This article will explain in detail how to open WI-FI hotspots in Debian. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Installation environment

Operating system: Debian Gnu/Linux 8.3Kernel: linux-image-4.3.0-0.bpo.1-amd64 Network Card: Tenda W311M 150m Mini Wireless USB Network Card

1. Prepare the environment

Add Source Warehouse

Execute vi / etc/apt/sources.list and add the following source address:

Deb http://ftp.cn.debian.org/debian/ jessie-backports main contrib non-free

Install dependent packages

Install the latest kernel and related software packages to avoid errors in compiling Hostapd, and execute the following commands in turn:

Apt-get updateapt-get install linux-image-4.3.0-0.bpo.1-amd64apt-get install linux-headers-4.3.0-0.bpo.1-all-amd64apt-get install pkg-configapt-get install libssl-devapt-get install gettextapt-get install opensslapt-get install libnl-genl-3-devapt-get install libnl-genl-3- 200apt-get install libnl-3-devapt-get install libnl-3- 200apt-get install hostapd2, compile, configure hostapd software

Download the hostapd package

Go to http://w1.fi/hostapd/ website to download hostapd-2.5.tar.gz file

Wget http://w1.fi/releases/hostapd-2.5.tar.gz

Decompression

Extract and copy the configuration file

Tar-zxvf hostapd-2.5.tar.gzcd hostapd-2.5cp defconfig .config

Use the vi .config command to modify the file as follows:

# Use libnl v2.0 (or 3.0) libraries.CONFIG_LIBNL20=y# Use libnl 3.2 libraries (if this is selected, CONFIG_LIBNL20 is ignored) CONFIG_LIBNL32=y# IEEE 802.11n (High Throughput) supportCONFIG_IEEE80211N=y

Save exit, compile and install:

Makemake install

The system will generate two executable files named hostapd and hostapd_cli in the / usr/local/bin directory.

Modify profile parameters

Copy the hostapd configuration file to the / etc/hostapd/ folder and modify the related fields to read as follows:

Cp hostapd.conf / etc/hostapd/vi / etc/hostapd/hostapd.confinterface=wlan1driver=nl80211ssid=LONUXPROBEhw_mode=gchannel=7macaddr_acl=0auth_algs=3ignore_broadcast_ssid=0wmm_enabled=1ieee80211n=1ht_capab= [HT40-] [SHORT-GI-20] [SHORT-GI-40] wpa=2wpa_passphrase=linuxprobemacaddr_acl=0auth_algs=1ignore_broadcast_ssid=0wpa_key_mgmt=WPA-PSKwpa_pairwise=TKIPrsn_pairwise=CCMP

Modify the daemon target location

Use vi to edit the file with the following modifications:

Vi / etc/default/hostapdDAEMON_CONF= "/ etc/hostapd/hostapd.conf"

Modify the service script target location

Edit the hostapd service script as follows:

Vi / etc/init.d/hostapdDAEMON_SBIN=/usr/local/bin/hostapd

And add the following to the next line of start):

Sed-I'/\ [keyfile\] / a unmanaged-devices=mac:c8:3a:35:cb:18:e0' / etc/NetworkManager/NetworkManager.conf ip addr add 192.168.11.1 POSTROUTING 24 dev wlan1 echo "1" > / proc/sys/net/ipv4/ip_forward iptables-t nat-A POSTROUTING-o wlan0-j MASQUERADE sleep 2

Add the following to the next line of stop):

Sed-I'/ ^ unmanaged-devices=mac:c8:3a:35:cb:18:e0/d' / etc/NetworkManager/NetworkManager.conf echo "0" > / proc/sys/net/ipv4/ip_forward ip addr del 192.168.11.1 wlan0 24 dev wlan1 iptables-t nat-D POSTROUTING-o wlan0-j MASQUERADE sleep 2

Add the following to the next line of reload):

Sed-I'/ ^ unmanaged-devices=mac:c8:3a:35:cb:18:e0/d' / etc/NetworkManager/NetworkManager.conf echo "0" > / proc/sys/net/ipv4/ip_forward ip addr del 192.168.11.1 wlan0 24 dev wlan1 iptables-t nat-D POSTROUTING-o wlan0-j MASQUERADE sed-I'/\ [keyfile\] / a unmanaged-devices=mac:c8:3a:35:cb:18:e0' / etc/ NetworkManager/NetworkManager.conf ip addr add 192.168.11.1 NetworkManager/NetworkManager.conf ip addr add 24 dev wlan1 echo "1" > / proc/sys/net/ipv4/ip_forward iptables-t nat-A POSTROUTING-o wlan0-j MASQUERADE sleep 2

Save and exit, and * * (set parameters mac and ip according to your own situation) * * reconfigure the script file:

Systemctl daemon-reload3, install and configure dnsmasq software

Install dnsmasq

Apt-get install dnsmasq

Modify the configuration file of dnsmasq

Vi / etc/dnsmasq.confresolv-file=/etc/resolv.dnsmasq.confserver=/cn/114.114.114.114server=/taobao.com/114.114.114.114server=/google.com/8.8.8.8listen-address=127.0.0.1192.168.11.1dhcp-range=192.168.11.50192.168.11.150,12hdhcp-option=3192.168.11.1dhcp-option=6192.168.11.1cache-size=1024conf-dir=/etc/dnsmasq.d

Modify the configuration file

Vi / etc/resolv.dnsmasq.confnameserver 114.114.114.114nameserver 223.5.5.5nameserver 223.6.6.6

Modify the configuration file

Vi / etc/resolv.confnameserver 127.0.0.14, start related services

Start the service

Use the commands separately:

Systemctl enable dnsmasq.servicesystemctl disable hostapd.service

Turn both services on and off, and then use the command when you need to use hotspot mode:

Systemctl start hostpad.serive

Users can use the hotspot name LINUXPROBE, password linuxprobe, gateway address and DNS are 192.168.11.1 80211N protocol unlimited hotspot to connect to the Internet!
