Two questions

Is it possible to do a negative regex match on flow labels?  I tried doing a negative lookahead -M label="(?!whitelisted)", but got an error:

-bash: !whitelisted: event not found

I can do a reverse match using egrep if I have to.  But negative label matching would be a nice feature.

Second question...  When an ra* client connects to argusd or radium and sees a flow that was established before it connected, what is the logic that the client uses to guess the direction of the flow?  And is there any way to influence it or control it?  It would be great if Argus could use something like an iana label file or NMAP scan so that known open ports on a server would be given precedence as the destination.

Thanks Carter and the rest of the community for all the help!
