SCP Upload Contents of String to Remote File

See more SCP Examples

Demonstrates how to upload the contents of a string variable using the SCP protocol (Secure Copy Protocol over SSH). The text is uploaded to a file in specific remote directory. If the file did not already exist, it is created. If it already existed, it is overwritten. Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // Connect to an SSH server:
    var hostname string
    var port int

    // Hostname may be an IP address or hostname:
    hostname = "www.some-ssh-server.com"
    port = 22

    success = ssh.Connect(hostname,port)
    if success != true {
        fmt.Println(ssh.LastErrorText())
        ssh.DisposeSsh()

    // Wait a max of 5 seconds when reading responses..
    ssh.SetIdleTimeoutMs(5000)

    // Authenticate using login/password:

    // as the underlying transport in our SCP object.

    // optionally include a BOM can be specified in this way.

    // utf-8 representation, including the BOM at the start of the file.
