the authenticity of host '' can't be established.

This message usually appears when you are trying to connect via SSH to a remote server for the first time. It means that the server's public key is not recognized by your computer, and you need to verify its authenticity before proceeding.

To do this, you can compare the fingerprint of the server's public key with the one provided to you by the server administrator. If they match, you can proceed with the connection by typing "yes" when prompted. If you are unsure or suspicious about the fingerprint, you should not proceed with the connection and contact the server administrator for further instructions.

The authenticity of host can't be established.

"The authenticity of host can't be established"是一个在使用SSH远程连接宿主机时可能出现的提示。该提示是由于SSH客户端检测到宿主机的公钥发生了变化或者是第一次连接宿主机时出现的。这个提示是为了确保连接的安全性，以防止中间人攻击。提示中的"authenticity"指的是宿主机的真实性和可信度。提示中的"can't be established"表示无法确定宿主机的真实性。在这种情况下，SSH客户端会显示宿主机的公钥指纹，以供用户检查和确认是否连接到正确的宿主机。用户可以选择接受或拒绝连接。如果用户选择接受，客户端会将宿主机的公钥添加到已知主机列表中，以便以后的连接。如果用户选择拒绝，连接将被终止。 这个提示是为了确保连接的安全性，以防止中间人攻击。提示中的"authenticity"指的是宿主机的真实性和可信度。提示中的"can't be established"表示无法确定宿主机的真实性。在这种情况下，SSH客户端会显示宿主机的公钥指纹，以供用户检查和确认是否连接到正确的宿主机。用户可以选择接受或拒绝连接。如果用户选择接受，客户端会将宿主机的公钥添加到已知主机列表中，以便以后的连接。如果用户选择拒绝，连接将被终止。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

The authenticity of host 'git.nevint.com (10.88.17.5)' can't be established.

回答: 这个问题涉及到SSH连接时的主机认证。当你第一次连接一个主机时，SSH会提示你确认主机的真实性。这个提示是为了确保你连接的是你预期的主机，而不是一个恶意的主机。在你的问题中，提示显示了主机名和IP地址，即'git.nevint.com (10.88.17.5)'。这个提示意味着你正在连接到这个主机，并且SSH无法验证这个主机的真实性。为了确认主机的真实性，你可以检查主机的公钥指纹是否与你预期的一致。你可以通过其他安全渠道获取主机的公钥指纹，比如联系主机管理员或查看主机的文档。一旦你确认了主机的真实性，你可以选择接受主机的公钥并将其添加到你的已知主机列表中，这样以后连接时就不会再出现这个提示了。
