OpenSUSE :: Firewall Settings For Shared Printer?
Apr 6, 2011
what I need to do to the firewall in order to make a shared printer available to other machines on my network?
I have the printer set up and have tested it with the firewall switched off, but as soon as I restart the firewall, the printer is inaccessible.
I thought that all traffic on the internal network was allowed, but it seems that I need to create an explicit rule in order to get the shared printer working. Unfortunately, I haven't been able to figure out how to do that yet.

Printer is connected via USB to server PC running OpenSUSE 11.1 Client PCs are running 11.1, XP, Vista No problem printing from the Windoze machines
Printing is trouble free with the 11.1 client's firewall disabled, but no printer is available with firewall running.
In hopes of diagnosing the problem I figured I'd open everything I could think of until the printer remained available with the firewall running. Then I planned to start removing exceptions one at a time 'til removing one caused the printer to disappear.
I've gone to Yast>Security and Users>Firewall>Allowed Services>External Zone and tried addingSamba Server
NetBIOS server
Samba Client
Samba Server
VNC
[Code]....

I want to print from my linux box to my win7 pc that has a shared printer. I have cups installed and tried to add pritner using samba, but was unsuccesful, gave me an error when trying to add. The guide i followed is: Yet another Linux to Windows printing tip -- Debian Admin The printer model is a dell 2330d laser printer, it is not in cups, so i added the ppd file i got off the dell support site. I am aware that there is a native suse driver, but i want to print to the windows printer.If possible I would like to know how to do this via command line instead of the GUI.

I have a work desktop plugged into the work network. As I opened my firewall settings I noticed that it is turned off. My question is how should I configure it? I saw that the interface isn't assigned to any zone... I should assign to internal zone and open some port that I need in order to work? There are some guidelines for configuring the firewall?

My USB printer is connected to an OpenSUSE 11.2 desktop on a home network. I shared the printer with samba and can print from a Windows XP notebook connected to the network, but whenever I try to connect a Windows 7 machine, I always get the message that Windows cannot connect to the printer.

how can I make KDE applications to use duplex printing as default? In CUPS, I changed the default settings to "long edge binding". It works in non-KDE Applications like Openoffice, but in e.g. Okular I always have to set it every time I print. I'm using Suse 11.3 with KDE4.

I have two 11.3 systems, one with my printers set up. Is there a basic method to export or transfer my printers' settings and drivers to the other system? Running Gnome on both.

I'm trying to figure out how to change the default settings for my printer under Firefox. I'm mainly interested in changing the default print resolution and the pages-per-side layout setting I can change the settings for all KDE applications through [URL], but I can't seem to be able to find the respective dialog for Firefox / GTK applications.
Firefox itself doesn't seem to have a dialog for the printer default settings; I've looked into about:config but all the value names are rather confusing.
My system environment:
openSUSE 11.3
KDE 4.4.4
Printer: Brother MFC-7420

I suspect this is an initial configuration bug. All firewall logs seem to be going to all
three files. That causes a lot of clutter in the log files, and makes it difficult to see whether there are any serious problems being logged.

I run a small (cabled) network between a desktop with XP with two printers hooked to it and a laptop with Ubuntu 10.04.1 64b. I can approach and use these printers from my laptop and filesharing works also. BUT ... this only works when my Ubuntu firewall (Gufw 10.04.5) is switched off. I am operating behind my router_modem which has a hardware type of firewall switched on at all times so I presume I'm safe. Now my questions:
1. Is this really safe enough?
2. What kind of settings would Gufw need to be able to use it AND use my mini-network for printing? I have no experience whatsoever with firewall rules and settings.

I have tried various rules, like opening port 53 for the DNS with little success. I finally figured that you need to set the source port to 53 and NOT the destination port.However, I have been unable to figure out what ports apt-get requires. The only way I get it to work is to accept everything in iptables.

I have a server with 14 IP's on eth0. I'm using virtual interfaces to handle the IP's, but the iptables don't seem to work on the virtual interface. It blocks ports that I want open. I'm not that great with iptables, I use what I have because it works for me, but as far as tweaking it, I'm pretty lost.
My iptables:

A few months ago a client had me build a small file server running OpenSuse for them. They also had me install an HP Designjet 650C on the server and share it on the network for 2 desktops to print to. All went well and there have been zero problems. They use a few specialty apps that don't have good enough FOSS counterparts, so I couldn't talk them into switching the desktops to Linux, although they were very interested in it. One of the desktops runs Vista and has an XP Pro VM on it (they are considering a Linux VM to go with it so they can dip their toes in the water). There was a locally installed HP OfficeJet 5610 on the machine, but printing from the XP VM was a hassle because they had to tell virtualbox to pass the usb interface to the VM, effectively disabling it in Vista. Then to print in Vista again they had to release the interface back to the host OS. The other desktop (running XP) was also unable to print to it. They asked me to install the 5610 on the server and share it like I did the 650C.
Installing it on the server was easy. I just plugged it in and checked to make sure everything was neat and tidy in YaST. It printed flawlessly. I configured the share identically to the way I shared the 650C. I browsed the network from Vista, found the printer, and installed it using Vista's native driver. Then I sent a print to it from Vista and nothing happened. Vista is very slow to communicate with the printer compared to the 650C, but it will eventually report that the print job was successful. The printer never receives the print, though. Where are the print jobs going? The VM and other desktop are as big of a problem. XP does not natively support the 5610, so I have to download a driver from HP's site. The driver uses a stupid binary installer that will not allow the driver to be manually installed. Running the installer works, but the driver will not install until it sees the printer in a usb port. That won't work because we are connecting to it over a network path. Where can I find a driver that can be manually installed?

