ssh_exchange_identification：远程主机关闭连接

我未能成功连接到服务器。以下是连接的输出

$ ssh -v [server]
OpenSSH_5.1p1 Debian-3ubuntu1, OpenSSL 0.9.8g 19 Oct 2007
debug1: Reading configuration data /home/tim/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config

ssh_exchange_identification: Connection closed by remote host`

有人知道哪里出了问题吗？谢谢！

答案1

检查您连接的 IP 是否显示在/etc/hosts.deny远程服务器上，并检查您是否有大量登录失败尝试/var/log/secure。如果有，请从两个文件中删除这些条目，然后您就可以重新登录。

答案2

sh_exchange_identification：即使密钥正确，远程主机也会关闭连接

通过控制台登录或尝试在 ssh 中多次登录

然后检查 /var/log/btmp 的权限，它必须是 600 chmod 600 /var/log/btmp

答案3

另外，尝试在不使用私钥的情况下登录。我知道的唯一方法是暂时移开你的私钥文件。
