解决ssh_exchange_identification:read connection reset by peer原因
本文发布于 9 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
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.

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。
