## Features
|
||||
* Create an AP (Access Point) at any channel.
|
||||
* Choose one of the following encryptions: WPA, WPA2, WPA/WPA2, Open (no encryption).
|
||||
* Hide your SSID.
|
||||
* Disable communication between clients (client isolation).
|
||||
* IEEE 802.11n & 802.11ac support
|
||||
* Internet sharing methods: NATed or Bridged or None (no Internet sharing).
|
||||
* Choose the AP Gateway IP (only for 'NATed' and 'None' Internet sharing methods).
|
||||
* You can create an AP with the same interface you are getting your Internet connection.
|
||||
* You can pass your SSID and password through pipe or through arguments (see examples).

## Installation
|
||||
|
||||
### Generic
|
||||
|
||||
git clone https://github.com/lakinduakash/linux-wifi-hotspot
|
||||
cd linux-wifi-hotspot/src/scripts
|
||||
make install
|
||||
|
||||
### ArchLinux
|
||||
|
||||
pacman -S create_ap
|
||||
|
||||
### Gentoo
|
||||
|
||||
emerge layman
|
||||
layman -f -a jorgicio
|
||||
emerge net-wireless/create_ap
|
||||
|
||||
## Examples
|
||||
|
||||
### No passphrase (open network):
|
||||
|
||||
create_ap wlan0 eth0 MyAccessPoint
|
||||
|
||||
### WPA + WPA2 passphrase:
|
||||
|
||||
create_ap wlan0 eth0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### AP without Internet sharing:
|
||||
|
||||
create_ap -n wlan0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### Bridged Internet sharing:
|
||||
|
||||
create_ap -m bridge wlan0 eth0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### Bridged Internet sharing (pre-configured bridge interface):
|
||||
|
||||
create_ap -m bridge wlan0 br0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### Internet sharing from the same WiFi interface:
|
||||
|
||||
create_ap wlan0 wlan0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### Choose a different WiFi adapter driver
|
||||
|
||||
create_ap --driver rtl871xdrv wlan0 eth0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### No passphrase (open network) using pipe:
|
||||
|
||||
echo -e "MyAccessPoint" | create_ap wlan0 eth0
|
||||
|
||||
### WPA + WPA2 passphrase using pipe:
|
||||
|
||||
echo -e "MyAccessPoint\nMyPassPhrase" | create_ap wlan0 eth0
|
||||
|
||||
### Enable IEEE 802.11n
|
||||
|
||||
create_ap --ieee80211n --ht_capab '[HT40+]' wlan0 eth0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### Client Isolation:
|
||||
|
||||
create_ap --isolate-clients wlan0 eth0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### Assign IP address to a hosts listed in /etc/hosts:
|
||||
|
||||
create_ap --dhcp-hosts "host1 host2" wlan0 eth0 MyAccessPoint MyPassPhrase
|
||||
|
||||
### Assign IP address to two hosts not listed in /etc/hosts:
|
||||
|
||||
create_ap --dhcp-hosts "host1,192.168.12.2 host2,192.168.12.3" wlan0 eth0 MyAccessPoint MyPassPhrase
|
||||
|
||||
Use a space to separate multiple `dhcp-host` definitions. Reference [dnsmasq.conf.example](https://github.com/imp/dnsmasq/blob/770bce967cfc9967273d0acfb3ea018fb7b17522/dnsmasq.conf.example#L238) for other valid ways to define hosts, such as by MAC address.
|
||||
|
||||
## Systemd service
|
||||
|
||||
Using the persistent [systemd](https://wiki.archlinux.org/index.php/systemd#Basic_systemctl_usage) service
|
||||
|
||||
### Start service immediately:
|
||||
|
||||
systemctl start create_ap
|
||||
|
||||
### Start on boot:
|
||||
|
||||
systemctl enable create_ap
