源码包为：
openssh-4.6p1.tar.gz
openssl-0.9.8h.tar.gz
zlib-1.2.3.tar.gz
在主机中新建一个ssh目录，存放源文件
mkdir -p /root/ Gemini_v2_6_3-n/ssh
tar zxvf openssh-4.6p1.tar.gz /root/ Gemini_v2_6_3-n/ssh
tar zxvf zlib-1.2.3.tar.gz /root/ Gemini_v2_6_3-n/ssh
tar zxvf openssl-0.9.8h.tar.gz /root/ Gemini_v2_6_3-n/ssh
cd Gemini_v2_6_3-n
进入Gemini_v2_6_3-n后，使其为根目录
#chroot .
在ssh目录中新建一个install文件夹，作为安装目录。
mkdir -p /ssh/install
移植openssh4.6的步骤：
1.编译
(1)编译zlib
cd /ssh/zlib-1.2.3
./configure --prefix=/ssh/install/zlib-1.2.3
修改Makefile:
CC=gcc 改为:
CROSS=/usr/local/920t/bin/arm_920t_le-
CC=$(CROSS)gcc
LDSHARED=gcc 改为: LDSHARED=$(CROSS)gcc
CPP=gcc -E 改为: CPP=$(CROSS)gcc -E
AR=ar rc 改为: AR=$(CROSS)ar rc
开始编译:
make;
make install
(2)编译openssl
cd openssl-0.9.8h
./Configure -prefix=/ssh/install/openssl-0.9.8h os/complier:/usr/local/920t_le/bin/arm_920t_le-gcc
make
Make install
(3) 编译openssh:
cd openssh-4.6p1/
./configure--host=arm-none-linux--with-libs--with-zlib=/ssh/install/zlib-1.2.--with-ssl-dir=/ssh/install/openssl-0.9.8h--disable-etc-default-login CC=/usr/local/920t_le/bin/arm_920t_le-gcc AR=//usr/local/920t_le/bin/arm_920t_le-ar

Libraries: -lresolv -lcrypto -lutil -lz -lnsl -lcrypt
make
不要make install
(1) 将 openssh-4.6p1目录下的 sshd copy到nas中的public目录 再链接到 nas的/usr/sbin目录下
(2) copy scp sftp ssh ssh-add ssh-agent ssh-keygen ssh-keyscan 到nas 的 /usr/local/bin 目录中
copy sftp-server ssh-keysign 到/usr/local/libexec中
(3) 在nas下：
mkdir -p /usr/local/etc/
然后将openssh下的sshd_config,ssh_config 拷贝到该目录下
mkdir -p /var/empty/sshd
chmod 755 /var/empty
（4）在主机上：
ssh-keygen -t rsa1 -f ssh_host_key -N ""
ssh-keygen -t rsa -f ssh_host_rsa_key -N ""
ssh-keygen -t dsa -f ssh_host_dsa_key -N ""
将生成的ssh_host_* 6个文件copy到nas的/usr/local/etc/目录下
(5) 添加用户
将主机上/etc/目录下的passwd, 中的sshd用户追加到nas的/etc目录中的passwd中（具体代码为：
sshd:x:74:74:Privilege-separatedSSH:/var/empty/sshd:/sbin/nologin ）同时将passwd的最后/bin/bash 改为/bin/sh
再将主机中/etc目录下的group文件中的用户也同样追加到nas的/etc目录下的group（sshd:x:74:）文件。
4.测试
在nas中启动sshd服务: /usr/sbin/sshd
用putty 或者再主机中ssh 192.168.1.59
ssh自己

5. 在NAS中测试：如果中间出现问题的话，
一、可以将/root/.ssh文件删除再重新启动服务。
二、检查/usr/local/etc/sshd_config文件，看是否配置有问题。 （可能还有其他因素哦。）
附：openssh-5.0p1的移植跟上面的步骤一样，需要的环境支持也是一样。