So I know Linux has iptables, I'm rather new to linux, and I'm wondering, are the stock settings with Ubuntu/Kubuntu safe? Is there anything I need to do make them more secure? I tried adding rules myself for some things but ended up just not being able to do anything so I had to reset back to stock with iptables -F. Should I be safe running as-is?

I just erased WinXp and installed Ubuntu on old laptop. I intend to use it later ot connect to public Wi-Fi. Do i need to install a firewall GUI and make any special settings? I didn't encrypt home folder during installation. I probably should have done it. But i am already low on system resources (224MB ram, 1.2Ghz CPU). Would that use up any additional resources? Would it make computer run slower? Can i still encrypt the home folder after i installed the system?

Yesterday I installed FC13.i636, Gnome 2.30.0, on my Dell Latitude D505 laptop. Fresh install from live CD, single partition. Installed all 400+ recommended updates last night. System is working *very* smoothly.I want to print (wireless connection) to my Canon MP160 printer, which is attached to my WinXP machine, and is set as a Shared printer in WinXP. I can print to it fine with my iBook.I used the System/Admin/Printing app to set up a networked printer, letting the app "find" the printer. Printer now shows in the app as:
lpd://192.168.1.108
I choose the appropriate driver and tried a test page. Test page job results in queue showing job "processing" but nothing comes from printer, even ten minutes later. Printer properties show:
Printer state: Idle - /usr/lib/cups/backend/lpd failed
How do I fix the "failed" problem?

I have a brand new Canon MF4350d printer/copier/fax/scanner installed and shared on XP that I can't get working on Ubuntu!
XP prints test pages fine. Ubuntu sees the XP shared printer, it sends print jobs, and the XP machine even receives the print jobs (I can see them "spooling" in the XP print manager) but then nothing happens. The job leaves Ubuntu showing 150k but then shows 50 bytes when received in XP before disappearing from the queue.
How I got to where I am...
There was no native driver in Ubuntu for the printer, so I downloaded Canon linux drivers source and compiled (including make install) based on some other threads I've found such as this one.
Compiling left me with PPD files that seem to be specific to the MF4350, although their names show MF4350z not MF4350d. I'm not sure why there were three different files with slightly different names (CNCUPSMF4350ZJ.ppd, CNCUPSMF4350ZK.ppd, and CNCUPSMF4350ZS.ppd).
I added the printer manually using the Ubuntu printer browser setup (Samba) and selected the .PPD files manually. I've tried all three different .PPD files to no avail.
I've toggled bi-directional comm. and tried different print drivers on XP. Nothing's worked yet.

I am having what seems from the forum to be a common problem, getting a shared printer to work. Many similar posts to mine go unanswered for weeks. Can it not be done?I have followed the documentation, 2 computers with 10.4 ...set-up instruction followed ...sharing enabled... cups installed...printer seen by both computers... troubleshooting guide says it can see no reason printing not working, but no dice. This is frustrating to say the least. I have been working at this off and on for a couple of weeks.

I have a Brother HL-2140 connected to a Linux box (Ubuntu 10.04 LTS) that I want to share on a Windows 7 home network (wireless). I followed all the configuration instructions as given on Ubuntu Documentation: Network Printing from WindowsXP. From the Windows 7 box I am able to see the printer in a webpage (using the URL). But when I use the same url in the Add Printer Wizard the system says that it couldn't find the printer.

I'm running Red Hat Linux and CUPS 1.2.4. I can print a test page to a Win 7 shared printer ok. However, when I issue the lpr command from a user or root, it won't print. The CUPS message is "Remote host did not accept data file (1)" and the job just hangs till I cancel it. The only thing I can tell that is different is that when the test page from CUPS is generated, it uses user "guest". When I try to print it using the lpr command, the user is "eddie" or "root". I tried adding a user account named "eddie" to the Win 7 box, I can print successfully from both CUPS and users on several other Win XP boxes.

In my samba configuration, I have a strange share.
Share name: MyPrinter
Shared folder: /var/spool/samba
comment = lp
read only = No
print ok = Yes
The spool directory /var/spool/samba has been shared as a printer. What will be the harm caused by it? (I don't know who shared such). And I also wanted to know the security issue due to it..
