[gentoo-user] Video Network Stream from Pipe
Hi! I'm currently trying to set up a personal video recorder in form of a headless server using mencoder and freevo. What I would like to do is watching the movie while mencoder is realtime encoding it to x264/vorbis in a Matroska container. I already tried it using sshfs. Unfortunately, the file is only read up to the point where it ended when playing it started. I don't know if NFS would behave better. Well, what I thought about was doing it like this: #!/bin/bash mencoder [...] -o - | tee video.mkv | stream-app So far it should work and vlc would be the natural choice for the streaming app. However, vlc seems unable to read from a pipe so I need something else. Can anyone give me a tip? maybe I missed an option in vlc or can someone propose an app that can be used instead? By the way: It's a 100MBit ethernet network without any switches or hubs. The machines are right next to each other. I hope it will be a 400 or even 500MBit net soon, but that's another topic ... signature.asc Description: This is a digitally signed message part

I just want to give an update in case someone plans something like this: NFS does not have the problem sshfs had - problem solved. However, you can't navigate through files that mencoder did not yet finish muxing. To be able to do so, you must tell mplayer to create a new idx with -forceidx (just -idx might work as well and shouldn't harm files that already contain an index but I haven't tested it yet). signature.asc Description: This is a digitally signed message part

Buy four disks and build a RAID1 using Linux device mapper. Since the data sent to the devices is not replicated on a RAID-controller (e.g. after transfer through PCI) but in software, you'd send four times the amount of data through your poor old PCI-bus. signature.asc Description: This is a digitally signed message part

I'd use reiserfs3.6, maybe even without notail to make it more space efficient. I'd also use ext2 on /usr/portage. These data don't need journaling. Everything's got an MD5-sum to make sure it's unchanged after a crash and you can easily resync. I found ext2 with 2k blocks to be faster than reiserfs3.6, even on read-performance. If I were you, I'd also use separate volumes for /tmp and /var/tmp (without ccache) with xfs. /home could use data=journal. Those data are precious and if I remember correctly, this setting even brings an obscure (i.e. undocumented) speed improvement with many parallel disk accesses, for example in a multi-user environment. signature.asc Description: This is a digitally signed message part

I don't think there's alot to do when creating a reiserfs. You could change the number of blocks for the journal. A bigger journal allows larger transactions which speed up write actions but might waste space. If you've got a second hard drive you could use an external journal but I've never done any benchmarking on that issue although I use it on my personal wannabe server (a raid1 and a single disk for the journal and unimportant data). I didn't comment on /var because I don't know how you use it. I suspect it to hold alot of temporal data like lock files, spools and so on. So there's a lot of creating and removing files going on, possibly in parallel. XFS is good in parallel and in creating files but terrible in removing files. Reiserfs with notail seems a good choice if you ask me (what you did ;) ) I'd also use ext2 on /usr/portage. These data don't need journaling. Everything's got an MD5-sum to make sure it's unchanged after a crash and you can easily resync. I found ext2 with 2k blocks to be faster than reiserfs3.6, even on read-performance. I've already made the partition as suggested in [1] I used this command: $ mke2fs -b 1024 -N 20 -m 0 -O dir_index I guess 1K block size would be faster?? I'm not sure. 2K blocks might reduce fragmentation. If you look at the output of find /usr/portage/ -type f | xargs du -h --apparent-size you'll see that there are quiet a few files larger than 1K but most are smaller and might stay that small. So yes, I think 1K is a good choice but you won't loose much with 2K, maybe you even gain some speed. If I were you, I'd also use separate volumes for /tmp and /var/tmp (without ccache) with xfs. What did you mean by 'without ccache'? I have ccache and I use it... I meant that you should keep ccache on a separate partition. I just think: Less stuff in the FS, less work on allocation and lookup, more speed. And there's a lot of stuff in 2GB ccache. By the way: I don't think /var/tmp is a good place for ccache (not technically, just for the sake of layout). I've moved it to /var/db since it's not really a bunch of temporary data but more like a changing database. /home could use data=journal. Those data are precious and if I remember correctly, this setting even brings an obscure (i.e. undocumented) speed improvement with many parallel disk accesses, for example in a multi-user environment. it's done, thanks, BTW what's your home partition FS? your choice is ext3 or reiserFS?? I use reiserfs3.6 without notail but that doesn't mean that it would be a good choice for you. I'm on laptop and disk space efficiency is a big topic for me so I use tail-packing wherever suitable. And yes, I am a fan of ReiserFS-3.6. I think it's the best multipurpose FS. You can easily adapt it for high performance or high disk space efficiency. If its journaling would be as good as Ext3's data=journal I'd use it everywhere except for small partitions (ext2) and big files (ext3 and xfs). One last thing, since I'm on LVM resizing the partition is a must feature, in ext3 I use resize2fs which works quite nicely, is resize_reiserfs as reliable as resize2fs is?? Yes, it's just as good and the sky's the limit for resizing :) Oh, by the way: If you choose to use XFS somewhere, keep in mind that you can't shrink and XFS-FS. Neither online nor offline.

