Network card connection state

eeades · 02-28-2005, 02:51 PM

Does anyone know where the driver for the realtek cards would put the connection status of the cable? What I would like to do is modify the startup script so that DHCP is not trying to aquire an address if the cable is not hooked up. If I am using wireless, or in a location that I do not have/need network access, I do not want to wait for DHCP to decide that it won't get a response.

Thanks,

Eric

We do not mess with startup scripts, we add and remove services or devices using the appropriate tools. i.e. ifconfig eth0 down etc. etc.....

You should be able to use mii-tool to determine this. This SHOULD work:

Code:

if [ `/sbin/mii-tool eth0 | grep -ci 'link up'` -eq 0 ]
then echo "Link is down"
else echo "Link is up"
fi
