SSH 永远挂起？

SSH 永远挂起？

我尝试通过 SSH 连接到远程虚拟机，但该命令永远挂起。

之前，当我试图在上面设置一些东西时，我编辑了 /etc/hosts 和 /etc/init.d，我担心我可能搞砸了一些东西。如果不是很明显，那么我对网络/服务器管理方面有点陌生。

使用 -v 运行给我这个：

ssh USERNAME@IP -vvv
OpenSSH_5.9p1, OpenSSL 0.9.8x 10 May 2012
debug1: Reading configuration data /etc/ssh_config
debug1: /etc/ssh_config line 20: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to 10.150.42.39 [10.150.42.39] port 22.
debug1: Connection established.
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_rsa type -1
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_rsa-cert type -1
debug3: Incorrect RSA1 identifier
debug3: Could not load "/Users/LOCALUSERNAME/.ssh/id_dsa" as a RSA1 public key
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_dsa type 2
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_dsa-cert type -1

编辑：我尝试将 id_dsa 和 id_dsa.pub 文件移走并收到以下消息：

ssh USERNAME@IP -vvv
OpenSSH_5.9p1, OpenSSL 0.9.8x 10 May 2012
debug1: Reading configuration data /etc/ssh_config
debug1: /etc/ssh_config line 20: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to 10.150.42.39 [10.150.42.39] port 22.
debug1: Connection established.
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_rsa type -1
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_rsa-cert type -1
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_dsa type 1
debug1: identity file /Users/LOCALUSERNAME/.ssh/id_dsa-cert type -1

EDIT2：如果其他人遇到这个问题：显然我的虚拟机内存不足并挂起。我的系统管理员重新启动了它并修复了它。

答案1

事实证明，由于不相关（并且仍然有点神秘）的原因，机器不断耗尽内存。重新启动它暂时修复了它，但很快就会再次耗尽。我最终把虚拟机搞砸了，换了一个新的。
