Dealing with ssh configuration

[marcraminv]

Hey 👋
I am trying to use the library through the ssh configuration, but I capture this error:

Caused by: net.schmizz.sshj.userauth.UserAuthException: Problem getting private key from PKCS8KeyFile{resource=[PrivateKeyFileResource] /Users/marc/.ssh/id_rsa}
at net.schmizz.sshj.userauth.method.KeyedAuthMethod.putSig(KeyedAuthMethod.java:61)

at net.schmizz.sshj.transport.Reader.run(Reader.java:59)
Caused by: java.io.IOException: unrecognised object: OPENSSH PRIVATE KEY

I have set my stfpSetting like this:

val sftpSettings: IO[SecureFtpSettings] =  IO.pure(SecureFtpSettings(
    host = "localhost",
    port = 2222,
    credentials = FtpCredentials("foo", "bar"),
    strictHostKeyChecking = false,
    knownHosts = None,
    sftpIdentity = Some(KeyFileSftpIdentity("/Users/myname/.ssh/id_rsa", None)),
    sshConfig = new net.schmizz.sshj.DefaultConfig()
  )
)

but I am not sure if I am missing something. If @regis-leray you can give me a tip, I will add it in the documentation for sure 😄

Thanks for your feedback.
So can please give more informations :

• how did you setup your ftp server
• how did you generate your ssh key
• also can you activate debug log level
• can you provide the all stacktrace ?

Also based on your exception you are getting

Caused by: net.schmizz.sshj.userauth.UserAuthException: Problem getting private key from PKCS8KeyFile{resource=[PrivateKeyFileResource] /Users/marc/.ssh/id_rsa}

i did some research on sshj and i found this issue hierynomus/sshj#437
you might need to regenerate your ssh key as suggested.
or you are might missing authorized keys hierynomus/sshj#159

thanks

[marcraminv]

Sure! Sorry to be ambiguous with the information, I start again 😄

how did you setup your ftp server
I am using this sftp docker image to up the server with this configuration for .ssh with my key

running as:

docker run -it --name ssh_test -p 2222:22 -v ~/.ssh/id_rsa.pub:/home/foo/.ssh/keys/id_rsa.pub:ro atmoz/sftp foo::1001

how did you generate your ssh key
I remember to use the same way that github recommend

can you provide the all stacktrace ?
