Howto: Cups Printing in pfSense 2.0

SeanyC · Sep 27, 2012, 7:34 PM

This Tutorial is fantastic and helped me set up CUPS on my system.
However, When I copy and pasted the recommended .conf file, I received syntax errors for line 33 and similar lines.

For some reason what should be 1 line…

… is split into 2 with a blank line in between.


 <limit send-document="" send-uri="" hold-job="" release-job="" restart-job="" purge-jobs="" set-job-attributes="" create-job-subscription="" renew-subscription="" cancel-subscription="" get-notifications="" <br="">Reprocess-Job Cancel-Current-Job Suspend-Current-Job Resume-Job CUPS-Move-Job CUPS-Get-Document></limit>

Once I resolved this, I had no more issues.

Followed these instructions to the letter with pfsense 2.0.1 release. However I cannot access CUPS over HTTPS only HTTP. When I check the CUPS admin error log, it includes this:

E [01/Oct/2012:10:54:06 -0500] Unable to create SSL server key file "/usr/local/etc/cups/ssl/server.key" - No such file or directory

If I manually create the /usr/local/etc/cups/ssl/ folder the error persists even still.

Any assistance would be appreciated. Thank you.

Hi,
I installed cups on pfsense 2.0.1 as described above, but I have always these errors:

If I manually create the directories then cups works well, but when I reboot pfsense I have the same errors.
Any help would be appreciated.
Thank you.

@catfish99:

I couldn't get the repository you mention in your post to work. Seems the URL has changed to the following:

setenv PACKAGESITE http://ftp-archive.freebsd.org/mirror/FreeBSD-Archive/old-releases/i386/8.1-RELEASE/8.1-RELEASE/packages/Latest/

@kevev:

repo:
setenv PACKAGESITE ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/old-releases/i386/8.1-RELEASE/packages/Latest/

I have a nanobsd implementation and can not get this or any other "setenv PACKAGESITE" to work for me. Is there another trick in the Nanobsd world? Picture of my install is also attached…
Many thanks.

Is it possible to use USB printer? My CUPS finds nothing =( printer at

kernel: ugen0.2: <samsung> at usbus0</samsung>

@ncat:

Did you read the instructions given by the cups package after install? It may help.
Read the part about "USB printer" at the bottom. I have not tried this so I do not know if it will work.
Good luck.

To enable printing with local printer you need to give group 'cups'
r/w access to printer device:

1) Add following to /etc/devfs.rules (create if it doesn't exist):

[system=10]
add path 'unlpt*' mode 0660 group cups
add path 'ulpt*' mode 0660 group cups
add path 'lpt*' mode 0660 group cups

2) And following to /etc/rc.conf:

devfs_system_ruleset="system"

3) Restart devfs: /etc/rc.d/devfs restart

If your system supports 'devd' you can copy
$PREFIX/share/examples/cups/lpt-cupsd.conf to $PREFIX/etc/devd/

To enable printing under Gimp and MS-Windows clients do the following:

1) Uncomment application/octet-stream line in mime.types
2) Uncomment application/octet-stream line in mime.convs
3) Restart cupsd

If you are using libusb, it is important that no device driver, e.g.
ulpt(4) is attached to the device you wish to use. In this case please
ensure the cups user and group has read/write access to /dev/ugen*

If you are using a USB printer wtih FreeBSD 8.0 or later, you will
need to find the proper /dev/usb/* device pointed at by the /dev/ugen*
entry. Follow the instructions for devfs.rules as above, but append a
rule similar to the following for a printer attached as /dev/ugen0.2:

add path 'usb/0.2.*' mode 0660 group cups

kevev · Feb 20, 2013, 7:03 PM

If anyone is trying to do an embedded "CF" install on a read only filesystem, here are some steps:

1.) Remount the root filesystem read/write before installing/modifying anything.

mount -urw /

2.) Set the pkg_add temp directory to somewhere that has space.

setenv PKG_TMPDIR /tmp1
setenv TMPDIR /tmp1

Note: If you notice any of the pkg_add commands failing with error "Broken pipe" while installing
dependencies, you will need to install the dependencies manually. I would start with the last
package listed right before the error and install each manually, one at a time.

Update

This will not work with the Prolific Technology Inc. usb-to-parallel adapters as nanobsd does not seem to have the module/s for this chip.
I am not sure about other usb-to-parallel devices.

phreshjive · Apr 11, 2013, 3:55 AM

Running 2.1Beta, followed the instructions. When I try running /usr/local/etc/rc.d/run_cups.sh, it returns Command not found. Also rebooted. Still cannot connect to 631.

