安装编译器和依赖：
zypper install zlib-devel gcc
配置安装目录：
./configure --prefix=/opt/dropbear
编译安装
make make install
添加配置文件及目录
cd /opt/dropbear mkdir -p etc/sysconfig touch etc/sysconfig/dropbear
修改配置文件内容(第一行其实没得什么用)
# the TCP port that Dropbear listens on DROPBEAR_PORT=22222 # any additional arguments for Dropbear DROPBEAR_EXTRA_ARGS= # specify an optional banner file containing a message to be # sent to clients before they connect, such as "/etc/issue.net" DROPBEAR_BANNER="" # RSA hostkey file (default: /etc/dropbear/dropbear_rsa_host_key) DROPBEAR_RSAKEY="/etc/dropbear/dropbear_rsa_host_key" # DSS hostkey file (default: /etc/dropbear/dropbear_dss_host_key) DROPBEAR_DSSKEY="/etc/dropbear/dropbear_dss_host_key" # port OPTIONS=-p 3389 -R
编写systemd服务文件dropbear.service
