Description of problem:
During investigations we found, that the current available tcpdump binary didn't
drop root to pcap user like promised in man page.
Version-Release number of selected component (if applicable):
tcpdump-3.6.3-18.104.22.168 (perhaps others, too)
Steps to Reproduce:
1. Start tcpdump
2. Check for running user by ps -axu|grep tcpdump
Actual Results: # ps -axu|grep tcpdump
root 13531 0.0 0.9 3420 1176 pts/5 S 14:32 0:00 tcpdump not port
Expected Results: # ps -axu|grep tcpdump
pcap 13524 0.0 1.1 3712 1420 pts/5 S 14:31 0:00 [tcpdump]
I digged into the problem and found, that it's a compilation problem. The in the
SRPMS contained patch will be applied, patches "configure.in", but during
compile step, "autoheader" isn't executed.
Fix: patch spec file and rebuild binary packages
