Cannot get CUPS Working!
 

Here are my Nmap results, error message from CUPS and the error that stops CUPS. I have been searching for an answer for several days and I am missing something , but I'm not sure what. I cannot connect to http://localhost:631 to configure printers.

Slackware 9.1 = 2.4.25
CUPS = cups-1.1.20-i486-1

Thanks,

What do /etc/hosts.allow and /etc/hosts.deny
look like? Are you running iptables?

How are you starting cups?


Cheers,

klatu -- I had this problem as well, it turned out that I had inadvertently told CUPS to listen to the same port twice in the configuration file...

In the /etc/cups/cupsd.conf file on my CUPS server, in the Network Options section:

########
######## Network Options
########

#
# Ports/addresses that we listen to. The default port 631 is reserved
# for the Internet Printing Protocol (IPP) and is what we use here.
#
# You can have multiple Port/Listen lines to listen to more than one
# port or address, or to restrict access:
#
# Port 80
# Port 631
# Listen hostname
# Listen hostname:80
# Listen hostname:631
# Listen 1.2.3.4
# Listen 1.2.3.4:631
#
# NOTE: Unfortunately, most web browsers don't support TLS or HTTP Upgrades
# for encryption. If you want to support web-based encryption you'll
# probably need to listen on port 443 (the "https" port...)
#

#Port 80
#Port 443
Port 631

Since I wanted to listen for requests from my laptop, I added the following line:

Listen 192.168.100:631

What I didn't realize was that since "Port 631" was already listed, it was the first to get bound to port 631. When I added the additional one, I started getting the "cupsd: Child exited with status 98!" error. As soon as I removed the line I added, it started up just fine. I guess I needed one or the other, but not both.

Hope that helps.

DOH!!! Can't believe I have spent 2 days on this.

Thanks for the help.

Tino27, that was exaclty the trouble!

Thanks again.
