CUPS has gone away

UNIX for Advanced & Expert Users

I cannot access CUPS
When I try

http://localhost:631/

I receive

This site can't be reached
localhost refused to connect.

I have purged and reinstalled CUPS and rebooted. It did not help.

Hello Meow613,

I have a few to questions pose in response first:-

  • What have you tried to solve this so far?
  • What output/errors do you get?
  • What OS and version are you using?
  • Is CUPS installed ( rpm -qa | grep -i cups perhaps)
  • Is the cups service started?

Most importantly, What have you tried so far?

There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.

We're all here to learn and getting the relevant information will help us all.

Anyone have any ideas as to how to solve this?

Are there any spurious (unprintable characters) in the cupsd.conf file?

I am not a Linux expert but this:

Message from syslogd@server1 at Sep  9 23:31:35 ...
 cupsd: Unable to read "/etc/cups/cupsd.conf" due to errors.

seems to be quite clearly phrased, no?

If there are not non-printable characters in the file (as Corona688 suggested) and there are no privilege problems (post an output of ls -l /etc/cups/cupsd.conf if unsure) I suppose the file is syntactically wrong (i.e. it has content that makes no sense to CUPS).

Try commenting out everything, then try to stop/start the service again. If it works uncomment one part of the file and stop/start again. Repeat this until you have found the part which prevents CUPS from starting.

I hope this helps.

Can anybody see any non printing characters?

If so, where are they?

Bakunin -

Sorry, I did not see your reply.

Anyway...

root@server1:/home/server1#  ls -l /etc/cups/cupsd.conf
-rw-r----- 1 root lp 6737 Sep 10 00:25 /etc/cups/cupsd.conf

TIA

---------- Post updated at 08:11 PM ---------- Previous update was at 07:04 PM ----------

I have commented out ALL the lines. This is what I get from attempting to run CUPS

This site can�t be reached
localhost refused to connect.
ERR_CONNECTION_REFUSED

I think it is a permission error. Whast is wrong here -

root@server1:/home/server1#  ls -l /etc/cups/cupsd.conf
-rw-r----- 1 root lp 6895 Sep 19 20:04 /etc/cups/cupsd.conf

It probably depends on how CUPS is started, but i suppose it is correct. Try changing that to 644 (rw-r--r--) and restart CUPS for a test - if the error mesage stays the same this is not the problem.

Doesn't it state the reason clearly? "localhost refused to connect": i am not a Linux expert, but as far as i know CUPS opens a network connection to the system it runs on (localhost, or 127.0.0.1) and this obviously fails.

First: now, that the error message has changed it is established that your config file has some error in it. You can and should that correct later. Second: there is also this issue with the refused connection to localhost Possible reasons might be: a host-based firewall rule which prevents this connection, the CUPS process not being allowed to write to /tmp so that it can't create the socket (if i remember correctly it is done it /tmp in Linux).

I can't perhaps tell you all the possible reasons for this in an exhaustive list, but i think you get the gist of it: read the error messages, then try one possible reason after the other and resolve it testwise - if it helps or changes the error, you are one tep further, otherwise step back and repeat.

I hope this helps.

I changed the permissions

root@server1:/home/server1#  ls -l /etc/cups/cupsd.conf
-rwxrwxrwx 1 root lp 6895 Sep 19 20:04 /etc/cups/cupsd.conf

Still doesn't work.

There is no firewall as far as I know.

Hi.

Shot in the dark -- the sources.list.d directory is supposed to contain filenames that end in list . Here's an example from one of our systems (a CentOS box):

$ ls /etc/apt/sources.list.d/
rpmforge-extras.list  rpmforge-testing.list  rpmforge.list

And here is one from MiNT:

$ ls /etc/apt/sources.list.d/
getdeb.list  official-package-repositories.list

However, you apparently have a file name that ends in .d for some reason:

N: Ignoring file 'sources.list.d' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

That would be something to correct, but as I say, a shot in the dark, so it may not amount to anything.

Good luck ... cheers, drl

The solution was simple and direct. I'm sorry I did not realize it and had to burden you with all my questions....

Rename the existing bad configuration file.
Reinstall CUPS from Synaptic.

Works beautifully. Installed HP 1012, which I had not been able to do, with no problems.
