交叉编译OpenSSH for IXP425 ARM Platform by MVL 3.0

下载openssh 3.5p1 http://www.openssh.org/

1）在x86环境下

./configure --sysconfdir=/etc/ssh     ssh密钥目录

编辑Makefile

2）在ssh和sshd的编译选项上加-static参数，静态编译，动态编译出来总是找glic 2.2.4库。

strip ssh sshd

3）/etc/ssh下放上sshd_config和密钥文件

4）touch /var/log/lastlog

5）加入sshd用户

/etc/passwd

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

/etc/group

sshd:x:74:

/etc/shadow

sshd:!!:13196:0:99999:7:::

6）拷贝随机数设备

/dev/urandom

crw-r--r--    1 root     root       1,   9 Mar 23 09:42 /dev/urandom

7）运行sshd

sshd -d -4

-d   debug模式

-4   只支持ipv4
