I tried the perform the following:

k3sup join --ip 192.168.1.217 --server-ip 192.168.1.199 --user suhr

got the error:
Error: unable to connect to (server) 192.168.1.199:22 over ssh: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

on the server, I see that:
Mar 23 01:03:15 suhr-dt sshd[13518]: Connection closed by authenticating user suhr 192.168.1.217 port 39384 [preauth]

Why do you need this?

Just trying to set up k3s for learning purpose.

Expected Behaviour

I expect this to create an agent and connect to server

Current Behaviour

It complains about some ssh error

Possible Solution

Steps to Reproduce

Your Environment

server is kubuntu 20.04 on x86_64; trying to connect from Raspberry pi4

  • k3sup version:
k3sup version
  • What Kubernetes distribution, client and server version are you using?
kubectl version

  • What OS or type or VM are you using for your cluster? Where is it hosted? (for k3sup install/join):

  • Operating System and version (e.g. Linux, Windows, MacOS):

uname -a

cat /etc/os-release

Hi @flatironnyc

You probably need to specify the server user:

k3sup join \
  --ip 192.168.1.217 \
  --server-ip 192.168.1.199 \
  --user suhr \
+  --server-user suhr

Make sure that you've also run ssh-copy-id and have the username correct for the remote server.

If suhr is the user on your local machine and on the server and on the agent, then you shouldn't need that flag.
