Thus spake Shawn K. Quinn ([EMAIL PROTECTED]) [06/09/05 09:22]: : 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. : : The bigger problem is convincing the library's computer to run your : software without getting caught. Even then, there's no guarantee that : the computers have direct Internet access; it's likely everything is : funneled through proxies. Generally speaking, it's not terribly difficult to convince a library computer to run your software. Especially if there's anything from MS Office installed. And whether or not it's funneled through proxies doesn't matter one bit: you're submitted a valid HTTP request to a valid HTTP port. There's no reason the proxy would reject your request. At this point, I think I'll put my money where my mouth is, and try running a TOR node (client only) at my local library. See what happens.

Thus spake Tyler Durden ([EMAIL PROTECTED]) [03/09/05 14:03]: : Well, here I meant after registration, etc...in a regular IP network it : can take seconds to minutes in order for routing tables (at layer 3) or the : local MAC Address tables (at layer 2) to recognize that you're back on : line. With a Tor node I'm wondering how long it takes for the greater Tor : network to both notice your existence and then trust that you're here to : stay...for a while. : : In other words, am I contributing to the greater Tor network if I allow my : USB Tor node to function while I'm sucking down a cappucino or two? 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

They might as well just block TCP/IP. Do they do this by blocking the likely ports or by merely de-balling the protocol stack somehow? I assume Tor is smart enough to try various open ports -TD

Not that middleman is not useful, mind you (this applies to both Tor and Mixmaster). -- Shawn K. Quinn [EMAIL PROTECTED]

I assume Tor is smart enough to try various open ports All you get access to as a library card holder is a Web browser (or pathetic excuse for same, as I think it's a hacked-up IE). 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. Now, the Harris County libraries might be different; I have not gone to one. -- Shawn K. Quinn [EMAIL PROTECTED]
