使用凝固汽油弹连接Cisco路由器使用SSH键无法工作

Question

我试图让netbox使用凝固汽油弹获得信任，但即使是使用凝固汽油弹的基本连接也不起作用，在密钥文件周围总是有错误，我们需要使用这个文件(不能使用密码)。

napalm==3.4.1

python=3.8

参考https://napalm.readthedocs.io/en/latest/support/上的文档，以便使用参数

我可以使用用户netbox中的~/. SSH /中的密钥直接将SSH发送到路由器

netbox@netbox:~/.ssh$ ssh -c aes128-cbc netbox@172.1.1.1
The authenticity of host '172.1.1.1 (172.1.1.1)' can't be established.
RSA key fingerprint is SHA256:<fingerprinthere>.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '172.1.1.1' (RSA) to the list of known hosts.
PHC-SW01>

提示输入密码，但失败。

如果我指定--密码''，它不会提示输入密码。如果我使用"alt_key_file“或"key_file”，则始终存在相同的错误: SyntaxError:无效语法

作为访问密钥文件的用户'netbox‘运行napalm应该是有效的。

更新:尝试在引号中插入引号re：https://github.com/napalm-automation/napalm-base/issues/309#issuecomment-461185980但没有起作用

--optional_args "hostkey_verify=False, look_for_keys=true, key_file='~/.ssh/id_rsa'"

Answer 1

通过在每个变量中放置引号，我能够使命令正常工作。

它在enable连接上失败，但是它现在使用SSH键进行连接，这就是为什么。
