Need explanation about all groups

Hi everyone,

I can't administrate my system without knowing each group. Help me, please. I searched for 30 minutes and now I'm bored.

These are my groups in Slackware 11:

Code:

adm
audio
bin
burning
cdrom
console
daemon
disk
floppy
ftp
games
gdm
kmem
lp
mail
man
mem
mysql
news
nobody
nogroup
pop
root
rpc
scanner
shadow
slocate
smmsp
sshd
sys
tty
users
utmp
uucp
video
wheel

My second question is:

In which groups should a user be to burn. The group "burning" doesn't help. Thx.

Code:

/usr/bin:
-rws--x--- 1 root buning 572308 2006-11-26 10:06 cdrdao
-rws--x--- 1 root burning 317404 2006-11-26 10:03 cdrecord
-rws--x--- 1 root burning 78052 2006-11-26 10:08 growisofs

To find out which group protects which ressource, as root, type (in this example the group is "adm"):

Code:

find / -group adm 2>/dev/null

Second, these are my groups and cd writing works:

Code:

pu@slackw:~$ id
uid=1000(pu) gid=100(users) groups=6(disk),17(audio),18(video),19(cdrom),20(games),93(scanner),100(users)

Thx a lot, burning works now. And now I see, the group rights are nothing as file rights, right?

Thx.

So what was missing?
And where does this "burning" group come from? It's not in my install.

AFAIK, yes.

Hi,

I created a group called burning and used the k3bsetup program which changed the group and permissions on the three needed console burning tools. And all I got to do was add my user to the groups you told. Finished. My user was only in the group users.
