unable to access gui of cups using ip


Hi, I am unable to access the web interface of cups by ip:
192.168.1.12:631, it says that the connection has timed out.
but when I access the web interface by localhost:
localhost:631, it loads perfectly.
Here is the /etc/cups/cupsd.conf:
Code:

After some trials and errors and several restarting I cannot even start cupsd:
Code:
root:# /etc/rc.d/init.d/cups start
cupsd: Child exited on signal 6!
cups: unable to start scheduler.
Thanks,
Ted

As a starting point, let's get back to where you were in post #1. (Whatever changes you made, roll them back.) If you're not able to get there, then please post the latest messages in your error log.

If/when you're able to get cupsd started again, it would be helpful if you posted output from:
Code:
$ netstat -ltn
Also, what OS/version is this?

I got it working! Sorry for the spam, I guess I am just trying very hard. ALthough the ACL problem still exists, but anyways,
Code:
SystemGroup sys root
should be:
SystemGroup wheel
It's suppose to be a group not a single user, there is the problem. Another problem is opening the port, see the other thread i posted as well.
Thanks for lending me the space though, I hope someone finds these posts useful.
Ted
