When I attempt to run the following command...

...I get the following error.
tcpdump: /data/capture_rotate_2012_02_03.pcap0: Permission denied
What are the permissions on the /data/ directory? Does the first command
work without the shell expansion date command?
The seed file is just a 4MB file that I had created using dd.
-rw-r--r-- 1 root root 4.0M Feb 3 07:29 /data/502_capture-seed.txt
It looks like the '-F' is for a tcpdump style filter. I'm not sure how
you'd create that with dd...
Good luck,
MJ
