用证书登陆
首先生成一个公钥和一个私钥
#ssh-keygen -b 1024 -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/root/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_dsa.
Your public key has been saved in /root/.ssh/id_dsa.pub.
The key fingerprint is:
ba:71:52:87:11:cd:74:8a:bc:91:ba:a3:51:af:95:77 root@liuqi.cutbag
The key
然后做一个ssh服务端的公钥证书
cat id_rsa.pub > authorized_keys
接着配置一下ssh服务配置文件/etc/ssh/sshd_config
把如下几句注释掉的内容打开
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
然后将私钥id_rsa文件copy到windows里，把内容copy到一个新的文本文件里。
然后在windows下用puttygen生成新文件，就可以了
