我试图做一个Ansible ping ansible ansible all -m ping --ask-pass但是我得到SSH失败。 由于debugging日志是相当广泛的，我已经把下面的报价减less到了我认为问题发生的地方。 在日志之前，我可以连接到远程主机（一个无头RHEL5虚拟机），但实际执行“ping”时，会失败，出现下面的错误。

我通过传统的SSH连接到主机，然后检查xterm是否在远程盒上运行，并在安装时运行。 它运行，但炸弹与以下错误：
xterm Xt error: Can't open display: xterm: DISPLAY is not set
我的直觉是，SSH连接，试图运行的命令，然后不能因为XTT炸popup来。 我一直在寻找一种方法来改变使用哪个terminal，但在文档中找不到任何东西。 任何input或build议，非常感谢。
在撰写本文时，在Windows上运行Cygwin中的Ansible有点奇怪。 不知道它是什么，但它不是我能修复的东西。 我切换到Linux虚拟机，事情已经开始正常工作。
我用了两个小时的search引擎来处理奇怪的错误，使用了以下的设置：
cat /etc/ansible/ansible.cfg [defaults] host_key_checking = False
可能对安全性不好…还有：
cat /etc/ansible/hosts [dbservers] 56.77.50.151 ansible_ssh_port=22 ansible_ssh_user=ssh_user
校验：
ansible -vvvv all -a "/bin/echo hello"
我必须确保公共的私钥validationconfiguration正确
cat id_rsa.pub >> ~/.ssh/authorized_keys cat ~/.ssh/authorized_keys chmod 0600 ~/.ssh/authorized_keys ls -al ~/.ssh/authorized_keys rm -fv ~/id_rsa.pub
我会怀疑cygwin上组和用户的configuration的转折点：和chown -v local_pc_user：local_pc_user〜/ .ssh / id_rsa.pub
最后的输出是：

这种行为在一些Ansible更新之后开始。 在较旧的Ansible版本中，我没有任何问题。 这似乎是xterm，这是问题。 为什么Ansible需要运行xterm？ 我将它列为Ansible中的一个bug。
无论如何，我通过在~/.ssh/config添加以下内容来解决Cygwin中的问题：
