[Bridge] loosing network connectivity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks,

I'm new on brctl and didn't find the archive of this list, so, sorry if my
question was previously answered.

Well, my problem is: when I run "brctl addif pan0 eth0" my network
connection is lost. If I execute "brctl delif pan0 eth0" the connection is
restablished.

Does anyone knows what is missing here??
My full script is typed bellow.

Thanks in advance for any help
