服務器改了密碼，試過密碼屢次後出現：nginx
ssh_exchange_identification: read: Connection reset by peer
能夠經過ssh -v查看鏈接時詳情服務器
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 ........
最後找打解決方法：markdown
vi /etc/hosts.allow
追加：less
sshd: ALL
重啓ssh就ok了ssh
service sshd restart
