Fedora Networking :: Network Manager DHCP

Jul 7, 2009

I have got DHCP issues with Network Manager. Whenever I try to connect using static IP it works, but when I use use Netowork Manager with DHCP, it seems to try to connect and soon says "Network Disconnected"..I've managed to connect to wlan and eth using network, so there shouldn't be any hardware/driver issue.

Ubuntu Networking :: Internet Connection Sharing In Network Manager / No DHCP Server

Oct 14, 2010

How do I tell the shared connection that it has a static IP and that I dont want a DHCP on the network?Do I have to set up DHCP on the box with the shared connection, even if that box only runs DHCP for a single IP address being the eth0 that is shared?Or can I tell the shared connection that it has a static IP and still allow network manager to run the shared connection?Or should I specify static IP's for all clients and the shared network manager and install say firestarter on the gateway to run the NAT for the eth0 out to eth1.

Ubuntu Networking :: Network-Manager "Shared" Method Uses DHCP Range 10.0.0.0?

Aug 30, 2010

I am setting up a gateway Ubuntu box and trying to do this the easiest way possible. Using Network Manager in LL 10.04 I have eth1 (usb) accessing the net and eth0 (wired) set up and working. eth1 has a static IP address of 192.168.0.2 and the USB box has 192.168.1.1. This works and I have no issues with eth0. In order to allow eth1 to "share" the connection I have gone toIPv4 and change the method to "Shared to this computer".

Network-Manager automatically starts a dhcp server and assigns ip's from the 10.x.x.x class of IP's. I want to change the assignable ip range to come from 192.168.1.x. I have figured out that it is set in the dnsmasq-base package as uninstalling this and using:

Quote: >sudo service network-manager restart shuts down the eth0 completely - no IP can be assigned! Reinstall dnsmasq-base and it assigns it back with a 10.42.43.1 IP. (and all other PC's on the network are set to the 10.42.43.x range. Where is the dhcp range set?

Fedora Networking :: No IP Address From DHCP Server On Wireless Network?

Feb 12, 2009

I have installed Fedora 10 on my A860 Dell Vostrol Laptop with AR242X Atheros Wireless card. Wireless card worked out of the box and i could detect wireless network and connect to it. But i have a problem that, my wireless connection is not able to get IP address from the DHCP server. Please help me out what can i do to get this working. I am using WEP security and authentication is open system.

I have windows 7 beta installed on the same machine and on that wireless network works fine so i am sure that there is no problem with the wirless network. I am using DIR-300 router from D-LINK. I tried to see packet log on wireshark and there i see that there is no reply to the DHCP discover message. Actually i don't see any RX packets at all. Which is not normal as there is traffic on the network.

Fedora Networking :: Configuring IPv6 (network) Tunnelling - Getting Only Internal Addresses From DHCP

Aug 25, 2011

I am trying to configure my IPv6 network. My computers are behind a Fedora gateway IPv6-configured, which is working great. But for computers inside my network, it seems I am getting only internal addresses from DHCP. Here is my ifconfig for an internal computer:

Fedora Networking :: Network Connection Intermittent After DHCP Configuration - Stops Working Randomly

Jul 17, 2009

I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.

There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.

Fedora Networking :: Network Manager Has Disappeared

Mar 11, 2009

I updated my FC10 just a day back. The problem is that Netwrok Manager has disappeared. And in spite of re-installing it, it doesn't appear on the panel when i enter 'NetworkManager' as root in the terminal.I have a USB modem right now. Update was made through a broadband connection. Ethernet works perfectly well but this USB modem of mine doesn't work at all. And I have to use USB not Ethernet.

Fedora Networking :: 3G Dongle Doesn't Appear In Network Manager?

Jan 20, 2009

I have run Fedora 9 and 10 on my Dell Inspiron 640m for about 6 months now and generally experience very few issues with it. Specifically I've been running Fedora 10 KDE 64bit since it was launched. Up until I had to reload it a couple of weeks ago my Vodafone Huawei E172 3G dongle worked perfectly with Network Manager. Since the reload the dongle is detected by the OS (lsusb lists it correctly, etc) but nothing I do will make it appear in Network Manager.

I've tried manually configuring a GSM connection then plugging it in, but no joy. I've also tried using it in my Acer Aspire One which runs Fedora 10 XFCE and it work, but when I try it in another Dell Laptop running Fedora 10 KDE 64 bit it doesn't. I'm assuming that a recent update must have caused some issue as it has definitely worked in both Dell laptops in the past. As mentioned I've reloaded recently but the other laptop hasn't been.

I'm unsure where to go from here. I haven't been able to get Vodafone's beta drivers working under F10 (although I did under F9) and can't find any posts on this issue. The version of Network Manager that I'm running is NetworkManager-0.7.0-1.git20090102.fc10.src.rpm, which was released shortly before I reloaded. Chances are I just didn't try my dongle between the update coming out and the reload, so didn't notice the problem before hand.

Fedora Networking :: Network Manager Settings All Grayed Out ?

Mar 10, 2009

I'm running Fedora 10. My Network Manager settings are all grayed out. They are uneditable. I can see the detected settings, but not change them. All of the settings fields are disabled.

