NAME

       linssid - graphical wireless scanner

DESCRIPTION

       LinSSID  runs  over X Window and displays locally receivable 802.11 wireless attach points
       and ad hoc networks.

       A table is displayed with various parameters such as  MAC  address,  channel,  and  signal
       strength.  Graphs  are  also displayed with signal strength by channel and signal strength
       over time.

       LinSSID is graphically and functionally similar to inSSIDer (for  Microsoft  Windows)  and
       Wifi Analyzer (for Android).

       LinSSID can be used to measure the local performance or to search for an interference free
       channel to be set in a wireless router (access  point).   The  wireless  established  link
       won't  be  affected  by  these  operations because LinSSID needn't set the monitor mode in
       network interface.

       Some features:

              •  Table of locally  receivable  attach  points  with  many  columns  of  different
                 information and sortable and movable columns.

              •  Adjustable speed, real-time update.

              •  Graphs of signal strength by channel and over time.

              •  AP bandwidth displayed.

              •  Works on both 2.4 GHz and 5 GHz channels.

CONFIGURATION

       The  wireless  tools  that  LinSSID uses require root privilege to access. You can use the
       xhost command to run LinSSID as root in a X session created by a ordinary user. Example:

           $ xhost +local:
           # linssid
           $ xhost -local:

       Other way, maybe more secure, is using sudo. To configure the  SUDO  (/etc/sudoers  file),
       use  the  visudo  command as root (do not edit the /etc/sudoers file directly! visudo will
       perform syntax checks before write the final configuration):

           # visudo

       If needed, you can set a preferred editor using the EDITOR environment variable:

           # EDITOR=mcedit visudo

       The next step is grant access as root to linssid.  Considering  an  ordinary  user  called
       eriberto, you will need add the following line at end of file:

           eriberto  ALL = /usr/bin/linssid

       To start LinSSID, via command line, use:

           $ sudo linssid