You could use the noatime mount option on all your partitions. With atimes enabled, every time you read a file, its (mostly useless) access time is updated which results in a write action. The only program that I know to use atimes is mutt (for mail spools only). You could also take a look at the link I've posted in my last message.

The new Macbook Pro wireless drivers (I bought my machine in late October 2007, just when Leopard came out -although, well, I found myself almost never using it) required SVN version of madwifi (dunno if now the stable version works, will check when upgrading kernel), and so far attempting to set power saving on my wireless card fails. The Macbook Pro also has a nvidia video card. The nvidia drivers work quite well (apart from some issues with external dvi resolution), but as far as I know, on it the Powermizer feature is somehow disabled. :( I guess both things combined can explain at least a significant quantity of the power drain. Suggestions are much welcome, I hate the reduced battery power. m. 1. Use laptop-mode if you don't do it by now. Really nice even without its delayed disk write feature. 2. Displays are by far the biggest energy consumers. Lower its brightness as far as possible. Some laptops even allow you to switch its backlight off - very nice if you are outdoor. 3. Use the powersave-governor. If you really need the additional power ondemand offers, try the conservative-governor. It increases the clock rate slower than ondemand and might stop it from jumping too fast too high. 4. Try sys-power/powertop. It shows you processes creating a lot up wakeups for the CPU. It also gives you tips on your kernel config. 5. Sometimes a BIOS update helps... Hope this helps. signature.asc Description: This is a digitally signed message part
[gentoo-user] Tweak nice
Hi! I noticed a very annoying behavior. I've got a headless server (Athlon 64 X2) which primarily acts as a personal video recorder using mencoder and at-daemon. In its idle-time it's supposed to run a dnet-client. Then I've got a laptop (64bit Celeron, single core) on which I play those video files from my server over NFS. So far, so good. My problem is: Neither of them can handle recording/playing video while there is any background activity. That means I have to stop the dnet-daemon and suspend any emerges on my laptop. If I don't, both mencoder and mplayer loose sync of audio and video and drops frames. Apparently a nice-setting of 19 is not enough to keep daemons and similar stuff as strict idle activity. It still gets a fair amount of cpu-time. Of course, I could give mencoder/mplayer real-time priority (nice -n 20) but that would need them to run in super-user mode which should be unnecessary for such a simple task. Long story short, can I somehow tweak the scheduler to be more aggressive when it comes to high nice-levels? Thanks in advance!

I would expect most people these days to be receiving some kind of digital signal - DVB-T using an aerial, DVB-S using a dish or DVB-C via cable. Here in the UK, for example, it would be most common to receive DVB-T Freeview. Receiving a digital signal requires no encoding, practically no processor resources, as the DVB signal is just mpeg, and the card is simply dumping the stream to hard-disk. Are you playing back the video across the network? What processor / RAM configurations do your PCs have? What hard-drives? What size are the videos (pixels) and what format (encoding, bitrate) are they stored in on your hard-drive? I think you have to demonstrate that the problem is processor-bound. My immediate thought upon reports of stuttering is to question disk or network throughput. Stroller. It's a PCI-card for analog TV (ordinary cable with about 20 channels). It doesn't output mpeg but raw video/audio so I have to encode it. I use h.264 (1 pass, 2 threads) and lame. The settings are tweaked to allow 25fps and a good overall quality. I could give you the settings but I don't think they're really important. The load is somewhere around 1.3 to 1.8. Of course I could tweak it to achieve 25fps even with dnet-client in the background but that would cost me quality and wouldn't fix my problem on the notebook. On my notebook, CPU-utilization is just around 50%. There is no apparent bottleneck on my setup. The 100MBit network is fast enough to transfer the files while playback is running even without caching. I'm decoding them on my notebook. If there were a bottleneck other than CPU-scheduling, it would hit me every time, not just when another process demands CPU-time. signature.asc Description: This is a digitally signed message part

