Installazione e Configurazione CUPS

Installazione pacchetto

sudo apt-get install cupsys cupsys-client

Configurazione

Cups <1.2.7 (Sarge)

Per poter accedere all'amministrazione via web da una macchina diversa da quella su cui gira cups, occorre modificare i permessi, contenuti nel file /etc/cups/cupsd.conf:

sudoedit /etc/cups/cupsd.conf
...
<Location />
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
Allow From 192.168.0.0/16
Allow From 10.0.0.0/16
</Location>
...

<Location /admin>
#
# You definitely will want to limit access to the administration functions.
# The default configuration requires a local connection from a user who
# is a member of the system group to do any admin tasks.  You can change
# the group name using the SystemGroup directive.
#

AuthType Basic
AuthClass System

## Restrict access to local domain
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
Allow From 192.168.0.0/16
Allow From 10.0.0.0/16

#Encryption Required
</Location>

Riavviare il server cups:

sudo /etc/init.d/cupsys stop; sudo /etc/init.d/cupsys start

Cups >=1.2.7 (Etch)

Modificare il Bind alle'interfacce

sudoedit /etc/cupsd.conf

#su tutte
Listen *:631

#su localhost ed un'altra
Listen localhost:631
Listen 192.168.149.254:63

Modificare le regole di accesso e disattivare l'encryption (non va ...)

sudoedit /etc/cups/cupsd.conf
...
DefaultEncryption Never
...
# Restrict access to the server...
<Location />
  Order allow,deny
  Allow localhost
  Allow 192.168.*.*
  Allow 10.0.*.*
</Location>

# Restrict access to the admin pages...
<Location /admin>
  #Encryption Required
  AuthType Basic
  Require user @SYSTEM
  Order allow,deny
  Allow localhost
  Allow 192.168.*.*
  Allow 10.0.*.*
</Location>

# Restrict access to configuration files...
<Location /admin/conf>
  AuthType Basic
  Require user @SYSTEM
  Order allow,deny
  Allow localhost
  Allow 192.168.*.*
  Allow 10.0.*.*
</Location>

Riavviare il server cups:

sudo /etc/init.d/cupsys stop; sudo /etc/init.d/cupsys start
