ripristinare /dev [era: Re: problemi installazione at]

Non posso nemmeno scrivere in /dev/null senza privilegi di root...
il file /dev/null e' un file particolare:
ls -l /dev/null
crw-rw-rw- 1 root root 1, 3 2007-04-11 09:17 /dev/null
qualcosa ha cambiato i privilegi di /dev/null ?
a me e' successo piu' di una volta, specialmente quando facevo un
upgrade del kernel; in generale e' sufficiente rimettere i privilegi di
/dev/null corretti. Qualche volta succede che all'avvio della macchina
vengano ripristinati i privilegi sbagliati per /dev/null. (si fa con
mknod)
Hai ragione, grazie.
Dimentico sempre di controllare le cose ovvie.
Comunque ho notato che anche sshd ha dei problemi:
error: open /dev/tty failed - could not set controlling tty: Permission
denied
Infine, un altro problema:
sshdPRNG is not seeded
Sembra che /dev sia messa male (sono sotto Xen)...
