Debian Configuration :: Network Printers Are Lost Every Now And Then

Oct 3, 2015

Debian Testing, updated daily, running Gnome.

A week ago, a new router was installed at the office and now my system "loses" the networks printers and forces me to manually select them within Cups various times a day to be able to print. The issue was not present when the old router was in place, and all my colleagues can print without problems using their Windows machines.

This only affects printing, for Simple Scan can always communicate with the printers without problems.

The printers are two basic Epson L355 (those with ink tanks) and the "official" driver (from Open Printing) has been working perfectly since I installed Debian. The whole Cups and Avahi stack is installed, and I even added system-config-printer this week to make sure that I was not missing a package.

Because the only variable that changed is the router, there has to be something there messing with my Cups or Avahi configuration.

Note that the new router had a "vanilla" installation, where no advanced settings were touched. All connected devices (computers, mobile phones, printers, etc.) are given new IP address through DHCP every day.

Where should I start? I have already deleted and added the printers within Cups several times during the week, and the problem persists. Is the router renewing the address more often than the old one did? Can this "refresh" be delayed? Should Avahi monitor devices more often?

I guess that I could configure the router and give static IP addresses to the printers, but such a setting was not present in the old router and my computer could locate the printers without problems.

Debian Configuration :: Browsing For Samba Network Printers In KDE?

Mar 12, 2011

I noticed that KDE does not have a way to browse for network printers like Gnome does. I installed system-config-printer to fix this(if there is a KDE route that would be nice as well). Anyway, I go to add a printer and select "Network Printer" and click "Windows Printer via SAMBA". This is where i would typically press "Browse..." but it is unclickable. This leads me to believe that I am missing a package. Essentially my question is: What are the necessary packages to access Windows printers via SAMBA with system-config-printer?

As i did a network restart, i get this error saying :

There is already a pid file /var/run/dhclient.eth0.pid with pid 2802 killed old client process, removed PID file.

Ubuntu :: Autodetection Of Network Printers Makes All Printers Disappear?

Jan 28, 2010

I've been using Kubuntu 9.10 for several months now. For most of that time, I configured and used with no problem several network printers.. a HP LaserJet 3015 at home connected to a Windows machine, and a Xerox Phaser 8560 at my coworking space connected directly to a router.

However, several weeks ago I was at the coworking space, requested a print from my web browser, and in the printer selection dialog, observed the list of printers expanding... some sort of autodetection of network printers was occuring, and multiple instances of the same printer were being offered, with slightly different names. Printing to these devices did not work.

Now, after a reboot, there are NO network printers available no matter what network I'm connected to. When I use the Kubuntu printer configuration tool and try to set up a new printer, it asks me to "Select a connection" to which the only option it gives me is "Other". When I put in an address for the printer it just cycles endlessly, never finding anything.

Debian :: Installing Network Printer - Able To Print To One Of The Network Printers From My Desktop

May 10, 2010

Total Newb here, sorry. I am pseudo-IT at work and have set up a desktop with Debian 5 (accidentally overwrote Windows in the process, but there you go). We are set up with network printers here (all Windows), and I was wondering how to go about being able to print to one of the network printers from my Linux desktop. Can I even connect to the Windows network with this desktop (it is hooked up)? Understand, I do NOT want to screw up anything on the network - they won't let me play anymore if I do. If I download the Linux driver, what do I do next?

Debian Hardware :: Unable To Set Up CUPS / HPLIP And Network Printers

Jan 12, 2012

I'm having a devil of a time trying to set up printing with 3 network printers: an HP Laserjet P4014n, an HP Laserjet 5200tn, and an HP Officejet Pro 8500 a909a. The three printers are connected directly to the office intranet and have their own ip addresses. The system I'm trying to configure is running Wheezy, and HPLIP and Cups are both installed. I have confirmed (from [URL] ....) that all printers are supported.

First, running "hp-setup -i" (hplip-gui is not installed -- I do not wish to pull in half of KDE simply to configure printing), the program only finds the 2 laserjets. Adding one of them creates a printer in CUPS with an "hp:/net/<printer name>" connection. Attempting to printing a test page through CUPS fails with message "/usr/lib/cups/backend/hp failed".

Interestingly enough, running "hp-probe -bnet" finds all three printers. However, running "hp-makeuri" with each printer's ip address fails with "error: Device not found". Hmmm, so HPLIP can apparently go from seeing everything to seeing nothing. Very useful.

Moving to the CUPs browser interface, clicking "Find New Printers" under the "Administration" tab also only shows the 2 laserjets, although each is listed three times(!). The only difference that I can see among the three versions of each printer is in the connection uri:

dnssd://<printer name>._printer._tcp.local/
dnssd://<printer name>._pdl-datastream._tcp.local/
dnssd://<printer name>._ipp._tcp.local/

Adding any one of them seems to work, although I do not understand why there are three of them (presumably different protocols, though what they are and the differences between them are, I don't know).

