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
