开发板上没有ssh, 为了方便开发，编译安装Openssh到开发板
编译器

源码

编译
默认全部安装到/home/install目录

编译zlib

$ CC=arm-linux-gnueabihf-gcc AR=arm-linux-gnueabihf-ar LDSHARED=arm-linux-gnueabihf-gcc ./configure --prefix=/home/install/zlib

$ make

$ make install

编译openssl

$ ./Configure --prefix=/home/install/openssl os/compiler:arm-linux-gnueabihf-gcc

$ make

$ make install

编译openssh

$ ./configure --host=arm-linux-gnueabihf --with-libs --with-zlib=/home/install/zlib --with-ssl-dir=/home/install/openssl --disable-etc-default-login

$ make

安装到开发板
建立目录

确保目标板上有以下目录，若没有，则新建：

/usr/local/bin

/usr/local/etc

/usr/libexec

/var/run

/var/empty

复制文件

scp、sftp、ssh sshd、ssh-add、ssh-agent、ssh-keygen、ssh-keyscan共8个文件拷贝到目标板/usr/local/bin

moduli、ssh_config、sshd_config共3个文件拷贝到目标板 /usr/local/etc

sftp-server、ssh-keysign 共2个文件拷贝到目标板 /usr/libexec

修改/etc/passwd

打开 /etc/passwd 文件，在最后添加下面这一行：

sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/***in/nologin

如果开发板的 root 用户还没有密码，键入以下命令然输入两次密码来修改，否其他设备无法连接

$ passwd root

sshd 自启动建立启动脚本

$ vi /etc/init.d/sshd.sh

#!/bin/sh
if [ ! -x /usr/local/bin/sshd ]
then
exit 0
fi
if [ "$1" = "stop" -o "$1" = "restart" ]
then
echo "Stopping the ssh server: "
killall sshd
fi
if [ "$1" = "start" -o "$1" = "restart" ]
then
# assume if one key is missing, all are
if [ ! -f /usr/local/etc/ssh_host_rsa_key ]
then
echo "Generating keys for the ssh server: "
/usr/local/bin/ssh-keygen -t rsa -f /usr/local/etc/ssh_host_rsa_key -N ""
/usr/local/bin/ssh-keygen -t dsa -f /usr/local/etc/ssh_host_dsa_key -N ""
/usr/local/bin/ssh-keygen -t ecdsa -f /usr/local/etc/ssh_host_ecdsa_key -N ""
/usr/local/bin/ssh-keygen -t dsa -f /usr/local/etc/ssh_host_ed25519_key -N ""
fi
for i in ssh_host_rsa_key ssh_host_dsa_key ssh_host_ecdsa_key ssh_host_ed25519_key
do
chmod 600 /usr/local/etc/$i
done
#echo "Starting the ssh server:"
/usr/local/bin/sshd
fi
