Newbie (both Ethereal and Linux) alert ! (I.e.
please be gentle...). If you can suggest a more appropriate list, feel
free.
I need to capture stuff automatically - generate a
new capture file once per day. I.e. Stop the previous day's capture and Start a
new capture. I think I know how to use crontab to create an entry, but haven't
got a clue how to write a suitable .job file for the crontab entry
!
I'd like to create the files with the system date
forming the first part of the filename, e.g. 20010329_dbcsup.cap.
I'm not sure whether it's best to actually
cron-schedule Ethereal itself to do the captures, or just use tcpdump (for later
analysis with Ethereal, of course). (I need to capture *some* large packets -
but think I know how to tell tcpdump to do that on it's command line - as part
of the cron .job file.)
Any kind soul that can help ?
TIA, Jon H-D
