I am trying to write an app that will perform some actions when a network interface is unplugged. Is there a way to get the OS to signal me when a network interface is unplugged. I have looked at DBus but can't figure it out.

I know how to deal with a mouse click event like so:
Code:
But was happens when I am dealing with mouse dragging? Will my implementation of mouseDragged() get called for every pixel moved? So I just getX() and getY() like with a mouse click?
Also, in order to know when mouse dragging stops and starts, do I also have to put code in mousePressed and mouseReleased?
How to do so? For starters, I'm not sure there is such an event. Maybe it has something to do with the OS moving through certain run-levels

Pianobar has the ability to run a script based on events, I'd like to take advantage of and use perl toparse the artist,song,album and update the corresponding fields. Then later retrieve them and display them with php/html. I am by no means proficient with perl. I started to use bash, but it looks like perl will be much more efficient and and less time consuming.

I found multiple sites explaining how to add IPs to a network interface as virtual interface like eth0:0. However I can add IPs to an interface as well using the ip command: ip a a 192.168.2.2/24 dev eth0 What I want to know is how I can make this persistent on rhel/centos.
View 2 Replies View RelatedI am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
[87.186415] Stack:
Why I am getting this messages and more importantly how do I get rid of them.
The installation is on a VM on Hyper-V.
today I tried to configure a network route to a host for testing my network interface. Code: route add 192.168.1.15 eth0 As I have to eth interfaces and both interface got their IP from DHCP (192.168.1.11 and 192.168.1.12) and are in the same subnet, I shut the other interface down:
Code: ifconfig eth1 down Then I tried to test the interface by doing a ping to 192.168.1.15.
Problem: When I unplug the cable from eth0 (and eth1 is still plugged) the ping still works. Somehow my linux (it's debian) powers up again eth0 and pings over this port.
How can I stop my linux doing this. I just want to have the route added only on the one interface - not the other. Is it maybe some case of a default-gateway?
Config: Squeeze, 2.6.32-5-amd64I just installed squeeze and the network is up and nm-manager deamon if working but the Gnome applet doesn't seem to work as usual. It indicates no network although the network is available as indicated by ifconfig and route below. When I switch WiFi on, the nm works flawlessly. When I click on the applet icon it says "Wired Network: device not supported" (or similar, msg in french is

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?

Network Interface is wlan0 (Wireless LAN, home network through a Router) that requires a password using WPA2.
My question is how to start wlan0 through the command-line ?
I have a laptop connected to the the net thru an adsl modem, when I switch off the laptop network interface,(thru system-config-network) the light of the laptop network card plugged in the router stays on ( green) where as in my pc, when i do the same thing , the light of my pc network card goes off in the modem

I have currently had the need to go back to basic socket programming, and implemented a simple udp packet sender. But I realized I needed to be able to select which network interface to send the packets from.
The reason is so that one of the interfaces has vlan tagging, and I need my UDP packets to be accordingly vlan tagged. For example, one of the interfaces is eth1.200.
The following are the output of command "ifconfig -a":
[Code]....
The interface "eth0", which is down, was not displayed, but loopback interface has been displayed. So, how can I make my application display all interfaces, including the interfaces which are down, but excluding the loopback interface?
after restarting my Fedora 10 the eth0 interface is not up
after i manually restart the network service everything is OK but after restarting it is the same problem.
this is the interface config file:
/etc/sysconfig/networking/devices/ifcfg-eth0 /etc/sysconfig/networking/devices/ifcfg-eth0
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth0
HWADDR=00:0c:29:8b:82:6b
ONBOOT=yes

i know i can put the restart service command in the rc.local file but it not suppose to work this way.
I have dsl broadband shared through a Modem Bridge Mode forwarded to wireless router which is configured for dhcp lease to the clients(1 Desktop, 1 Laptop).

I'm having all sorts of problems connecting an access point to my computer, but here is one piece that I hope will get me going, if I can get it solved.My computer has two network interfaces, eth0 and eth1. eth1 connects to the cable modem and thence the world, and works fine. eth0 is supposed to connect to the access point over a private network.

View 4 Replies View Relatedthis is my first time here: I've been programming GUI software in C# in MonoDev for some time now. I just noticed that I can use my favorite language, C, with Glade to do the same thing. I've been going through some tutorials with a little frustration with them. Some seem to be written for older Glade versions.
The latest example had me save my Glade project to a "tutorial.glade" file. Then run it through a 'gtk-builder-convert' utility. Problem: the utility program returns errors indicating the the tutorial.glade file was written badly, that there is supposed to be a <glade-interface> tag that is missing.
