I put “rocky” for the default user but I couldn’t login through AWS. I subscribed an official Rocky Linux 9 (Official) - x86\_64 instance through AWS Marketplace. Is this default user appropriate? or Do I need to do something?? ---

Have you an SSH key uploaded to your AWS account. Indeed the user is rocky. What was the error message? Alternatively, please copy/paste the full output from: ```auto ssh -v rocky@your_aws_instance ``` and post it here. Please do not screenshot it, we need to see the full output. If nothing, then ensure that ingress for port 22 is open. ---

the command is should be something like ssh -i your.cert.pem rocky@aws-ip ---

I could do ssh login not from teraterm macro but through PowerShell. ```auto ssh -i "rocky.pem" rocky@XXX.XXX.XXX ``` To be honest, the network is fine and SSH 22 port is opening. I tried to made a web/db server instance of AWS for Rocky Linux 8.7 Version. And It was easily to do SSH login from teraterm macro with rocky user. Rocky Linux 9 is also using the same network and the same security group and the same teraterm macro as the server instance of AWS for Rocky Linux 8.7 Version. But it says that > ssh2 auto-login error user authentication failed So I still don’t know this issue come from AWS or teraterm… ```auto ;IP Address hostname = 'XXX.XXX.XXX' ;Login User username = 'rocky' ;Keyfile name keyfile = 'rocky.pem' ;key passphr ;passphr = '' ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; getdir keypath strconcat keypath '\Keys\' strconcat keypath keyfile msg = hostname strconcat msg ':22 /ssh' strconcat msg ' /auth=publickey' strconcat msg ' /user=' strconcat msg username strconcat msg ' /keyfile=' strconcat msg keypath ;strconcat msg ' /passwd=' ;strconcat msg passphr connect msg wait '$' ``` The file path. ~/keys/rocky.pem ---

What is the strength of your SSH key? Is it a 2048 RSA key? ---

If possible, try to issue your own key by using one of these: - 3072 RSA: `ssh-keygen -t rsa -b 3072` - ed25519: `ssh-keygen -t ed25519` - ecdsa: `ssh-keygen -t ecdsa` ---

Rocky 9.1 did add to “DEFAULT” crypto policy: ```auto RSAMinSize 2048 ``` Hence 2048 ought to still have been enough (unless AWS image overrides that option)? ---
