-su: /etc/init.d/cups: No such file or directory
 

Recently I have installed Slackware, I want to use CUPS but when I try to use http://localhost:631/ I get nothing. And the port 631 is not listed in open ports found by Nmap.
I know that I have CUPS installed.
I tried to start the CUPS service by the following command but I got error:
What's wrong?

Try /etc/init.d/cups status. See if the service is already running. Also some distros call it cupsd.
I don't know the command for chkconfig in Slackware but I would make sure the service is setup to run at boot and try a reboot.

There is no file named "cups" or "cupsd" in "/etc/init.d". Therefore no parameters can be used for any of these files in the "init.d" directory.

Is there any files under /etc/cups? I am not sure if that is where it is installed under Slackware.
do a find for the cupsd.conf see if it installed at all. You will need to be root.
find /etc/ -iname "cupsd.conf" -exec ls -lh {} \;

If there is no cupsd.conf I am guessing the install failed.

Thanks for reply; Yes. The file "/etc/cups/cupsd.conf" is present.
Solved; As Philip sais:
