Debian :: Network Manager Shows No Its Connection / What To Do?

May 22, 2011

Fresh install of squeeze gnome, completely updated.

My network connection is working fine, but the Network Manager in the system tray shows "no network connection."

When using the live dvd, and during the install, it showed that it was connected.

Debian :: Network Manager Can't Share Network Connection?

Nov 13, 2015

In Googling around it appears that the Network Manager used to have a nice simple (obvious, logical, straightforward, intuitive, easy-to-use... ... can you tell I'm a bit surprised that there's not a simple button to do this, it's pretty common functionality ) option in the IPv4 tab called "Shared to other computers" allowing you to share your network connection with any computers connected to yours... kind of like this:

[URL] ....

Professor Google seems to indicate that this may have existed in Debian at one point but, I don't see this option anymore. How do I get it back (or is there another gui way to do this without editing the /etc/network/interfaces file... if there's no other way to do this... that's fine but I'd prefer an easy method of enabling and disabling sharing)?

What I'm trying to do... I have a Beaglebone Black connected via IP over USB. When I'm ssh'ed into the BeagleBone, I want to be able to use aptitude install to grab new packages etc... and that kind of requires access to the outside world. Everything I've found so far seems to to require a modification to the interfaces file but since (according to the interfaces man page) the preferred method is to use the network manager if possible... I'm trying to avoid that.

* It should be noted that I'm running sid with the experimental 4.3 kernel so... maybe in doing so I've shot myself in the foot?

Debian :: Network Manager App Showing No Connection

Nov 22, 2010

I was a ubuntu user for 3 years but all that 6 month release and reinstallations and bugs gave my nerves so I decided to turn to the real OS debian and hopefully stick to it. The only problem I have is that although wired internet connection is working the network manager app shows no connection and the wireless is also not working. I have an LG R500 laptop and never had the same issue with ubuntu before.

Networking :: Shows Connection But Not Connected / "connection Information" Shows A Varying Percentage Of Connection?

May 26, 2010

I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).

iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.

OpenSUSE Network :: Network Manager Default Connection Can Handle Virtual Interfaces?

Jun 7, 2011

I've not found how to configure more than one ip address with network manager.Nor with kde nor with plasmoid network manager.I need several virtual ip addresses for eth0 when the "default" of eth0 is connected i.e. "Connected to Auto eth0" should initialize the virtual interfaces.I have not found no even how to configure the ip address.I think this will be used from ifup config in yast or not?There I have the virtual interfaces but they are not taken from network manager.And last but no least: Is it possible that when using network manager the eth0 is enabled even no user has logged in?

OpenSUSE Network :: Configure A Connection With YAST As Well As With Network Manager?

Feb 1, 2010

Im new in this world of linux and suse. I have just installed the opensuse 11.2 in a Dell Inspiron 5160. Such laptop has a BCM4306 Wireless LAN controller. When I tried to configure a wlan connection, I found that the firmware was not installed. After looking in different forums, I installed the firmware b43. Now, my wlan card is abled to find the wireless of my router.

I have tried to configure a connection with YAST as well as with Network Manager, but both cases failled. Specifically, when I use Network manager, Im able to see in the applet my connection, how strong is the signal, but I see a yellow symbol (in one forum, such a box is shown with a green symbol).

I have check many time all about the secutity, encryption, and so one and all seems to be correct. But when I open the mozila firefox or the konqueror browser, no chance to surffer in internet. Now Im just a step to become crazy. The drivers are ok, the information about the router and the keys are ok, but in such a way, I am still harmloss.

Debian :: NetworkManager Applet Shows No Network While Connected - Wired Network Device Not Managed

Oct 30, 2010

I'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says

"Wired Network Device not managed"

While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.

OpenSUSE Network :: Set Connection With Network Manager?

Nov 27, 2010

with the ifup method everything works fine. But now I bought a wireless card, so I prefer to use the network manager to manage my connection. On my computer I need a static IP for wired connection, so I created a new wired connection and I called it "wired connection". But network manager always connect automatically to "Auto eth0" and I can't find how to modify this connection. Setting "wired connection" as default didn't change anything, probably becouse it need me to unlock the default wallet... Now, another problem, I really don't know why network manager applet doesn't appear on system tray, but I'm sure that I'm using it instead of the ifup method.

Networking :: Connection Manager System In Network

Sep 18, 2010

I just wanted to know what's your opinion on my problem.I have few linux servers that can be located on any place in the world, only port 22 is open. At my office I need connection to every server, but every server must be isolated from every server.So by now I worked only with ssh authorization by username and password. What seems to be preferable ?.

