[ilugd] problems after usermod abuse

2008-08-21 Thread Niyaz 
Hello Friend,


I did a mistake :(

I log into ubuntu using the primary user id 'niyaz' (created during
installation).

I was trying virtualbox and on the first run it told me 'niyaz' is not
in vboxusers group.
well, that revelation striked me quite hardly, i guess. 
And i fired:
   $ sudo usermod -G vboxusers niyaz

and it transmigrated me to vboxusers.
I lost the sudo power.

In an attempt to rehabilitate 'niyaz' 
I booted the system with the Ubuntu live disk, 
added 'niyaz ALL=(ALL) ALL' to /etc/sudoers
but it left some challenges for me:

- 'niyaz' can't unlock users-admin (gui tools to manage users) although
users can be added/deleted with useradd/userdel. it exits with error
number 6868.
- similarly 'niyaz' can't unlock services-admin (gui tool to manage
services)
- synaptic package is working fine ('niyaz' is getting authenticated by
it)
- 'niyaz' doesn't have permission to access other auto mounted
partitions.

please suggest me what else i need to do.


Thanks to you all,
Niyaz

Now boot again from live cd and add yourself to admin group.
And the command should have been
sudo usermod -a -G vboxuser niyaz

On a terminal running in X, do following

$ xhost +si:localuser:root
$ sudo su -
# export DISPLAY=:0
# users-admin

Now in the Users Administration dialog box, navigate to Privileges box and 
grant appropriate privileges. All of these privileges are actually groups, 
user should be in. Now, after granting appropriate privileges.

# exit
$ xhost -si:localuser:root

You forgot the -a (append option ). The -G removed you from every group
except the vboxusers. 

 
 and it transmigrated me to vboxusers.
 I lost the sudo power.
Why you lost the sudo power ? Because you were no longer a member of
the admin group. (Read the sudoers file) 

My user 'jasbir' on my Ubuntu system is member of the following groups 

$ groups
jasbir adm dialout cdrom floppy audio dip video plugdev fuse lpadmin
admin pulse pulse-access

Make sure you are member of admin and your own user group named niyaz.
For more info regarding the purpose of the various groups
read /usr/share/doc/base-passwd/users-and-groups.*

 In an attempt to rehabilitate 'niyaz' 
 I booted the system with the Ubuntu live disk, 
 added 'niyaz ALL=(ALL) ALL' to /etc/sudoers

When everything starts to work fine you should remove this line and
check again.

Forgot to add. Edit /etc/groups file on the installed ubuntu. maybe
you can do it from single user mode too.
Also, you can use gpasswd instead of usermod.
gpasswd -a niyaz vboxusers
