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-3.6.3-17.7.3.2 (perhaps others, too) How reproducible: Always 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] Additional info: 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.

Verified, this is allocated CAN-2003-0194 and will be fixed in upcoming errata RHSA-2003:174 (Red Hat Linux) and RHSA-2003:151 (Red Hat Enterprise Linux)
