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.
