PAM is a pain in my ass and I just wonder if it is really necessary to have it installed. If not I will be glad to recompile hole my system to have a PAM/pain -free system.

Right now I suppose PAM is responsible for my Alsa/sound permissionproblems that force me to do a "/etc/init.d/alsasound restart" after every boot, and that's not my first problem with PAM.

That seems odd....

:?

What make you think PAM is responsible?

PAM should only come into play if your logging in/changing user......

PAM messes with device permissions.

if it's any use, i've not used PAM for a very long time and i'm doing alright. drop it, and then UDEV can be the pain in your ass.

Are you using a '-pam' flag in your make.conf or have you just skipped to installed the Pam application?

My problem with Alsa started after the latest upgrade to alsa-headers-1.0.8, alsa-lib-1.0.8, alsa-utils-1.0.8, and alsa-oss-1.0.8-r1. "/etc/init.d/alsasound restart" changes the permissons in the /dev/snd/ directory to useful ones.

Try removing/modifying this line from '/etc/security/console.perms':

Code:

<console>  0600 <sound>      0600 root.audio


Might save you having remege your whole system.

Didn't know PAM messes with permissions in this way. It seems a bit redundant when you have things like udev, etc......

You can make pam stop messing with device permissions. The file to see is /etc/security/console.perms. Also "man 5 console.perms"
I agree that pam is overkill for a home user. But at the moment ripping it out just looks like even more hassle than configuring it.:lol:

I'm going crasy...
This early morning then I started up the sound worked as it should. The permissions in /dev/snd and /dev/sound was the same - magnus:audio - which didn't work yesterday. The things I have change since previous boot yesterday was changing my icons becuase of a Glib errormessage (about that: read this tread) and cleaned out my old Xfce4 configfiles from ~/ then I tried to find a solution for the Glib error. But whose configs worked before upgrading Alsa.
Next boot will show if my luck will consist.....

Hi,

I would also like to disable PAM, because I don't have any use for it. Is it just enough if I add -pam in my USE flags and recompile these packages in my system?

Code:
xxxxxx root # equery hasuse pam
[ Searching for USE flag pam in all categories among: ]
 * installed packages
[I--] [  ] app-misc/screen-4.0.2-r1 (0)

add -pam to your USE flags, emerge --newuse --deep -av world && emerge -av depclean

theres a thread about removing PAM somewhere.

Thanks for that tips. Even if it seems that PAM wasn't responsible for my Alsaproblem I found PAM useless for my needs and a troublemaker.

what should i do about this error? and also is it safe to R remove openssh...gcc....portage...nitro-sources.......dam they are going to be removed if i remove PAM?

Code:
TB0x xb0x # emerge --newuse --deep -av world

These are the packages that I would merge, in order:

Not removed - replaced with the newcompiled version.
Just for your nowledge: the * shows which USE-flag changes who has been done compered to the old compile. Many of you package had no pam-flag but other flagchanges as you can see.

I got a new real stupid problem then i wrote -pam in /etc/make.conf. Portage doesn't recognise the change so "emerge info" shows pam as active. I had to set it manually during the emerge.

About my Alsaproblem: Now I have sound but no mixer. :-(

pam is a really cool thing, lot's of people don't understand what pam is supposed for, then prefer to get rid of pam, a bad idea IMHO.

ppl blame pam when things managed by udev got messed, but isn't udev pam-aware?
looks like a udev fault, not a pam fault.

maybe this link shoud be helpful for all these pam haters.

@cs02rm0
if you dont have that file, it means pam_console isnt installed on your system and pam doesnt do anything with your device permissions ;)

PAM = username/password
UDEV = /dev/* permission

look in /etc/udev/**, edit, and/or add your account to 'audio' group... if it doesn't help... sorry, you're the admin.
