ssh远程链接不上

今天远程自己的一台阿里服务器，突然链接不上。 我使用 ssh 链接提示：ssh_exchange_identification: read: Connection reset by peer   后来我在链接的时候 带上-v参数，进行输出调试信息，信息如下： OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to 10.x.x.x.x port 22. debug1: Connection established. debug1: identity file /home/kevin/.ssh/id_rsa type 1 debug1: identity file /home/kevin/.ssh/id_rsa-cert type -1 debug1: identity file /home/kevin/.ssh/id_dsa type -1 debug1: identity file /home/kevin/.ssh/id_dsa-cert type -1 debug1: identity file /home/kevin/.ssh/id_ecdsa type -1 debug1: identity file /home/kevin/.ssh/id_ecdsa-cert type -1 debug1: identity file /home/kevin/.ssh/id_ed25519 type -1 debug1: identity file /home/kevin/.ssh/id_ed25519-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 ssh_exchange_identification: read: Connection reset by peer     遇见过的，帮忙处理下。等待救国方针，谢谢
