通过ssh登录到我的一台服务器时，它仅在身份验证后挂起。这是带有的客户端输出-v。

在/var/log/secure服务器上，我看到了这一点（幸运的是，我仍然有一个打开的会话）：
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)
因此，没有明显的错误。客户端和服务器似乎能够通信。没事/var/log/messages。
足够的磁盘空间。已安装一些路径（包括家庭区域），但是我仍然处于活动状态的Shell可以访问它们。
我可以连接到其他服务器；只有这个有问题。我尝试重新启动sshd。的配置文件sshd看起来像默认文件，所以里面没有文件。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）似乎也挂起了，因此不要认为与我的登录脚本有关。
还尝试过从同一位置和其他位置的其他主机登录，或者通过Putty从Windows登录，然后使用密码而不是密钥登录。
不知道在哪里看或尝试什么。
这是64位RHEL 6.4服务器。
我要做的第一件事是删除所有用户登录脚本，以确保。
