Wireshark · Ethereal-dev: Re: [Ethereal-dev] Number of capture interfaces

[Miha Jemec <m.jemec@xxxxxxxxxxx>]

Thanks for the response. I looked the output of the ifconfig command and
those interfaces are up but lack of IP address. But is this behaviour OK
since you can still capture on those interfaces? 

I posted a duplicated message on this topic due to mail delivery
problem. Please ignore.

Regards, Miha
