K I see tcpdump. &nbsp;How do I make it in run in the background. &nbsp;Lets say I want it to start logging on boot up, or when I login to the console, then when I log out of the console I want it to run without stopping. &nbsp;I tried putting &amp;&nbsp;behind it but it doesnt run in the background, in other words it closes when I log out.<br />

I wanted to use tethereal to capture packets, but I have to be logged into to use it. &nbsp;I want it to log packets, then those logs will be transfer via a script to another machine. &nbsp; &nbsp;I want it to continuously log packets. &nbsp;I really wish I could use tethereal... but I may not be able to. &nbsp;Any suggestions? Points split amongst answers.<br />
