want to start script when wlan interface goes up

nrsorte · 03-23-2007, 03:03 AM

Hi,

I am writing a script to configure my wireless wlan settings. What should I do to automate it so that this script will run whenever wlan goes up. Please anyone guide me for this.

Thanks in advance.

Well I am not really sure what and when you want to run the script but maybe the search for ip-up.local could help.

In this script you can add things like mailing your actually ip.

If this does not help you may post some more infos.

Putting your distro in your profile will help get more accurate responses. Some distros use certain config files and scripts that may be a better fit toward a solution.

Hi there,

Try editing/making your /etc/sysconfig/network-scripts/ifcfg-interfacename file to something like;

TYPE=Wireless
DEVICE=device name here
HWADDR=
BOOTPROTO=dhcp
GATEWAY=ap's ip address here
DOMAIN=
ONBOOT=yes (if you want it to try and connect at boottime)
ONHOTPLUG=no
USERCTL=yes (Allows all users to start/stop the connection)
IPV6INIT=no
PEERDNS=no
ESSID=The Ap's SSID here.
CHANNEL=<the default AP channel here>
MODE=Auto
RATE=Auto

BTW, What distro and hardware are you using?

Cheers, and good luck.
Tom

For SuSE, the same config scripts are in /etc/sysconfig/network/. Some distro's may not have anything similar and you need to produce a script with iwconfig commands. That's why knowing the distro helps, and a logical place for it is in the profile instead of having to repeat it on every post.

Hi,

I have Linux-Pebble installed on my router boards and on them I want to run a script whenever my wlan goes up. After this in script I want to analyse wireless link status. Is it possible to do so on this Pebble? If so please could you guide me for the same.
