I decided to try out the Laravel Forge, but I'm having trouble with the SSH keys. I use digitalocean.com for the VMs and have used SSH keys with success many times before.

However when I paste my public key into Forge (which adds it to the server) I'm not able to connect to it. I use Putty and I get the following error:

Disconnected: No supported authentication methods available (server sent: publickey)

Key was generated using puttygen and was added to pageant.

I have tried using the very same key files as my other VM and tried creating a new one, but all without luck.

I'm hoping someone can help me out here.

Edit: here is my putty log http://pastebin.com/ZGmm8Mcv

  • I don't know the putty equivalent but you need to show the output of ssh -vvv. "No Supported authentication methods available" sounds like no public key was sent when trying to connect. Commented May 31, 2014 at 14:48

  • Event Log: Trying Pageant key #0 Event Log: Server refused public key - looks like a clear case of the offered key not being accepted. I doubt using laravel forge fundamentally changes how ssh access works - you should IMO debug it like any other ssh access problem (check keys exist on the server, check they match the key being offered).

The answer from @alysdal worked perfectly for me. Just to have the steps on this site as well:

You have to modify your public key and transform your generated key from this form

---- BEGIN SSH2 PUBLIC KEY ---- Comment: "rsa-key-20160907" AAAAB3NzaC1yc2EAAAABJQAAAIEA3nfXA8oSOGcx1OJg0/2dkgH2gDXhN6GX5/QW KyPif8tHYh/GBvwsnoLyPAUNq9D9wv/g+DxBr1nGpIwIAICxycHNEq7iNGcImhWs rlEWBWRE8fYG4Qpx0/CKDcNsCZzjiu0exwp4pw5nDcZQOsr321bly3edRgfgmgix rzLaOCk= ---- END SSH2 PUBLIC KEY ----

into this form

ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEA3nfXA8oSOGcx1OJg0/2dkgH2gDXhN6GX5/QWKyPif8tHYh/GBvwsnoLyPAUNq9D9wv/g+DxBr1nGpIwIAICxycHNEq7iNGcImhWsrlEWBWRE8fYG4Qpx0/CKDcNsCZzjiu0exwp4pw5nDcZQOsr321bly3edRgfgmgixrzLaOCk= user@host

which means:

  1. Remove first two lines and the last line.
  2. Join the remaining lines into one single line without whitespaces
  3. Insert ssh-rsa with one trailing space at the beginning of the file
  4. Optional: You can append <user>@<host> at the end of the file preceded with a whitespace.

Turns out putty and openssh have incompatibilities. I modified my ssh key according to they following guide and it now work seamlessly.