1 Going on working with ssh with authorization.
2 working with ssh but with adding keys
3 start to work with vpn

So if I am keeping use ssh with authorization I need something that will change password every month only for security working with ssh key, it seems like key depends on gateway where key created so if change gateway I lost connection using vpn sounds good but in this case I mush isolate servers from each other.The best solution I think is combination of any two methods

Fedora :: Network-manager Looses Connection When 'Allow All Users' Is On

Sep 17, 2010

I have an issue with network-manager. When I edit my wireless settings and enable 'Allow all users' (I have a german locale so I don't know the exact words but I guess it's close enough) the connection drops and doesn't reconnect. If I click on the wlan access point manually (in the nm-applet) it asks for my WPA pass. This is odd since it was already in the wlan settings.

Then when I reset the 'Allow ...' to off, I'm asked for my su passwd and the connection is re-established. Ideally the nm would connect automatically at boot if the AP is available so I'm not happy with the current state...

Fedora Networking :: Connection Sharing With Network Manager

Dec 21, 2010

I'm trying to share internet connection with my wifi capable mobile device. For that I'm creating ad-hoc wifi connection in networkmanager with 'shared to other computers' ipv4 option. And there is the problem - the device cannot get the setting via DHCP. The firewall is adjusted properly by NM, dnsmasq is started. I've looked at dnsmasq arguments string and found that the temporary config file which is provided by NM is empty. So, where else should I look for a possible reason or should I just post a NM bug?

Fedora Networking :: Network Connection Manager Gone / Not Working

May 15, 2011

Fresh install of Fedora 14 from Live cd.Used it for an hour or so, d-loaded some programs, had ti all running great. Wired connection to internet. Had the Network Connection Manager icon in panel. There was an icon saying new updates, alot of them, like 400 or so. Told it to go ahead and up date, left room. Came back hour later was done, said it needed to re boot, so I did. From then on, no internet, not icon, no Network Connection in the drop down list for preferences.

What I have tried:Worked off live cd, again, all works fine, icon, manager, internet all there.In installed version: In terminal, typed service Network Manager, it said unrecognized service.Did yum install network manager. It started to do it, but looked like it was trying to get stuff off mirrors, and of course there is no internet access. error PYCURJ ERROR 6.Of course I can re install, but I figure I will just end up in the same place a few hours from now.

I can use kppp to connect and get the logs I need but I want to connect to the network as soon as I plug it in - Only Network Manager allows this.

CentOS 5 Networking :: Cannot Edit Connection In Network Manager

Jan 12, 2011

I'd like to use NetworkManager on a freshly installed CenntOS 5 on laptop Lenovo ThinkPad T61p. I followed: [URL] Everything went OK, until I selected my active LAN connection in "Edit Connections". After clicking on "Edit", it's not possible to change anything - all is grayed-out. I'm guessing it's a permission problem. But I don't know the internal structure of NetworkManager and what files to look at. I was also expecting that after stopping the network service "Syetem->Admin->Network" would be inactive, but it isn't. Shouldn't the old network manager be uninstalled as well?

Fedora Networking :: Network Manager - Terminating Current Connection

Sep 19, 2009

I have installed recently the Fedora 8 in a computer and during installation it was set a static IP with the netmask and gateway. At first it worked well, but after some boots the connection begins to fail. It seems that the network-manager withdraws the static IP and tries
to get connection via DHCP. Below is the /var/log/messages file during the failed connection:

Code:

Ubuntu Networking :: Connection Sharing With Network Manager And Dnsmasq?

Jan 1, 2010

how to change the IP range provided by default by Network Manager / dnsmasq from 10.42.43.-- to something else?

I have setup a working network using a Bell wireless modem (Canada) and Network Manager in 8.10, 9.04, and 9.10.to do Internet connection sharing. In 8.10 the only way I could get it to work was with WICD and KPPP, many hours spent on this one. I got it to work in 9.04 and 9.10 using network manager, but certainly not out-of-the-box. If someone would like some tips on how I did it, in each case, let me know.

My current challenge is trying to set the dhcp range of dnsmasq (which I am 99% sure is what is handing out addresses) from th 10.42.43.-- address range to a 192.168.0.-- range.

I HAVE edited /etc/dnsmasq.conf and can get the edits to this file to break the setup (dnsmasq will not start) but have not been able to get it to change the IP address range.

It seems that either this file is ignored, or overridden by some other process. I have looked at the very good post at [URL] about dnsmasq but this does not do the trick.

By the way, the way I can get this to work is to start NM, establish my cellular internet connection, then kill dnsmasq then establish my ICS network (on eth0). If I don't kill dnsmasq, then it does bring up the connection, but it then shuts down in a matter of seconds. It is all very manageable using a launcher (kdesudo pkill dnsmasq) on the task bar, but not all that elegant.

the IP range and where this is provided to Network Manager or the network itself is my real question now.
