I have 50 something Linux machines (RHEL). I want to run some commands on these machines from a go script running on a central machine. I have setup password-less ssh authentication to all of them from the central machine to all the remote machines. Though I'm open to non-ssh solutions too, though something secure is preferred.

The commands being run would change over time. I would also want to process the output and return codes of commands being run on the remote machines in my script running on central machine.

I only found this ssh package, which supports only password authentication method, which is not good enough.

Any other options?

    You can use public keys with the go.crypto/ssh package using PublicKeys.

    There's a detailed example in the repo around line 114.

    Another example using ssh agent @ https://github.com/davecheney/socksie/blob/master/main.go.

    You just can use this package https://github.com/hypersleep/easyssh

    For example you can call ps ax remotely:

    package main
    import (
    func main() {
        ssh := &easyssh.MakeConfig {
            User: "core",
            Server: "core",
            Key: "/.ssh/id_rsa",
            Port: "22",
        response, err := ssh.Run("ps ax")
        if err != nil {
            panic("Can't run remote command: " + err.Error())
        } else {
