Hi guys. Anymore ideas regarding this bandwidth issue? http://archives.seul.org/or/talk/Mar-2010/msg00088.html
Nothing changed in `cached-descriptors` and in `cached-consensus` Bandwidth is now 102, but looking at the transfer values nothing changed.
arma
anonymisierungsdien is the nickname?
several of the bandwidth authorities measure you at less than the 214KB/s that your relay estimated for itself
(that doesn't mean that you can't do 214KB/s. it means that you are not as good at doing 214KB/s as some other relays that advertise 214KB/s.)
the latest cached-consensus actually puts the consensus measurement at 90KB/s for that relay
http://trunk.torstatus.kgprog.com/router_detail.php?FP=b3ec1bf5d7f7d724ba634d91be5d22d2d7a70160 shows what it's been pushing lately
PaulePan1er
Sorry my system froze. Did anybody respond?
arma
PaulePan1er
arma: Thanks.
anonyisierungsdien is the nickname indeed. The IP is 62.141.42.186.
arma
what sort of bandwidth are you hoping it has?
PaulePan1er
arma: It is a rented server. So it should do the 5 MB/s without any problems.
Testing the bandwidth with for example wget showed no problems.
arma
it sure doesn't seem to be able to. anything in the logs?
         

PaulePan1er
arma: No, there is nothing in the logs.
arma
every so often we find people here who rented servers in germany that are 100MB/s guaranteed, and wget from some places on the internet show it, but tor doesn't make much use of them. i always wonder if the ISPs are somehow rate limiting when it comes to some locations, some protocols, etc.
nobody's really figured out what the story is.
ultramage
that's just sad
arma
well, it's not *just* sad. it's lots of other things too. :)
PaulePan1er
This morning I told Sebastian looking at `cached-descriptors` for routers with similar IP addresses revealed that CityTor seem to have the same problem.
router CityTor 62.141.37.243 9001 0 0, bandwidth 5242880 10485760 698982
But it does not seem to be running right now? At least I do not find it under http://trunk.torstatus.kgprog.com/ .
arma
correct, CityTor doesn't have any Running flags in its votes
PaulePan1er
Maybe I should check decreasing the advertised bandwidth will help.
bja
arma is it possible to wget using a finely crafted hidden service that is one hop away within the tor network?
PaulePan1er
But before I do that, does anyone know a test to see if the ISP is limiting the bandwidth.
?
arma
my guess is that decreasing the advertised bandwidth will just result in even less attention.
PaulePan1er
arma: Good to know. ;-)
I guess I will contact fast IT and ask them about this.
arma
try being a non-exit relay for a few days?
that would get you some more data at least
there is also a phenomenon in the tor network where, after a few days, we decide you're stable enough to be used as the first hop (i.e. you get the Guard flag)
then clients avoid you for hops other than the first hop (or the last, if you're an exit relay too),
but since clients pick guards and stick with them for a while, and not many clients have picked you yet since you just got the Guard flag,
there is an expected dip in traffic right after you get the guard flag
PaulePan1er
arma: I read about that phenomenon in the archive.
arma
if this is one of those cheapo vpn rental places, the support people you mail probably won't have any idea what's going on
PaulePan1er
arma: They seemed pretty knowledgeable last time I contacted them.
arma
great :)
PaulePan1er
arma: I guess I will wait until the support answers my request and then I will do as you suggested and configure the service as a Tor bridge as documented at <http://www.torproject.org/bridges.html.en#RunningABridge>.
arma
if you make it a bridge, it will get almost no attention
non-exit is not the same as bridge.
PaulePan1er
arma: Thanks for always correcting my false assumptions. ;-)
arma: So I just set `Exitpolicy reject *:*` for a non-exit relay?
arma
yes
i have another theory which is that clients are avoiding relays with both the Guard flag and the Exit flag, more than they should avoid them. mikeperry has some recent patches in 0.2.2.10-alpha to address that potential load balancing flaw.
so getting rid of your Exit flag for a little while will narrow down some possible reasons
         

