Farb Posted May 19, 2017 Author Share Posted May 19, 2017 It seems I had a network misconfiguration that was not allowing peers to connect. I think it's fixed now so we'll see if things start working for folks. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted May 19, 2017 Share Posted May 19, 2017 (edited) okay... what's the IP I perma banned people who sat a zero for more that 48 hours still got nothing coming I will manually add the peer ip and port I leach at 330MiB down and feed at 25 MiB up Edited May 19, 2017 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...
AtariGeezer Posted May 19, 2017 Share Posted May 19, 2017 Looks okay to me, there are files that are bigger than 3 MB and conversational German at 271 MB which leaves 184 MB for all the rest which are less than 1 MB and most of those are less than 100k...

_The Doctor__ Posted May 19, 2017 Share Posted May 19, 2017 cool, the numbers are good but the torrent is still stalled correct? Quote Link to comment Share on other sites More sharing options...
Farb Posted May 19, 2017 Author Share Posted May 19, 2017 Ok, I was trying to be clever and set up a torrent server so there was always a seed. That seems to have failed miserably, so here's a torrent file created the same way I've done the previous ones...

AtariGeezer Posted May 19, 2017 Share Posted May 19, 2017 (edited) Yep, no peers are currently downloading ... New torrent downloaded 100% and now seeding... Edited May 19, 2017 by AtariGeezer 1 Quote Link to comment Share on other sites More sharing options...
Clay Cowgill Posted May 19, 2017 Share Posted May 19, 2017 I'm at 100% now, I cranked up my upstream limit and will leave it seeding for overnight and some time tomorrow. Thanks for all the work on thie Farb! 1 Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted May 19, 2017 Share Posted May 19, 2017 (edited) it is rolling along but rather slowly.... only 300 KiB/s I sure hope everyone delete all parts and files of the failed torrents as the name and folders may resend whatever was part of the old torrent 2 seeds found I am currently uploading 3x more than I am getting...

Clay Cowgill Posted May 19, 2017 Share Posted May 19, 2017 I turned my upstream throttling off entirely, but it's not going above ~500kB/s. Probably Comcast choking off torrent traffic or something... 2 Quote Link to comment Share on other sites More sharing options...

ijor Posted May 21, 2017 Share Posted May 21, 2017 Here is a clean working dump of Zeppelin. As the name of the file implies, this title works only on an 810 drive. It will randomly fail on a 1050 and probably on everything else as well. So if using Altirra, make sure the drive is configured as 810. Will elaborate later ... I wanted to make a detailed article about this because it is quite interesting. But never found the time. So I am posting here the main concept "as headlines" without much of a redaction. Technically oriented people will probably understand, I hope - Zeppelin uses the so called skew align as one of its protections. - Skew align refers to a specific angular alignment of the sectors across different tracks. - Most titles with this protection were formatted aligned with the index hole. - So that the same physical sector number is located at almost the same angular position in all the tracks. - The typical protection check performs something like reading physical sector one of a track, then sector one of an adjacent track, and measures the total time taken. It should be one full revolution. - Some protections measure the actual RPM before, others assume a nominal value. - The specific drive and firmware timings, such as seek time and settle delay, are not relevant. It always takes one full revolution because the revolution time is much bigger. - The total time since the drive starts reading the first sector until being ready to read the other one in the adjacent track is in the order of 150 ms; while a full revolution takes 208 ms. - So the drive always needs to wait one full revolution disregarding if it was ready 20 ms earlier or later. - Zeppelin disks are is not aligned to the index hole. The skew align was achieved likely using timing. - That means that sectors with the same physical number in different tracks are not at the same angular position. - It also makes the formatted alignment not that accurate because it is more influenced by the drive RPM. - The angular distance between specific sectors on adjacent tracks is not constant. This is probably on purpose to make reproduction of the alignment more difficult. - But note that yet the alignment across multiple copies is, of course, (more or less) constant for a given pair of tracks. - Protection is checked similarly as the typical case, measuring the elapsed time since reading physical sector one of a random track, until reading also physical sector one on an adjacent track. - But because of the not constant alignment, it doesn’t always take one revolution. The software has a table for the expected time for each track. - And because now in some tracks it takes less time than one revolution, the internal drive timings become relevant and significant. - The protection assumes the timing matches a standard 810 drive. Just about any other drive would randomly fail the protection. 6 Quote Link to comment Share on other sites More sharing options...
Farb Posted May 22, 2017 Author Share Posted May 22, 2017 This is fantastic information - thanks, Ijor. I've updated the information for the Zeppelin dump on the preservation website with this info. Quote Link to comment Share on other sites More sharing options...
+DjayBee Posted May 22, 2017 Share Posted May 22, 2017 - But because of the not constant alignment, it doesn’t always take one revolution. The software has a table for the expected time for each track. Slight correction: It's actually two tables to diffenrentiate between PAL and NTSC. 1 Quote Link to comment Share on other sites More sharing options...
