ssh AWS ec2 bastion permission denied

When I try to connect to an EC2 in a private network through a bastion server I get this message:

<username>@<ec2-server>: Permission denied (publickey)

However, I can ssh to bastion from my local machine, and I can ssh to the EC2 from the bastion server,

Here is the .ssh/config I'm using:

Host <ec2-servers>*
    IdentityFile ~/.ssh/id_rsa
    User <username>

Here is the command I use to ssh:

ssh -J <bastion-server> <ec2-server>

Note: Permissions are good (700 for ~/.ssh/ and 600 for ~/.ssh/*)

Thanks in advance for your help!

Solution

  • Fixed it by adding local ssh public key in the authorized_keys of the remote ec2 instance.
