gosshtool

hey guys, this repo is a fork of github.com/scottkiss/gosshtool but original repo has some bug. So I fork it and fix some issues. Beside this I have add go mod for this repo. So I can be easy for use. ssh tool library for Go,gosshtool provide some useful functions for ssh client in golang.implemented using golang.org/x/crypto/ssh.

supports

• command execution on multiple servers.
• ssh tunnel local port forwarding.
• ssh authentication using private keys or password.
• ssh session timeout support.
• ssh file upload support.

Installation

go get -u github.com/lzhaoyang/gosshtool

Examples

command execution on single server

    package main
    import (
        "github.com/lzhaoyang/gosshtool"
        "log"
    )
    func main(){
        sshconfig := &gosshtool.SSHClientConfig{
                User:     "user",
                Password: "pwd",
                Host:     "11.11.22.22",
            }
        sshclient := gosshtool.NewSSHClient(sshconfig)
        log.Println(sshclient.Host)
        stdout, stderr,session, err := sshclient.Cmd("pwd",nil,nil,0)
        if err != nil {
            log.Fatal(err)
        }
        log.Println(session)
        log.Println(stdout)
        log.Println(stderr)
    }
    

command execution on multiple servers

    package main
    
    import (
        "github.com/lzhaoyang/gosshtool"
        "log"
    )
    
    func main(){

        config := &gosshtool.SSHClientConfig{
        		User:     "sam",
        		Password: "123456",
        		Host:     "serverA", //ip:port
        	}
        gosshtool.NewSSHClient(config)
    
        config2 := &gosshtool.SSHClientConfig{
            User:     "sirk",
            Privatekey: "sshprivatekey",
            Host:     "serverB",
        }
        gosshtool.NewSSHClient(config2)
        stdout, _,_, err := gosshtool.ExecuteCmd("pwd", "serverA")
        if err != nil {
            log.Fatal(err)
        }
        log.Println(stdout)
    
        stdout, _,_, err = gosshtool.ExecuteCmd("pwd", "serverB")
        if err != nil {
            log.Fatal(err)
        }
        log.Println(stdout)

    }
	

ssh tunnel port forwarding

package main

import (
	_ "github.com/go-sql-driver/mysql"
	"github.com/scottkiss/gomagic/dbmagic"
	"github.com/lzhaoyang/gosshtool"
	//"io/ioutil"
	"log"
)

func dbop() {
	ds := new(dbmagic.DataSource)
	ds.Charset = "utf8"
	ds.Host = "127.0.0.1"
	ds.Port = 9999
	ds.DatabaseName = "test"
	ds.User = "root"
	ds.Password = "password"
	dbm, err := dbmagic.Open("mysql", ds)
	if err != nil {
		log.Fatal(err)
	}
	row := dbm.Db.QueryRow("select name from provinces where id=?", 1)
	var name string
	err = row.Scan(&name)
	if err != nil {
		log.Fatal(err)
	}
	log.Println(name)
	dbm.Close()
}

func main() {
	server := new(gosshtool.LocalForwardServer)
	server.LocalBindAddress = ":9999"
	server.RemoteAddress = "remote.com:3306"
	server.SshServerAddress = "112.224.38.111"
	server.SshUserPassword = "passwd"
	//buf, _ := ioutil.ReadFile("/your/home/path/.ssh/id_rsa")
	//server.SshPrivateKey = string(buf)
	server.SshUserName = "sirk"
	server.Start(dbop)
	defer server.Stop()
}
