解决ssh_exchange_identification:read connection reset by peer原因
本文发布于 10 年前, 内容可能已经过时或失效!
服务器改了密码，试过密码多次后出现： ``` ssh_exchange_identification: read: Connection reset by peer ``` 可以通过ssh -v查看连接时详情 ```bash ssh -v root@ip地址或域名 ``` 会出现以下信息： ``` OpenSSH_6.6.1, OpenSSL 1.0.1k-fips 8 Jan 2015 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 56: Applying options for * debug1: Connecting to xxx [xx] port 22. debug1: Connection established. debug1: identity file /home/yanue/.ssh/id_rsa type -1 debug1: identity file /home/yanue/.ssh/id_rsa-cert type -1 debug1: identity file /home/yanue/.ssh/id_dsa type -1 debug1: identity file /home/yanue/.ssh/id_dsa-cert type -1 debug1: identity file /home/yanue/.ssh/id_ecdsa type -1 debug1: identity file /home/yanue/.ssh/id_ecdsa-cert type -1 debug1: identity file /home/yanue/.ssh/id_ed25519 type -1 debug1: identity file /home/yanue/.ssh/id_ed25519-cert type -1 ``` 百度谷歌一大把，没用，最后找打解决方法： ``` vi /etc/hosts.allow ``` 全部注射，追加： ``` sshd: ALL ``` 重启ssh就ok了 ``` service sshd restart ``` 注：以上操作是进入阿里云CES连接管理终端后进行的 我猜是密码错误过多，被服务器拉黑的感觉。
