Fedora Networking :: Network Connection Not Automatically Activated
Mar 11, 2009
After an update this week I noticed some strange things with the network.
1. The network connection doesn't activate itself automaticaly. Have to do it every time when booted up.
2. At the taskbar icon the previously "Auto eth0" changed to "System eth0". I guess this is kind of connected to the first issue
3. I can't connect anymore to the windows network -Times out (also worked fine before)
How to set it up to the "old" way?
A friend of mine is running Ubuntu. He used to run Windows XP, but he kept destroying it completely, and I soon got tired of fixing it for him. So I setup Ubuntu, and we're both happier people for it.BUT! The other day he asked me to setup a VPN (PPTP) connection to his workplace, which I promptly did. It also just works, except for one minor problem: When he fires up the VPN connection, I lose the ability to connect to his computer over SSH. As soon as he shutdown the VPN connection, I can once again log in over SSH.I use the SSH connection for basic maintenance and for tunneling port 5900 so I can assist him over VNC.
His nic is setup with DHCP. Gateway is 192.168.57.1. Port 22 is NAT'ed to 192.168.57.2, which is the IP his computer is assigned by the router (it's reserved to his MAC address).
When he connect the VPN, a new interface is created with the IP 192.168.1.32. I'm very much _not_ a network expert. I can manage the very basic stuff, but beyond that I'm quite lost.
I bought Sony vivo c series laptop and I tried to install ubuntu 10.10 version on it.After installed ubuntu the ethernet device was not activated. But It's working fine with wireless network. Similar problem I faced with older version 10.04 also.
Then, I tried with newer version 11.04. It detected Ethernet device.After installation over I just rebooted and I have chosen ubuntu OS, then it stuck and goes to blank screen.I am doing all my work in ubuntu only, i am struggling to recover form this problem for a long time.

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)
But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)
The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.
Is there a way to have both of these pieces of functionality?
I have fc9 installed on my system and I am facing a weird problem When I login to my machine (both as ROOT and USER) I do not get connected to the Internet automatically. I have to right click on the n/w Icon on the task bar, disable it and enable it gain then I get connected.
I just upgraded to Fedora 13 (from 10, using preupgrade), and I've gotten most things working again, but I'm still having trouble with the network.My wired connection (eth0) doesn't connect on boot (even though ONBOOT=yes in /usr/sysconfig/network-scripts/ifcfg-eth0).Because of that, I figured I'd just leave eth0 connected manually (with ifup eth0). However, I then found that if I try to connect to a VPN like this, the system reverts to the "stalling every time I try to connect to the internet" problem that I had earlier.
I'm new to Fedora and have a problem with the network manager. Everytime I start Fedora, it does not automatically connect to the default WIFI Browsed Google and just found [URL]..
Everything was working fine when my laptop got shut down after a battery failure. Now, on restarting, the computer hangs at the login screen. If I close the lid and reopen it, the keyboard seems to work and I can enter password and login, but the touchpad doesn't work at all and all the functions that were to be performed while holding the function key seems to happen automatically (For eg. when I press 0, another key gets typed). Perhaps the drivers are't getting loaded properly, I don't know. The same story is there no matter how many times I restart. I am using Ubuntu 9.10 and the laptop is Dell Vostro 1525
I've a desktop running Fedora 10 connected to the Internet via LAN. There's 3 network controllers in the desktop. One integrated to the motherboard and two additional. I would like to connect other computers (two laptops, one running fc9 and the other Window$ XP) to the Internet via the desktop. I googled the question and found out that I need to adjust thing called 'NAT'.
For that purpose I did the following: iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -j SNAT --to-source 192.168.*.* where 192.168.*.* - is desktop' IP address. I want to use 192.168.2.0/24 as a network for laptops. I activated one of devices (eth1), gave it IP address: ifconfig eth1 192.168.2.0/24 and connected f9 laptop to it.
On the laptop I activated eth0 with the same IP. The problem is: it doesn't work. I can't ping anything from the laptop except its own address (192.168.2.0).
I have installed Fedora 14 about 4 days ago. I have set all the networking parameters like dns path, hostname etc. I have also ensured that I select the check-box for "Enable automatically when system starts" for eth0 interface. But weirdly, whenever I boot my system(or restart), I see that the interface eth0 is disabled. I have to manually enter as root and enable it, each time I boot/reboot my system. Why is this happening? Could you please suggest a way so that I have eth0 interface enabled always when I boot up?Also, my domainname also is not boot-persistent. What steps should I take to ensure that the domainname set once persists across reboots?
I'm also new with linux i tried ubuntu and mandriva, and they worked fine out of the box.But I wanted to try Fedora because it looks great to my opinion.After installing it, everything worked fine, so I updated the system, and after the update my internet doesn't connect anymore, but it does see my wlan ssid. but it just keeps on asking my wpa key.... everytime.
