: hah
I think I got it
let's see if the Tors segfault again
narr
you're funny, do you know that? :)
in a way
Sebastian
hm?
hrm
yay
the segfaulted again
narr
:-/
Sebastian
FUCk this
ugh
anyone have an idea how to get a useful corefile?
let's see if debug logs are helpful in any way... -.-
mikeperry: around?
narr_
honest opinion: does tor need a new codebase?
Sebastian
a new codebase? No, why would it?
narr_
isn't it time to start from scratch and benefit from experience?
Sebastian
I still don't understand
narr_
i have the feeling that the codebase is somewhat messy
formalist
Sebastian. what's wrong? you're making me want to get in on ilter's experiment.
narr_
and that you guys have trouble integrating features, and finding people who want to work on it
formalist
now i all of the sudden want to try it.
Sebastian
formalist: trying to get this private network bootstrapped
authorities are segfaulting when they're making a consensus
formalist
:o
Sebastian
narr_: I don't think we have trouble integrating features
narr_: the codebase is complex, but not necessarily messy
narr_: also, shutting down for a year to rewrite Tor won't work that well, I guess
narr_
i think i'm not competent enough to discuss this more, before even having looked at the code
Sebastian
narr_: I quite agree.
narr_
but i thought i could also just ask
Sebastian
sure. I think the answer is a definite no :)
narr_
now that makes it certainly more interesting to think about working on it ;)
well it's probably just my aversion to C
hearing you fight against segfaults, with a more or less useless debug log
formalist
it might slow things down considerably but have you considered using strace?
Sebastian
well, i have no clue why the corefile is so useless
mikeperry
I didn't do it
what's going on?
Sebastian
mikeperry: my private Tor network's authorities are segfaulting when making a consensus
last debug level log msg is Mar 21 04:04:41.506 [info] networkstatus_compute_consensus(): Generating consensus using method 9.
formalist: yeah, not trying this on linux currently, so no strace
formalist: but I considered moving this experiment to a vm
formalist: I'd need to run it as root, of course, which might change something though.
formalist
(Action) nods :/
Sebastian
mikeperry: I'm mostly interested, did you ever get a private network set up that consists of only v3 authorities and made a method 9 consensus?
mikeperry
Sebastian: nope. didn't try it. too hard to create a network large enough to test the cases I wanted to test
is it segfaulting? or hitting a div by 0 or something?
Sebastian
It is segfaulting
the core is awesomely useless
let me pastebin
maybe you have advanced mad gdb skillz
http://paste.debian.net/65159/
any idea how to get a useful core?
haha, awesome debug logs
Mar 21 04:04:37.573 [debug] evdns_callback(): eventdns said that [scrubbed] resolves to [scrubbed]
mikeperry
you might have a ulimit on your core size
Sebastian
[shire privtor]$ ulimit -c
unlimited
mikeperry
do you have the debuginfo packages for libc and such? not sure how debian does that
Sebastian
that's os x
I've gotten useful cores before
-.-
the dumped files are also like 300mb
so... not really sure what's going on.
narr_
i'm off to bed, good night everyone
good luck hunting it down Sebastian
Sebastian
hrm, maybe I have more luck tomorrow. -.-
GadgetMan
anyone around that can help me setup Tor?
formalist
it doesn't like it when testtornetwork is set to 1.
testingtornetwork rather.
Sebastian
GadgetMan: ask a question
formalist: what does it say about testingtornetwork?
GadgetMan
I finally got firefox working with it but it takes like 2 minutes to get to a website
is that normal
Sebastian
no
GadgetMan
still hasn't gotten to the website
Sebastian
maybe you got really unlucky. Try hitting the "new identity" button in Vidalia.
GadgetMan
how do I setup it up in the main settings for mac
I tried but it didn't work
Sebastian
set up what
GadgetMan
probably don't need that actually, gonna try to set up Vuze
formalist
Sebastian. no. it's just that it doesn't segfault if TestingTorNetwork isn't set.
Sebastian
formalist: ah, so you reproduced the segfault
>
?
formalist
i did encounter one for each node.
Sebastian
when?