If you run dnetc with nice 19 and simultaneously something that uses as much CPU as it can get (like a fractals generator) at nice 0, you will see that dnetc still uses around 6% CPU. But it does go down to 6%. The remaining CPU should be enough for watching video. Disclaimer: I have never used mplayer on a 64bit system. It might have issues there. Since you are playing the video over NFS you do so over the network. Maybe a stupid question: You do use FastEthernet without any hub, right? Switches are alright but hubs are evil. A possiible work around might be to increase the buffer in mplayer to something around 1MB. Uwe Yep, I meant dnetc (I thought dnet-client would be better understandable). And yes, it does go down but not far enough, especially because there are two such processes (one for each core). By the way: Another daemon who's causing problems is clrngd, creating 100% CPU-utilization every 4 minutes for about 1 minute. I neither use a switch nor a hub, just a good old crossover cable. In fact, I used to let mplayer create a 8MB cache but without background activity it was useless and with it, it's got eaten up too soon. Mencoder seems to utilize a queue/fifo/whatever-you-might-call-it by default but that doesn't help if it doesn't reach 25fps.

[gentoo-user] Initrd-script questions
Hi list! I'd like to have some advice on my situation: I have a custom init-script (derived from genkernel). What it already does is to let gpg ask for a passphrase to decrypt a file on /boot and then to use to content of that file as the key to a LUKS-formatted swap (logical volume) which is then used to resume from disk. What I would also like to do is to use the very same key for other lvm-volumes like /var and /var/tmp but that doesn't seem that easy. First idea: Just do the same as with the swap-volume. However, all other mappings are gone after resuming/booting. Second idea: Write the plaintext-keyfile to /boot and then use it via /etc/conf.d/cryptfs before removing it in a secure manner (srm, provided by app-misc/secure-delete). Problem: When resuming, /boot is already mounted. Writing to it and then resuming leads to filesystem corruption. Third idea: Using a dedicated volume for storing the plaintext key. Cumbersome, doesn't reduce the risk that srm isn't enough to protect the key. So ... what I'd need is a way to transfer data between an initial ramdisk and the real init. Ideally in form of tmpfs-mountpoint. I don't think my odds are very high but I just wanted to ask... Thanks in advance!

Yes, lowering the rate to a slower speed will help greatly.
The lower

forms
better connects over long hauls.

I use wireless-tools from portage. In it is iwconfig. A simple man
iwconfig
will show you what you need. Other thing you could do is configure the
Wireless AP for a fixed rate... works for me.
I found this:
rate_wlan0=( 5.5M )
which isn't documented in net.wireless, but it doesn't seem to have
any affect. I've tried it on the router and the client which uses
wpa_supplicant. I still see the rate on the client fluctuate all the
way up to 54 Mb/s in the output from iwconfig. The router's rate is
always reported as 0 kb/s.
- Grant
It appears 'iwconfig wlan0 rate 11M' works (at least as far as the
output from iwconfig is concerned) but how can I set /etc/conf.d/net
to always use this rate?
- Grant
The best way I found to do this is to just write your own script and run
it at the default runlevel. write a script called wireless-up save it in
your /root directory. Then in /etc/conf.d/local.start add the script
name to the list: /root/wireless-up. Make sure the script is executable
with chmod 666 /root/wireless-up. Here is what mine looks like. I laugh
when I read this thing that I call a script. I'll be upgrading this in
the future but for now maybe someone has a better idea and/or script.

