Re: [gentoo-user] new machine : DVD drive
(1) do I need to configure the kernel to find the drive ? It's basically handled exactly the same as a CD drive, so you need the same configuration options you would use for that. Yes. As a minimum have a look at BLK_DEV_SR and BLK_DEV_SR_VENDOR. You may also need SCSI_PROC_FS for legacy applications. The AHCI drivers would probably be enabled for your hard drive SATA controller anyway. BLK_DEV_SR_VENDOR made sense when every drive manufacturer adopted their own standard in designing interface protocols... with every drive made on the planet in the last ten years being mmc-compliant, there is not much point in still using that. Not that it hurts even if it's not needed... (3) are there rewritable DVDs, as there used to be rewritable CDs ? -- among the specs are much slower speeds labelled 'RW'. Yes, +RW, -RW, but don't know much more on this other than older DVD writers would only do one format not another and if you didn't pay attention to the specification/limitations of your hardware you could end up buying the wrong type of DVDs. Someone more experienced on recording media could answer this better. Every modern recorder does both standards; depending on both the burner and the reader you might find that one standard works better than the other (i.e. has lower read error rates). Trial and error seems to be the only working approach... As for the standards, if you're just burning backups they're basically equivalent. The +RW standard is theoretically more flexible as media can be formatted in a packet mode which allows (almost) random r/w access, but in my experience software support and reliability have always been lousy, so forget about it. +RW media cannot be erased in the same way CD-RWs are erased, -- you can only overwrite it with new data. -RW behaves the same as CD-RWs in this regard. If you need rewritable DVD media with reliable random r/w access (but this doesn't seem to be your case), there is a third standard (DVD-RAM) which uses special disks with hardware sector marks. Drive support is not hard to find nowadays (the drive you cited actually supports it), but writing is slow, good media is expensive and the disks cannot be read in most normal dvd drives; I have no idea about the state of software support in Linux. (4) anything else I sb aware of ? DVDs (especially rewritable ones) are much less resilient than CDs. Don't rely on a recorded DVD to be still readable after more than 3-4 years, because it probably won't be. While good quality (i.e. expensive) brand media tends to be a little more durable, DVDs are not the right choice for long-term archival. Given your adoption rate of new technology I suggest you consider buying a BluRay player if not recorder, because I don't know how long it will be before DVDs become obsolete too. I doubt BD-R will ever supplant DVD-R the same way DVD-R did with CD-R. When DVD-R came out there were no practical and affordable alternatives for recording and transporting large quantities of data. Nowadays, on the other hand, flash storage is ubiquitous and cheap enough to satisfy the needs of most people. This slowed the adoption of BD-R a lot, to the point that I'm not sure it will ever become a widespread technology.

Someone more experienced on recording media could answer this better. Almost all of this stuff settled a little under a decade ago, but in the beginning there was just the DVD. The DVD had a field in its metadata called book type, which was supposed to tell the DVD player what kind of DVD it was. Was it a manufacturer-pressed disc? Was it a burned disc? Was it something else? In order to master DVDs, you had to get specially-licensed and controlled master discs, drives and software which would allow you to write to that book type field. DVD-R came out, and pressures from Hollywood dictated that this DVD-R format hardcode a value into that Book Type field that declared the disc as a burnable disc. This way, people who tried copying or burning movies and the like would have these discs rejected by DVD players. Some DVD players wouldn't play back movies from DVD-R discs. Some DVD players wouldn't even acknowledge them; as far as these players were concerned, that particular value in the 'book type' field was still 'reserved', so any disc that used it was invalid. Along comes the DVD+R format. The DVD+R format has some variances in *how* data is represented on disc, but to the player that doesn't know any better, it looks just like any other DVD. The big difference DVD+R brought was that the 'book type' field was burnable on any drive which was capable of burning DVD+R media, and a disc appropriately burned would play in any home DVD player as though it were a pressed disc. (Yay, we can has home-recorded movies again!) Both DVD+R and DVD-R discs are sold, but I only ever buy DVD+R discs; as far as I can tell, playback works in everything, and just about any recorder will record to them. I have to think that the DVD-R discs are sold only because there are still some ancient burners out there. When in doubt, go with DVD+R. (4) anything else I sb aware of ?

