Ubuntu Networking :: Connect To Internet Using Command Line
Jun 6, 2011
I want to connect to the internet using the command line. I'm 95% I have my wireless card installed correctly, since I'm using it right now.dhclient takes a minute or two, then finishes. It gives no output, success or failure. Then I open up Firefox and I'm not connected to the internet. What can I do to figure out what the problem is?
I'm trying to connect to a AP by command line but I can't yet. Using the network manager it's possible but I need the command lines to use in my code programming.
Here it's what I tryed: Code: sudo iwconfig wlan0 mode managed channel 6 key restricted s:'12345' essid 'cassiano-PC_AP' and the tail: sudo tail -f /var/log/syslog Code: Aug 13 14:05:55 cassiano-linux kernel: [13476.935795] wlan0: direct probe to AP 00:15:af:84:29:d3 (try 1) Aug 13 14:05:55 cassiano-linux kernel: [13476.935943] wlan0: deauthenticating from 00:15:af:84:29:d3 by local choice (reason=3)
i cant connect to adsl with pon dsl-provider or any command line. just network manager applet GUI works for me. i follow this guide [URL] and try about 3 hours but without success. i edit /etc/network/interfaces following this thread: [URL] but after any alteration in /etc/network/interfaces and restart network my adsl connections are not work at all and also i lost my GUI applet connections too. then i have to back /etc/network/interfaces to its original content and restart my computer to restore my connections
pon dsl-provider error is:
Plugin rp-pppoe.so loaded. RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5
I am fairly familiar with Linux but had never ventured into Wlan settings / options / too much. I have compatible card (aetheros) and when running - iwlist wlan0 scanning - I get plenty networks showing up - meaning the card works. When I installed distro which is last night (before I ran update), I had that little bars menu at the top of the screen that showed available networks once clicked upon. Since I like to modify and make my settings better - I removed that little AT&T like bar, and now rebooted after update to find that I can not see available networks unless I use iwliset wlan0 scanning.... .#$*&)@&#(&%# - need I say more.
Two questions - how do you connect to the wireless network via command line? What is that vertical bars GUI tool called so I can find it and run it again? Is there (for the love of god) alternative to system-config-network GUI managment tool for wlan?
Then I wait another five seconds, right-click on the networking icon, choose "Enable mobile broadband", then left-click on the networking icon, and choose "Connect to Sprint Connection". I do this multiple times a day, and it's just a bit of a pain, especially when in a hurry. Accordingly, I'd like to script it so I can do the whole thing with a single command.
I've already put the above echo statements into a script and it works great; is there any way to script the actual start of the PPP session itself -- with the caveat that I'd like the networking icon to accurately reflect the latest state?
(In other words, I don't want to bypass the networking icon and just launch the PPP session in the background -- I want it to show that I'm connected, and still let me manage the connection via the icon after connected.)
I just installed a command line version of karmic to an old desktop. During installation, DHCP failed, so I attempted to configure manually (without really knowing what I'm doing) and wound up without a connection. I've been searching for solutions, but really don't understand what I need to do. A million thanks to anyone who can help me get up and running (or at least give me a push in the right direction).I can either connect the computer directly to the cable modem via USB, or directly to my wireless router via ethernet cable. I know what the ip address for my laptop (which is connected wirelessly to the router) but don't know if that would be the same for the desktop or not, and don't really know anything else.
For some reason Ubuntu 8.04 doesn't save my college network settings, so I have to connect manually each time. This is what I physically have to do to connect:
1) Click on network manager icon in the notification area 2) Click "connect to other wireless network" 3) Type in "NETWORK_NAME" into network name area field 4) Select WPA enterprise under wireless security 5) Type in "USERNAME" into username field 6) Type in "PASSWORD" into password field
So what I would like to know: is there any command line equivalent for the above six steps? I would like to write a script which will carry out the above six steps for me automatically, using the parameters NETWORK_NAME, USERNAME and PASSWORD.
I hosed my installation of F14 by installing from some "experimental" repositories. Now I only get XDM at startup and an xterm on login. This would be fine if I could use yum to do some updates, but I have no network connection. I have been over the man page for nmcli dozens of times and none of the options there seems to start anything. I have also tried starting dhclient or using:
ifconfig eth0 up Nothing. So, is there a reliable way I can just connect to the network? This shouldn't be so hard.
ifconfig dsl up ifconfig up dsl ip link set dsl up
But I think I should have typed:
ifconfig ppp0 up
Yesterday I was lost, I updated the drivers for the nvidia card and that broke X, since my internet is not up and running when booted I was wandering how to call it from the command line since that was the only thing I could see.
