Yes, and Yes.

I am running Rhat 7.3, and everything is working fine if I type 'eth1' in
the capture window.  But like Guy said it is not finding it by default under
that capture window.  

For now I will hand type it in, but that sounds like something we should
fix.


Thanks

The problem is, I suspect, that, on Linux, SIOCGIFCONF only finds
interfaces that have IP addresses, and that's what Ethereal uses to get
the list of interfaces.

The "pcap_findalldevs()" routine in recent libpcaps will, on Linux, also
look in "/proc/net/dev" for interfaces.  At some point we should
probably arrange that Ethereal use "pcap_findalldevs()" if present.