For custom scrips, you can add a preup, failup or postup-function

Keys for urandom work great for /tmp and swap but how should I use this for a partition which is supposed to keep its content between reboots? I thought it would work with the following settings: /etc/conf.d/cryptfs It's /etc/conf.d/dmcrypt nowadays. Interesting, why is there no hint that cryptfs is deprecated/obsolete? target=var source='/dev/mapper/vg-crypt_var' key='/boot/key.gpg:gpg' target=var_tmp source='/dev/mapper/vg-crypt_var_tmp' key='/var/lib/tmp_key' I've read the warning in /etc/conf.d/cryptfs about /usr on a separate partition and followed their advice. Which warning, btw.? Works just fine here. # Note when using gpg keys and /usr on a separate partition, you will # have to copy /usr/bin/gpg to /bin/gpg so that it will work properly # and ensure that gpg has been compiled statically. # See http://bugs.gentoo.org/90482 for more information. However, the setup doesn't work. I'm not asked for the passphrase, the mappings are not created. What did I forget? That the mappings are created all in one go before anything is mounted, so you can't put the keyfile for /var into /boot. The only thing that would work is to put the keyfile on the root fs, because that's the only one that is mounted when the mappings are created, like: target='c-usr' source='/dev/evms/usr' key='/etc/crypt/keyfile' Bye...

Duplicity also does incremental backups, but it's still slow. Using dar, would I have to manually (or per script) use gpg to encrypt the archives? I use GPG instead of DAR's build-in encryption because asymmetric encryption allows complete automation of the backup process, e.g. you don't have to store the key as a plaintext file or type it at every backup. And yes, you need a custom script. For incremental backups to work you would need to make an isolated catalogue (dar's nomenclature) in order for it to see which files and timestamps are already backuped without decrypting the archive. Tar uses a similar approach. The alternative would be an encrypted filesystem and rdiff-backup or rsync. Optionally you could safe the key to the filesystem on your home partition or, if it doesn't need to be automated, in a gpg-encrypted file. An encryted filesystem and rdiff-backup or similar was another option I though of. The problem is restoration: Would I easily be able to restore the backups from a freshly installed system? AFAIK cryptsetup is part of Gentoo's stage3. Most live-CD's I've tried had support for it, too. Commonly they also offer all common encryption modules for the kernel and GPG, so I wouldn't worry about this. Just make sure to keep your key and everything you need to decrypt off site. I myself store my GPG-key on a server, my parent's PC and my USB-stick. Since rdiff-backup stores all its internal data in a single directory, (.rdiff-backup, I think) you could still access the last snapshot of your system even without the program itself. signature.asc Description: This is a digitally signed message part

If I decide to use the backups on a remote server too, I'll probably stick to backing up to the local server and then using rsync. It makes sense to have a copy of the backup locally and only use the much slower option of restoring from a remote host when absolutely necessary. There are at least two drawbacks to using rsync for mirroring the local backup to a remote host: - If your local backup becomes corrupt, then so does your remote backup, except if you are quick enough to disable the rsync step. That's why I use rdiff-backup. - If you have disconnection during the rsync step (happened to me last night), your remote backup is temporarily corrupted. For the second problem, I'm toying with the idea of writing an rsync-like tool for mirroring one big file to a remote server, by first transmitting the changes and storing them separately on the remote machine, then performing the update on the big file after the connection has closed. Shouldn't rsync do this on its own? There is an option --inplace described with: This causes rsync not to create a new copy of the file and then move it into place. Instead rsync will overwrite the existing file, meaning that the rsync algorithm can't accomplish the full amount of network reduction it might be able to otherwise (since it does not yet try to sort data matches). One exception to this is if you combine the option with --backup, since rsync is smart enough to use the backup file as the basis file for the transfer. This option is useful for transfer of large files with block-based changes or appended data, and also on systems that are disk bound, not network bound. The option implies --partial (since an interrupted transfer does not delete the file), but conflicts with --partial-dir and --delay-updates. Prior to rsync 2.6.4 --inplace was also incompatible with --compare-dest and --link-dest. WARNING: The file's data will be in an inconsistent state during the transfer (and possibly afterward if the transfer gets interrupted), so you should not use this option to update files that are in use. Also note that rsync will be unable to update a file in-place that is not writable by the receiving user. signature.asc Description: This is a digitally signed message part

[gentoo-user] Best practices - flexible XServer
Hi list! I found my current XServer-setup very inflexible and would like to hear some tips for improving it. What I would like to have is a customizable plug'n'play setup which I can configure without restarting the XServer. Since I have a notebook, there are many occasions where I have to work with hardware I don't know and on other occasions I need to use my own peripheral devices as good as possible. So I need to customize my setup for the devices I use every day without breaking compatibility with unknown standard hardware. So, what's the best way for configuring 1. usage of my own Logitech mouse as well as typical USB-mice and my touchpad. 2. USB-keyboards as well as the build-in, all with custom multimedia and Fn-keys. 3. external displays (VGA, DVI, LCD and TV-Out, one at a time would be enough) with different aspects and resolutions with 3D-acceleration on my Intel i945.

