Re: Tramp no longer connects to aws instances

[Frederick Bartlett]

That's what I thought, but I don't understand why ...

Here's your shell experiment (same result as from inside Emacs):

$ ssh -l ec2-user  -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none xx.xxx.xxx.xxx

address@hidden: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

And here's my usual ssh command (which works):

ssh -i <path_to_public_key_file> -o ServerAliveInterval=5 -o ServerAliveCountMax=1 address@hidden

The ip address shows up in ~/.ssh/known_hosts as

xx.xxx.xxx.xxx ecdsa-sha2-nistp256 <key>

Does that provide any clues?

There is a vpn active on my system, but connections to aws aren't routed through it (so far as I can tell).

Could I edit the Tramp command in Emacs to include a reference to public key?

Thanks,

Fred

Yes, that's the problem (also visible in Tramp's debug buffer). Your
remote host seems to have a problem with your public key.

Could you pls check the command Tramp has sent, in a shell terminal? The
command is

# ssh -l ec2-user  -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none xx.xxx.xxx.xxx

How do you call ssh in a shell manually?
