系统配置 1.在 Remote Host 启动sshd [root@Remote root]/usr/loca/sbin/sshd2 2 在 Local Host 添加用户账号 如 bill [root@Local root] useradd bill [root@Local root] passwd bill 3 在Client 上建立用户的公共和私人密钥 以bill登陆到 Local Host 上 [bill@Local local]$ ssh-keygen Generating 1024-bit dsa key pair 9 o.oOo..oOo.o Key generated. 1024-bit dsa, created by bill@Local Wed Sep 23 07:11:02 1998 Passphrase :输入一些字符，不超过20个 Again :重复输入一遍 Private key saved to /home/bill/.ssh2/id_dsa_1024_a 4 在Client 上建立用户的认证文件 以bill登陆到 Local Host 上 [bill@Local local]$cd ~/.ssh2 [bill@Local local]$echo "IdKey id_dsa_1024_a" > identification 4. 在 Remote Host 添加用于远程登陆的用户账号 如 bill [root@Remote root]# useradd bill [root@Remote root]# passwd bill 5. 以bill登陆到 Remote Host 上 [bill@Remote local]$ ssh-keygen Generating 1024-bit dsa key pair 9 o.oOo..oOo.o Key generated. 1024-bit dsa, created by bill@Local Wed Sep 23 07:11:02 1998 Passphrase :输入一些字符，不超过20个 Again :重复输入一遍 Private key saved to /home/bill/.ssh2/id_dsa_1024_a 6. 以bill登陆到 Local Host [bill@Local local]$ cd ~ [bill@Local local]$ cp ./.ssh2/id_dsa_1024_a.pub Local.pub 以bill FTP Remote Host [bill@local bill]$ ftp local ftp> lcd ~/.ssh2 ftp> cd ~/.ssh2 ftp> put Local.pub ftp> bye 以bill Telnet Remote Host [bill@local bill]$ telnet local [bill@remote bill]$ cd ~/.ssh2 [bill@remote .ssh2]$echo "Key Local.pub" > authorization