Checked the error log (/var/log/cups/error_log) which states: E [10/Apr/2013:22:37:15 -0400] Syntax error on line 33.

Anyone have a clue?

Edit: Solved my own problem… spaces are inserted which need to be deleted in various lines (e.g. 33, 42...). Sorry for bumping the thread)

Edit2: How would one go about upgrading to the latest version of CUPS?

ncat · Sep 15, 2013, 5:46 PM

when trying to add new printer - cups requires authentication. What credentials should I use? root + %system pass% Or %pfsense login% + %system pass% do not work…

@kejianshi:

http://en.wikipedia.org/wiki/Attack_surface

Ok, But still no answer to my question :)
I should have missed something during installation or not?
It seems that the easiest way to buy a print server but he needs a place, one more outlet for additional power adapter and so on.

kejianshi · Sep 15, 2013, 7:40 PM

You have samba on this also? I'm just looking at my CUPs settup and comparing.

(for making system changes, I'd think you would need to use the pfsense root username and password)

ncat · Sep 15, 2013, 9:11 PM

no i have no samba…
and all login-password pairs which come to mind dont fits..

kejianshi · Sep 15, 2013, 9:14 PM

I'm not sure - When I setup CUPs on this system, I don't remember needing to do anything with passwords, but that linux and not BSD. I did need to configure CUPs to allow guest printing via IPP without usernames or pass.

ncat · Sep 15, 2013, 10:27 PM

well, maybe you can help me with another issues?

It seems strange that when i plug printer to usb port i have only one message:

kernel: ugen0.2: <samsung> at usbus0</samsung>

I guess that normally there should be something like this

ugen2.2: <samsung> at usbus2
ulpt0: <samsung 0="" 2="" samsung="" ml-2010,="" class="" 0,="" rev="" 1.10="" 1.00,="" addr=""> on usbus2</samsung></samsung>

my devfs.rules seems to be correct:


[2.0.1-RELEASE][admin@pfsense.ncat.routerpc]/dev(41): ls -l
total 3
<...>
lrwxr-xr-x  1 root  wheel            9 Aug  2 22:51 ugen0.1 -> usb/0.1.0

3)additionally i installed SpliX with pkg_add and now it is also seems to work ok:

/usr/local(17): lpinfo --make-and-model 'Samsung ML-2010' -m
samsung/ml2010.ppd Samsung ML-2010, SpliX V. 2.0.0

/usr/local/share/cups/model(36): ls -l

drwxr-xr-x  2 root  wheel  1024 Sep 15 20:02 samsung
drwxr-xr-x  2 root  wheel   512 Sep 15 20:02 xerox

4)Is lpinfo -v output correct?

/usr/local(18): lpinfo -v
Password for root on localhost?
network http
network ipp
network lpd
network socket

I can't add printer using lpadmin. Maybe smth wrong with the command:

/usr/local(21): lpadmin -E -p net_printer -v file:/dev/usb/0.2.0 -m "samsung/ml2010.ppd Samsung ML-2010, SpliX V. 2.0.0" -L "ML-2015 home router" -E
lpadmin: Unable to connect to server: Bad file descriptor

And i can't add printer using Web interface: http://clip2net.com/s/5L6TRv (sorry for Russian language)

kejianshi · Sep 15, 2013, 10:58 PM

Nope - Never used pfsense with CUPs. I'm not sure what to recommend for you and I'm also not sure if its recommended.

kevev · Sep 19, 2013, 4:27 AM

Your issue with the password may be Chrome browser if you are using it. I just tested and that browser will not allow loading the "Add Printer" screen. Try Firefox or IE.

If you are using a USB-to-LTP adapter like me you should see the device:

[2.0.2-RELEASE][root@router.localdomain]/root(62): ls /dev/|grep lpt
ulpt0
unlpt0

[2.0.2-RELEASE][root@router.localdomain]/root(63): lpinfo -v
Password for root on localhost?
network http
network ipp
network lpd
network socket
direct usb:/dev/ulpt0
direct usb:/dev/unlpt0

Thank you for help. IE also wants login and password.
Opera - same thing.
Could you share your cupsd.conf (/usr/local/etc/cups.cupsd.conf)?

As for interface - I use usb, not usb-to-lpt converter (ls /dev/|grep lpt shows nothing)
Maybe I should specify login and pass for cups group? Or what group? Ooohh… :(

kevev · Sep 27, 2013, 3:22 AM

User is root or admin. Both work. Password should be the same for admin and root unless you changed them.

Found this article for pfSense 2.1: http://www.buildyourown.info/router/cups-printing-pfsense.html
Works perfect on pfSense 2.1 x86 CF