Unfortunately BluRay devices were out of my price range last time I bought hardware to justify paying the extra, so I can't recommend any. There's something to this; a single-layer DVD only holds 4.7GB of data. I carry around more rewriteable storage capacity than that in my pants. (Literally; I have a pelican case full of SD and micro-SD cards, for photography purposes.) If this is a backup solution, it's probably better to look at blu-ray or (even better) modern tape drive solutions. DVDs are kinda small by modern storage standards. -- :wq

Just a note: When I got my first DVD writer in February 1998, the price of the writer was 15000 US$ and the price of a media was 80 US$. When I received my first BR writer, the price of the writer was 600 Euro and the price of a medium was ~ 20 Euro. Now the price for a medium is 1.5...3 Euro and the price for a writer is 60...200 Euro. It took 5 years for DVD to get into this price level and it took 5 years for BR to get into this price level. So where do you see a difference? There is another difference: the fact that flash memory has become cheap did change the interest of the people.

Unless you're doing work in particular fields for the recording industry, why touch DVD-R at all? Doing so because it's the official format doesn't really mean anything; the industry and market has been stable for years, and upstream isn't going to switch out everything out from under people using the format.

This is an incomplete list of reports from Launchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/406582 I reported that one, looks as though at least 5 others have the same problem and have found that bug.

There are pointers to Launchpad from other places, too, such as the Ubuntu Forums, Gentoo and Arch wiki and forums and so forth. The only time I ever got 5.1 working was with straight ALSA, but then I don't get upmixing. As a result, I have been using netradio. No closing and opening of the audio device. Also, canberra (the sound notification library) seems to actually output sound correctly, but I think it holds the device open the whole time. I have libcanberra compiled with PA support, so I can use it with other sound sources at the same time. PA isn't changing the configuration back to stereo. It shows 5.1, but media players only output to two speakers until I open the PA control and jump from 5.1 to 4.1 and back. And the players output to PulseAudio directly or through the ALSA emulation? In GNOME 2 you could configure GStreamer (which both Rhythmbox and Banshee use) to use PulseAudio as default sink, or using ALSA; but it PA is running, newer versions will automagically detect it and use it [1]. I use GNOME 3 and PA is mandatory, so I don't remember exactly how it was. I couldn't even tell you. I stopped actively trying to get PulseAudio to work correctly with 6 channel output about two years ago or so, I got sick and tired of people telling me my problem was imaginary. I work around it by using Internet radio, since that way I only have to have the PA control panel program open _once_, instead of every time I change songs. Rhythmbox and Banshee have improved in the past few years in that they no longer close the audio device when playing songs in sequential order. However, that isn't foolproof either. It's been bugging me again lately, but while I have the motivation to investigate and attempt to find a way to fix this stupidly infuriating problem, I don't have the time. Nobody who knows what they're doing with the PA source code seems to believe that this is truly an issue, so it's probably never going to be fixed. Sorry for my curiosity, but it sounds really weird: I have heard a lot about PA problems, but nothing like this.

As for kernel support, once you get past the SATA/AHCI learning curve, it's a piece of cake.

The configuration options include: Seconds between keepalives -- 120 Don't start a shell or command Forwarded port: source port number - PORT Destionation: MACHINE.DOMAIN.COM Host - IP_Address Login - userid Password - pw Using ssh -N userid@IP_Address gives me a password prompt and no command prompt - both good. How do I specify the forwarded port? If I understand correctly, with -L: ssh -L XX:machine2:YY user@machine1 This command will connect you to the machine1 host with user user, and any connection to the port XX to the machine you are running the ssh command from, will redirect the connection to the machine2 host in the YY port. If you want to forward a local port XX to a remote port YY then Canek's suggestion will do what you want, assuming that the correct remote application is listening on port YY. When you have more than one application this can soon become tedious. So, if you want to set up the remote machine as a SOCKS proxy so that any socks-ified applications on the local machine can connect to the remote SOCKS, then you can use: ssh -N -D user@machine1 For applications that do not have built in proxy capability you can use e.g. proxychains. HTH. H'lo Mick and Carnek, The mention of XX and YY wasn't transparent, but a bit of experimentation gave a good connection. Using the terms in my original post, I now have the following working command: ssh -2 -N -L PORT:MACHINE.DOMAIN.COM:22 userid@IP_Address Just need to add an appropriate TCPKeepAlive and all will be good. Thank you both for your tips.. You're welcome. BTW, port 22 in your example above does not *have* to be port 22. As a matter of fact if it isn't, it would avoid zillions of connection attempts by stupid botnets that could drive up your bandwidth consumption. It could also be the same port as the one you use at your local host. Whichever port you choose, you'll have to allow it through the firewall at the remote machine and of course whichever application is running at the remote host that you want to connect to, should be listening on said port. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
