Cannot establish ssh tunnel aws9/8/2023 ![]() ![]() It happens that the first thing an SSH server sends to a new client is a version string, which looks like "SSH-2.0-OpenSSH_6.9" I don't know the PG protocol, but apparently your client reads the "S" in the SSH string and immediately knows it's not connected to a PG server. What is happening now is that your tunneled PG connection is going to port 4321 on the remote host, which is the SSH server. It seems you should also set the "host" on the properties tab to "localhost", but I don't know if this is required.Įrror connecting to the server: SSL error: unknown protocol expected authentication request from server, but received S Now, connect to your instance from the console. If you do, run the send-ssh-public-key command again to connect using SSH. You should set this to 5432 or whatever port your server is actually listening on. ssh -i mynewkey Permission denied (publickey,gssapi-keyex,gssapi-with-mic). The port number on the properties tab is the port that the PG server is running on. ![]() The second issue is that you have the wrong port on the Properties tab. If you don't have an id_rsa file, then you should generate a new key and keep both files this time. The point is that the private key is in foobar, while the public key is in foobar.pub.) (Key files can be named something other than "id_rsa", of course. id_rsa.pub is installed onto the server that you are connecting to, while id_rsa is used by the client that is making the connection to the server. RSA ssh keys come in two files: "id_rsa" contains the private key, while "id_rsa.pub" contains the public key. That is the file you should use as the identity file. See if you have a file in the same place named "id_rsa" without the ".pub" extension. The first issue is that this is the wrong file. I use just the same (and only) id_rsa.pub file If i use correct id_rsa file (without pub) then i get this same error: You can't start a direct SSH session into the device because the firewall blocks all inbound traffic. So tell me if you want me to provide any other info on this matter. Open a tunnel and start SSH session to remote device PDF In these tutorials, you'll learn how to remotely access a device that's behind a firewall. I'm a complete newbie to it and I may have missed something important. If i try to connect without SSH tunnel there is another error:Įrror connecting to the server: SSL error: unknown protocol expectedĪuthentication request from server, but received S Or invalid/unrecognized private key file format] [Unable to extract public key from private key file: Wrong passphrase SSH error: Authentication by identify file failed with error code -16 And this is an error that i get upon trying to connect: I use just the same (and only) id_rsa.pub file which i used to establish my ssh connection before. So what i have already done on the server is:Ĭhanged the listening port in /etc/ssh/sshd_configĮnabled remote connections in /etc/postgresql/9.3/main/pg_hba.confĪdded listening addresses in /etc/postgresql/9.3/main/nfĪnd here is my local connection settings: It must be somewhere in my Postgres connection or environment settings. My ssh connection is working so there is no problem with it. On local machine i have the same configuration. However, I cannot access the SSH tunnel (because the application running within docker, through SAM).I have a droplet on DigitalCloud with Ubuntu 14.04 and PostgreSQL 9.3. Right now I am trying out AWS Lambda with SAM and testing locally through sam local invoke This all works wonderfully when I am testing with my usual local development - locally I would point my database to localhost:6842 (random port for the ssh tunnel) I have a setup through Putty on my local machine that creates SSH Tunnel to RDS (the RDS is not public and only accessible within its network, so when I want to connect to it locally, I set up the SSH Tunnel) If you're posting a technical query, please include the following details, so that we can help you more efficiently:ĭoes this sidebar need an addition or correction?
