Hello, I'm trying to disable password auth for SSH and enable key authentication. I created user green-set keys in cpanel user ssh->manage keys and authorized the key. If I use a remote terminal to connect: ssh -i /Users/user_remote/.ssh/id_rsa green-set@host68.remote-server-domain-123.net -p 2222 The server does have a non-standard SSH port of 2222. I get this error in my remote terminal: user_remote@Coconut % ssh -i /Users/user_remote/.ssh/id_rsa green-set@host68.remote-server-domain-123.net -p 2222 kex_exchange_identification: read: Connection reset by peer Connection reset by 123.456.789.123 port 2222 user_remote@Coconut Desktop % Why would the remote server reset the connection for key auth and allow password? Thanks, Mike

  Hi, check if there any ssh connection blocking from the firewall or the connection is being blocked due to the Host-Based Access Control Lists in hosts.deny try restarting SSH server.

  Thanks, I checked there were not blocks. I did find an extra ALLOW at the end of my host entry in the hosts.allow file. After that I disabled password auth and the key auth started to work.

  I'm glad you were able to track that down!