Is there a way to monitor it's health in the external enclosure until I get my new laptop? Is counting the bad sectors enough?

Last week I had my own notebook hard disk (60Gig as well) dying on me: Bad blocks on a single partition, strange noises from time to time and the S.M.A.R.T offline self test aborting with read error before it even started. I found smartmontools (or anything that's just polling SMART) inappropriate. They still reported all is well although the self tests failed (and were logged as failed) and an overheating occurrence was logged (half a year ago the disk reached 53°C during normal operation for no apparent reason). Bad blocks were not registered at all! signature.asc Description: This is a digitally signed message part

I'm not entirely sure but I suppose x86 means anything from i486 upwards (Gentoo doesn't support i386 anymore). If you can't find a Gentoo live-CD for i586, you could try Damn Small Linux (DSL). signature.asc Description: This is a digitally signed message part

Convincing people that Gentoo is alive becomes tricky because the final is months late and little motion on the home page. That's about all most people inspect. So bottom line, impressions of Gentoo are going south even before we test. Some sort of progress bar or chart showing bugs squashed and new reported, maybe?? At least some kind of ticker showing expected final release date? Counting lines of code or something? Personally I don't care when final ships - just knowing present expectations or status with an easy home page glance is all I ask.

These numbers show clearly that Gentoo is very alive.

Having a user friendly website that also caters to the needs of newcomers to the Gentoo scene, requires that the key features and benefits of Gentoo are easily visible/accessible. Not many people will navigate to hidden Statistics pages to draw their own conclusions. These could be users that one day prove valuable contributors. I suggest that we spring clean the website and consider our new visitors needs at the same time (plus things like the much asked for Documentation search field?). ;-) Just my 2c's. Yep, gentoo.org really seems to have been created from devs and users for devs and users. There is nothing like a Features page or Why to choose Gentoo for newcomers. Heck, you have to search hard to even learn whether it is suitable for desktops or servers! Just compare ubuntu.com with gentoo.org, for example.

[gentoo-user] High Definition and OSS
Hi list! I'm thinking about buying a BlueRay- and HD-DVD-combo reader. Can I use GNU/Linux standard software (mplayer preferred) to watch HD-movies or does its copy protection stop me from using it? If so, are there any workarounds? Thanks in advance! Florian Philipp signature.asc Description: PGP signature

Florian Philipp I think you have to run software to decrypt the DVD on the fly and then have mplayer read the stream. The decryption keys to older bluray titles are available but newer ones might need to be decrypted (rip the movie to your harddrive). It is definitely not easy right now but a lot of titles are being cracked everyday. I would avoid bluray until it gets easier to play. Hmm, on which features depends the encryption? Would a Windows Media Player in Wine be able to play it or do I need an operating system supporting it, maybe in a virtual machine? Has anyone tried? Why would you buy an HD-DVD reader? That format is dead and there won't be any new titles. It's meant for my dad. He's a big Star Trek fan and afaik the new remastered Star Trek Original Series is HD-DVD-only. The price difference isn't that big, either. signature.asc Description: PGP signature

[gentoo-user] Java default Swing stile
Hi list! I've recently started both programming and using some Java applications (not that I would have a choice ...). Well, anyway, as it seems the default style for Swing is set to Metal, Java's own rather ugly and non-conforming variant. Is there a way to set this to GTK, QT or whatever I have here other than through the functionality in the programs themeselve? Or is it really the Java-VM who's dictating what's the default for a given platform (Windows/Linux)? Thanks in advance! Florian Philipp signature.asc Description: PGP signature

Since I'm only going to be using it a few times a month, I'm not too worried about benchmarks, unless an implementation is excruciatingly slow. I only need a runtime. I don't know the programming language, so there's no need for a full-blown development environment. Take Sun JRE.
