Usage:

You can see ssh, scp, ProxyCommand on examples folder.

ssh

See example/ssh/ssh.go

package main

import (
	"fmt"
	"time"

	"github.com/appleboy/easyssh-proxy"
)

func main() {
	// Create MakeConfig instance with remote username, server address and path to private key.
	ssh := &easyssh.MakeConfig{
		User:   "appleboy",
		Server: "example.com",
		// Optional key or Password without either we try to contact your agent SOCKET
		//Password: "password",
		Key:     "/.ssh/id_rsa",
		Port:    "22",
		Timeout: 60 * time.Second,
	}

	// Call Run method with command you want to run on remote server.
	stdout, stderr, done, err := ssh.Run("ls -al", 60)
	// Handle errors
	if err != nil {
		panic("Can't run remote command: " + err.Error())
	} else {
		fmt.Println("don is :", done, "stdout is :", stdout, ";   stderr is :", stderr)
	}

}

scp

See example/scp/scp.go

package main

import (
	"fmt"

	"github.com/appleboy/easyssh-proxy"
)

func main() {
	// Create MakeConfig instance with remote username, server address and path to private key.
	ssh := &easyssh.MakeConfig{
		User:     "appleboy",
		Server:   "example.com",
		Password: "123qwe",
		Port:     "22",
	}

	// Call Scp method with file you want to upload to remote server.
	// Please make sure the `tmp` floder exists.
	err := ssh.Scp("/root/source.csv", "/tmp/target.csv")

	// Handle errors
	if err != nil {
		panic("Can't run remote command: " + err.Error())
	} else {
		fmt.Println("success")
	}
}

SSH ProxyCommand

See example/proxy/proxy.go

	ssh := &easyssh.MakeConfig{
		User:    "drone-scp",
		Server:  "localhost",
		Port:    "22",
		KeyPath: "./tests/.ssh/id_rsa",
		Proxy: easyssh.DefaultConfig{
			User:    "drone-scp",
			Server:  "localhost",
			Port:    "22",
			KeyPath: "./tests/.ssh/id_rsa",
		},
	}