Logging into the officejet control panel and browsing at its network configuration, I see mDNS, SNMP, and WINS are disabled, although SLP is enabled. Looking in '/etc/cups/cupsd.conf', I see 'BrowseLocalProtocols' is set to only CUPS and DNSSD, so I add SLP and restart CUPS. No change; the officejet still doesn't show. I go back into the officejet control panel and enable mDNS (which, if I understand correctly, is essentially the same as DNSSD). Nothing; the officejet still doesn't show.

Debian Configuration :: Wacom Bamboo CTH-460 Lost ?

Jan 15, 2010

I recently purchased a Wacom Bamboo CTH-460 and have had endless frustration trying to get it to work.

I started by getting the latest stable source from the Linux Wacom project and trying to compile the drivers and kernel modules from source and installing them, though nothing ever seemed to work. If I do lsmod it shows that the wacom kernel module is loaded but when I do more /proc/bus/usb/devices I end up with this:

And no matter what I try it always says Driver=(none). So that means none of the /dev/input events are getting any data from the tablet, which means there's no way for it to do anything with X. So that is the step I am stuck at.

After some time I came to suspect that perhaps the CTH-460 is too new to be supported, and am now trying to compile drivers from the lastest development source realeased on 12-30-09. It said there was support for 5 new Bamboo tablets. However when I try to make the driver I run into this error:

I'm not sure if that is just an error in the make script or not, and if it is, why no one else has said anything about it.

Maybe I'm going about this all wrong, do I even need a new kernel driver for my tablet model? Do I only need an Xorg driver? What modules and drivers need to be in place before I should at least get the tablet tied to an input event?

Debian Configuration :: Uupdate Lost Raids?

Feb 14, 2010

I have recently installed debian on to a system that I built as a media server. It has 4 1TB HDDs in the machine and each drive was partitions as follows:
10 MB /boot -md0
1 GB swap -md1
remaining / -md2

I had the /boot running as a raid 1 so i could make backups and the swap was running raid 0 for 4 GB of swap striped. The rest was all setup as a raid 5.I setup the system using mdadm and all worked out perfect. The system worked fine on reboot and all the raids showed no degration on them. However when the debian update icon came up on the screen came up I opened it and it said I needed some updates which was fine. So it did the updates to my system. system was still fine.

Debian Configuration :: Lost IPV4 After Removing Sendmail Base

Dec 28, 2015

Had an issue on one of my Debian stable servers the other day. After doing apt-get upgrade I was prompted to do autotoremove.

It wanted to autotremove

Code: Select allStart-Date: 2015-12-21  16:25:05
Commandline: apt-get autoremove
Remove: sendmail-cf:amd64 (8.14.4-8), exim4-config:amd64 (4.84-8), sendmail-base:amd64 (8.14.4-8)
End-Date: 2015-12-21  16:25:07

After doing this I rebooted my server (a few days later). After rebooting I had no ipv4. I tried statically assigning IP addresses to no avail. Ran ifconfig eth0 down/up which got me nowhere. Eventually decided to ask "Okay, what changed". Started installing packages that were autoremoved. Had to install from the apt cache using dpkg. First one I tried was sendmail-base. Then did ifconfig eth0 down/up, which gave me networking back.

I have checked the dependencies for sendmail-base and I see nothing that would relate to networking, so I'm really confused on why this happened. I had backups of the server so I went a week back and noticed sendmail-base was installed at that time. So I went a day back, where sendmail-base wasn't installed, and installed it. Sure enough it brought back networking. I'm just stating this because it is more proof that sendmail-base was the missing component.

Ubuntu :: Printers Do Not Save In 'Shared Printers' Group?

Oct 9, 2010

I have a shared printer on my Ubuntu 10.04 machine, and it cannot be seen by other computers (macbook, pc) on the network. I have the printer shared, but it is not a member of the 'Shared Printers' group. When I add it to the 'Shared Printers' group, it stays there until I close the 'Printing' application GUI. Then, when I re-open 'Printing,' it is no longer in that group. I think this is why I can't see it on the network, due to the wording of the option in Server Settings to 'Publish shared printers connected to this system.'

Fedora :: Printing From The Network Printers?

Sep 1, 2011

I am using Fedora 12. I am connected by Wi-Fi to a large network with dozens of printers (the network is running CUPS). How can I set up my fedora box to "see" those printers so that "print..." file menu option works? Also, I know the address of the CUPS server; when I go to System->Administration->Printing and I go to Server->Connect I can connect successfully and I can see all the many printers on the network. But I haven't figured out how to print from my favourite programs yet.

