user and groups problem

katto · 12-11-2010, 01:12 PM

I'm running debian lenny and I was trying to add my user account to the usergroup games. So I opened up a root terminal and did

Code:

usermod -G games a

which removed all my other groups. I added them back with the same command right after.

The problem is that the group command does not show me in the games group. When I type

Code:

groups

which gives the groups of the current user it prints out

Code:

a dialout cdrom floppy audio video plugdev netdev powerdev vboxusers

but when I type

Code:

groups a

it prints out the correct groups

Code:

a dialout cdrom floppy audio video plugdev games netdev powerdev vboxusers

It seems as if I have created a new user with the same id as my user account. Is this possible? Or do I have to logout and login again for it to work?

PS: I did learn eventually that I need to type usermod -a -G to retain my old groups.

In order for groups to take effect you do have to login again. `groups` without parameters shows your currently active groups (which should generally equal your groups but in this case doesn't for obvious reasons).

Well, you're right, changes in the groupmembership take effect after the next login.
