What did you do?

~/go/src$ gomote create plan9-arm
# host type "host-plan9-arm-0intro" is not elastic; 2 of 1 machines connected, 2 busy
# canceled a post-submit build on a machine of type "host-plan9-arm-0intro"; it should reconnect and get assigned to you
…
~/go/src$ gomote ssh --i-will-not-break-the-host user-bcmills-plan9-arm-0

What did you expect to see?

A successful SSH connection to a builder for the plan9/arm platform.

What did you see instead?

$ ssh -p 2222 mutable-user-bcmills-plan9-arm-0@farmer.golang.org # auth using https://github.com/bcmills.keys
Enter passphrase for key '/usr/local/google/home/bcmills/.ssh/id_rsa':
# Welcome to the gomote ssh proxy, bcmills.
# Connecting to/starting remote ssh...
#
# `gomote push` and the builders use:
# - workdir: /boot/workdir
# - GOROOT: /boot/workdir/go
# - GOPATH: /boot/workdir/gopath
# - env: GO_BUILDER_NAME=plan9-arm
# Happy debugging.
# Plan9 user/pass: glenda/glenda123
# Failed to get IP out of "pi4g": <nil>
Connection to farmer.golang.org closed.

Have you succeeded to connect to the plan9-386 builder?

I didn't try plan9-386 due to #42117.

It's likely you will hit the same issue as the one described in #42117, once the current issue will be fixed.

Please try again after CL 414595, so we could see the proper error message.

internal/coordinator/remote: fix log message in legacyIncomingSSHPost…

…Auth and IncomingSSHPostAuth

In the Plan 9 case, a log message is printed when ipErr != nil,
but the wrong variable err was displayed instead of ipErr.

Updates golang/go#53571

Is gomote ssh supposed to work on builders running outside of GCE?
Running gomote ssh on an external builder would require it to be accessible from Internet and knowledge of the authentication credentials.

Yes.

Running gomote ssh on an external builder would require it to be accessible from Internet and knowledge of the authentication credentials.

I believe that gomote ssh is supposed to tunnel the SSH connection over the buildlet's existing reverse connection. (@cagedmantis and @golang/release could fill you in with more details.)

Would it be possible to obtain access to farmer.golang.org, so I could run gomote on my side?
