Ubuntu Networking :: D-link DPR-1061 Print Server Stopped Working?

Oct 31, 2010

I am using Ubuntu 10.04. In the summer a few months back, I managed to get my ancient HP Laserjet 6L printer working via a wired D-Link-DPR 1061 print server and Netgear network switch. This was even though it was not on the print server's compatibility list. A couple of months later it stopped printing and I have not been able to get it going again since.

The print server has one parallel port (used by the 6L) and a couple of USB ports which I don't use.

I have been going through the Ubuntu add printer wizard. The print server can connect via an IP address. I am using its device URI: lpd://ip address/dlk-portname

I have tried all 5 HP laserjet 6L drivers that come with Ubuntu without success. I have the foomatic/ljet4 [en] currently selected. When I try to print a test page nothing is printed and when I do a print self test I get this message:

CUPS SERVER ERROR There was an error during the CUPS operation: 'client-error-document-format-not-supported'.

By, the way I also have a Windows 7 PC and managed to get the 6L working with same print server using the XP drivers, but every so often it stops working. A reinstall gets it going again.

Ubuntu Networking :: Wireless Stopped Working On 9.10 (Intel WiFi Link 5100)

Mar 10, 2010

I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.

When I boot in Windows, wifi works fine.

Code:
tijl@Smaug:~$ sudo lshw -C network

Ubuntu Networking :: WiFi Link 1000 Series Stopped Working With 2.6.32-32 Kernel Upgrade

May 31, 2011

My Intel Corporation WiFi Link 1000 Series wireless card stopped working yesterday after I did an update via Update Manager.After the upgrade, wireless is disabled and the option to enable it in Network Manager is grayed out. I thought that it might be the new kernel, but changing back to the old kernel I still have the problem.

Networking :: CUPS With Remote Print Server - D-Link DS-802

Dec 6, 2010

I have Rechat FC4 with CUPS 1.45 and a Dlink DS-802 Print Server.

I have installed CUPS, and pointed it at the DS-802,
but no joy.

Windows already prints to the 802 via a W2k3 server, so that works fine. FC4 with CUPS seems to point at the 802 but print jobs from localhost (just go to the print queue, and there they stay.

Windows continues to function fine, but linux wont send to the 802. Also, if Windows users try to print to the CUPS shared printer, it shows "No Accesss".

Fedora Networking :: VNC Server On Desktop 0 On 14 Stopped Working ?

Mar 9, 2011

For more than a year I was happily using my Fedora 11 remotely through VNC over ssh. I was using desktop 0 on port 5900 so people at the office can see what I am doing.

Yesterday I upgraded to Fedora 12, then 13 and then 14. I installed all updates of F14. All went well until I came to use this server from home as usual. The server was not responding.

I brought up /etc/X11/xorg.conf from a backup tape because I discovered that it is there that screen 0 is set and not in /etc/sysconfig/vncservers and rebooted. No success!

At the command lsof | grep LISTEN, I could not see a listener on port 5900

I activated screen 1 on port 5901 and I could log in OK and with lsof I could see listeners for ports 5901 and 6001 but I need screen 0!

During the day I tried many things including removing the vncserver packages with yum and re-installing them, removing the .vnc folder in the user home folder and starting from scratch. The server is still refusing connection!

Fedora Networking :: Ethernet Connection Stopped Working - Cannot Find Server

Jul 23, 2009

After using fedora 11 for a month or two now the ethernet gave out on me tonight. However if I switch to my ubuntu or windows XP install it runs fine. I made no recent changes to network connections, and no installed programs that should effect it.

kernel version: 2.6.29.6-213.fc11
default connection: eth0(and only connection)
ifcfg-eth0:
# Networking Interface
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:1F:C6:DB:05:0C
ONBOOT=yes
TYPE=Ethernet
IPV6INIT=no
USERCTL=no
NM_CONTROLLED=yes
NAME=eth0
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
DNS1=192.168.1.254
PEERDNS=yes
PEERROUTES=yes

I have tried, restarting, older kernel, restarting services, and clearing the DNS Cache. The specific error I get is that "Firefox can't find the server", and most other applications return similar. I can however ping websites still. All other computers on the network are running fine, and booting into another system the internet will work. Just not for fedora.

Ubuntu Networking :: Wireless Suddenly Stopped Working AND Rfkill Command Not Working

Jul 13, 2011

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.

Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.

I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

Ubuntu Networking :: D-Link DBT-122 Bluetooth Adapter Not Working In 11.04?

May 5, 2011

It worked with 10.10, but in 11.04 only partially. It would show up in Bluetooth Manager, and I was able to pair with my phone. But after that it always failed to connect. Tried lots of things before I spent $10 on another nameless Chinese one and that worked fine immediately.

Server :: Passwordless Ssh Stopped Working?

Aug 18, 2011

There are a few threads about this but none seem to me.I have 3 machines setup with a nfs home directory on machine 1.I have created keys using ssh-keygen -t rsa (and left everything blank), then as user on machine 1 run

Code:
cat id_rsa.pub >> authorized_keys2
chmod 644 ~/.ssh/*

this used to work until I upgraded to ubuntu 11.04 (from 9.04), and now it requires a password to ssh. I have tried several times deleting ~/.ssh/* and recreating, to no luck Below is the results when I try to ssh into -2 from -1:

(dumb question, but shouldn't the offered RSA public key be id_rsa.pub rather than id_rsa?)

