Apres avoir modifier mon /etc/hosts en rajoutant la ligne "127.0.0.1 localhost" comme ceci :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#host2:
# The following lines are desirable for IPv6 capable hosts
# (added automatically by netbase upgrade)
127.0.0.1 localhost
::1	ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Le message d'erreur a disparu au boot mais quand j'essai d'imprimer, j'ai ca :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
nc@amaroli:~$ lpr fichier
Status Information:
 sending job 'nc@amaroli+273' to lp@localhost
 connecting to 'localhost', attempt 1
 cannot open connection to localhost - Network is unreachable
Make sure the remote host supports the LPD protocol
and accepts connections from this host and from non-privileged (>1023) ports
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Vous y comprenez quelques chose vous ? Parce moi je nage... :(

Comment faut-il modifier /etc/hosts ? Qu'est ce qu'y cloche ?
J'ai l'impression que tout ceci est la base de tous mes soucis (imprimante qui n'imprime pas et scanner accessible qu'en root)

J'ai besoin de votre aide...
Merci infiniment,
Coolman
