Handshake failed error #60

BLucky-gh · 2022-04-20T18:53:05Z

When trying to connect to any server I'm receiving an error:
something went wrong:failed to create session: connection failed: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

I'm running wishlist in local tui mode, the config file is as follows (edited for privacy)

IdentityFile 	~/.ssh/id_rsa

Host		github.com
  AddKeysToAgent yes
  IdentityFile	~/.ssh/id_ed25519

Host 		*.mydomain.tld
  IdentityFile 	~/.ssh/id_rsa

Host 		foo
  HostName	x.x.x.x
  User		bar
  Port		222

Host 		baz
  HostName	y.y.y.y
  User		root
  Port		1774

Note: the public keys are confirmed to work normally, issues only arise when connecting through wishlist

The text was updated successfully, but these errors were encountered:

anything else in the wishlist.log file?

also, which of these endpoints you tried to connect and failed?

BLucky-gh · 2022-04-26T12:30:04Z

2 ) all of them

1 ) where are the logs located?

caarlos0 · 2022-04-26T12:38:28Z

1 ) where are the logs located?

should be in the folder in which you executed wishlist

2 ) all of them

my guess is that its the same thing that happens here: charmbracelet/soft-serve#48 (comment)

BLucky-gh · 2022-04-26T12:43:22Z

here's the logs

by the way the mitm/key mismatch error is not wishlist's fault I think, since I do occasionally get that error with regular ssh connecting to that host (which is github)

2 ) all of them

my guess is that its the same thing that happens here: charmbracelet/soft-serve#48 (comment)

is that the one where the go library that charm uses can't handle rsa keys?

caarlos0 · 2022-04-26T13:01:58Z

is that the one where the go library that charm uses can't handle rsa keys?

the root cause is x/crypto: golang/crypto#197

logs did not help much, we'll see if I can add more info to them...

meanwhile, can you try

ssh -v git.charm.sh

using the same key? if it is the rsa thing, this should confirm it...

hmmm so I guess I need to add more logs, thanks for the feedback so far, will look into it

caarlos0 · 2022-04-26T13:53:29Z

ah, I think I get it.. you have a SSH agent running, but it doesnt have a key that's accepted...

if so, #61 should fix it

BLucky-gh · 2022-04-26T13:55:29Z

ah, I think I get it.. you have a SSH agent running, but it doesnt have a key that's accepted...

Not sure what you mean, running ssh-add -L shows that the key in question is indeed in the agent

BLucky-gh · 2022-04-26T13:57:04Z

#61 might help with some of them (the ones that do have a key specified), but for the ones where the key is not specified and where I just let it use the key from my ssh-agent, I don't think it would help

caarlos0 · 2022-04-26T15:10:11Z

#62 adds more logs

Cordelya · 2022-06-09T16:33:05Z

I may be encountering the same or a similar issue - with two specific endpoints that both use the same key, which is a different key than the one most of my other ssh endpoints use.

using $HOME/.wishlist/config.yaml
running wishlist as local
most of my endpoints have agent forwarding off and use a key named "id_rsa"; they all connect fine that way
issue appears to be that the remote servers in question are being presented with the wrong key ("id_rsa" is being presented; the correct key is a different one)
I have a soft-serve server in my endpoints list that also uses a manually-generated key that is not named "id_rsa" and that connection works fine w/o agent forwarding
workaround for the two servers that are being passed the wrong key is to specify agent forwarding and have an ssh-agent set up and ready to go with the key - then it works.

I've examined the example config.yaml several times and it doesn't appear to include any endpoint params for specifying which key to use for an endpoint.

Hmm, I guess we could allow the identityfiles option in yaml as well

will work in a pr for it