CentOS 5 :: CUPS Print Server Not Working?

Aug 27, 2010

I just installed CentOS 5.3 on Compaq desktop PC with HP laser jet 2100 attached to parallel port. The PC is connected to LAN with 2 other PCs running Fedora. I configured the HP printer as a shared CUPS printer and I was able to detect the printer from the other PCs running Fedora but I can't print test page from the other PCs.

P.S. I opened up port 513 and 631 for both UDP and TCP on print server PC and cups-lpd service is running on it.

Ubuntu Networking :: Wired Networking Stopped Working

Nov 6, 2010

Wired and wireless networking have been working flawlessly for years on my HP Compaq 6710b laptop. Several weeks ago, after an automatic update via the update manager, my wired network stopped working. I did not notice it directly, since my wireless connection took it over. I only noticed it when I had to work in an office where I didn't know the wireless password.Since then, I have been trying several things and searched several forums. It is hard to find any troubleshooting information about wired networking, as most of the problems seem to occur with wireless.

I did verify that there is no hardware problem. My laptop is dual boot and when I boot the other operating system, the wired network works without problems (as does the wireless.)My Ubuntu version is Ubuntu 10.04.1 LTS. My kernel version is 2.6.32-25-generic i686. I hope anybody can help me getting my wired network working again.

Ubuntu Networking :: D-Link N150 Dwa525 Only Half Working On 10.10

Oct 21, 2010

I've upgraded to Maverick but now I cannot get my wireless card working. In Lucid it didn't work out of the box, but worked perfectly by wrapping the Windows driver with ndiswrapper.

I noticed when I installed Maverick that wireless is enabled in Network-Manager and it gives me the option to create a wireless network or connect to a hidden network but it's not discovering/showing any of the wireless networks in range! So it seems as though the card is being recognized but the driver isn't working fully...? I tried wrapping the windows drivers, but that didn't change the situation at all.

Details of my system:

Code:
Ubuntu 10.10
2.6.35-22-generic x86_64
Code:
Desktop PC:
Intel Core i5 750

Ubuntu :: Server Was Set To Automatically Install Updates, And Stopped Working While Was Away?

Jul 1, 2011

My server was set to automatically install updates, and stopped working while I was away. When I got back to it, it now has a boot menu to choose between kernel versions, with no default or timer. So I pick one, and there are heaps of other problems. the /home partition isn't mounting, despite the fstab being unchanged. I can mount it manually using mount with no problems /var/syslog has nothing since April, and isn't updating when I reboot, so I'm not sure what I can cut and paste to here for you all to look at. The networking isn't running, in fact, most of the network interfaces aren't even showing up.That's just what I've identified so far. I have no idea where to start. I can't find anything wrong other than the fact it's not working.I can't copy and paste any output at this point, because I can't ssh,

Ubuntu Networking :: Wireless Has Stopped Working?

Feb 25, 2010

pulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.

I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?

The USB adaptor I'm using is a Trendnet TEW-424UB

Ubuntu Networking :: Wlan Has Stopped Working?

Jun 30, 2010

I have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.

Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.

Ubuntu Networking :: Sound Stopped Working

Aug 2, 2010

Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).

When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB. Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.What could have occurred, and how might I troubleshoot it?

Ubuntu Networking :: Wireless Stopped Working On 10.04?

Aug 4, 2010

Just recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.

However, this time nothing is working. I've provided some detail and if more information is needed, let me know.

LSPCI:
00:00.0 Host bridge: Intel Corporation Mobile 945GME Express Memory Controller Hub (rev 03)

Ubuntu Networking :: Samba Is Stopped Working

Jun 17, 2011

Been searching for hours and looked at several other threads but still can't figure this out. We have 4 folders being shared from a Ubuntu 10.4.2 LTS Server using Samba. A couple days ago two computers in the office lost access to these shares. The other computers in the office are fine. So far as I know nothing has changed on the server. I can putty into the server still but I can't map a drive or open a window through run (\server_nameetc).

I've also tried disabled iptables on the server and windows firewall on the the windows xp machines. Still no luck. What am I doing wrong? Like I said, so far as I know there have been no changes to the server whatsoever. One day it was working and the next it just stops.

Networking :: VNC To Ubuntu 10.10 Suddenly Stopped Working?

Oct 13, 2010

I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.

Debian Configuration :: Ssh Randomly Stopped Working On Server?

Mar 15, 2010

I'm in somewhat of a sticky situation. ssh has just randomly stopped working on my server after a power failure. Everything else that doesn't rely on ssh is still working fine though. It can still receive mail and everything, just no ssh.Background on the server, running debian etch on a PPC machine.ssh is (supposed to be) running on port 2000. Even if I am physically logged into the machine I can't log in with ssh -p 2000 user@127.0.0.1.
I can ssh to and from any other machine on my network (the server can even ssh into another machine). So it isn't my network causing issues.It seems like the port 2000 is completely closed, if nmap the server's IP address I get PORT    STATE SERVICE

25/tcp  open  smtp
80/tcp  open  http
110/tcp open  pop3
