As others have stated, no, likely not: bouncing your connection up and down like that will likely cause great untrust within the TOR routing. Whether you will be /harming/ the TOR network or not is a more interesting question... I'd suspect not, but it's probably worth looking into. : In other words, just for me. That, of course, is great. Good. : As for simplicity, I need that: I know my way around the BLSR protection : switching bytes in an OC-48 4 fiber ring, but I'm a veritable IP dummy (oh, : well I DID design parts of a layer 2 GbE switch, but I'm no routing jock). : I just don't have time to have to fiddle with the OS myself, so this will : be interesting. Think I might get me one of those gizmos and then stick it : on my PDA. It is, quite literally, a matter of installing the binary (whichever OS you are using will determine the method of installation), setting two, maybe three configuration parameters -- things like logging levels, interfaces to use, and other very basic parameters -- starting it up and using it. So I imagine you can handle it quite easily. : So: Can Tor support VoIP Yet? I could call up bin Laden from a Starbucks! In theory, TOR can support anything that can handle a SOCKS connection. So if your VoIP program can do SOCKS, then yes, it can. If your VoIP program can't, wrappers are readily available. The question to ask here is: can TOR support VoIP /well/? I wouldn't put much faith in maintaining a solid VoIP connection: due to the very nature of what TOR does, you're introducing a substantial amount of latency to your connection, and it might be enough to throw off any VoIP connections you try to make. But it's worth trying... - Damian

Thus spake Tyler Durden ([EMAIL PROTECTED]) [04/09/05 21:14]: : I assume Tor is smart enough to try various open ports TOR can only contact other entry/mid/exit nodes on the ports they're listening on. The documentation actually requests that people set up nodes on TCP ports 80 and 443, for the exact case that this Houston, TX library seems to be in. So yes, TOR *is* smart enough to try various open ports, but it will only work if something is listening on said ports.

The computers at the Houston libraries don't allow access to the USB ports from what I have seen, and in order to get access to anything besides a Web browser you would probably need to reboot the machine and you then have maybe 15-20 minutes before a librarian notices you.

A few days after you register. : In other words, if I go into a Starbucks with this thing, can my laptop or : whatever start acting like a temporary Tor node? Yep. But I'm not sure you'd want to do that... AFAIK, TOR can handle dynamic addresses. So long as you've got a public address, you can act as a TOR entry/exit point. So you could, in theory, set up a TOR entry/exit point on your local Starbuck's network. All you'd have to do is register, and jump a few hoops to register your dynamic address. I don't know if the same holds true if it's not a public address. Though, you can just skip all that, walk in to Starbucks, sit down, and start using your TOR node as your own entry point. No registration, no wait, no nothing: just sit down and go. I just set a node up a few days ago, and was surprised at how simple it was to get TOR up and going.
Re: Perhaps the real reason why Chavez is being targeted?
While the US certainly has been interfering with Chavez and generally trying to mess around in Venezuela for a while, most of what's happening here is just that Chavez is running off at the mouth for domestic political reasons. (Pat Robertson was partly doing that also and partly just babbling.) The leftist Z-mag had an interesting article about Chavez last month. Although most of Z-mag's articles are fairly silly leftwing ranting, you defiintely have a few in-the-trenches-type articles that show up every now and then. The article on Chavez is most interesting and strongly suggests that what Chavez is actually doing is trying to drive up the price Venezuela gets per barrel. Apparently, he's been successful, and most major oil companies (with the notable exception of Exxon) have recently signed very favorable contracts with his government. Also of interest is the proliferation of Chinese and other oil companies edging in next to the big US UK oil firms that have traditionally dominated such deals. The business about shipping oil to Jamaica is interesting; he'd previously been talking about selling cheap gasoline to poor US communities, which was high-grade political bullshit that he had no mechanism for implementing, and quite amusing. Maybe not quite bullshit after all...the major barrier to doing this (ie, shipping low cost oil to some contries and communities) was that the oil was in a form that required processing before it could be used (when I get home I'll try to look up the specifics). Only a few companies could do this and he now has such companies signed (one is Chinese, I think). But fundamentally the US government's problem is that he's a leftist who hangs out with Castro and has oil and likes to do land reform and nationalize oil companies, which is not the kind of thing that right-wing industrialists like. Well, that's always the catch. Mao and (to a much lesser extent) Castro were effective guerilla warriors, but Mao had to die of old age in order for China to start developing itself (Cuba speaks for itself). Chavez seems to be spending a lot of the oil wealth on lots of social services which, though perhaps noble, is not sustainable. If Chavez were bright enough to use this $$$ to kick-start a modern economy his rhetoric would then prove to be much more than hot air. In short, I'm not convinced Chavez is an idiot. From this vantage point I'd argue it's way too early to tell. -TD
