This state is thenĮxposed to you via the Session interface. Processed, responded to, and any relevant state is updated. Variables, requesting PTY, and changing window size. This package automatically handles basic SSH requests like setting environment Server's behavior is by creating a custom Server: Log.Fatal(ssh.ListenAndServe(':2222', nil, ssh.HostKeyFile('/Users/progrium/.ssh/id_rsa')))Īlthough all options have functional option helpers, another way to control the It's a better idea to generate or point to an existing key on your system: This is convenientĮxcept you'll have to deal with clients being confused that the host key is different. If you don't specify a host key, it will generate one every time. Handler is usually nil, which means to use DefaultHandler. ListenAndServe starts an SSH server with a given address, handler, and options. Relevant types and some functions from crypto/ssh. You should be able to build any SSH server using only this package, which wraps The goal of the API was to make it as simple as using net/http, so Package ssh wraps the crypto/ssh package with a higher-level API for building Roadmapīecome a sponsor and get your logo on our README on Github with a link to your site. Pull requests are welcome! However, since this project is very much about APIĭesign, please submit API changes as issues to discuss before submitting PRs.Īlso, you can join our Slack to discuss as well. ExamplesĪ bunch of great examples are in the _examples directory. This package was built by after working on nearly a dozen projects at Glider Labs using SSH and collaborating with (known for ssh-chat). Net/http, so the API is very similar: package main The goal of the API was to make it as simple as using The Glider Labs SSH server package is dope. If not, you would have to setup a tunnel.DefaultSessionHandler(srv, conn, newChan, ctx)ĭirectTCPIPHandler(srv, conn, newChan, ctx) You might be able to pass that connection into db library. The last line above is not exactly tunneling, but an TCP connection open to DB server. Below is not a tested sample without error checking: var buffer byteīuffer, err = ioutil.ReadFile(sshKeyFile)Ĭonn, err := ssh.Dial('tcp', endpoint, sshConfig)ĭbConn, err = conn.Dial('tcp', dbEndpoint)

GOLANG SSH TUNNEL HOW TO

There are tutorials out there how to use GO ssh tunneling.

GOLANG SSH TUNNEL CODE

If external client works, then you can attempt to put it all into go language code without external SSH client. You can accomplish #1 and #2 with ssh client like OpenSSH or putty.

establish tunnel from local port to remote db port.

I have not tested postgre this way, but I have had this model used in some proprietary server connections.

So, this answer about SSH tunneling to DB machine. I don't know if a native postgre ssh tunneling support exists. It is my understanding that you need to open connection to postgre database. CLI that returns a pointer to a sql.DB connection.ĭb, err := sql.Open('postgres', getDbInfo())ĬheckErr(err, 'Unable to connecto tthe DB')ĭbInfo += fmt.Sprintf('dbname=%s ', dbName)ĭbInfo += fmt.Sprintf('dbname=%s ', 'development')ĭbInfo += fmt.Sprintf('dbuser=%s ', 'user')ĭbInfo += fmt.Sprintf('dbpass=%s ', dbPass)ĭbInfo += fmt.Sprintf('sslmode=%s', sslMode) ConnectDb is a short cut function that takes parameters through

pem key, and I'm not quite sure how to do this w/o forcing a connection unsecured package main I can connect locally no problem, but I cannot connect to the remote easily. I'm not sure how to accomplish this task.
