# linssid(1)

graphical wireless scanner

## 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
```
