本客户端为Linux中兴认证客户端，已适配东莞理工学院城市学院。
参考Dot1x
访问Release Page，下载适合你的CPU的版本的ELF文件(zte-client-xxx.bz2)以及tesseract的训练数据(eng.traineddata.bz2)，并解压。 libcurl, libleptonica, libtesseract已静态链接，无需再安装此类库。
如mipsel-glibc:
mkdir -p /usr/share/tesseract-ocr/tessdata/
bunzip2 -kc eng.traineddata.bz2 > /usr/share/tesseract-ocr/tessdata/eng.traineddata
bunzip2 -kc zte-client-mipsel-glibc.bz2 > /usr/sbin/zte-client
chmod +x /usr/sbin/zte-client
TESSDATA_PREFIX="/usr/share/tesseract-ocr/tessdata/" \
/usr/sbin/zte-client \
--zteuser 201535010200 \
--ztepass 000000 \
--webuser 13800138000 \
--webpass 00000000 \
--webpass_encoder base64 \
--device eth0 \
--dhcpclient dhclient \
--daemon
需要安装以下运行库: libcurl, libleptonica, tesseract
apt-get install libcurl4-openssl-dev libleptonica-dev tesseract-ocr-dev tesseract-ocr-eng gcc git make cmake
git clone https://github.com/yzsme/zte-client.git
cd zte-client
cmake CMakeLists.txt
make
cp ./zte_client /usr/sbin/zte-client
Debian Jessie可参考此处安装Toolchains: CrossToolchains#For_jessie_.28Debian_8.29
OpenWRT/PandoraBox可到官网下载Toolchains
以Debian 9 Stretch，目标架构mipsel为例

通过nm可查看何函数使用了此版本的glibc：
nm zte-client | grep "GLIBC_x.xx"
如：
U fmemopen@GLIBC_2.22
libleptonica使用了fmemopen()，可通过汇编的.symver指定glibc版本。 查看目标计算机上的glibc版本，以mipsel为例，注意修改libc.so.6的路径：
bash - # /lib/mipsel-linux-gnu/libc.so.6

Support for some architectures added on, not maintained in glibc core.
BIND-8.2.3-T5B

For bug reporting instructions, please see:
<http://www.debian.org/Bugs/>.
可看出glibc版本为2.13。
修改libleptonica源码目录下的文件src/allheaders.h，在
#define LEPTONICA_ALLHEADERS_H
后加入
asm (".symver fmemopen, fmemopen@GLIBC_2.13");
然后重新编译libleptonica。
必要参数(使用-l, -r参数不要求以下参数):
-u, --zteuser 中兴认证用户名
-p, --ztepass 中兴认证密码
-d, --device 指定网卡设备，默认为第一个可用网卡设备
可选参数:
-w, --webuser 天翼认证用户名
-k, --webpass 天翼认证密码
-f, --pidfile pid文件路径，默认为/tmp/zte-client.pid
-m, --logfile 日志文件路径，前台运行模式下默认输出到标准输出，后台运行模式下默认重定向到/dev/null
-i, --dhcp 指定DHCP客户端，可以选择dhclient, udhcpc或none(代表不启用DHCP客户端)，默认为dhclient
-b, --daemon 以守护进程模式运行
-r, --reconnect 重新连接
-l, --logoff 注销
-h, --help 显示帮助信息
进行中兴认证与天翼认证，并以守护进程模式运行（注意参数--webpass_encoder base64，现在天翼认证密码需要base64编码）:
/usr/sbin/zte-client --zteuser username --ztepass password --webuser webusername --webpass webpassword --webpass_encoder base64 --device eth0 --daemon
仅进行天翼认证，并以守护进程模式运行：
/usr/sbin/zte-client --webuser webusername --webpass webpassword --webpass_encoder base64 --device eth0 --daemon
# 如果没有启用中兴认证，程序是不会自动开始天翼认证的，因此需要发送信号USR1告知程序可以开始天翼认证
killall -USR1 zte-client
注销:
/usr/sbin/zte-client -l
重新进行认证:
/usr/sbin/zte-client -r
