copiare gruppi di appartenenza utente

Understanding /etc/group file

cdrom:x:24:vivek,student13,raj


molto interessante anche questo:

migrate user accounts

~~~~~~~~~~~~~~~~~~~

da feisty su virtualbox: utente std base appartiene a questi gruppi:


$ cat /etc/group | grep zagor



adm:x:4:zagor

dialout:x:20:cupsys,zagor

cdrom:x:24:haldaemon,zagor

floppy:x:25:haldaemon,zagor

audio:x:29:zagor

dip:x:30:zagor

video:x:44:zagor

plugdev:x:46:haldaemon,zagor

lpadmin:x:109:zagor

scanner:x:111:cupsys,hplip,zagor

zagor:x:1000:

admin:x:114:zagor

in definitiva quindi, basta aprire il file /etc/group con distro live e editarlo assegnando l'utente davide ai gruppi std, cosi' dovrebbe tornare a posto, senza toccare /etc/sudoers.

controllare anche che lpadmin sia espressamente dichiarato per davide, altrimenti siamo punto e a capo con cupsadmin

ho distrutto sudo!

Nel seguire la guida http://www.cups.org/articles.php?L237 con troppa fretta ho lanciato

usermod -G printadmin davide

questo ha cancellato tutti i gruppi di appartenenza dell'utente e quindi sudo non funziona piu'.

root non e' abilitato e non ho altri utenti sul sitema.

che fare?


idea: avvio con una live, accedo al file etc/sudoers e aggiungo l'utente "davide" ai sudoers.

poi, se funziona sudo, dovrei poter aggiungere tutti gli altri gruppi del default.

speriamo in bene...

How to allow more sudoers

• Read #General Notes
  

EDITOR=gedit sudo visudo

(nota: visudo e' un comando che edita il file /etc/sudoers in modo sicuro,
bloccando il file con un lock /etc/sudoers.tmp e controllando la sintassi
prima di salvare. la definizione della variabile EDITOR e' perche' di base
visudo apre il file con vi)

• Append the following line at the end of file
  

system_username ALL=(ALL) ALL

• Save the edited file
  

OR since everyone in the admin group can use sudo:

sudo adduser a_username admin

This appends the admin group to the user's supplementary group list. They will now have sudo access.

EDIT: this link possibly best: 2nrds.com.
Card should be same as Pinnacle PCTV Hybrid Pro Stick (320e) (USB ID=eb1a:2881).
Card option could be (link for kernel 2.6.29):

53 -> Pinnacle Hybrid Pro
1 -> Unknown EM2750/28xx video grabber
52 -> DNT DA2 Hybrid

EDIT2: the latter link seems to work up to Hardy, maybe not on Intrepid http://ubuntuforums.org/showthread.php?t=956353
EDIT3: with kernel >2.6.24 see this article on HTPCpoint (in Italian)

EDIT4: from Pinnacle web page:


PCTV Hybrid Pro Stick (320e)
