我正在使用Mac Yosemite OS通过ssh连接到我的办公室服务器。我无法连接任何Wifi（我的apt的wifi或我的工作场所的wifi）。但是，当我通过以太网连接时，我能够做ssh。我做了以下事情来解决问题，但我没有成功。
- 切断我的防火墙，但我仍然无法连接。
我抓住了我的服务器而且我得到了
Request timeout状态。然而，当我通过我的另一个ping或ssh时 Mac（拥有Maverick OS） ，我能得到我的ping消息的积极响应并连接（如果有任何wifi）。我做了ssh -vvv username @ host，我收到了以下消息
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，仍然无法解决问题。
- 当我使用Cyberduck，Firezilla或VNC时，我遇到了类似的问题，但是我的其他计算机没有OS Maverick。
你有任何我应该尝试的想法或建议吗？谢谢！
******更新1 *******
我删除了OpenSSL＆amp; brew并尝试连接到服务器。我做到了
ssh -vvv uname@<server-name>
消息说连接已建立。但是，在以下消息之后，我无法继续前进：
debug1: SSH2_MSG_SERVICE_ACCEPT received

此外，当我尝试ping时，我能够做到并且能够接收消息而不是错误！
我认为我非常接近解决方案，并且肯定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
基本上将UseDNS的参数设为no
vi / etc / sshd_config UseDNS没有
服务sshd重新启动
取消设置SSH_AUTH_SOCK
然后做ssh
traceroute主机告诉你什么？你说你在端口22上的imp ping和tcp都有超时。这表明存在连接问题。只连接到wifi时可以使用互联网吗？

嗨@Paul - 我运行了traceroute＆lt;服务器名称＆gt;我没有收到任何错误消息。它跑了64跳，显示收到了数据包。我试过通过我的公寓的wifi和以太网电缆使用互联网。我不知道为什么我的Yosemite在我的Mac上有连接问题，但其他一个工作正常。
