Block Port

Hi all, We want to limit some ports only possible to be used by our application. In /etc/services we append those port numbers in the right syntax. However, it blocks the listed port numbers completely. How to let the system know it should open the port when we startup the right application ? with best wishes Zheng Sun _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail
