Can't access CUPS

[Neo]

not sure if you are using real cups or cups1311 but for both....cups is a deamon or service and needs to be running

1) what version of cups are you running

cups1311 does not need root powers to use localhost stuff but cups (real) does....I assume you know that?

start it manually or have it run from bootlocal script.

I have a wiki for cups1311 and a manual command would be

Code: [Select]

sudo /etc/init.d/cups start
try changing start to status to see if its running

2) since I have not bothered to read your printer.details...pls confirm is it a usb only device or can you use a different connection?

b) if its usb only....highly recommend to install lsusb as prev mentioned.

then turn on printer and run

Code: [Select]

sudo lsusb
and post the results

Hi AUS9, thank you for your kind help.

I actually have both CUPS installed.

I followed your instructions and below is the output (I've only included the output for the printer).
Please note that I couldn't find lsusb to install but it worked anyway.

tc@box:~$ sudo /etc/init.d/cups start
cups: started scheduler.
tc@box:~$ sudo /etc/init.d/cups status
cups: scheduler is running.
tc@box:~$ sudo lsusb

Bus 002 Device 002: ID 04e8:3419 Samsung Electronics Co., Ltd Composite Device
tc@box:~$

By the way these are the instructions that I tried:

http://wiki.tinycorelinux.com/cups1311

It does not detect any printer and it does ask me for a password and I try to manually add one.

hi

eek

pls don't run both at once....if you can humour me, use apps audit and ensure only cups1311 is onboot (or ondemand) OR the other cups but not both pls

a) it does work with linux as per
http://forums.opensuse.org/archives/sls-archives/archives-suse-linux/archives-hardware-support/372157-samsung-scx-4521f-excellent-support-suse-10-a.html

2) My bad.... lsusb ...I meant
http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/3.x/tcz/usb-utils.tcz.list

but thanks for the output

3) while you try out cups1311 pls also start dbus

so its

start dbus (yes I know gurus claim you should not need it but I get less errors this way) YMMV
start cups
turn on printer
open browser and go to cups page = http://localhost:631

then try to add printer again as per wiki

4) Now I assume that you installed gutenprint if you followed the wiki....but a casual read of samsung stuff suggests you might need to install

http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/3.x/tcz/foomatic-rip.tcz.info

instead

I don't think it hurts to install both gutenprint and foomatic but you have not shown your ppd so here is one that might be of use?

Please note the mention of foomatic in the ppd

What the heck is the path that CUPS on localhost:631 is asking for???

"/usr/local/lib/cups/backend/usb" will tell you what you need to enter - as I understand it, you will not be able to use your printer until this works.

I use a usb printer, but since it is an hp officejet, I have to use the hplip backend rather than the usb backend, i.e.

Code: [Select]

$ /usr/local/lib/cups/backend/hp
direct hp:/usb/OfficeJet_G85?serial=SGG13E0C49VL "HP OfficeJet G85" "HP OfficeJet G85 USB SGG13E0C49VL HPLIP" "MFG:Hewlett-Packa;MDL:OfficeJet G85;CLS:PRINTER;DES:OfficeJet G85;SN:SGG13E0C49VL;"
..so I enter "hp:/usb/OfficeJet_G85?serial=SGG13E0C49VL" as the uri (except that the browser interface finds this automatically).

..you should get something along the lines of (for the usb backend not the hp backend) "usb://samsung/printer_name_blah_blah"

since I have an usb device let me report some things

1) I remove my printer and click on admin ....find new printers

I get the attached image....which correctly detects the name of my printer, ignoring the ppd file that I will use later


2) Only after this device is installed can I successfully run the commands

Code: [Select]

lpstat -p

/usr/local/lib/cups/backend/usb


3) But if Neo  can go to admin...and click on view logs and view error log and post the ouput?

if too large for this site try

I deselected CUPS and left only CUPS 1311.
I am still asked for a password.

I tried using /dev/usb/lp0 for the location.

My printer is not listed, but I did try using a PPD file directly (not 100% sure if it is the correct file and even tried using one of the printers listed).

Here is the output of the error log:

I deselected CUPS and left only CUPS 1311.

What do you mean by "deselected" - if you had both cups extensions (cups + cups1311) loaded, you would need to ensure that one of them is not "onboot", reboot and then check only one of them is loaded.

I am still asked for a password

As mentioned - entering "sudo passwd" in a terminal window will allow you to set the root password.

I tried using /dev/usb/lp0 for the location.

This will not work - it needs to be analogous to "usb://samsung/printer_name_blah_blah"

E [20/Oct/2010:22:31:08 +0000] [CGI] rpcclient not found!

I would guess this is a result of having the cups and cups1311 extensions loaded along with libcups..

Yes, I made sure that only CUPS 1311 is selected in the onboot menu.
CUPS still appears on the left hand side in the Apps Control (sorry I am not in TC right now and forget the correct name of the program where you manage the applications) program, but in in the On Boot side (it isn't in the On Demand side either).

If I need to remove/uninstall CUPS, could you please tell me how to do so.
I am used to using Synaptic or APT and find that TC is very different.

[Juanito]

Perhaps the surest way to check what's loaded is to look for the folders:

/tmp/tcloop/cups
/tmp/tcloop/cups1311

This is where the extensions are loaded - if only the /tmp/tcloop/cups1311 folder is present, then only this one is loaded.

If you only see cups1311 in the onboot section of appsaudit, this should be OK. If you see both cups and cups1311 in /tmp/tcloop, then you need to reboot to get rid of the cups extension and cups1311 will be reloaded "onboot"

hi Neo

Juanito  is the expert here but....can I make it obvious that if you are asked for a root  password.....you have not set up cups1311 correctly.

The whole purpose of me using cups1311 was to avoid setting up a root password to then use with (non-cups1311 or normal cups)

If you prefer normal cups do this pls

Code: [Select]

sudo su
passwd
(enter a new password for root)
(you are likely to enter it twice
then add etc/passwd to your filetool.lst

I will try to get around to a normal cups  wiki  but I plan on updating for alsaconf which now works for me in a different wiki.


2) its the file mentioned in the right hand pane that we care about

so RH list is either cups or cups133 but not both ok?

[gerald_clark]

You will also need to add etc/shadow to .filetool.lst , as that is where the password is actually stored.

thanks for fixing up my bad error.

hi Neo

1)I have changed the wiki slightly so other newbies aren't caught out

cups1311 does not depend on foomatic or gutenprint

2) The ppd file I mentioned and whatever your ppd file is.....will likely need either foomatic-rip or gutenprint so you need to add that package to your onboot or ondemand list
....so that the right hand pane of your cpanel...apps audit.....onboot (or ondemand) shows

cups1311
foomatic-rip
gutenprint

3) Since you have not posted the contents of your ppd I am not sure which package it needs

please re-consider posting it.....in case it asks for a package that TC does not even have?

4) There a number of ways of checking that cups1311 is running

one way is in the wiki or as mentioned by Juanito

please confirm you have it running before attempting to open to the cups page
