Permission denied to connect to Amazon EC2 using SSH at Windows 8

amazon-ec2, amazon-web-services, git, ssh, windows

Solution

After several tries, I found an article with some instructions here https://serverfault.com/questions/194567/how-do-i-tell-git-for-windows-where-to-find-my-private-rsa-key

I followed these steps: "After you have the home directory, and a .ssh folder under that, you want to open PuTTYgen and open the key (.ppk file) you have previously created. Once your key is open, you want to select Conversions -> Export OpenSSH key and save it to HOME.ssh\id_rsa. After you have the key at that location, Git bash will recognize the key and use it"

Problem

I'm starting using Amazon EC2 service. I have installed an Amazon Linux instance, set the PEM file, opened the SSH ports and installed a GIT service. My local environment it's Windows 8. Through putty and WinSCP I can connect without problems. I have followed the docs and converted my PEM file to a PPK and everything works fine. The problem is when I try to do a git push from my local machine. I always get a "permission denied (public key)" when I try to connect. I have made a ssh-add to PEM file using the git bash, generated a custom key trough the GIT Bash and added this key to the key pars at the EC2 Instance and nothing works... If I try (using git bash) a ssh -i and specify the PEM file, I have a connection. ``` ssh -i c:/[PATH]/[PEM-FILE].pem ec2-user@[HOST].compute.amazonaws.com ``` If I try without -i, no connection. ``` $ ssh ec2-user@[HOST].compute.amazonaws.com Permission denied (publickey). ``` Here follows the trace with -vT command: ``` ssh -vT ec2-user@[HOST].compute.amazonaws.com OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Connecting to [HOST].compute.amazonaws.com [54.201. 110.48] port 22. debug1: Connection established. debug1: identity file [PATH]/Usuario/.ssh/identity type -1 debug1: identity file [PATH]/Usuario/.ssh/id_rsa type 1 debug1: identity file [PATH]/Usuario/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.2 debug1: match: OpenSSH_6.2 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '[HOST].compute.amazonaws.com' is known and ma tches the RSA host key. debug1: Found key in [PATH]/Usuario/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: [PATH]/Usuario/.ssh/identity debug1: Offering public key: [PATH]/Usuario/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: [PATH]/Usuario/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). ``` So, there's a way to connect via SSH without the -i option?
