Recent Linux kernels support fcaps in the filesystems and "somebody" evil, who knows what he does may even set up fcaps on executable files when the related support-software is not installed, just because the unstable kernel interfaces are accessible from libc. Do you like people to be able to open security holes? You don't know what my intentions are and why I want to disable libcap. I have my reasons. This happens because it is actually possible to disable it. If you really don't like that, then you should probably make libcap mandatory. Assume it's there, and if it's not, the user should get compile errors. But as long as it's not mandatory, I have my reasons why I would want to disable it, just as I have my reasons why I would want to explicitly enable it. What if autodetection fails? If I use the appropriate "enable libcap" flag, and libcap is not there, or it's broken, or whatever, I don't want to get a build that's now insecure. I want the build to abort with a big, fat error. I think you're too used to binary distros and Solaris to appreciate the different requirements of source-based distros :-)

I tried to do so but failed when trying to mount the filesystem. following error occured: The device '/dev/sda1' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around? I'm using a brand new ssd. there has neither been installed a filesystem before nor did I create a NTFS partition. does the error occur because the livecd is using kernel 3.7.10 and f2fs is only available with kernel 3.8.X and later? If so, could I just try to install gentoo based on another livecd which is using kernel 3.8.X? thanks for any replies. Von Samsung Mobile gesendet

It's just for audio so you don't have to muck around with everything else (but OpenElec is a great option if you want a media center).

Re: [gentoo-user] Stream Audio to RasPi on LAN
I personally have this setup running on Windows on my home network. XBMC has uPNP built in which allows streaming to or from my home theater setup from either my Android phone or another uPNP machine on my network. It's by far yhe easiest solution I could come up with. Even lets me stream 1080p movies. I'm sure a similar setup could be achieved with the linux version of XBMC. There's even a specific version for the Pi.

OK, I could create such an option. I just don't like people to be able to do this without knowing that there is a potential security problem if the cdrecord binary has been assigned file caps but cdrecord doesn't understand that it is running with enhanced privileges.

[gentoo-user] Stream Audio to RasPi on LAN
Hey guys, I have a nice set of speakers, but they aren't near my desk in my home office. I used to carry them back and forth when I wanted good music, but that was a pain. I currently have a RasPi running arch connected to the speakers -- I've been cat-ing audio files over ssh to mplayer, and that mostly works (no fast-forward/skip). I also tried using reverse-ssh and sshfs to mount my files on the RasPi, but that seems silly. What I really want is to be able to stream audio from my browser to the RasPi's speakers (pandora, grooveshark). I'd like to set up an audio device that maps to the RasPi. Something like /dev/dsp1, perhaps. If I could have some audio sent to the RasPi and leave mcabber's chat notifications on my laptop's speakers, that'd be fantastic. Does anyone have a setup like this? Know of any good options? Randy

If you change the permissions in /dev/snd, I don't think PA can work properly. Could you please set your system to the default setup (doing a backup of the relevant files)? Leave the permissions of /dev/snd/* as the kernel sets them, use the original configuration files under /etc/pulse, and don't use the system-wide PA daemon. Then log in into the console, try to use an application that uses the soundcard (preferably something simple, like mplayer), and see if PA is running. If it is, please paste the output of "pactl list". If PA it's not running and you get no sound, then the problem is elsewhere.

You can enable it by default if you wish. As long as it is possible to remove libcap from the system the security hole you are talking about is still there. The option does not change anything. Currently one could still compile cdrtools without libcap and afterwards install libcap and use setcap on cdrecord et al. which leads to the same problem. -- Regards Daniel Pielmeier

Recent Linux kernels support fcaps in the filesystems and "somebody" evil, who knows what he does may even set up fcaps on executable files when the related support-software is not installed, just because the unstable kernel interfaces are accessible from libc.

This is however not the case. We live in a universe that has plenty of distros and plenty of different operating systems. Good OpenSource software is written in a way that allows it to run on as many platforms as possible. This goal however is in conflict with the text in the "automagic" article. There are platforms that do not offer specific features, libraries or similar at all. Portable software automagically adopts to what it available. My software is "very" portable and for that reason is careful to always automagically detect what's present. Also, my software currently does not depend on non-basic features. If I e.g. start to continue with xcdroast, things may look different. In general.

Does this give a clue? Not really; as I said, the PA documentation clearly says that if you use system mode "You are on your own. You need to know you way around, be able to write init scripts, dbus policies, to fix up device permissions, and unix users, you need to pass around security cookies and more." I haven't ever used system-wide PA. I think of the following; try to delete both /root/.pulse and $HOME/.pulse, and rebooting (probably a logout/login should suffice, but you never know). Another thing: if you installed PA since GNOME 3.8 needs it, why are you using it without GNOME? If you use GNOME, the session manager will automatically start PA as a user for you, and everything should work. If you are not running GNOME, why do you run PA? If you are at the console without X running, just don't use PA. Use mplayer -ao alsa or whatever. Or do you want to run several audio apps in the console? >>> >>> I want to run apps from the console, but to start gnome when I need it. >> >> Then do that.

Or is there > some other way to make this happen? I don't understand the question. If you don't run PA by yourself, then it will be started only when using GNOME. And if you are using GNOME, you can use the nice sound settings dialog to get your sound. If you don't start GNOME, then PA will not be started. If you don't have sound in your console even without PA running, then is for some issue completely unrelated to PA. PA should not be started if you only log in through the console. Unless you are still running it syst

Could be,I used grub-legacy for a while in the past and found it not so good too.Hard to configure as I wanted.
