The kernel name defaults to \fB/vmunix\fP. +.PP +The default behaviour of \fBipfstat\fP +is to retrieve and display the accumulated statistics which have been +accumulated over time as the kernel has put packets through the filter. +.SH OPTIONS +.IP -o +display the filter list used for the output side of the kernel IP processing. +.IP -i +display the filter list used for the input side of the kernel IP processing. +.IP -v +turn verbose mode on.

For use in +combination with \fB-i\fP. +.SH SYNOPSIS +The role of \fBipfstat\fP is to display current kernel statistics gathered +as a result of applying the filters in place (if any) to packets going in and +out of the kernel. This is the default operation when no command line +parameters are present. +.PP +When supplied with either \fB-i\fP or \fB-o\fP, it will retrieve and display +the appropriate list of filter rules currently installed and in use by the +kernel. +.SH FILES +/dev/kmem +/vmunix +.SH SEE ALSO +ipf(1), ipfstat(1) +.SH BUGS +none known. -- cgit v1.2.3
