服务器端用 sshd -d 开起来，客户端ssh -v链接，看看哪一部出的错。

[ivanlw]

@felix021 现在这样子完全连不上服务器怎么处理呢？是VPS……

[gamexg]

通过控制面板简单的直接重启试试，
不行的话在控制面板找找，里面应该有控制台，通过他连vps。

[felix021]

@ivanlw 你先ssh -vvv看看有没可以解决的异常；换用putty/securecrt之类其他客户端试试。不行的话就找卖家，VPS卖家一般都可以提供其他方式（例如vnc）提供console登录，是需要ssh。

[BOYPT]

被黑了吧，glibc等重要库被替换，但是版本不对整个系统所有需要glibc的进程都没法跑起来了。

重新灌系统吧。

[msg7086]

glibc被干应该就没救了。就算走console也没用。

[ivanlw]

@msg7086
@BOYPT glibc是什么东西呢？就弱弱的一个个人主机……别人怎么进得=.=

[jamesxu]

重装ssh server试试

[thedevil5032]

@ivanlw 经常有帖子讨论 VPS 主机被扫密码，里面也有一些安全对策，可以搜来看看。另外，最好是禁用密码登陆改用密钥对。
