mheard [-d cmns] [-n] [-o cfpt] [-v] [port...] DESCRIPTION
Mheard displays information about most recently heard AX.25 callsigns, the interface upon which they were heard, the total packets heard, the time at which the last one was heard and other information. Mheard displays different information, in different orders depending on the settings of the arguments. Information on specific ports can be displayed by giving the port names as arguments. OPTIONS
-d cmns Sets the information that is displayed for each AX.25 callsign heard. The different arguments are: c Display all the information with regard to callsigns, from-callsign, to-callsign, port name, and any digipeaters that may be in use. m Display miscellaneous information, the from-callsign, port name, no frames heard, the last type of frames heard, and which different PIDs have been heard from that station. n Display the default information. This is the from-callsign, port name, no frames heard and the date and time last heard. s Displays statistics about the station heard, the from-callsign, port name, no I frames, no S frames, no U frames, time first heard, and time last heard. -n Supress the displaying of titles. -o cfpt Sets the ordering of the information displayed. The meanings of the different arguments are: c Sort list by from-callsign. f Sort list by number of frames heard. p Sort list by port name. t Sort list by the time last heard, this is the default. -v Display the version.

mheardd - collect information about packet activity SYNOPSIS
mheardd [-f] [-l] [-n number] [-p [!]port1[,port2,..]] [-v] DESCRIPTION
Mheardd is a daemon that collects the statistics about the activity on all the AX.25 channels that are configured. The list generated is available for viewing by the mheard(1) program. The information collected is a superset of the information normally collected by similar mheard programs and this is reflected in the options available for the viewing program. Logging to the system log file may be enabled which will enable monitoring of pathalogical conditions, for example invalid frame types and invalid/unknown protocol IDs. OPTIONS
-f Deletes the existing mheard logging file at program startup, this is not the default. -l Enables logging to the system log file. The default is off. -n number Sets the number of entries in the activity list file, the default is 100. The minimum value allowed is 10 and the maximum is 1000. -p [!]port1[,port2,..] With -p, you instruct mheardd to only listen on specified ax25 ports. You may give more ports, seperated by ','. If you intro- duce the port(s) by a leading '!', then mheardd will listen on all ports except those you specified. -v Display the version. FILES
