camel-ssh 基于密钥的身份验证

Question

我正在尝试通过骆驼路线执行 ssh 命令。我在下面 错误任何人都可以帮助我解决问题。我可以使用用户名和密码来执行命令。

我在服务器的授权密钥中复制的公钥。 我正在使用蓝图 dsl。

 < to uri="ssh://admin@10.23.24.41:22? certResource=classpath:test_rsa&amp;timeout=5000"/>

test_rsa 是公钥所在的文件名。

Answer 1

我忘记在类路径中添加 test_rsa 作为私钥和 test_rsa.pub。添加后，我就可以与服务器通信了。

Answer 2

而不是 certResource=classpath:test_rsa， 试试：privateKeyFile=/path/to/test_rsa

您的 known_hosts 文件最初可以为空。 这对我有用。希望这会有所帮助！
