SSH 和 SCP 命令简介

SSH

ssh -- OpenSSH SSH client (remote login program)

ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec] [-D [bind_address:]port] [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11] [-i identity_file] [-L address] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-Q query_option] [-R address] [-S ctl_path] [-W host:port] [-w local_tun[:remote_tun]] [user@]hostname [command]

• -b Use bind_address on the local machine as the source address of the connection. Only useful on systems with more than one address.
• -i Selects a file from which the identity (private key) for public key authentication is read.
• -l Specifies the user to log in as on the remote machine.
• -p Port to connect to on the remote host.

SCP

scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ... [[user@]host2:]file2

• -i Selects the file from which the identity (private key) for public key authentication is read.

-i 选项我曾在连接我的 Amazon Aws EC2 服务器的时候使用过，用于指定私有密钥文件，命令大致如下：

ssh -i "SecretKEY.pem" [email protected]
