SSH on Windows

[a.aly]

So at first I tried to log into the Colosseum gateway but got this error "No supported authentication methods available (server sent: publickey)".

I couldn't figure out what was wrong until I discovered that I was incorrectly posting my SSH public key into my Colosseum account.  

Using Puttygen, I created a key and saved the public key, then copied it from the saved text file. This is incorrect.

I should have copied the generated public key directly from Puttygen into Colosseum SSH key page.

Just wanted to share this in case someone had the same/similar issue. I was able to successfully log-in using Putty on Windows 10.
