Ubuntu Networking :: GUI Network Setup And Command Line Not Reflecting Changes?
Mar 6, 2011
I'm running Ubuntu 10.04 LTS, Lucid Lynx and I'm having problems implementing changes to interfaces.I have made changes to my interfaces via the GUI but when I open a terminal window and so a ifconfig I find that nothing has changed. I've opened an editor and looked at etc/network/interfaces but changes made with the GUI never make it to the config file.Does the networking GUI result in changes to the etc/network/interfaces file.

I frequently ssh into machines to do work. In some cases, the machine is headless so there is no option to log in.Under Debian and on older versions of Ubuntu I would pull out the avahi and network-manager packages and manually configure the interfaces file to my liking and be done with it.However, I would now like to learn how to work within avahi/network manager. So, is there a doc somewhere explaining how to work with modern Ubuntu networking at the command-line level? Ie: Setting up a wireless connection, setting static/dynamic IPs, etc?

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?

I am trying to do a command line installation.Finished the installation and my wireless card wasnt working.Did a "sudo ifconfig wlan0 up" and got it working.But for some reason wireless-tools is not installed thus I dont have iwconfig, iwlist, etc.The wireless works and connects fine off a liveUSB.So I am going to give info from this liveUSB run and maybe someone can suggest how I can set the right settings on the Command Line Installation I presume in the etc/network/interfaces.

I just recently installed ubuntu server. I want to be able to install packages and such but can't until I connect to Internet. I tried wifi but couldn't figure out how (I'm a n00b) but now I have ethernet and can't figure out how to make it work. So my question is, how do I connect to my Ethernet with ubuntu server, I could if I had graphical, but I can't get that until I have Internet. I didn't configure network during install, so how do I do it now?

I set up Samba using command line terminal, and my network does not work. I have Samba username and keyring passwords all set, then I go to gui system-config-samba, and my samba user profile password is incorrect. In the past, I have used a 10 letter password, however, every time I boot the computer, I have to go back in and re-enter the password.I wonder if samba is truncating the password because it only accepts an 8 character password? I have deleted the user, and added a new username, and it is still doing it.
If I go into the gui and re-enter the password, usually I can get the network back up with my windows machine. All of the parameters are correct, I use the network to transfer files from my Windows to my Fedora drive all of the time when it works.

I have a CentOS 5.5 server running currently with a Netgear gigabit ethernet card and for wifi I have a wi-fi card with the chipset: RT2860.Now I have gotten the ethernet card and wi-fi card working but my main question is: How do you bridge the connection between the ethernet card and the wi-fi card to create a wireless network with a hidden ESSID if possible and WPA encryption? (So the server basically acts as a wireless router as well as doing all the other stuff I need to do on it).

I am pretty new to C.L.I/text editing work. So maybe its a bit old-fashioned but I am interested in learning how to send email via the command line. I am running 10.04 32 bit
Situation: I have followed the explicit and step-by-step actions at http://klenwell.com/is/UbuntuCommandLineGmail
Question: Upon completion, when trying to send a test email to myself via gmail (from CLI) I get the following error: "msmtp: no recipients found". In CLI below it asks me to explicitly pick a mailx to download. I think I already have mailx as when I type mailx I get "no mail for primary".
Here is my work
Code:
:~$ sudo apt-get install msmtp mailx
[sudo] password for:
Reading package lists... Done
Building dependency tree
Reading state information... Done
msmtp is already the newest version.
Package mailx is a virtual package provided by:
mailutils 1:2.1+dfsg1-4ubuntu1
heirloom-mailx 12.4-1.1
bsd-mailx 8.1.2-0.20090911cvs-2ubuntu1
You should explicitly select one to install.
E: Package mailx has no installation candidate
:~$ gedit ~/.msmtprc
:~$ chmod 600 ~/.msmtprc
:~$ gedit ~/.mailrc
:~$ echo -e "testing email from the command line" > /tmp/test_email
:~$ mailx -s "mailx gmail test" xxxxxxx@gmail.com < /tmp/test_email
msmtp: no recipients found
Here is ~/.msmtprc
Code:
# config options: [URL]#A-user-configuration-file
defaults
logfile /tmp/msmtp.log
# gmail account
#account gmail
auth on
host smtp.gmail.com
port 587
user xxxxxx@gmail.com
password xxxxxx
from xxxxxx@gmail.com
tls on
tls_trust_file /usr/share/ca-certificates/mozilla/Equifax_Secure_CA.crt
# set default account to use (not necessary with single account)
#account default : gmail
and here is ~/.mailrc
Code:
# set smtp for mailx
# gmail account (default)
# $ mailx -s "subject line" -a /path/attachment recipient@email.com < /path/body.txt
set from="xxxxxx@gmail.com (xxxxx)"
set sendmail="/usr/bin/msmtp"
set message-sendmail-extra-arguments="-a gmail"

I'm from a Solaris (printer.conf) background and having trouble setting up a printer on the network. My CentOS box does not have a GUI interface available. I have been playing with lpadmin trying to add a printer - which it did, but everything is disabled, and the "enable" command is not found on my machine.
How do I make a simple printer on my network talk to my centOS box?
Here's the printer.conf from a Solaris machine that works:
raphael:
:bsdaddr=igppps1,raphael,Solaris:
And the printers.conf from the CentOS box:
lumina# more printers.conf
# Printer configuration file for CUPS v1.2.4

I am playing around with the idea of being able to use a cloud or instance based service to install Ubuntu 9.10 Server. This will enable me to have remote access via SSH command line.So far, I've installed Ubuntu 9.10 Server + Ubuntu Desktop to a virtual machine. I can access this via SSH and locally via the desktop. However, in the real environment the only access I am going to have initially is via SSH.
I would like to be able to connect using Windows Remote Desktop or VNC (whichever is easier and most importantly - most secure) to the machine.. even though the desktop is on there, I need to somehow configure the remote access all from the command line.I've had a read of various forums and have been trawling support forums for days but can't find a working solution for 9.10 Server or that fits my situation above where I will not have any physical access to the desktop or machine to configure remote desktop. It all has to be done via SSH/command line.

