SSH 挂起，不提示输入密码

刚刚重新安装了 OS X，出于某种原因，我现在无法通过 SSH 连接到本地网络上的特定计算机。我可以毫无问题地通过 SSH 连接到网络上的其他计算机，其他计算机也可以通过 SSH 连接到有问题的计算机。

我不确定从哪里开始寻找问题 - 有人能指出我正确的方向吗？以下是连接尝试的转储：

OpenSSH_5.1p1, OpenSSL 0.9.7l 28 Sep 2006

...此时它会挂起一段时间，然后恢复...

答案1

逗我开心——

在 /etc/hosts 中为您无法连接的主机之一添加条目（即..

 10.0.0.17 Franky

如果这不起作用，请尝试编辑你的 ~/.ssh/config

并添加

 host *
 PreferredAuthentications publickey,password

GSS 是一种 kerberos 实现——而且它似乎要么找不到可以将主机放入的域，要么只是需要被告知；哟；不要那样做。

答案2

我刚刚发现在 gentoo 上运行的 ssh 客户端 OpenSSH_6.0p1lpk、2012 年 5 月 10 日的 OpenSSL 1.0.1c 与在 debian 上运行的服务器 OpenSSH_5.5p1 Debian-6+squeeze2、2010 年 6 月 1 日的 OpenSSL 0.9.8o 存在同样的行为。

就我而言，解决方法是删除客户端上的 hpn 支持并重新编译它。

答案3

虽然该线程有点旧，但将 GSSAPIAuthentication no 添加到我的 .ssh/config 文件中可以解决我的密码提示挂起问题。

答案4

我假设您经过所有延迟后仍能成功登录。请将其放入您的~/.ssh/config文件中：

Host *
    GSSAPIAuthentication no
