Ubuntu Networking :: OpenDNS - 8.04 Machine Do Not Always Resolve Internet Address

Nov 17, 2010

I have an odd thing going on with DNS. I have two machine's running Ubuntu and for some reason they do not always resolved internet addresses on my Internet connection. This has gone on since the Ubuntu 8.04 when I first started using Ubuntu. Anyway, I use OpenDNS' DNS servers and I have been running perfectly.

This is what is odd. My Windows XP Machine never has the problem. It always resolves. Does Windows Possibly have some Microsoft hosted DNS server hard coded in there as a backup? Things are working fine this way so I am not looking to change. I am just a little puzzled and finally got around to asking, "Why is this".

General :: Fedora 7 Machine Browses Internet On DHCP / But Fails Completely On Static Address

Aug 3, 2010

I am struggling with what might be a minor problem. I have a home computer which I would like to setup as a webserver and hence give it a static IP address. It is connected to by wire to a router that is connected to the WAN via PPPOE. If I enable the network card on DHCP it works fine in browsing the web. If I now set it to static IP address it does not brown. Essentially I use the command setup to run the static IP setup. I then set my IP address to 192.168.254.X , the subnet mask and the default gateway to (this is the router connected to the WAN). I am able to ping the router, however when I try and browse on static it does not work. Your help will be most appreciated as this has taken way too long to solve and I have Googled as much without success.

General :: Networking - Changing MAC Address In A Machine (fedora 8)

Jun 24, 2010

I am doing a test on MAC learning and for that ,I need to change my MAC address of linux machine while the interface is UP. To be more clear, consider eth1 in a fedora core 8 machine. And while the interface is UP. I am running a script which changes the MAC address from 10:1:1:1:1:1 to 50:50:50:50:50:50 (i.e 50 times MAC address is changed) . When I try to change the MAC address when the interface it UP, it gives me the following error :

siocsifhwaddr : device or resource busy

I know the way of changing the MAC address by bringing down the interface but I need to know if this can be done while the interface is UP.

Fedora Networking :: No Internet Connection With Static IP Address?

Feb 17, 2009

I am a windows user with no linux experience prior to Friday. Im setting up a music server (SqueezeCenter) running Fedora 10.

With the help of posts of this site Ive made good progress with complicated stuffnamely getting Samba and VNC working. My Fedora machine and my windows machines now see each others shared files, and I can control my Fedora machine from my windows machine. (The Fedora machine will ultimately be headless.)

But Im having trouble with a seemingly simple issue setting up my Fedora box with a static IP address. With DHCP enabled on my network Ethernet adapter, all works fine. I then used the System>Administration>Network menu to disable DHCP and to assign the same IP address that DHCP chose. When I do this, two cases need to be distinguished:

1. If I keep the box checked for Controlled by Network Manager, the Network Manager Applet reports a network connection, I nevertheless cannot access the internet, but my Fedora machine is able to communicate with my Squeezebox music player (connected to my network via my DSL modem Ethernet connections, and with a fixed IP address). 2. If I uncheck the box Controlled by Network Manger, then the Network Manager Applet reports no network connection and my Fedora machine is not able to communicate with my Squeezebox music player (and I of course have no internet connectivity).

Ive seen references on other posts suggesting that the Network Manager service be disabled. But I see no way to manually configure the network.

How do I decide what IP address to enter in my config file when assigning a static IP. All of the instructions I can find say something like "of course you should modify the file according to your own settings." Should I just use the gateway and IP that returns from "iwconfig" and "route -nee"?

Ubuntu Networking :: Cannot Ping KK Machine, Internet/network ON Machine Works?

Mar 18, 2010

I have an ubuntu kk laptop connected via wireless to my mixed network (xp, win7, other ubuntu), but i can not ping said machine or connect via ssh. Internet and smb-browsing ON this machine work, as does pinging FROM it. If this was a windows machine, I'd say a firewall is in the way, but since it's a vanilla karmic install, this should not be the case (or should it?).

Networking :: Determine The IP Address Of A Machine?

Apr 6, 2009

I'm just an undergrad with duck tape and google searches to hold this place together. Anyways on to my question. Where I work, we have a tape library but no way to configure it, the backup software simply talks to the robot to load and unload tapes. There is a network port on the library and I do have the software, but have been running into problems getting access. I was wondering, is there a way to determine the ip address of this machine by plugging in a cross over cable with a laptop and scanning it? What tools could I use to do this?

Ubuntu Networking :: Cloned MAC Address Only Way To Get Internet Access?

I have a strange problem. I have to clone my MAC address (and specify a different MAC address) to get internet. Without the new MAC address I get an IP address but no internet. This happened with my old (updated from 7.04 -> 10.10) OS installation and with a new, clean install of 11.04. So I have a workaround. But I don't know what the problem is.

Ps. I recently switch modem and router. And I had the problem with old and new modem/router combinations.

Networking :: Ubuntu Machine Gets LAN But No Internet

Sep 12, 2009

A few weeks ago, my Ubuntu machine (Hardy Heron) suddenly stopped connecting to the internet. I usually run it headless, and it was still fine connecting to other machines on my LAN (in either direction), but I can't ping out or run any other 'net stuff. I even tried pinging by IP address instead of name. I did notice that my eth0 (I only have one NIC in the machine) had mysteriously changed to eth1, but I fixed the /etc/networking/interfaces file and the udev rules and now it's back to eth0. Still gets LAN but no internet. I've done ifup/ifdown a few times, even restarted more than once. I could always try another NIC, but I thought I get any hardware suggestions first.
