hi. at the very least, there is a doc bug here. before the last change to netstat.1, we showed -I and -f being compatible, in SYNOPSIS. in the most recent change to netstat.1, i removed that after some help from guenther in trying to track down what actually works. the -f text in the description of -I remained. i will try to work out whether it's a doc fix or a code fix (i.e. bug those who know). jmc
