[SOLVED] Can't access CUPS web interface

Hi,
I'm having trouble accessing the CUPS web interface. When I open localhost:631 with firefox I get an "unable to access" error, even though the cups daemon is running with systemd. Any help ?

Hi,

Post your

/etc/cups/cupsd.conf

here in code tags so we can take a look.

Re: [SOLVED] Can't access CUPS web interface

Your /etc/cups/cupsd.conf is the same as mine. Do you have localhost listed in /etc/hosts?

I have this in /etc/hosts...

127.0.0.1       localhost.localdomain   localhost

Re: [SOLVED] Can't access CUPS web interface

My /etc/hosts seems fine :

#
# /etc/hosts: static lookup table for host names
#

#<ip-address>	<hostname.domain.org>	<hostname>
127.0.0.1	localhost.localdomain	localhost
::1		localhost.localdomain	localhost

# End of file

Re: [SOLVED] Can't access CUPS web interface

What does this tell you...

systemctl status org.cups.cupsd.service

If it's disabled, then

systemctl start org.cups.cupsd.service
systemctl enable org.cups.cupsd.service

Cheers
Paul

Re: [SOLVED] Can't access CUPS web interface

The .conf looks okay. What is the output of

systemctl status org.cups.cupsd.socket

?

Re: [SOLVED] Can't access CUPS web interface

Indeed, org.cups.cupsd.socket was active and running but not org.cups.cupsd.service. I followed the wiki though, and it only said to enable the first one.
Anyway, thanks a lot !
