在服务器上的/ var / log / secure中我看到了这一点(幸运的是我仍然打开了一个会话)：

May 21 10:27:31 host1 sshd[12387]: Accepted publickey for user from 1.1.11.239 port 34135 ssh2
May 21 10:27:31 host1 sshd[12387]: pam_unix(sshd:session): session opened for user user by (uid=0)

所以没有明显的错误.客户端和服务器似乎能够进行通信. / var / log / messages中没有任何内容.

充足的磁盘空间.安装了一些路径(包括家庭区域),但我仍然活跃的shell可以访问它们.

我可以连接到其他服务器;只有这一个有问题.我试过重启sshd. sshd的配置文件看起来像默认配置文件,因此没有任何内容.据我所知,最近没有任何变化.

尝试运行命令(ssh host1 -t bash或-t vi)似乎也挂起,所以不要认为它与我的登录脚本有任何关系.

还尝试从同一位置和其他位置的其他主机登录,或通过Putty从Windows登录,并使用密码而不是密钥登录.

不知道在哪里可以看到或者还有什么可以尝试.

这是一个64位的RHEL 6.4服务器.
