解决ssh_exchange_identification:read connection reset by peer 原因

服务器改了密码，试过密码多次后出现：

1. ssh_exchange_identification: read: Connection reset by peer

可以通过ssh -v查看连接时详情

 

1. ssh -v root@ip地址或域名

会出现以下信息：

 

 

1. OpenSSH_6.6.1, OpenSSL 1.0.1k-fips 8 Jan 2015
2. debug1: Reading configuration data /etc/ssh/ssh_config
3. debug1: /etc/ssh/ssh_config line 56: Applying options for *
4. debug1: Connecting to xxx [xx] port 22.
5. debug1: Connection established.
6. debug1: identity file /home/yanue/.ssh/id_rsa type -1
7. debug1: identity file /home/yanue/.ssh/id_rsa-cert type -1
8. debug1: identity file /home/yanue/.ssh/id_dsa type -1
9. debug1: identity file /home/yanue/.ssh/id_dsa-cert type -1
10. debug1: identity file /home/yanue/.ssh/id_ecdsa type -1
11. debug1: identity file /home/yanue/.ssh/id_ecdsa-cert type -1
12. debug1: identity file /home/yanue/.ssh/id_ed25519 type -1
13. debug1: identity file /home/yanue/.ssh/id_ed25519-cert type -1
14. ........

百度谷歌一大把，没用，最后找打解决方法：

 

1. vi /etc/hosts.allow

全部注射，追加：

1. sshd: ALL

重启ssh就ok了

 

 

1. 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。