I wanted to install Debian 8.0 on my second hdd in my UEFI machine, but when I choose UEFI boot from USB, GRUB command line appears, and I cannot boot up the setup. I used Rufus to create the bootable USB stick, using the amd64 kde CD image. I tried several images and I deleted the Linux and Efi partitions from previous installation of Ubuntu . Also I deleted GRUB from the Windows 7 Efi partition.
In the UEFI setup fast boot and secure boot are disabled, and I don't seem to have the option to boot in legacy mode, if I choose the simple USB boot option (without "UEFI" in front) I get "please insert correct boot media, and press any key or reboot". I couldn't manually boot from GRUB command line, because it is showing that all the drives are empty, and if I type "boot" I get "please load the kernel first".

The problem relates only to the configuration of services in text mode ("setup", part of the setuptool package). The setuptool package is "setuptool-1.19.4-2.fc9.x86_64". There is no "Services configuration" menu when I start "setup". The tools listed in the setup window are:
- Authentication configuration
- Firewall configuration
- Keyboard configuration
[code].....
IMHO, the reason I don't have a services configuration tool is the missing services configuration files "98services" and/or 99"services" (or something like that) from the setuptool's configuration directory. (Please correct me if I am wrong.) Can someone please let me know what information should be in those two files, and what are the correct file names? Without them I cannot change the services on this computer. (FYI, the GUI (system-config-services) works, however, I need to run this computer in text mode.)

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 need to add a network path to a configuration file, but I can't figure out how to write the path.
The command dir \computernamesharename works in a Windows command line.
ls //computername/sharename/ does not work under Linux. ("No such file or directory.") ls smb://computername/sharename/ does not work either.
Nautilus shows the location as smb://computername/sharename/, and I can read and write in the shared directory, so it's mounted and I have access.
So how do I get it to work? How do I specify the path so a command line will recognize it?

Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

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.

I run Ubuntu, and it has a nice GUI widget thing that connects me to my home wireless network when I boot. I don't have a problem with that. But suppose I don't start X, and boot to a recovery console for some reason, like I did recently when my graphics were broken after installing Karmic. In that case, my computer won't be connected to the wireless network until I log into X normally. So I can't apt-get anything or anything. It's very annoying. And I don't know how to connect to my wireless network.
I know my wireless network SSID, and I know my WEP key or WPA passphrase. How can I log onto the network with commandline tools? Is there some basic program that I can just run "networkmanager <myssid> <mywepkey>"? I looked at the iwconfig man page and I honestly couldn't figure out how to simply connect to my network. Once I figure out how to connect to the network with command-line tools, where can I put an "autoconnect" script so that it will connect during startup, like it should anyway?
What I don't understand is, why the Ubuntu network manager nm-applet, doesn't just work as a front-end for more basic networking stuff. I don't see any reason why it should require you to start X before working; it could be a daemon that runs at startup, and there could be a config-file somewhere, but it doesn't even start running until I log onto gnome.

I'm trying to connect to a wifi network where it hijacks all requests and redirects you to a page where you have to agree to a terms of use before it lets you connect to the actual outside world. This is a pretty common practice, and usually doesn't pose much of a problem. However, I've got a computer running Ubuntu 9.10 server with no windowing system. How can I use the command line to agree to the terms of use? I don't have internet access on the computer to download packages via apt-get or anything like that. Sure, I can think of any number of workarounds, but I suspect there's an easy way to use wget or curl or something.
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.

I'm thrilled using wicd to connect to wireless networks. But when I suspend my laptop using the special keys, I just want to disconnect from wireless without having to use any kind of GUI or curses user interface. It says in the documentation that wicd works by sending DBUS messages, so presumably it's possible to write a command that talks to the daemon directly.But I can't figure out how.Does anybody know by means of what shell command I can tell the wicd daemon to disconnect me from my wireless network?

Next week we will get a new Server for rent with a preinstalled Debian. If we download the Networkinstaller and put it in Grub, it is possible to set some settings with a script or commandline? We need SSH and the Network haves to run. So we have to set up the Networkadress , Gateway and Netmasq. So if the Networkinstaller is booting that we get direcly access with SSH to install CentOS. It is possible?

The university I go to uses a WPA2 wireless network that requires a netID and password to connect too. I installed wicd but I can't seem to connect to this network, is there a way to add this functionality to wicd, and if so, how do I do that (links to a how-to or guide would be nice, I've yet to find one).
Also, I spend most of my time on campus in the command line, so I'd like to know if there is a way to use command line utilities to connect to this network (again, a guide or how-to would be nice)
I can get online through my fedora live USB just fine (w/ network manager) but I'd rather get on directly from slackware.
