AND the 127.0.0.1 turns into my ip local address, i.e, 172.xx.xx.xx!??
1) changing /etc/cups/cupsd.conf to Allow both localhost and my IP:
Quote:
<Location /admin>
Encryption Required
# Restrict access to the admin pages...
Order allow,deny
Allow From 127.0.0.1
Allow From 172.20.4.32
2) changing /etc/hosts.allow:
Quote:
#
# hosts.allow This file contains access rules which are used to
# allow or deny connections to network services that
# either use the tcp_wrappers library or that have been
# started through a tcp_wrappers-enabled xinetd.
#
# See 'man 5 hosts_options' and 'man 5 hosts_access'
# for information on rule syntax.
# See 'man tcpd' for information on tcp_wrappers
#
cupsd : 127.0.0.1 : ALLOW
cupsd : 172.20.4.32 : ALLOW
I did try to issue the local IP directly on firefox, both as a user and root (running firefox from a root terminal window). I did allow the local IP on the hosts.allow file (on a box above)
I also checked port 631 on localhost:

Now I tried to remove the network cable from my computer and issue 127.0.0.1:631 , and the message "loading..." just stays there without any result. As soon as I connect the cable on the back of the computer, 127.0.0.1 is converted into my local IP and the Network Error message appears!!
Where is 127.0.0.1 converted into my local IP?
Am I right trying to have it running fist without any connection,i.e., 127.0.0.1:631 without cable? I beleive CUPS config is running locally, so it should work, right?
From the error message, I feel like you are behind a proxy, probably a bluecoat. Check your browser setting and remove the proxy setting or add 127.0.0.1 and localhost to the no-proxy list.

YES, I'm behind a proxy. This is a corporate computer from which I have access to the printer when I boot on Win, but not with FC10. Removing the proxy settings on the browser, I have access to CUPS configuration page!!
