我已将 Mac 升级到 Mountain Lion。现在升级已完成，我无法通过 SSH 连接任何服务器超过几秒钟，也无法接收任何 SSH 连接。
我只能假设升级过程中的某些因素导致了此问题。我该怎么做才能诊断错误并修复它？我想使用用户名连接到其他系统jjasonclark，并希望其他人使用用户名连接到我的系统remotepair。
我没有关于 ssh 的任何日志/var/log/system.log。我没有名为 的文件/var/log/secure.log。并且grep通过syslog -d /var/log/aslssh 只会显示我编辑/etc/sshd_config文件的那些时间。
当其他人尝试连接我（使用该-vvv选项）时，他们的客户端将挂起此消息。

解决了！
解决这个问题的方法很奇怪。原来我需要重置我的 PRAM。它肯定存储了一些升级后需要更改的详细信息。
苹果有一个关于如何重置 PRAM 的文章。重新启动并按住+++cmd直到第二次听到“a” 。optpr
