Apfree-WiFidog is an open source captive portal solution for wireless router which with embeddable Linux(LEDE/Openwrt).

中文介绍

In fact, the title should be why we choose apfree-wifidog, the reason was the following:

Stable

apfree-wifidog was widely used in tens of thousands device, which were running in business scene. In order to improve its stable, we rewrite all iptables rule by api instead of fork call, which will easily cause deadlock in multithread-fork running environment

Efficent

apfree-wifidog's http request-response is more quick, u can find statistic data in our test document

More features

apfree-wifidog support https redirect, mac temporary-pass, ip,domain,pan-domain,white-mac,black-mac rule and etc. all these rules can be applied without restarting wifidog

Compitable with wifidog authentication server

u don't need to modify your wifidog authentication server to adapt apfree-wifidog

Please go to package_apfree_wifidog

before starting apfree-wifidog, we must know how to configure it. apfree-wifidog use OpenWrt standard uci config system, all your apfree-wifidog configure information stored in /etc/confg/wifidogx, which will be parsed by /etc/init.d/wifidogx to /tmp/wifidog.conf, apfree-wifidog's real configure file is /tmp/wifidog.conf

The default apfree-wifidog UCI configuration file like this:

config wifidog
    option  gateway_interface   'br-lan'
    option  auth_server_hostname    'wifidog.kunteng.org.cn'
    option  auth_server_port    8001
    option  auth_server_path    '/wifidog/'
    option  check_interval      60
    option  client_timeout      72000
    option  httpd_max_conn      200
    option  pool_mode           1
    option  thread_number       5
    option  queue_size          20
    option  wired_passed        0
    option  enable      0

auth_server_hostname was apfree-wifidog auth server, it can be domain or ip; wifidog.kunteng.org.cn is a free auth server we provided, it was also open source

pool_mode means whether to support thread pool, default supporting it cause this mode is more efficient according to our testing, u can tune thread_number and queue_size to adapt your environment, but we suggest using default value

wired_passed means whether LAN access devices need to auth or not, value 1 means no need to auth

enable means whether start apfree-wifidog when we executed /etc/init.d/wifidogx start, if u wanted to start apfree-wifidog, you must set enable to 1 before executing /etc/init.d/wifidogx start

In order to support https redirect, apfree-wifidog need x509 pem cert and private key, u can generate youself like this:

PX5G_BIN="/usr/sbin/px5g"
OPENSSL_BIN="/usr/bin/openssl"
APFREE_CERT="/etc/apfree.crt"
APFREE_KEY="/etc/apfree.key"

generate_keys() {
    local days bits country state location commonname

    # Prefer px5g for certificate generation (existence evaluated last)
    local GENKEY_CMD=""
    local UNIQUEID=$(dd if=/dev/urandom bs=1 count=4 | hexdump -e '1/1 "%02x"')
    [ -x "$OPENSSL_BIN" ] && GENKEY_CMD="$OPENSSL_BIN req -x509 -sha256 -outform pem -nodes"
    [ -x "$PX5G_BIN" ] && GENKEY_CMD="$PX5G_BIN selfsigned -pem"
    [ -n "$GENKEY_CMD" ] && {
        $GENKEY_CMD \
            -days ${days:-730} -newkey rsa:${bits:-2048} -keyout "${APFREE_KEY}.new" -out "${APFREE_CERT}.new" \
            -subj /C="${country:-CN}"/ST="${state:-localhost}"/L="${location:-Unknown}"/O="${commonname:-ApFreeWiFidog}$UNIQUEID"/CN="${commonname:-ApFreeWiFidog}"
        sync
        mv "${APFREE_KEY}.new" "${APFREE_KEY}"
        mv "${APFREE_CERT}.new" "${APFREE_CERT}"
    }
}

or when u start /etc/init.d/wifidogx start, it will generate it automatically

apfree wifidog's official auth server is wwas, which support wfc pay and weixin auth-mode and more auth-way will be support.
