ssh修改默认端口号后无法连接（提示ssh: Could not resolve hostname）

Posted 2020-11-26

ssh命令语法：
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]
[-b bind_address] [-c cipher_spec] [-D [bind_address:]port]
[-E log_file] [-e escape_char] [-F configfile] [-I pkcs11]
[-i identity_file] [-J [user@]host[:port]] [-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]] destination [command]
本地修改端口后无法连接ssh
C:Usersjition>ssh jition@127.0.0.1:2222
ssh: Could not resolve hostname 127.0.0.1:2222: 262273326252265300325342321371265304326367273372241243

解决方法：

    使用指定端口号登录(-l 表示login_name -p 表示端口号)

[cqs@centos7 ~]$ ssh -l jition 192.168.1.105 -p 2222

The authenticity of host ‘[192.168.1.110]:2222 ([192.168.1.110]:2222)‘ can‘t be established.
ECDSA key fingerprint is SHA256:Tui3jBxEkVlIvIlMGbv2SoijP9xP4bPflwoUPV+gX4o.
