Could not connect to host localhost (port 631)

fireedo · 12-05-2005, 04:32 PM

this is weird thing.....when I try to add a printer using cups it said that :

Code:

Unable to retrieve the printer list. Error message received from manager:
Connection to CUPS server failed. Check that the CUPS server is correctly installed and running. Error: connection refused.

so I try to do from konqueror with this :
http://localhost:631

but I got error messages too....it said :

Code:

An error occurred while loading http://localhost:631:
Could not connect to host localhost (port 631).

so I try to start cups daemon eventhough I have add or started coz I have already had rc.cups in rc.M....or maybe there is something wrong with rc.cups in my rc.M?

Code:

# Start the print spooling system.  This will usually be LPRng (lpd) or CUPS.
if [ -x /etc/rc.d/rc.cups ]; then
  # Start CUPS:
  /etc/rc.d/rc.cups start
elif [ -x /etc/rc.d/rc.lprng ]; then
  # Start LPRng (lpd):
  . /etc/rc.d/rc.lprng start
fi

so I do it manually with "su" I type "/etc/rc.d/rc.cups start" but it said that :

Code:

root@darkstar:~# /etc/rc.d/rc.cups start
bash: /etc/rc.d/rc.cups: Permission denied
root@darkstar:~#

So what's wrong with my printer?
please anyone help me coz I really need to print some for my job......

thanx in advance

For this part at least, it may be because cups runs as a different user than root. This is a safeguard. You may need to use the "lppasswd" command to enter a user/password before cups allows you to make printer changes. At least this is the way SuSE 9.3 is set up on my computer. I used the cups web interface, but cups wouldn't allow root as a cups administrator, but on the other hand, starting the browser as root (using kdesu) was needed for write access to save the changes.

Found this when browsing, thought it should be here

OK, I finally figured it out! Since cups was running as lp,sys it
didnt have permission to write in the /etc/cups/ directory. I
granted o+w, set the password, and then took away o-w. It was also
a challenge to figure out where cups wanted to write the passwd
file and I didnt find that in documentation

The 'Permission denied' is not related to the permissions of cups
it is related to the permissions of /etc/rc.d/rc.cups which is different

This message normally means that the script is not executable (at least if you have run it as root)

Thanks. Either way, I think it is important to inform people that even though they are logged in as root, cups in SuSE is running as another user named lp who is performing the tasks, and this isn't obvious to anyone who is a newbie like myself.

This is a Slackware forum, not SuSE. Your information is not relevant here.
