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.