My GUI for backtrack is not working. I want to connect to internet. I gave the required static ip to my machine. but the problem is I have to give username and pasword through the browser before accessing the internet. Now here , i dont have any browserHow to give the log in credentials through command line in backtrack machine?
is there any way to do a 11.04 Alternate Command Line Install without Internet Connection? I try to install Ubuntu on a Internet-Tablet, wich has no Ethernet-Port and I don't know how to get Wifi to work during Alternate-Install. At previous Ubuntu versions it was possible to let network be unconfigured and install completely from CD or USB-Stick. Isn't this possible in current versions?
Basically, I need a command line solution for sending an HTTP POST request essentially clicking on a button. For future reference, it'd be helpful to know how to send a POST request with, say, a username and password if I ever find myself in that situation in another hotel or airport.
On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.
I tried to install Xubuntu 10.10 Maverick as dual boot on my laptop. However when xubuntu is on, I can't find a way to connect to internet. When I try the 2 arrows on the up-right corner the option for wireless is deemed. I tried offline/online, that did not work either. when I click the firefox It says you are not connected.
I can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.
I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.
However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.
Here are some outputs:
I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?
I've recently set up a local development webserver using Karmic Koala. I downloaded and installed the server version of Kubuntu and have the web server working.
The problem is that for some reason, I'm no longer able to connect to the internet. I can connect to my router, and other machines in my network can VNC into the server.
I'm using an wired connection to the router and have the server set up on an internal IP of 192.168.0.100. I used to be able to connect to the internet, I downloaded and installed a load of packages etc before it stopped working.
The last thing I remember doing before it stopped working was that I installed Samba so I could share files with the other machines on the network (two Macs running Leopard and a WinXP laptop).
I got the share working - I copied a load of files to the server via the share, rebooted, and for some reason now I can't connect to the net (and other machines can't see the Samba share either.) However I can still VNC into the server.
I have installed LUbuntu from a desktop cd-rom in my Toshiba Satellite Pro 4600. There is a Pentium III inside.
I have searched in the forum and found that it is a common problem, but the solutions explained either did not work in my computer or I did not understand them. Maybe together we can fix the problem.
I do not know how to connect to mi wi-fi conection. In the menu of the Network conections, I choose the label "wireless", then click to "add", give a name to the conection, write the ESSID, and the password (WPA) and click "Ok" to save. So my conection appears on the list o Wireless connections.
But now, what should I do? Nothing (as a wi-fi icon) appears on the bar (there is just the cabled connection icon, because I am conected with the ethernet cable). If I click on the cabled connection icon there is no wireless option available.
I have two Roboards that need to communicate with one another. I have sucessfully installed Ubuntu 9.04 using the 386 kernel based on instructions found online.I can use the GUI to set up an Ad-Hoc network using one Roboard ("Create New Wireless Network"), call it Manet, and connect to "Manet" using the GUI on the other Roboard and ping/ssh between the boards. However, when I try to create the same wireless network using the command line using:
ifconfig wlan2 down iwconfig wlan2 key off essid 'Manet' channel 5 ap any ifconfig wlan2 up
I don't see any entry in iwconfig under "Cell". It keeps giving me "Not Associated"When I try to enter the same information on the other Roboard to try to connect to the network, it doesn't connect and under iwconfig, I don't even see any entry for ESSID. Could somebody please tell me why it works when I use the GUI and not the command line.
I have setup my wireless card via ndiswrapper and I can see that if I perform an iwconfig that the card is wlan0. I have attempted to connect with the router but I can't get any connection.I know the password is: ########## (10 digits long) but for the life of me I can't get it to work via command line.
For reasons that are not terribly interesting I decided it would be a great idea to remove and re-install the xserver-xorg package. Which proved to be a much larger mistake than I imagined it would be. I purged the package, and then restarted.Naturally I need to have an internet connection to use apt-get to reinstall xserver-xorg, which is where my idea falls apart.I followed the directions in the How To: Manual Network Configuration. However, after I enter the command "sudo dhclient wlan1" I get the line "wmaster0: unknown hardware address type 801" twice prior to the output that the above link shows. Then I just get DHCPDISCOVER messages until I get a "No DHCPOFFERS received. No working leases in persistent database - sleeping."
