Yes. But when I exit tcpdump, my networking is dead again.

Using -p, my networking is dead.

With -p, I have outbound only:

Thanks for the note.

I tried taking interface "down", "delete" and brought back "up" and 
assigned IP again, but didn't work.

I seem to recall this happened to me before. But I can't find in my email 
archives and don't see in my journal.

I will keep tcpdump running until I can reboot system.

Or how do I turn it on with ifconfig? I don't see in ifconfig, tlp or 
ukphy man pages.