Ubuntu Networking :: Kubuntu Can't Set Up Any Network Printers

Feb 15, 2010

I've had Kubuntu 9.10 32-bit running on my laptop since it came out, but in the past month all its networked printers have disappeared from the configuration, and I can't set up any more. I've been through the forums again and again and cannot fix it. I've installed and reinstalled lots of packages related to CUPS but it doesn't seem to make a difference.I'm not sure what has happened, but I have lots of clues. Since I'm reaching the limit of my know-how here, I'll just list all the clues.

I'm pretty sure the problem is in my Kubuntu laptop, because in my SOHO setup I also have a Kubuntu 9.10 desktop (this time 64 bit) connected to a printer, and I have successfully printed through that from both a Windows XP laptop and a Xubuntu 9.10 box.On the Xubuntu 9.10 box, I just asked for the GUI print configurator and it automatically detected the network printer. No muss no fuss.But on the Kubuntu laptop, when I go into the print configurator, here's what happens:

- it shows two options, "new printer" and "server settings" (image a.png)
- entering "server settings" everything is greyed out and unchangeable (image b.png)
- entering "new printer" shows only one option for a connection, "other" (image c.png)
- after entering the address of a printer i know works (image d.png) the configurator has detected the printer (image e.png)
- but then attempting to move forward it crashes with no explanation.

Running the non-kubuntu version of the configurator GUI provides a bit more information before it fails. When I try to access the desktop with the printer attached it wants a username and password. (which wasn't necessary for the two client machines who successfully printed.) And at the end of the process there is an error: "there was an error during the CUPS operation: client-error-forbidden".

Two more clues:
- when I try to go with my browser to localhost:631 the browser can't establish a connection
- but I can see the cups page on the printer's host machine at 192.168.0.104:631 no problem.

Ubuntu Networking :: Any Ink Level App For Network Printers?

Is there an ink level app that works with network printers? I am currently using Ubuntu Lucid x64 with a Canon MX860 printer that was installed using this tutorial: [URL]. Everything seems to work fine (it prints) but I cannot get any of the ink level apps to work (Mtink or Inkblot). After doing some research, my conclusion is those apps only work with USB connected printers. Is that true?

Hardware :: Network Printing 1 Ubuntu 10.04 And One Os X, 2 Printers?

Sep 18, 2010

I'm a newbie on lucid lynx 10.04

The Hardware:
Mac Mini late 2009 running 10.6.4 (Snow Leopard/OS X)
Dell Dimension 2400 running Ubuntu 10.04 Lucid Lynx
HP Photosmart C4680 multifunction printer/scanner/copier
Canon PIXMA MX310 multifunction printer/scanner/copier/fax
Netgear Wireles-N 150 router model WNR 1000v2

[Code]...

As the HP Photosmart printer is currently connected, it is visible over the network by the macintosh however will not print (all jobs appear in the macintosh's queue without a "hold" designation, printer not on pause. pause/resume only changes the tag on the printer but does nothing to cause the queue to begin printing). Although I can navigate within the printer setup to the existing printer on the network, I cannot connect the printer on the mac without finding a new "printer" instance on the Ubuntu machine when I get there. The printer instance which works is the one the Ubuntu machine created, and the printer instance which does not work is the one generated by the mac, which doesn't work either from the mac or when printed to from the Ubuntu machine, now that this instance exists there.

With the printer connected to the mac, it is visible over the network to the ubuntu box however asks for authentication for the print queue and will not accept any password established for either machine. It also does not specify what account name the password should match with so is an utter quandary.

lastly, I did run dmesg but the result was too large for my terminal's log and scrolling back through it I did not find a section relevant to the HP (or Canon) printer to post here.

Debian Configuration :: Network Not Work When Use 2 Network Cards

Oct 24, 2010

I'm planning to use Debian as the OS for a firewall machine, which will sit between my internet connection and the rest of my computers. Now my network is all wired, no wireless whatsoever. I'm using the onboard the motherboards cat5 socket which seems to be using the VIA rhine driver and I'm also using a 3com 100MBps card.

I can list the machine spec if you want but it's nothing special, an old Athlon 64 rig with 1gb ram and an OEM motherboard, it all seems to work ok apart from the internet doesn't' seem to work. Lenny seems to detect both cards ok and I even used the net install CD and it managed to download everything using the 3com card.

The strange thing is when I'm in Lenny, I can't seem to connect. I can ping google, but when I try and view a webpage, the browser just sits there with a while screen... Could it be that using 2 network cards is confusing Debian? Right now I've only got the modem hooked up the the 3com card, and nothing connected to the onboard network card.

Ubuntu Networking :: Adding Network Printers To Server 9.10?

I have Ubuntu Server 9.10 up and running as my file server. However, it sits amongst other PCs running XP Pro and Network Printers (e.g. Xerox Docuprint C2535A) on the network. My question is whether there is a way of adding the Xerox printer to the Ubuntu Server so that other PCs will send print jobs through the server. I think the printer is windows-based printer. Is it possible to do this? or are there any other options that you may be able to share with me?