Is there a way to enable these, so that they can be edited?

Starting with the menu in the upper left corner of the GNOME screen: System/Preferences/Internet And Network/Network Connections

The Network Manager window appears correctly.

I see all automatically generated settings that were created for my various devices:

In particular, I want to be able to edit "Auto vmnet8", for VMware usage.

I know about the workaround of going back to the manual network configuration as used in older versions of Fedora, such as editing the files in /etc/sysconfig/network-scripts/ifcfg-* and then enabling the old "network" service and disabling the "NetworkManager" service.

However, this workaround really won't work in this situation. The VMware interfaces, vmnet1 and vmnet8, are virtual interfaces that *only* exist when the VMware services are running. The VMware services are started *after* the old manual network configuration would be applied. So, at the time the scripts in /etc/sysconfig/network-scripts are processed, the vmnet1 and vmnet8 devices do not yet exist! I'm hesitant to change the numbering of services, lest other things break (VMware on Fedora 10 is rather fragile already).

I love the feature of NetworkManager to be able to automatically apply settings to newly materialized network devices (such as vmnet1 and vmnet8 when VMware is loaded). However, I need to also be able to edit those settings.

Is there a solution that will make my Network Manager "Edit" window not be entirely grayed out? I can see the settings pages just fine, but unfortunately, they are all disabled and I can't edit them at all.

Fedora Networking :: Network Manager Connects With 'auto Eth 0'

Jun 23, 2009

I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.

Fedora Networking :: Network-Manager PPTP Add Routes

Jan 13, 2010

I currently managed it to get a pptp-connect to my home network. now I have another little problem. NetworkManager always routes the whole network traffic over my home network if i am connected to the home network.If i set the "Use this connection only for resources on its network" I have do manually say:

Code:
route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0
After that only the correct traffic runs over the vpn. Now my question is it possible to setup the route via the networkmanager gui?

I have tried to delete all devices, but there is no user interface from which I can do that. Network Manager does not appear in any system tray. I even did a complete remove and reinstall, to no avail.This is true on both 32 and 64 bit Fedora 12, and on laptops, desktops and VBox VMs.Here is what I see in messages.log:

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.

Fedora Networking :: Does Network Manager In F15 Support Bridging

Aug 24, 2011

does Network Manager in Fedora 15 support bridging and if so, can you configure the bridge using your wireless interface? All of the information I've come across so far said that you can NOT create a bridge using a wireless interface, and that Network Manager doesn't support bridging, but this info was also from Fedora 12 and below, so I don't know if it's still relevant for Fedora 15. I would certainly hope that by now you can make a bridge from a wireless interface. Even the lowly VMware Player offers this option.

Fedora Networking :: Network Manager Disconnects After 2-3 Seconds But It Works / Fix It?

I'm currently on F11, and experienced problems with Network Manager. Whenever I to connect to a network, wired or wireless, it just seems to try to connect, and then after 2-3 seconds, it just reports "Disconnected"..

Then I switched to network, and both wired and wireless works. so I don't think there is any driver or hardware issue...

Does anyone have any idea of this problem? The network manager have worked on the live CD version ( before installed to HD).

Fedora Networking :: Fixing Network Manager / Caching Name Server

Sep 5, 2009

I've set up a caching nameserver on my laptop running Fedora 11. The problem with this is that NetworkManager always overwrites the entry that points to the local nameserver. NetworkManager no longer respects /etc/dhclient.conf or at least its scripts run after dhclient.conf. Also it doesn't respect /etc/sysconfig/ network-scripts/ifcfg-* setting of DNS{1.2}.The man page of NetworkManager describes scripts that run in /etc/NetworkManager/dispatcher.d which can be run when interfaces are brought up and down. I've written a script that will put the entry needed for the local nameserver.

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:

Fedora Networking :: Did Network Manager Kill Eth0 Access

May 6, 2010

I have a troubling networking situation that is compounded by the system being remote without any out-of-band mgmt in place nor a serial connection - but am relying on a coworker entering commands into the terminal for me, or doing stuff in the GUI I have an FC12 i386 install running, that was up and stable for 6 days. Primarily this was only being used for a deployment of nTop. Up through Monday evening, I was connecting to the system (in NY) via VNC (here in SF), and was successfully watching nTop do its thing.

Tuesday morning, I go to connect to SSH and I can't get in. The NAT translation is still in place on the firewall, but there is no connection to the NIC/eth0 from the router. This is what I've had my coworker run:

[code]...

I was going to try and have her run the /sbin/mii-tool eth0 tomorrow a.m. just to verify that the interface isn't physically bad? But this is a brand new desktop, and I can't for the life of me understand why this interface went down. I also have the internal IP on a DHCP reservation, which is the same IP listed in IPADDR in the ifcfg-eth0 file - could this be a problem? should I remove the DHCP reservation? I did this so I could SSH to a public IP which I have NAT'd back to the internal 10.0.x.x address I had my coworker take a look at the GUI, and the eth0 properties are "inactive" and the "Activate|Deactivate" buttons are greyed out.I suppose I can have my coworker grab the /var/log/messages and copy to a USB drive, then email me that from another workstation.
