編輯sshd配置文件

[root@check2 .ssh]# vim /etc/ssh/sshd_config 47 RSAAuthentication yes48 PubkeyAuthentication yes42 PermitRootLogin yes61 IgnoreRhosts yes66 PasswordAuthentication no122 UseDNS no[root@check2 .ssh]# service sshd restart 停止 sshd： [確定] 正在啟動 sshd： [確定][root@check2 .ssh]# sz id_rsa

導出后將id_rsa改個名字，然后導入Xshell

打開Xshell，使用快捷鍵 Alt+T+U（alt鍵按著不松，依次按T，U）

導入剛才的文件

登錄遠程機器

選擇剛才導入的文件確定即可
