Networking :: Ethernet Auto-connect / Auto-sense Doesn't Work
Feb 3, 2011
I have noticed that a common issue to several distros is the fact that the networking subsystem doesn't automatically detect the link if an ethernet connection is disconnected and then re-connected to the NIC after boot. If the ethernet cable is connected after the system is up and running, nothing happens - ethtool eth0 shows link detected: no, and you have to restart the network service to let the NIC know that there is in fact a link, and actually connect. I have a Fedora14 (KDE) box with a brand new Asus motherboard with embedded NIC. Everything works great except the auto-detect of a freshly connected ethernet connection if the link is down to begin with.
Am I missing a ethernet link sentinel utility or something, or is this just the way linux works? I have done plenty of research on plenty of posts, and it seems this is a common problem, with no solution other than manually or programatically restarting the network service in a script to detect the link after a disconnect.
I've recently bought a recycled computer for my office. The plan was to get an old cheap computer and use it to write LaTex documents but nothing else. However, I can't seem to get the thing to connect to the internet. I'm on a University network which has a funny setup but I don't think that's the problem.So here's the deal. I have tried this with 9.04, 10.04 and 10.10 and it hasn't worked. The computer recognizes the ethernet cable. If I issue the command "sudo mii-tool eth0" and get back "eth0: negotiated 100baseTx-FD, link ok". However, click on the networking logo on the top right, and click auto eth0, it tries to connect for about 30 seconds, then gives up. Unfortunately I'm pretty clueless when it comes to networking so I have no idea what to do to try to fix this.
The auto connect feature of NetworkManager Applet (version 0.7.997) isn't working on my system. If the WiFi connection dies, Network Manager doesn't detect that the connection has been lost and try to reestablish the connection. I have to manually click on the WiFi hotspot to reestablish the connection. This appears to be the case both while the computer is running and when I first boot it up (i.e. when booting, if the first attempt at establishing a WiFi connection doesn't succeed, Network Manager doesn't retry or try another hotspot).Is this "normal" behavior for Network Manager? If not, does anyone know a fix? Here's some more info about my system:
I have a Broadcom 4312 wireless chip. I have use the STA drivers that Ubuntu recommends. I can connect quite easily just by clicking on the icon, so this is more than a niggle than a problem.
My network isn't protected as we live in the middle of nowhere (quite literally) and network theft isn't a problem. We also run a self-catering cottage, and let guests have free access to our network anyway, so it is easier for guests to access our network without me having to give them all the key. When I did use wpa, it would start itself up with the laptop, so I kind of know that this might be the cause. Is there any way I can fix it without encrypting the network?
i have wired connection(auto auth) , it was working till yesterday , but now its not working simplicity its not receiving to enter my name and password , its mikrotick hotspot .
I recently installed 32bit maverick and wanted to make it login automatically. I tried enabling auto login from Admin > Login but that didnt work and I was still prompted for my password. Then I went to Users & Groups and changed the password option to Do Not ask for password at login now after I reboot, the user list is shown (only 1 user) and it doesnt ask for password after I click on my username.
However, then it gives a few errors (as i vaguely recall):
1. cannot load .ICE directory in my home directory 2. some error 256 about a gconf-sanity-2 file 3. nautilus cannot load my home directory etc
and then it gets stuck without loading anything (blank wallpaper). i ve tried navigating to my home directory using Alt F2, gksudo nautilus and my home dir contents are encrypted by the ecryptfs (there is a readme.txt file and a shortcut). i have tried to decrypt but it doesnt work... i ve also tried to start/stop gdm, and startx but nothing works. if i stop gdm, then the prompt doesnt recognize my password and keeps on rejecting the commands i enter... I think this has something to do with the home dir not being decrypted due to the dont ask for paswd option... how can i disable the dont ask for pwd without the gui (i can access my / by booting through an external usb).
