DESCRIPTIONLinSSID 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.
CONFIGURATIONThe 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):
# visudoIf needed, you can set a preferred editor using the EDITOR environment variable:
# EDITOR=mcedit visudoThe 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/linssidTo start LinSSID, via command line, use:
$ gksudo linssidTo 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.
