2、在linux的服务器 40.129配置

在linux 40.129的服务器配置:
root@kali:~/.ssh# 
root@kali:~/.ssh# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0c:29:ee:b2:1f  
          inet addr:192.168.40.129  Bcast:192.168.40.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:feee:b21f/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:917 errors:0 dropped:0 overruns:0 frame:0
          TX packets:743 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:377348 (368.5 KiB)  TX bytes:103578 (101.1 KiB)
          Interrupt:19 Base address:0x2000 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:32 errors:0 dropped:0 overruns:0 frame:0
          TX packets:32 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:1920 (1.8 KiB)  TX bytes:1920 (1.8 KiB)

root@kali:~/python# sudo apt-get install openssh-server

root@kali:~/python# cd ~/.ssh/
root@kali:~/.ssh# ls

3、再到客户端 40.128使用ssh root@192.168.40.129登录40.129服务器(登录密码:1736*****(打码))

root@kali:~/.ssh# ssh root@192.168.40.129
Enter passphrase for key '/root/.ssh/id_dsa':
