Topic: CUPS Addon - Problems accessing the Admin Panel

[keyman0202]

I've installed the CUPS addon months ago and it has been working well.  I applied an update to SME, and now I cannot access the admin panels.  I've unistalled and reinstalled according to the How to, but still no luck accessing the admin panel.

Any advice?

It's rvandenaker-cups that I am using.

Thanks.....

Try to turn you browser's proxy on or off. Any error or description what happens would be helpful. Did you follow the van der Akers description here: http://mirror.contribs.org/smeserver/contribs//rvandenaker/testing/smeserver-cups/documentation/howtos/howto-install-cups.html

Try

Code: [Select]

whereis cups
cups: /etc/cups /usr/lib/cups /usr/share/cups

and check the permissions. Directory owner is root.

Has anyone been able to solve this issue? I think it might have something to do with the  port :361 being shutdown, I have the same Issue

AFAIK cups works on port 631.. was it a typo?

Yes! It is a typo I meant 631.. thank you stefano.

I istalled the cups contrib, which was working fine, until I proceeded to run updates on my SME 7.4 server. Now I cannot access the admin page at  http://myserver:631. I've looked around for more posts but have not seen a solution. I think it might have something to do with the CentOS update or cups rpm upgrade.. but am not sure.. I'm not very well versed in Linux, and appreciate any input..

I don't see cupsd service running.. what's the output of

Code: [Select]

config show cupsd

and of

Code: [Select]

service cupsd status

if the service isn't running, try to start it with

Code: [Select]

service cupsd start

and check /var/log/messages for any error

HTH

Thank you for your help Stefano. It seems its running, I ran the command to start and found no errors in the message log:

Code: [Select]

[root@hpserver log]# config show cupsd
cupsd=service
    LastSync=1251374441
    status=enabled
[root@hpserver log]# service cupsd status
run: /service/cupsd: (pid 4950) 59191s, normally down; run: log: (pid 3588) 59216s
[root@hpserver log]#

Aug 27 13:07:52 hpserver cupsd: Starting cupsd succeeded


I still can't load the :631 port ... Thanks for your help

UPDATE

I notice that when I try to access the http://myserver:631 I see the following note on my command prompt

Code: [Select]

hannel 3: open failed: connect failed:
channel 3: open failed: connect failed:
channel 3: open failed: connect failed:
channel 4: open failed: connect failed:

I am currently SSH into my machine through and using an SSH tunnel as a proxy to run access the server-manager in firefox

I don't know if this helps clarify anything, and again thanks for your help,

David

[Stefano]

if you give

Code: [Select]

elinks http://localhost:631

in console, does it work?

Stefano

[dotcol]

if you give

Code: [Select]

elinks http://localhost:631

in console, does it work?

Stefano

YES!!! that worked, thank you! So it's definitely a matter of settings permision for outside access. Would you happen to know how to modify this through the cups.conf ? Or is some firewall running in SME that I have to modify IP tables? I'm going to attempt to work it out... but appreciate your input.

Again, thanks for all your help

Considering everything works when local on the server:

YES!!! that worked, thank you!

I think it has to do with the tunnel you have setup. I am perfectly able to access the cup page through server manager from a remote systems (since I opened it up through server-manager to the outside world) as well as local machines in the network and from the server itself.