I'm connecting with WEP to a router that I know works (because I'm using it to type this on my laptop right now) and I know that the wireless adapter(RTL8187) is installed properly because it automatically connected to my network when I had xserver-xorg still installed.I'm running ubuntu 9.04.I've searched for a few hours and I'm no closer to resolving the issue.
I want to run OpenBox on a netbook. For those of you not familiar, it is a very simple window manager, where I can launch a terminal with a mouse click, and I can start the few apps that I need from the command line. Basically, I am trading eye candy and easy access to a lot of stuff I don't need for a more responsive GUI.
My question is...what package should I install, and what corresponding command line would be used to launch a tool to manage the wireless LAN connection?
I'm running a fresh install of Ubuntu 10.4.1 on a Dell Dimension 4700 desktop.When connected to the network (jack in wall, no router), I normally navigate my intranet and the internet.But here's the issue: this particular Dell machine has an IP addresses that is radically different from all other machines connected to the same network.I have tried to edit etc/network/interfaces to force a different IP, but then I lose connectivity. I need this to follow the IP scheme of my intranet so I can set up a server that resolves by hostname. Is there anything wrong with the NIC or is this something that can be resolved via command line?
When i boot my computer and open ubuntu version 10.04.1 the internet wireless connection i have connected automatically. Now, for one reason i don't know, the internet did not connect to the internet. The progam display a message to uncheck the checkmark in the File Menu. After doing this, i refresh the system but it still not connect.
i have a leased line ( speed 2 MB ) which we use to connect to our mail server , oracle ERP etc.. we have a dhcp scope defined as 192.168.100.1-192.168.101.254. with a default gateway as 192.168.100.90 ( which is a cisco router ) we have a pix firewall ( 192.168.100.10 ).. now the gateway passed all the request to firewall..
we have an ADSL of 4 MB speed.. ip is 83.*.*.230 from ISP. i have a proxy server ( squid ) eth0 is connected to ISP (83.*.*.230).. eth1 to LAN ( 192.168.100.79 ) now the problem is when i put default gateway to eth1 ie 192.168.100.90 the squid connects to internet via leased line.. if i leave the default gateway field empty on eth1 , the squid connects to internet via ADSL ( which i want ) but the problem is no one on the lan cant ping the squid server ( no connectivity to internet for the whole LAN ) how can i solve this problem? i want squid to connect to internet with ADSL, but if i put gateway on eth1 ie LAN squid goes through leased line which i dont want to happen.
I've been familiarizing myself with the command line and am attempting to connect to a wireless network but am getting stuck at the point wherein I need to put in a password.When I run iwconfig I see my card is wlan0.I definitely know my password as I can connect using a GUI. The encryption method for my network is WPA2.Could someone tell me how I could connect to a WPA2 secured network via a command line, and/or where I went wrong with what I've been trying?
I wanted to run a little media server in my house, shared with my laptop only, so I could free up space on my laptop drive. I took one of my Linux boxes out of my render farm and loaded up a minimal install, command line only of Ubuntu Lucid from the mini ISO (32 bit). I had to plug in a lan cable to install, but I wanted to move my box back out to the "farm" that doesn't have wired access to my intranet.
After much research, trial and error, this is what worked for me. My wireless card uses an Atheros AR5001X+ chip, and it works with the desktop cd out of the box. I found the "just works" desktop install uses the ath5k driver that is now included in Lucid, but I'm not using a desktop or window manager. I haven't tried this on server version, if you do, let others know what you had to install to get it to work.
The things I do tell you about, I instruct you as if you are a newbie, however I have left out some things that users should know or be able to lookup easily, like if you want a static address instead of using dhcp. You may not need all of the steps or you may have to do more research and troubleshooting.
Find your wireless card (you may need to lookup what to do if it is not recognized at all)List all pci devices, only show network devices (-v verbose, -vv very verbose): >>lspci -vv | grep Network List all hardware (| less lets you pause at each page - arrow keys, page down/up to navigate, q to quit) >>lshw | less
