在自己局域网连接ssh到自己的小主机服务器上的时候发现执行ssh root@192.168.2.166回车之后，在输入密码之前要等好长一段时间，至少需要几秒到十几秒钟。
1.通过 ssh -v root@192.168.2.166 查看链接详细信息
[root@staryjie ~]# ssh -v root@192.168.2.166 OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5 debug1: Connecting to 192.168.2.166 [192.168.2.166] port 22. debug1: Connection established. debug1: identity file C:\\Users\\StaryJie/.ssh/id_rsa type 0 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_rsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_dsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_ecdsa type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_ecdsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_ed25519 type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_ed25519-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_xmss type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\StaryJie/.ssh/id_xmss-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_for_Windows_7.7 debug1: Remote protocol version 2.0, remote software version OpenSSH_7.4 debug1: match: OpenSSH_7.4 pat OpenSSH* compat 0x04000000 debug1: Authenticating to 192.168.2.166:22 as 'root' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: curve25519-sha256 debug1: kex: host key algorithm: ecdsa-sha2-nistp256 debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: compression: none debug1: kex: client->server cipher: chacha20-poly1305@openssh.com MAC: compression: none debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ecdsa-sha2-nistp256 SHA256:2ePNJ/cQW7AIsD+veSBc5XS2xy0kmB3W6Dk3uVnBwDQ debug1: Host '192.168.2.166' is known and matches the ECDSA host key. debug1: Found key in C:\\Users\\StaryJie/.ssh/known_hosts:11 debug1: rekey after 134217728 blocks debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: rekey after 134217728 blocks debug1: pubkey_prepare: ssh_get_authentication_socket: No such file or directory debug1: SSH2_MSG_EXT_INFO received debug1: kex_input_ext_info: server-sig-algs=<rsa-sha2-256,rsa-sha2-512> debug1: SSH2_MSG_SERVICE_ACCEPT received # 发现代码跑到这里的时候就卡住了 debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password debug1: Next authentication method: publickey debug1: Offering public key: RSA SHA256:Y5wPUy0NUgYMwwSO4juFhw52YyleflOzomjnNvsokXw C:\\Users\\StaryJie/.ssh/id_rsa debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password debug1: Trying private key: C:\\Users\\StaryJie/.ssh/id_dsa debug1: Trying private key: C:\\Users\\StaryJie/.ssh/id_ecdsa debug1: Trying private key: C:\\Users\\StaryJie/.ssh/id_ed25519 debug1: Trying private key: C:\\Users\\StaryJie/.ssh/id_xmss debug1: Next authentication method: password debug1: read_passphrase: can't open /dev/tty: No such file or directory root@192.168.2.166's password:</rsa-sha2-256,rsa-sha2-512>
2、解决方案
- 2.1 修改sshd配置文件 （通过 vi /etc/ssh/ssh_config 命令修改为以下查询结果内容）
[root@staryjie ~]# egrep -v "^#|^$" /etc/ssh/ssh_config Host * ForwardX11Trusted yes SendEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES SendEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT SendEnv LC_IDENTIFICATION LC_ALL LANGUAGE SendEnv XMODIFIERS SAPIAuthentication no UseDNS no [root@staryjie ~]#
- 2.2 添加本地电脑IP到/etc/hosts （通过 vi /etc/hosts 命令修改为以下内容，但是注意链接的IP 192.168.2.11 改为你自己需要连接服务器的IP地址）
[root@staryjie ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.2.11 windows [root@staryjie ~]#
- 2.3 执行下面的重启sshd命令
systemctl restart sshd.service
然后你在试试看链接服务器是不是非常了，无需连接前要等待几秒钟了。