I press On-button, Debian boots, logs in and automatically connects to the Wireless network AND! to my local pc via LAN. It runs an ssh server, so I can ssh into debian over internet and communicate with the local pc (send a magic packet).Here are my problems:
1) I don't how to log in automatically. This and this doesn't work. 2) I need a network tool that can manage multiple connections and has a reconnect feature. With the default network manager I cannot even connect to more than one network simultaneously although I have two network devices of course.
And I guess I can run all that in console mode, right?
I am unable to connect to the internet at work through the ethernet, previously working. I am not sure of the origin of this problem -- the result of an update or something that I did to the network settings.
In the NetworkManager applet is says Auto Ethernet is connected but I can't ping anything by name or ip address.
The wireless still works without any problem.
I have tried following some of the other threads on similar issues but the fixes proposed on them have not helped to date. And I may have mangled some of the settings files somewhat.
On FC10, when system boots up, it would auto detect (from DHCP) and configure eth0.
This does not happen on FC11, but I can manually configure the interface. The entries in /etc/sysconfig/network-scripts/ifcfg-eth0 are identical on both OS releases.
Don't know if this is related, but when I run System->Administration->Bootloader, it fails system-config-boot - missing module kudzu.
Just noticed that auto connection to my wired ethernet is not being established after restarts I'm making. Never recall this in the past. I do get an auto connect when I shutdown and restart. I'm using 10.04 LTS Lucid Lynx.
Also have noticed that nearly every upgrade over the past week or so is calling for restart to complete the upgrade. Can there be any unwanted problems in doing several upgrades over a period of several days before doing the restart? I'd like to think not.
As you can imagine these two issues together are causing some lost time.
I'm trying to configure an autologin account for a kiosk. I can create the user, no problem. I can set the user to automatically log in, no problem. I can set a delay in the automatic login so that someone is given a chance to log in using their own account, no problem. But if the autologin user logs out, then gdm does not automatically log it back in. This is where I'm stumbling. It seems that for such kiosk uses like this such behaviour would be a bug and not a feature.
I am checking something out in my connection and i just wanted to ask, is there a way to auto-disconnect and connect from the internet, for example say I want to disconnect now and reconnect to the internet in 0.05 seconds, is there any program that does that?
I just downloaded the lastest version of ubuntu to my compaq laptop. I then proceeded to plug in my ethernet cable to establish an internect connection. Under wired connection, it says auto etho1 but, the computer will not connect to it and I have no internet connection.
I just installed the XBMC from the XBMC live CD. I want to configure it in a way to auto-connect to internet. (my router is wpa-password protected.)
i know how to save the password and auto connect to internet from gnome GUI but not how to do it from command line. what should i install, change or configure in order to auto connect to internet? (using command line)
I am running 11.04 and have a netgear USB wireless NIC. When I am logged in I can connect to the wireless network through the USB adapter without any problems.I wish to use the machine as a part time home server and so have installed samba, LAMP etc however when I start the machine the NIC is not activated until I have logged in.
In the past I have done this but only ever over a wired ethernet connection, never wireless? Can some one please point me in the right direction?
I'd like to know how to configure Fedora 14 so my VPN connects and reconnects itself automatically, since the "connect automatically" thing I checked in the network manager doesn't work.Is there a way to make sure that everything uses the VPN, so when for some reason the VPN is disconnected the applications will wait for the VPN to reconnect itself instead of switching to the regular network ?Also since it's pptp VPN I tried to disable Ipv6 but I don't know how to check if I successfully did it, can you guys give me the command line to check that ?
How does one get the wifi to auto connect upon start up, instead of having to manually select it every time i log on? I think the following script is what i need but im not sure where i would even need to install it.Automatic WLAN Picker Script
Upgraded To Ubuntu 10.04 The Other Day. And when I first installed it everything worked great except for my sound card which I fixed. But there was no problem with connecting to my Router via an Ethernet cable. Then I updated the video card drivers, restarted my PC and it wouldn't connect. It would try over around 1-2 mins then tell me its disconnected. No green light activity on the router / network card either.
