linux – SSH连接错误：ssh_exchange_identification：读取：由peer重置连接

当我尝试通过SSH连接到服务器时,我收到以下错误,

[root@oneeighty ~]# ssh -vvv -p 443 [e-mail]
OpenSSH_4.3p2,OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

debug1: identity file /root/.ssh/id_dsa type -1
debug1: loaded 3 keys
ssh_exchange_identification: read: Connection reset by peer

我检查了服务器和客户端上的SSH配置,没有问题.

重新启动服务器上的SSH服务,然后重新启动服务器/客户端,但问题仍未解决.

解决方法

这可能是许多事情的结果.

您可以快速尝试的几件事情如下,

>在/etc/hosts.deny中查找sshd：ALL等条目
>也许,将sshd：ALL添加到/etc/hosts.allow
>您的SSHD的HostKeys可能已损坏.它们存在于/ etc / ssh /目录中.您可以删除它们并重新启动sshd,它将重新生成它们.如果出现错误,请使用以下命令

$ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
$ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
$ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key
$/etc/init.d/sshd start
