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.

CONFIGURATION

       The wireless tools that LinSSID uses require root privilege to access.  You  can  use  the
       gksudo program to run LinSSID from an ordinary user in X or run directly as root.

       To  use  as  normal user, you will need setup the SUDO system and call the gksudo program.
       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  a  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:

           $ gksudo linssid

       To  start  in  X  Window, click over the icon created in desktop menu. Note that this icon
       will execute the 'gksudo linssid'  command.  So,  will  you  need  the  /etc/sudoers  well
       configured to get success.

       The  other  way  to run LinSSID is to launch it from a root account or with su or sudo. To
       run directly as root, you will need to  use  the  xhost  command  to  grant  to  root  the
       necessary permission to use the X environment.