I have somehow made 2 internet connections on my fedora 10. one is system default, which doesn't work. so I usually login and select from the top panel to the other working one. how to choose it from a terminal? then I can do it from a remote terminal.
Suddenly, for no reason apparent to me, on initial logon I don' t have an eth0 connection. I click on the Network Manager icon in the tray, and connect that way. But it would be nice if it connected automagically. How do I fix network to connect on 1st logon?
i have no problem with DHCP Internet conection, when i set up to manual and manually imput an IP ADDRESS-NETMASK-GATEWAY y get local red but not Internet. Im i missing something, i cant find a guide for dummies.
I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?
I recently switched from ubuntu to fedora and had a script to mount and umount sshfs when the network changed states. I placed the scripts in /etc/network/if-up.d/ and /etc/network/if-down.d/ and they were run any time the network went up or down. The closest thing I've been able to find is editing the ifup and ifdown scripts in /etc/sysconfig/network-scripting/, but that looks like it would be broken after an update. I'd also rather not use a script with ping because that wouldn't work well when the network goes up and down several times.I've been looking for a while and haven't been able to find a method similar to debian on fedora. Is there something I overlooked?
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?
I initially loaded Fedora 14 onto a Desktop and started to configure it to be a server but as soon as Iso software updates My network connection completely drops.
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.
Wifi network operated perfectly with f13. Upgrading f13 to f14 did not show any problems except for networking. It seems that the wlan0-link is not ready. Consequently no network information about adresses can be obtained. Tried with network tools to activate wlan0. No reaction Tried to deactivate Networkmanager and bring network up with
service NetworkManager stop ifconfig -a Then ifconfig wlan0 up dhclient wlan0
No reaction on network. The NetworkManager icon disappears which is understandable.
I've installed F10 on my laptop since few days and I'm facing an annoying networking issue: the network connection seems to work well when, suddently, it goes down for a while, and then come back.This happens with both wired and wireless (Intel PRO/ Wireless 3945ABG) connection.
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: Sep 19 10:36:53 canario avahi-daemon[1695]: Interface eth0.IPv4 no longer relevant for mDNS.

I have updated the system this morning and the vpn stopped working!It gives me an error: invalid secrets.I use network manager to connect to a pptp vpn connection, I use fedora 12.Does anyone know the problem?
everything was excellent till yesterday evening but from the evening, when i switched on my pc, the Network Connections icon is missing from the panel of my fedora 12 os. i'm being able to connect to internet from Systems->Preferences->Network connections & check Connect Automatically to my Mobile broadband connection. but i'm not being able to disconnect it. i've to remove the mobile phone from my pc.please put some light on how will I be able to disconnect it (without removing the phone)?
Just replaced a working install of Ubuntu because i like GS over unity but i cant get my USB760 EVDO card to work. The usual fix of editing the cd.rules file and copying some information into modem.fdi does not seem to work on F15..
Also, noticed that when i attempt to create a broadband connection using network manager it allows me to go through all of the setup dialogs, but never actually adds the broadband connection.
I was on my wireless network when I accidently switched on "airplane mode". Several reboots later and I can't get back onto my network. It keeps prompting for a password, even though it's the correct password. I've booted into Mac OSX & Windows on the same laptop and they connect no problems.
How can I delete the network connection to take it from the top again ? You used to be able to right click on the network connection in F14, select "edit connections" and then delete anything that was offending. That seems to have been removed now though ? Where is it stored and where can I kill it ?
I changed the network setting and caused a problem of wireless network. After I completely reinstall the OS of Fedora 13, the wireless network is still incorrect for connection to router.
I have 2 workstations that I'm trying to network together so that I can backup each to the other. One is XP sp2 and the other Fedora 9. Since installing Samba on the Fedora box and trying to get it configured, I have a problem that Add/remove programs won't do installs because it says there's no connection to a network. Network Manager says there aren't any connections, but it worked before the Samba install. Mozilla and Thunderbird can access the internet OK. Both workstations are connected by cable to my router and thus to my ISP (DNS server).
Two questions:- where can I find hints on setting up a wired connection (which card's MAC address does it want? router or wrkstn?) and Am I right that Add/remove is stuffed because of Network Manager?I now have Samba working from Linux to XP, but still can't get into Linux from XP. I tried the Linux PC's MAC address and set up a wired connection in Network Manager. NM still thinks there isn't one...
I recently installed fedora 15 on my computer but I have a huge problem. I can connect to my router wirelessly for a couple of minutes only. Afterwards my computer has no Internet connection although the network manager and the icon on the upper bar says that i am still connected. I tried editing the /etc/rc.local and /etc/resolv.conf as mentioned in other posts in here bit no luck so far.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
