       wavemon - a wireless network monitor


       wavemon [-h] [-i ifname ] [-g] [-v]


       wavemon  is  a ncurses-based monitoring application for wireless network devices. It plots
       levels in real-time as well as showing wireless and network related device information.

       The wavemon interface splits into different "screens".  Each screen  presents  information
       in  a  specific  manner. For example, the "info" screen shows current levels as bargraphs,
       whereas the "level" screen represents the same levels as a moving histogram.

       On startup, you'll see (depending on configuration) one of the different monitor  screens.
       At  the bottom, you'll find a menu-bar listing the screens and their activating keys. Each
       screen is activated by either the corresponding function key or the key  corresponding  to
       the first character of the screen name. The following screens can be selected:

       Info (F1 or 'i')
              This  is  the  most  comprehensive  screen.  It  displays  a  condensed overview of
              wireless-specific parameters and network statistics, as well as  bar  graphs.   The
              layout is arranged into several sub-sections.

              The  Interface section at the top shows information about the monitoring interface,
              including interface name, type, ESSID, and available encryption formats.

              Below, in the Levels section, you can see up to four bargraphs showing (1) relative
              signal  quality  and  (2) signal level in dBm. If the wireless driver also supports
              noise level information, additionally (3) noise level in dBm and (4)  Signal-Noise-
              Ratio  (SNR) in dB are shown.  The colour of the signal level bargraph changes from
              red to yellow and green at fixed levels. If thresholds have been set, two arrows on
              the signal level graph will show the positions of the current thresholds.

              The  Statistics  section  displays packet and byte counters and a few other packet-
              related statistics.

              The subsequent Info subsection lists the current operational mode and configuration
              of  the  wireless  interface.  What  parameters  are  actually shown depends on the
              capabilities and selected mode of your network device.

              Lastly, the Network section shows  network-level  parameters.  The  MAC-address  is
              resolved  from  ethers(5).  The  IPv4  address  is shown in CIDR notation (RFC 4632
              address/prefix_len format).  Since  often  those  two  values  also  determine  the
              broadcast  address (last 32 - prefix_len bits set to 1), that address is shown only
              if it does not derive from the interface address and prefix length.  Likewise,  the
              interface  MTU  is  shown  only if it differs from the default Ethernet MTU of 1500

       Level histogram (F2 or 'l')
              This is a full-screen histogram plot showing the evolution  of  levels  with  time.
              The  screen is partitioned into a grid, with dBm levels shown in green at the right
              hand side (depending on configuration).  At the very minimum, the evolution of  the
              signal-level   is   shown.   If  the  wireless  driver  also  supports  noise-level
              information, additionally a noise graph and associated SNR graph appear.

       Scan window (F3 or 's')
              A periodically updated network scan,  showing  access  points  and  other  wireless
              clients. It is sorted depending on sort_order and sort_ascending, see wavemonrc(5).
              Each entry starts with the ESSID, followed by the colour-coded MAC address and  the
              signal/channel  information.  A  green/red  MAC address indicates an (un-)encrypted
              access point, the colour changes to yellow for non-access points (in this case  the
              mode is shown at the end of the line). The uncoloured information following the MAC
              address lists relative and  absolute  signal  strengths,  channel,  frequency,  and
              station-specific   information.   The  station-specific  information  includes  the
              station type (ESS for Access Point, IBSS for Ad-Hoc  network),  station  count  and
              channel utilisation.

              A  status  line  at  the  bottom  informs  about  the  current sort order and a few
              statistics, such as most (least)  crowded  channels  (least  crowded  channels  are
              listed when sorting by descending channel).

              The  sort_order  can  also  directly  be  changed  via  these  keyboard  shortcuts:
              ascending, descending; by essid, signal, channel (C also with signal), mac address,
              or by open access (O also with signal).

       Preferences (F7 or 'p')
              This  screen  allows  you to change all program options such as interface and level
              scale parameters, and to save the new settings to the configuration file. Select  a
              parameter  with  <up>  and  <down>,  then change the value with <left> and <right>.
              Please refer to wavemonrc(5) for an in-depth description of applicable settings.

       Help (F8 or 'h')
              This page might show an online-help.

       About (F9 or 'a')
              Release information and contact URLs.

       Quit (F10 or 'q')
              Exit wavemon.

       Note: some operations, such as displaying  encryption  information  or  performing  scans,
       require  CAP_NET_ADMIN  privileges (see capabilities(7)). For non-root users, these can be
       enabled by installing wavemon setuid-root.


       -i interface
              override autodetection and use the specified interface.

       -g     check screen geometry: a minimum size is required for  proper  display;  this  flag
              adds  a  check  to  ensure it is sufficiently large. Enable this if window does not
              display properly.

       -h     print help and exit.

       -v     print version information and exit.
