Connection Refused - VirtualBox

[akloster]

I am trying to connect via ssh to a virtualbox. I have set up the vm to accept password and key authentication. The access is via port forwarding, e.g. localhost port 2222 to port 22 inside the guest machine.

Logging in via port 2222 works from bash, both with password and key file.

Using spur does not work. I am getting a "111: Connection refused".

I began using the original simple examples from the readme, then proceeded to try various things as mentioned in #2 .

Any further ideas?

Thank you for your time.

Could you paste in the code you're using to invoke spur, and the manual command from bash that's successful?

[akloster]

Python code:

shell = spur.SshShell(hostname="localhost", port=2222, username="MASKED", private_key_file="MASKED")
with shell:
    result = shell.run(["echo", "-n", "hello"])
    print result.output

and ssh user@localhost -p 2222

Have you tried using "127.0.0.1" instead of "localhost" for the hostname?

Can you grab the traceback from the "Connection refused" error? Something similar to the following should do the trick:

import spur
import spur.ssh

try:
    shell = spur.SshShell(
        hostname="localhost",
        port=2222,
        username="MASKED",
        private_key_file="MASKED"
    )
    with shell:
        result = shell.run(["echo", "-n", "hello"])
        print result.output
except spur.ssh.ConnectionError as error:
    print error.original_traceback
    raise

Actually, with 127.0.0.1 it works. But it's strange that this would work, while the other works only with 22, not with 2222.

Here are the tracebacks:

Actually, with 127.0.0.1 it works.

I've hit the same issue, but I'm not entirely sure what causes it. Regardless, it sounds like things are working, so I'll close the issue.
