Specifically, it displays counts of IP, non-IP, and bad IP packets (packets with IP checksum errors). It also includes an activity indicator, which shows the number of kilobits and packets the interface sees per second. All figures are for incoming and outgoing packets. (Again, considering promiscuous mode for LAN interfaces, which simply causes the machine to intercept all packets). This is useful for general monitoring of all attached interfaces. If byte counts and additional information are needed for a specific interface, the <I CLASS="EMPHASIS" >Detailed interface statistics</I > option is also available.</P ><P > The activity indicators can be toggled between kbits/s and kbytes/s with the <I CLASS="EMPHASIS" >Activity mode</I > configuration option.</P ><P > The general statistics window will dynamically add new entries as packets from newly-created interfaces (e.g. new PPP interfaces) are intercepted. Long lists can be scrolled with the Up, Down, PgUp, and PgDn keys.</P ><P >This monitor is affected by IPTraf's <A HREF="filters.html" >filters</A > as described in Chapter 7.</P ><P > Copies of the statistics are written to the log file <TT CLASS="FILENAME" >iface_stats_general.log</TT > at regular intervals if logging is enabled.
