Copy files over SCP with Go
=============================
[](https://goreportcard.com/report/bramvdbogaerde/go-scp) [](https://godoc.org/github.com/bramvdbogaerde/go-scp)
This package makes it very easy to copy files over scp in Go.
It uses the golang.org/x/crypto/ssh package to establish a secure connection to a remote server in order to copy the files via the SCP protocol.
### Example usage
```go
package main
import (
"fmt"
scp "github.com/bramvdbogaerde/go-scp"
"github.com/bramvdbogaerde/go-scp/auth"
"golang.org/x/crypto/ssh"
"os"
"context"
)
func main() {
// Use SSH key authentication from the auth package
// we ignore the host key in this example, please change this if you use this library
clientConfig, _ := auth.PrivateKey("username", "/path/to/rsa/key", ssh.InsecureIgnoreHostKey())
// For other authentication methods see ssh.ClientConfig and ssh.AuthMethod
// Create a new SCP client
client := scp.NewClient("example.com:22", &clientConfig)
// Connect to the remote server
err := client.Connect()
if err != nil {
fmt.Println("Couldn't establish a connection to the remote server ", err)
return
}
// Open a file
f, _ := os.Open("/path/to/local/file")
// Close client connection after the file has been copied
defer client.Close()
// Close the file after it has been copied
defer f.Close()
// Finally, copy the file over
// Usage: CopyFromFile(context, file, remotePath, permission)
// the context can be adjusted to provide time-outs or inherit from other contexts if this is embedded in a larger application.
err = client.CopyFromFile(context.Background(), *f, "/home/server/test.txt", "0655")
if err != nil {
fmt.Println("Error while copying file ", err)
}
}
```
#### Using an existing SSH connection
If you have an existing established SSH connection, you can use that instead.
```go
func connectSSH() *ssh.Client {
// setup SSH connection
}
func main() {
sshClient := connectSSH()
// Create a new SCP client, note that this function might
// return an error, as a new SSH session is established using the existing connecton
client, err := scp.NewClientBySSH(sshClient)
if err != nil {
fmt.Println("Error creating new SSH session from existing connection", err)
}
/* .. same as above .. */
}
```
#### Copying Files from Remote Server
It is also possible to copy remote files using this library.
The usage is similar to the example at the top of this section, except that `CopyFromRemote` needsto be used instead.
For a more comprehensive example, please consult the `TestDownloadFile` function in t he `tests/basic_test.go` file.
