ssh:安全壳协议

netstat -an |grep 22

ssh 192.168.10.34

ssh的cp,类似上传下载

scp /etc/hosts 192.168.16.151:/tmp

ssh钥匙和锁：

ssh-keygen

ls /root/.ssh

id_rsa 钥匙

id_rsa.pub锁

ssh-copy-id -i python-web2

cd /root/.ssh

ls

cat authorzed_keys

服务端 cat authorzed_keys

ssh-copy-id -i rd_rsa.pub python-web2 -p 8888

 

加好端口，一般不是22，容易被攻击

ssh python-web2 -p 22
