Relay bandwidth needed to pay back Hidden Service usage
Say a hidden service makes available a 100,000 byte file. Now another user downloads that file. There was obviously some 'cost' in bytes to the six hop relay system for doing that. Say the user who downloaded that file feels obligated to repay his usage back to the system by running his own non-exit relay. How many bytes should he offer back to the network? It may be more proper to think of it as bandwith. Server serves a stream 24x7x365 at 100,000bps. User consumes it 24x7x365. How much inbound and outbound pipe should user provision to replace his usage? When compared to the internet, the network is a closed system with finite resources, so the cost is certainly not equal to his usage [ie: 1x]. His usage causes a depression of overall available resources during the transfer. I thought it might simply be 6x his usage due to 6 hops. But maybe it involves adding 6 increasing fractions? And what about the middle relays that both receive and send the supply stream? Tor overhead and packet retransmissions can be ignored. Tor's configuration limits and the availablity of any given pipe size can also be ignored as this is only an excercise. The return tcp ack stream would not be negligible but could be left out by reference... only if it was simply additive on top of the supply stream using the same calculations. *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/

Yes I could have some informations like these indirectly using grep on log files but I liked to have something also from tor server. -- Ciao leandro pgpfHczfb5de5.pgp Description: PGP signature
Hidden service usage
Ciao a tutti, I would like to control the usage (the amount of connections or something like) to a hidden service I have. In the man page (0.2.2.1-alpha-1 version) I found these directives: AuthoritativeDirectory 0|1 When this option is set to 1, Tor operates as an authoritative directory server. Instead of caching the directory, it generates its own list of good servers, signs it, and sends that to the clients. Unless the clients already have you listed as a trusted directory, you probably do not want to set this option. Please coordinate with the other admins at tor-...@freehaven.net if you think you should be a directory. HSAuthoritativeDir 0|1 Whenthis option isset inaddition to AuthoritativeDirectory, Tor also accepts and serves hidden service descriptors. (Default: 0) HSAuthorityRecordStats 0|1 Whenthis option isset inaddition to HSAuthoritativeDir, Tor periodically (every 15 minutes) writes statistics about hidden service usage to a file hsusage in its data directory. (Default: 0) DataDirectory/hsusage Used to track hidden service usage in terms of fetch and publish requests to this hidden service authoritative directory. Only used when recording of statistics is enabled. As I can understand I need to enable all to have something, right? The first option is not only for directory servers? And also, what kind of information I will have? -- Ciao leandro pgpq8hkkZOngv.pgp Description: PGP signature

Unless the tor developers have arranged with you for you to operate a directory authority of some kind, you will not use any of the above options. Other people would only have need to set those options in a laboratory situation in which they were setting up their own internal tor network. Do NOT play with those options on tor relays running in the real-world tor network. And also, what kind of information I will have? Please be more explicit about what you wish to do.
