我使用 Mac Yosemite OS 通过 ssh 连接到我的办公室服务器。我无法通过任何 Wifi 连接（我的公寓的 wifi 或我工作场所的 wifi）。但是，当我通过以太网连接时，我能够执行 ssh。我做了以下事情来解决问题，但没有成功。
- 我关闭了防火墙但仍然无法连接。
我 ping 了我的服务器，并得到了
Request timeout状态。但是，当我通过我的其他服务器 ping 或 ssh 时Mac（搭载 Maverick OS），我能够得到我的 ping 消息的积极响应并且连接上（如果有任何 wifi）。我执行了 ssh -vvv 用户名@主机，收到了以下消息
OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 100: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to <server name> [<server ip address>] port 22. debug1: connect to address <server ip address> port 22: Operation timed out ssh: connect to host <server name> port 22: Operation timed out我重新安装了 OpenSSL，但仍然无法解决问题。
- 当我使用 Cyberduck、Firezilla 或 VNC 时也遇到了类似的问题，但我的另一台装有 OS Maverick 的计算机没有出现这种情况。
您有什么想法或建议可以让我尝试吗？谢谢！
******更新 1******
我删除了 OpenSSL 和 brew，并尝试连接到服务器。我做到了
ssh -vvv uname@<server-name>
该消息表明连接已建立。但是，出现以下消息后我无法继续操作：
debug1: SSH2_MSG_SERVICE_ACCEPT received

另外，当我尝试执行 ping 时，我可以执行此操作并能够收到消息而没有错误！
我认为我已经非常接近解决方案了，并且确定 brew 在我的 mac yosemite 上无法正常工作。
********更新 2**********
我能够通过以下方式解决问题：
- 去除酿造
基本上给出 UseDNS 的论点为否
vi /etc/sshd_config 使用DNS
服务 sshd 重新启动
取消设置 SSH_AUTH_SOCK
然后执行 ssh