I've reinstalled fresh copies of Ubuntu a couple of times now, Hoping to get the default settings back. But nothing has worked since.
I looked around the net and found quite a few people had this problem on previous versions of Ubuntu but it would seem most of there fixes were for there Version, so it hasn't helped me.
Heres some info:
ifconfig:
I've tried all the various things from dhclient to ifup/ifdown etc etc.
I've been trying to get and old PCI wireless card to work on Ubuntu 10.04. The card is a Zonet 1602. It was not recognized automatically.
I have been able to get it to work using ndiswrapper except that when the computer is started it does not automatically connect to the network. I can click on the network icon and select my network from a list and it will connect, including properly authenticating the network key.
I have worked through a lot of information on the web but much of it seems to apply to earlier versions of Ubuntu and some if it does not match what I'm seeing in 10.04.
There is a built in Ethernet controller on the mother board but I have disabled it in the BIOS.
Im using a Samsung R420/R470 laptop with Broadcom bluetooth and a Prolink PMO624B mouse.My mouse works when I add it as a new device, but if I off the mouse and on it again, the mouse does not auto connect. I have to press and hold the connection button under the mouse and reconnect to the mouse.The mouse says that it is linux compatible, so I guess its a problem with my bluetooth drivers.
I have installed ubuntu 32 bit version on my HCL netbook. I use reliance netconnect (Huwai EC 1260 or 168c). I have configured it and it works well. But the only problem is that I have to connect the netconnect device before booting. If I connect it when its ON, the networkmanager does not connect automatically. even on the right on the tray icon, enable mobile broadband option is not there.
I have servers in remote locations where I have no control over the network routers or firewalls. I need to have a VPN connection to my servers.Is there a way to create a PPTP VPN connection automatically? I don't want to initiate it, I just want it to phone home, and keep phoning home if the connection is dropped.
I have a nifty new headset (a JawBone icon�the noise cancellation is incredible) and I've successfully connected it to my Karmic laptop (64 bit, for the off chance it makes a difference). The trouble is, I only occasionally want to connect it to my laptop; I mostly use it with my mobile 'phone.
The two devices fight over my new toy a lot, and invariably the laptop wins, contrary to what I want. It seems a pain to have to rediscover the headset every time I want to use VIOP or whatever, so is there a way to add a device to Karmic's Bluetooth list, but not have it connect whenever it sees it?
After so recent updates, I find the network connections has changed.
I see now that it connects to the network (dsl) by default. I unchecked the box 'connect automatically', yet it still is connected by the time the monitor turns on when awakened from sleep or hibernation.
How can I get the auto network connection turned off without physically pulling the plug?
my wired auto ethernet stopped working. It doesn't appear to be my machine or the hub as the connection is fine using windows on the computer.I'm a bit clueless on the Networking front in Ubuntu. I've brought up the Network Connections box and checked that the Mac address is correct (and it is). I've tried it on Lubuntu and Openbox, but still no luck. The only oddity I see is that the Network Connections box says that the auto ethernet connection has never been used .
I code primarily in jQuery/JavaScript, and I'm looking for a text editor for Linux that has auto-indent and auto-outdent (seems to be tough to find that). Any suggestions? I've checked Gedit, Cream, vim, Bluefish.None of them seem to have this feature.
I would like to exec a script whenever a user mount a device. The device could be an internal device (for example a partition on a second hard disk) or a removable one (for example a usb hard disk). The script must have sudo capabilities even if the user is not included in the admin group. Is it possible?
The specific question: I would like to add acl option to a device whenever it is mounted. I tried fstab but it's changing the behaviour of nautilus see:
[URL]... so I would like to create a script with the command
Code: sudo mount -o remount,acl /media/data and auto execute it any time data is mounted.
