usb audio problem
I use HRT music streamer, which uses uaudio driver. But in mplayer when I play a movie, it sounds normal for some time and then suddenly plays no sound at all. it is not muted and mplayer recognizes that it works correctly. Only after reboot ,it sounds again, but as above it dies after some time when playing movie. In linux there was no problem, so it cannot be the problem of HRT music streamer. any ideas? -- *Kim* ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

An informed critic would have recognized that the 'lack of knowledge' issue, and the 'nonsense questions' were two -entirely- different matters. grin One who lacks knowledge of system fundamentals and asks questions _about_ _the_fundammentals_ that they do not understand is not subject to criticizm -- they are educatable. Those who make grossly false-to-fact assumptions about the behavior of those fundamentals, and extrapolate wildly from those erroneous assumptions cannot be engaged in rational conversation -without- hauling them back to the initial erroneous assumptions, and correcting those errors. And, when that is done, it invaliates everything extrapolated from the false premise. Those who continue to extrapolate wildly in such manner cannot be helped. It was also established that the OP's descriptions were woefully incomplete and unreliable. A second disk was involved. 'dangerously dedicated' or otherwise? partitioning? slices? label type? There is indirect indication 'everything of interest' was on a single slice, but that is only an inference. There's no indication of where _in_the_filesystem_ on the slice that the jails '/' directories were located, or by what names they were known to the system outside the jail. The 'pattern' of the names, and placement in the hierarchy _is_ likely of some significance. As is (a) ownership, (b) permissions, and (c) 'flags', of (1) the original 'containing' directory, (b) the external view of the jail '/' directories in that directory, and (c) 'where they ended up'. It is likely that that 'external view' (pre- problem) of the jail '/'s does not exist -- unless one had historical data from before the problem. Everything was running in jails. Except for things that weren't. For any constructive analysis of what happened, one needed to capture *all* the bits in the directory (itself) where the jails ended up -- a directory 'listing', e.g. 'ls' (regardless of options), is not sufficient -- and the same for the directory where they 'should have been', plus a copy of the slice's complete inode table -- i.e., from _all_ the cylinder groups. Then one would examine the 'last modified' timestamp on the directory where the jails were found, and -then- the timestamps on the jail directories themselves. Among other things, this data allows one to establish whether or not the jail directories were ever _really_ where one thought they were, or whether they just 'appeared' to be there, e.g. due to nullfs, or a 'link'. And an 'initial estimate' of -when- it may have happened. (if 'malice' is involved, or certain kinds of backup/restore activities, the timestamps _may_ not be accurate, but they are a 'best available' guess.) Capturing -all- the data from the 'where they were' directory, allows one to examine the 'deleted' entries -- where one _should_ find entries for the jails, and 'last accessed' timestamps which put a lower bound on when the 'move' occured. When the 'apparently impossible' happens, it is *VERY*OFTEN* the case that 'reality' is *NOT* what someone 'knows' it is. No matter how 'obvious' it is, one has to =verify=. It is also _FAR_ 'easier to believe' that (especially) a nullfs mount (or, less likely, a hard link) disappeared, than directories actually got moved. The move may well have happened, but one must 'positively' eliminate the 'more plausible' alternatives first. Things that would 'give the appearance' of what was reported, but from -very- different causations. Of course, to capture this kind of information, one have to know what's where in the filesystem metadata, and have means to capture it _without_ changing any of that data. And _that_ means that you have to have a fair understanding of the mechanics of how the filesystem works. Which rapidly leads into gory details of how the O/S does disk I/O, and the various performance optimizations (and trade-offs) employed.

Has anybody out there taken the BSDA certification exams?
Hi List, on Saturday the 5th of May there is the Central-European BSD day in Vienna. They also give the chance to make the BSDA certification exams. I went through the 'BSD Associate Exam Objectives' to get some idea the questions. But I still wonder, how NetBSD users get away with the style of questions and solutions asked. Its some years ago that I used FreeBSD and I have for sure forgotten lots of details or never ran into certain commands/solutions since changing to NetBSD. Has any of you taken the exams? Has somebody told you about the exams? By the Exam Objectives I think its not that easy to pass ...

So, what is the variable 'port' initialized to? It should be a const
char* with the name of a network service found in /etc/services or else
the string representation of a port number in decimal.
Failing that, this is almost certainly a configuration snafu on your
9.0-STABLE box.
Does this machine have an entry for localhost in /etc/hosts ? Can it
resolve localhost via the DNS? Or through any other means such as NIS or
LDAP?
What does:
% getent hosts localhost
return?
If that fails, sanity check /etc/nsswitch.conf and /etc/resolv.conf
Cheers,
Matthew

netif starting late after upgrade to FreeBSD 9.0 from 8
I've just upgraded in place from FreeBSD 8 to FreeBSD 9.0. The upgrade following /usr/src/UPDATING was without any problems.

In fact, O'Reilly has a 50% off deal for a few ebooks about C programming right now: http://shop.oreilly.com/category/deals/c-programming.do O'Reilly's ebook deals are about the only way I've found to get good technical books from a major publisher in digital formats at a reasonable price, considering most of the publishing world still thinks it's okay to charge more for ebooks than for hardcopy books for some asinine reason. O'Reilly is, in fact, pretty far ahead of competitors on its handling of ebooks. For instance, if you have a hardcopy O'Reilly book, you can register it by ISBN with O'Reilly, then get an ebook copy of it for about five bucks. By contrast, The Pragmatic Bookshelf (which produces very high quality books as well) at *best* gives you the opportunity to get a hardcopy book plus a PDF book at the same time for about 150% of the cover price of the hardcopy alone, *only* if you buy them together from the Pragmatic website itself, and if you only have the ebook or the hardcopy book you have no way to get a discount on the other; you have to pay full price. Pragmatic does offer ebooks at slightly lower price than hardcopy, which is at least better than the standard industry practice for science fiction, but it's a ridiculous price for a bundle of bits in a digital file. O'Reilly offers some kind of discount on hardcopies for people who have the ebooks, too, I think. I'm not sure -- I've never taken advantage of that discount, because I only started collecting ebook copies of O'Reilly books after getting an e-ink reader, which I find every bit as good for many (though not all) reading purposes as a physical dead tree format book.
