当我使用 SecureCRT 时，它会起作用

但是当我使用 MobaXterm 时，会出现权限被拒绝（公钥）的情况

我该怎么办，我更喜欢使用 MobaXterm
答案1
看来 mobaxterm 正在查看密钥的标准位置：
debug1: Trying private key: /home/liweizhou/.ssh/id_rsa
debug1: Trying private key: /home/liweizhou/.ssh/id_dsa
debug1: Trying private key: /home/liweizhou/.ssh/id_ecdsa
debug1: Trying private key: /home/liweizhou/.ssh/id_ed25519
也许您的密钥不在这些位置之一，并且您已在 secureCRT 中手动加载它，或者它正在通过其他方式发现密钥。
我将在 mobaxterm 中选择密钥，以便它会为该连接加载它。
