Ubuntu Networking :: When Click Configure In Network Tools It Keeps Telling The Interface Does Not Exist?
Feb 12, 2010
I want to use a static ip address on my wireless network but when I click configure in network tools it keeps telling me The interface does not exist and to Check that it is correctly typed and that it is correctly supported by your system
I'm running Ubuntu 11.04 and I've been unable to access any type of Internet service besides web browsing. When I check on Network Tools, it's always set on Loopback Interface, regardless of whether I've just switched it to Ethernet Interface. I haven't been able to download system updates through Update Manager. I'm not very experienced with Ubuntu.
today I tried to configure a network route to a host for testing my network interface. Code: route add 192.168.1.15 eth0 As I have to eth interfaces and both interface got their IP from DHCP (192.168.1.11 and 192.168.1.12) and are in the same subnet, I shut the other interface down:
Code: ifconfig eth1 down Then I tried to test the interface by doing a ping to 192.168.1.15. Problem: When I unplug the cable from eth0 (and eth1 is still plugged) the ping still works. Somehow my linux (it's debian) powers up again eth0 and pings over this port.
How can I stop my linux doing this. I just want to have the route added only on the one interface - not the other. Is it maybe some case of a default-gateway?
i have ubuntu 10.10 and i want to configure my interface eth0 with the commande line with owner (not the Root)$ifconfig : this commande works and listed all interface with some description -> thats goodbut when i use some parametre like @ip and netmask
It was working until a recent update. I have the icon in my system tray. Networkmanager is running. I have tried to reboot the computer and restart the network manager. All switches that could turn the network off is on. Every time I click on the icon in the system tray it tell me the networkmanager is disabled.
I try to configure mouse click interval since a single click is recognized as double click by doing it from KDE mouse configuration in system settings; but my attempt doesn't work even (I set the click interval to 2 sec, but doesn't change anything). What is the best way to do this in slackware?
I used the network manager to configure my eth0 interface.It is working fine. I have found the nameserver entries in /etc/resolv.conf files. But the /etc/network/interfaces file does not carry the ip, netmask, gateway,network and broadcast entries. It only has a entry for the lo interface. where are the settings for eth0 as done by the network manager, stored in case of ubuntu?
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?
Up front: the per browser (or per process, if you will) part is the important part here. I'm well aware of the /etc/hosts(and its Windows counterpart), but would like to avoid this system-global method.
What tools exist to override the IP for a given (i.e. configurable) name per browser? For Firefox there are "Modify Headers" and "Tamper Data". Both of them do not appear to be suitable for my case, because the DNS lookup is done before that. So I can only modify the HTTP headers (e.g. the Host header), but not influence the IP to which it gets sent. But manipulating to what IP it gets sent is exactly what I want to do.
I am using two ethernet interface, in fact one ethernet interface eth0 and other is USB netconenct ppp0. I am using fedora 12 - 32 bit. I can individually use both connections. say if I disconnect ppp0 (wvdialer), everything works fine and same in other case. Now my problem is I want torrent client to use ppp0 and all other applications like firefox and other use eth0. So that I can use both interfaces effectively.
I changed in ktorrent client's configuration, and change interface to ppp0 from all interface, but it didnt work. When my eth0 id down I can ping using ppp0, but when eth0 is also up, I can ping via eth0 but not via ppp0 (ping xxxxx -I interface). What is I am doing wrong? How can I configure torrent client to use ppp0?
My computer says the driver is installed and the device is present. All of that went fine. Now I need to connect my card to my house's wireless network. Am I supposed to do that in System-->Administration-->Network Tools? The problem is that whenever I click on network tools, the application looks like it is going to start-up and then quits/crashes/runs away, whatever. Any ideas on what is causing this?
Okay, I tried launching from the terminal, here is what I got:
I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
Why I am getting this messages and more importantly how do I get rid of them.
Ive been struggling to configure a wireless interface on Fedora 9I need to configure wlan0 command line only with NO display managerIve tried setting up /etc/sysconfig/network-scripts/ifcfg-wlan0 with the right information, doing dhcpbut no ip is retrieved. Checking the dhcp server logs on the DHCP server - no request is received.The link light on the wireless nic is not on either. iwconfig shows it has an Access point associated and an ESSID but im not getting back any IP.There seems to be very little documenta on how to set up wireless nics command line only on Fedora
Been helping a user who recently upgraded to 11.04 as his networking stopped after the upgrade. One thing I noticed was that he could not get ping to work.Then checked my 11.04 machine and it also fails to ping using Network Tools. I know the network is OK as I am using my Ubuntu machine to write this. Ping from the command line is fine so it is only the Network Tools ping test that appears to be broken.
Asked another Ubuntu 11 user to check his machine and he also cannot get ping to work even though his machine appears to be fine. Again this is only using the GUI tool.I know it is not hardware as I can dual boot and in XP everything is fine and I can ping all my systems. Also I am sharing a folder from my Ubuntu and my Mac shares the folder just fine. The Mac can also ping everything except the Ubuntu box. Command line ping works so it is not a basic network problem.So as far as I can tell the Network Tools ping test is not working. Has anyone else seen this or can confirm that it is broke. How do I report this or get it fixed?
I have just installed openSuse 11.4 KDE 64-bit on a Dell M1330. When I click on my networking panel, it says WLAN interface is unavailable. I've followed the steps in the stickied post and found the WLAN hardware info, a screenshot of which is below:Uploaded with ImageShack.usNext it says to do this - you need to look at the logs, in particular the info in /var/log/boot.msg. To see this, you need YaST => Miscellaneous => System Logs and select boot.msg.In YaST there is no such option for system logs under miscellaneous, so I can't do that. The results of the sudo /usr/sbin/iwlist scan command produce the following:
root's password: lo Interface doesn't support scanning. eth0 Interface doesn't support scanning.
How can I install a minimal GUI interface, on a Ubuntu server? And more: Suse has a RUNLEVEL tool, to select application to be launched. What in Ubuntu? I need a GUI interface ONLY to use some useful administration tools, no other application, and need to charge the system as less as possible.
I have a third party program (tightvnc) which I want to monitor and detect if it loses a connection with a client. I don't care if the client has the program open but isn't doing anything with it, I only want to know if the actual TCP connection is lost.
Since TCP takes forever to die on it's own I was thinking the best way to detect if a connection is lost is by bandwidth the bandwidth on the tcp port allocated to the VNC connection. Are there any tools built in to redhat (RHEL 5.2) which I could use to do this? Since I don't have full control of the operating system I would prefer to use built in tools rather then trying to get a new tool installed.
I found lots of pepole who belongs to India and using BSNL Data card wants to connect Internet from fedora so I thought post a thread which will help all how are using BSNL EVDO Data Card. At first click on application - System Tools - Terminal enter the following code on your terminal
Updated part starts here When I was using Fedora 10 I post this thread on that time gedit worked properly with "su" Now here if you are using Fedora 14 and by using su gedit is not appearing then try
Code: su - instaed of only "su" hope gedit will work properly. If dose not work then you can follow the next post instructions. Or you can ask in the forum for I am updating "su" by "su -" If you are using earlier version you can try by only "su" or "su-" if none of this works then follow next post. Just remember you have do this in a single terminal and step by step to avoid maximum uses of "su" or "su -"
I'm having all sorts of problems connecting an access point to my computer, but here is one piece that I hope will get me going, if I can get it solved.My computer has two network interfaces, eth0 and eth1. eth1 connects to the cable modem and thence the world, and works fine. eth0 is supposed to connect to the access point over a private network. Here is the output from route with my IP address blotted out:
