Skipping private key with passphrase without chance to enter it

[aronjanosch]

Hi,

I'm currently not able to use mole because it just skips my key, because it says its passphrase protected.

Affected Version

2.0.0

Expected Behavior

Either asking for a passphrase or using the apple keychain when UseKeychain yes is present in the config.

Current Behavior

It just skips the authentication using key -> connection does not establish.

Steps to Reproduce

Here is my ssh config:
.ssh/config

Include config.d/*

Host *
  IgnoreUnknown UseKeychain

Host server0
  HostName 1.2.2.2
  User username
  IdentityFile ~/.ssh/id_ed25519

.ssh/config.d/test

Host *
  IgnoreUnknown UseKeychain,AddKeysToAgent
  UseKeychain yes
  AddKeysToAgent yes

Host server1
  HostName 1.2.3.3
  User user
  Port 22
  IdentityFile ~/.ssh/id_ed25519_test
  ProxyCommand ssh -W %h:%p server0
  ForwardAgent yes

And here is the command I used + Output. There servers get correctly identified from the config.
I think the problem is that for the jumphost (server0) I use a different ssh key without passphrase. For server1 I use a ssh key with passphrase.

mole start local \
    --source :5601 \
    --destination 1.2.3.4:5601 \
    --server server1

ERRO[0000] error starting mole                           error="error generating ssh client config: at least one working authentication method (key or ssh agent) must be present."

I hope you can help
