go-scp makes it easy to copy files/folders between two hosts over SSH. It uses the golang.org/x/crypto/ssh package to establish a secure connection with the remote host and transfers files via the SCP protocol.
package main
import (
"golang.org/x/crypto/ssh"
"net"
)
var (
addr = "192.168.0.102:22"
user = "root"
password = "password"
)
func main() {
cfg := &ssh.ClientConfig{
Config: ssh.Config{},
User: user,
Auth: []ssh.AuthMethod{
ssh.Password(password),
},
HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error {
return nil
},
}
scp, err := New(addr, cfg)
checkErr(err)
defer scp.Close()
err = scp.Upload("testdata", "/root/scp")
checkErr(err)
err = scp.Download("/root/scp", "testdata")
checkErr(err)
}
func checkErr(err error) {
if err != nil {
panic(err)
}
}
