SSH Client failed to connect using private key

Questions / Help

I’m trying connect to ssh server using custom location (not in ~/.ssh) private key

key = File.open!("/private/tmp/.ssh/id_rsa")
known_hosts = File.open!("/private/tmp/.ssh/known_hosts")

cb =
  SSHClientKeyAPI.with_options(
    identity: key,
    known_hosts: known_hosts,
    silently_accept_hosts: true
  )

# IO.inspect(cb)

context =
  SSHKit.context("x230.local",
    port: 22,
    user: "username",
    key_cb: cb,
    #password: "pass",
  )

SSHKit.run(context, "whoami")

But get result:

16:34:28.579 [notice] Erlang SSH :client version: 5.0.1 (OpenSSL 1.1.1s  1 Nov 2022).

I also try using :ssh.connect but got same result.

Note:

  • I can connect using password authentication
  • I can connect with key using ssh cli ssh username@host -i /private/tmp/.ssh/id_rsa