PaulePan1er
arma
right.
PaulePan1er
arma: And looking at the email-address I know who is helping me out now! Thanks!
If I access torstatus.kgprog.com without trunk at the beginning the bandwidth images are not shown in the router details.
http://torstatus.kgprog.com/router_detail.php?FP=6297b13a687b521a59c6bd79188a2501ec03a065
Who is to be contacted about such issues?
arma: Since this might be a client problem upgrading Tor on my server to the experimental version will not help, will it?
arma
torstatus is the stable torstatus branch,
whereas trunk.torstatus is torstatus trunk
(development version, never actually released)
upgrading your server won't help, correct
PaulePan1er
arma: Still http://torstatus.kgprog.com/cgi-bin/perlgraph/plot.pl?plottype=rtw is notworking somehow.
arma
PaulePan1er
arma: That works. http://torstatus.blutmagie.de/router_detail.php?FP=6297b13a687b521a59c6bd79188a2501ec03a065
Does this work for you? <http://torstatus.kgprog.com/router_detail.php?FP=6297b13a687b521a59c6bd79188a2501ec03a065>
arma
the short answer is that the people who built torstatus don't maintain it much anymore. they answer mail if you send enough mails.
i try to limit the mails to "your database appears to be corrupt, can you fix"
PaulePan1er
arma: Sorry I did not understand your sentence. Are you writing it is a problem in TorStatus itself although it works for blutmagie?
<http://project.torstatus.kgprog.com/trac/ticket/128> might be related.
arma
looks plausible
i'm saying that nobody maintains torstatus much, or looks at those tickets much
(Action) runs across <a rel="nofollow" href="http://coldbot.com/price/tor,">http://coldbot.com/price/tor,</a> and wonders what they're actually selling
PaulePan1er
arma: I guess for people caring about privacy but not wanting/able to set up a server themselves can now be told, you can pay 90 pounds a month and you will improve the connectivity of the Tor network.
arma
pricy
PaulePan1er
arma: Indeed!
But it is not a bad idea. Does someone know those guys so they can be asked why they charge that much?
But having an option to just tell non-technical persons to donate a certain amount which will be used to operate a Tor server would be a nice idea.
arma
i don't know them. my guess is that 90 quid isn't very much if you live in london.
PaulePan1er
A suplemantal compaign for the 5000 relays campaign. »Sponsor a relay.«
You get a root server at Hetzner for 49 ¬/month with 2 TB traffic for 100 MBit/s connections inclusive which afterwards gets limited to 10 MBit/s.
http://www.hetzner.de/de/hosting/produktmatrix/rootserver-produktmatrix/#
Maybe a partner ISP can be found which special rates? Should I send a message to or-talk about this?
arma
part of the challenge is that we don't just want to get people to set up more and more relays at the same internet locations. the security of the tor network comes from diversity of operators, and diversity of network location.
so if somebody gave us $10000/mo for hosting a super fast tor relay, and we set one up that handles 50% of the tor network's traffic, we are hurting tor, not helping it, at least security-wise. performance-wise we are helping it.
PaulePan1er
arma: Understood. But I guess the project can react in such situations.
Sebastian_
arma: well, blutmagie is getting closer ;)
maybe we shouldn't fix all the relay perf bugs, else it'll be even stronger ;P
kmacy_
arma: do you lose security if you have independent operators at the same location?
PaulePan1er
Does anyone know why blutmagie was down for a couple of weeks in the end of January to the begin of February?
Sebastian_
kmacy_: yes, because that location can log
PaulePan1er: I don't off the top of my head, but you might want to check for mail from Olaf to or-talk
PaulePan1er
Sebastian_: I will tomorrow.
arma
kmacy_: against some attacks yes, and against some no.
PaulePan1er
Good night everyone.

StrangeCharm
how can i ssh via tor under ubuntu?
arma
torify ssh ...
or the newer, "usewithtor ssh ..."
in both of those cases, you'll be happier using an ip address as your ssh destination.
if you must use something that you need to resolve, then socat is your answer. see the torify howto on the wiki.

arma, StrangeCharm: connect.c or the newer corkscrew are ssh proxies, you can use them to use ssh through any http proxy
arma
corkscrew?
sid77
corkscrew :)
let me fetch the link I packaged it on slackbuilds.org
arma
(Action) finds <a rel="nofollow" href="http://en.wikipedia.org/wiki/Corkscrew_(program)">http://en.wikipedia.org/wiki/Corkscrew_(program)</a>
sid77
http://www.agroman.net/corkscrew/
arma
yep
sid77
ouch too late
I usually use ProxyCommand /usr/bin/corkscrew proxy.example.com 8080 %h %p
in my ssh config
(ProxyCommand /usr/bin/corkscrew 127.0.0.1 8118 %h %p for usage with Tor)
arma
and it uses the http CONNECT command?
StrangeCharm
sid77, sorry, i'm not totally clear on how to use corkscrew
arma
it mentioned handling http proxies too (in addition to https proxies). that would be a good trick.
StrangeCharm
when i corkscrew 127.0.0.1 8118 %h %p, i get SSH-2.0-OpenSSH_5.1p1 Debian-6ubuntu2, and anything i type after that gives me 'protocol mismatch'
arma
strangecharm: you put that as your proxycommand in your ssh config?
sid77
StrangeCharm: you have to use the string I wrote here in your ~/.ssh/config
StrangeCharm
no, i don't want to use corkscrew/tor generally, just on this one occasion
sid77, it's not possible to call corkscrew directly?
sid77
create a config stanza for the hosts you want to connect to using corckscrew
don't think so
arma
for the one occasion, i would a) tor-resolve destination.com. b) torify ssh ip-address
StrangeCharm
arma are torify and tor-resolve programs?
i don't seem to be able to apt-get them from the tor debian/ubuntu repo
arma
they're in the tor deb
StrangeCharm
oh, they're already installed, i see
arma
torify is a wrapper around tsocks
sid77
ssh config is really powerful, you can create a "a_mnemonic_name_you_like" section, write in it server ip address and all the configurations youìd like to apply to just that host and theen you only have to issue "ssh a_mnemonic_name_you_like" to connect to the specified ip with all the configurations applied to that host only
StrangeCharm
i am not yet ready for this dark magic
sid77
:)
StrangeCharm
well, that works
i guess i'll have to investigate this dark magic to make this easier in future
gosh darn it, there are so many ways to leak your identity
conducting any sort of business anonymously is a total hassle
arma
strangecharm: indeed. and then prepare yourself for your bank to close your account because you logged in from turkey and clearly it's compromised
StrangeCharm
arma, oh, not business in a financial sense. more like run this program on this server.
sid77
oh, can anyone following tor-java tell me one of the latest topic? I'm switching between mail addresses and mail alias and looks like I'm not subscribed to this list even if I was thinking too
(no, looking up on the web ail archive doesn't work: it's broken :-P )
*mail
ok I was subscribed with the right address, never mind sorry for the noise
arma
it's broken? woah, it is broken.
there, fixed.
why does nobody tell me these things. :)
sid77
arma: thanks!

hi
i need password
Runa
for?
PaulGhost
for Tor
So what's now?
Runa
I'm not sure what you think you need a password for
PaulGhost
Where i can have it?
i must give for Tor
give password for Tor*
Runa
where do you need to give Tor a password?
what are you trying to do?
PaulGhost
i can start it
i must give password.. :(
can't, sorry
Runa
which os?
