I'm running this on 4 machines. I did a little comparison of what routes my 4 PCs discover or trace and honestly, they've got nothing in common. One somehow alway ends up in China while another one seems to be fixed on the US, the third one stays in Europe and my fourth PC just now showed me a route to New Zealand.

In that respect, I think that more machines are actually better, but that's just a feeling based on my observations.

I remember reading something abou that on the DIMES forums. IIRC, they said something about 1kb per client per minute(?) adding up to about 30 MB a month.

Just look it up on the DIMES forums.

I looked it up on the Dimes forum, but the thread died in August with not real word on what was going to happen. Some were claiming higher numbers it seemed, but the project leaders never responded about what they really thought was going on(?).

My concern was sending up to 10 or so machines through a single proxy server, and how much that would effect it. Guess there is only one way to figure it out.

Thanks for the responses.

Yeah, I have also compared my two crunchers. But this is not only a question of the tracing, but of stats: if you from one point try to trace lets say 100 000 other computers, then the traces closest to you will be well mapped (lets say the 5 - 15 first nodes). all that is further away will be more dependent on the local traffic on those nodes, and that is better mapped by the comps closer to those nodes.
That is probably the reason why the project wants comps in many diffrent locations. I have asked a friend 250 km away from me to run Dimes - and he gets totally differnt traces. Why? because a very big trunk cable is closer to his location and an other very big trunk cable is closer to my location. A third friend - only 90 km away but across the Baltic sea in Finland gets totally different traces ...

I have saved and printed on plastic OH sheets 10 different screens and put them on top of each other, and now I know all the ways out of my town to the net: it is - as a matter of fact - no more than 12 different ways a signal can get out of my region (that is around 90 - 220 km around my location). The fun part is: which route is used when and why. I think this is the question the scientists of Dimes want to answer, because I think that the signalling is dependent on load, errors, problems, poweroutages, and other thinks that affect the pathways.

This may be very different in an area which is more densly populated, such as central Europe or the coasts in the USA. Here we have a very low population density, and although (almost) every home has broadband (10mbit/s or more) there are only 125 000 homes in an area of 250 x 450 km. The companies do not count, it is less than 10 000. We are also sitting across one of the bigger trunk cables (the biggest in Sweden) going from our university south to Stockholm and further on to the rest of Europe an to the USA. So there is not very much to map, I think ....

I have decided not to put more comps on this project. Not only because of my reasoning above, but also because most of my comps are "old" and by far not as powerful as P4s and athlon 64s and such... You know: many small ditches empty the big lake ...

 
My firewall (Sygate Personal Firewall) sometimes asks if I want to allow "NT OS Kernel" to send a ping/packet since I installed DIMES. And also since I installed DIMES, I regularly tells me that I'm under a "smurf" attack, with somebody spoofing my system. But I guess that has to do with DIMES as well and the attacks are fended off anyway by the firewall, altought I'm sure these aren't reall attacks, but mere "answers" to the tracerouts/pings of DIMES.

I have had no problems with Outpost, Zonealarm pro and my hardware firewall. As mrwizer said: just let javaw.exe to send out IP-protocolls (UDP and ICMP) at the same ports as the browsers.
Others have had minor problems with Zonealarm (the free version). These problems were solved when the security level were set to "medium". I have no experience with other firewalls, but have not read about any problems in the forums.
 
I have ZoneAlarm free on one of my machines, and no issues here. But I have had issues with ZA on other apps... sometimes it seems that even when you give permission to an app, it does not allow it.

If you have issues, you can set the program control to "learning mode". This has solved most of my issues with apps that cannot connect.
 
I use Kerio Personal Firewall 4 (the free version) and DIMES is working fine, I just had to allow it to access the internet the first time it tried to.
 
Well shoot I'd forgotten this doesn't take any real CPU power! 😱

I'm in once I've figured it & have time ,probably tomorrow evening🙂

btw dringdahl ,if you mentioned in the topic summary that dimes doesn't take away CPU power from other DC projects (that's right isn't it?) then I'm sure you'd get a load more people🙂

[edit] is there anything special I need to do to join TA (I assume theirs teams in it?)

damn I get a 'javaw.exe not accessable ' error on my win2k rig 🙁
I gotta sleep now ,I'll check back tomorrow for answers😉

[edit]forgot to say ,totally agree with amdxborg 1st post.
People thinking of themselves & not the team!
 
Hi Mark, thanx for joning!! 😀

You've gotto make sure you've got the latest java installed on you're pc www.java.com

When you install the client, there's a option to join a group and that would be Anandtech 😉
 
Isn't it necessary to let your firewall allow incoming and outgoing ICMP for the project to work properly? I had told my firewall not to allow it this morning and when I got home there were 500 hits on each computer.

yeah, i didn't realize that.

how is AT not in the top 5 PPD? lets get this rolling. i think i see 5 new users added ~20k/day.

Well, you can set Dimes to work with ICMP and with UDP. You can aso set it to work with UDP alone (or ICMP alone). Just push the "All Protocolls" button up left in the "Graphs tab" and you can choose. You can alsop choose between just using "ping" or "traceroute" or both (=all operations) or you can write your own scripts - but how that is done I do not know.

I find this client very flexible - but as mrwizer said - I do not know what the "points" in the stats are. Well: AS means autonomous cluster" but what exactly yhat is I have not understood yet... 🙂
 
Yes it worked, and that version of zonealarm works very well, I don't need all the bells and whistles of the much larger and newer version of ZA.
 
I'll try to help but I need a little help.

I've posted on Johan's off-site TA Forum but there is not much discussion there about DIMES.

Who is the Founder?

Can we get our team named changed to "TeAm AnandTech" so it conforms to the name of our other teams?

Can you switch teams? How?

I'm holding off my registration until I learn a little more. I typed in "TeAm AnandTech" for the team but got back an error message that the team didn't exist and asked if I wanted to create one.

We definitely don't want to have multiple "TeAm AnandTech" teams floating around. 😉

Thanks for the link, Jim.

So I see that Woodie is the owner(founder), I've just sent him a PM.

Though not necessary, it would be consistent with most of our other teams if the name were, "TeAm AnandTech". Hope Woodie can and is agreeable to changing it. 🙂
