One possible solution?
$ sudo chmod +s /path/to/dumpcap
$ ls -l /path/to/dumpcap
-rwsr-sr-x 1 root root 66040 Oct 6 2010 /path/to/dumpcap*
$ whoami
dummy
$ dumpcap -w test.pcap
File: test.pcap
Packets: 19 Packets dropped: 0
$ ls -l test.pcap
-rw------- 1 dummy users 1920 Mar 21 12:06 test.pcap
In this case, the user and group are what I would expect.
Another possible solution?
$ sudo visudo
# Defaults specification
Defaults stay_setuid
:wq
$ sudo chmod -s /path/to/dumpcap
$ ls -l /path/to/dumpcap
-rwxr-xr-x 1 root root 66040 Oct 6 2010 /path/to/dumpcap*
$whoami
dummy
$ dumpcap -w test.pcap
File: test.pcap
Packets: 26 Packets dropped: 0
$ ls -l test.pcap
-rw------- 1 dummy root 2626 Mar 21 12:10 test.pcap
In this case, the user is what I would expect, but the group isn't. I'm not
sure how to get the group to be "users" instead of "root". I tried adding
preserve_groups to the sudoers file, but that didn't work.
