Hi Cafe! This is not actually a question about Haskell, but it is related. I sent my request and I have now an account in community.haskell.org. When I was going to use my project, I read these instructions: http://community.haskell.org/admin/using_project.html But I stopped in the first step "If you need to use a shell, SSH to community.haskell.org". OK, I don't have too knowledge in SSH, so I searched the web and found "putty" as an SSH client. I downloaded it and tried it. But, sadly, without success. I put this configuration: Host name: community.haskell.org Port: 22 Connection type: SSH And it connects! Then, server asks me for an user name, and, after I put my user name, it throws the following error: "Disconnected: No supported authentication methods available (server sent: publickey)." Uhmmmm... I have no idea of how to avoid this error. Wrong client? Wrong configuration? Well, I have a public key I didn't put anywhere yet (but in the community registration). I guess I'm lacking some authentication, but I don't know how to solve it. I hope someone can give me some pointers! Thanks in advance! And sorry if this is not a strictly-related Haskell question.
