Hi, I need to extend the sshknock example given in the shorewall port knocking doc to have a knock in sequence. What I really need is three tcp knocks in sequence, that opens three ports for that source IP. Is it worth trying to extend the SSHknock example? or should I have put the sequence in the rules file? dave ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf
