SFTP Resume Download

See more SFTP Examples

Demonstrates how to resume an SFTP download from a previous partial download. Go

    success := false

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

    sftp := chilkat.NewSFtp()

    // Set some timeouts, in milliseconds:
    sftp.SetConnectTimeoutMs(5000)
    sftp.SetIdleTimeoutMs(10000)

    // Connect to the SSH server.  
    // The standard SSH port = 22
    // The hostname may be a hostname or IP address.
    hostname := "sftp.example.com"
    port := 22
    success = sftp.Connect(hostname,port)
    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()
        return
    }

    // Authenticate with the SSH server.  Chilkat SFTP supports
    // both password-based authenication as well as public-key
    // authentication.  This example uses password authenication.
    success = sftp.AuthenticatePw("myLogin","myPassword")
    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()

    // After authenticating, the SFTP subsystem must be initialized:
    success = sftp.InitializeSftp()
    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()

    var remoteFilePath string
    var localFilePath string

    // The ResumeDownloadFileByName method will check
    // the local file and begin downloading the remote file
    // at the appropriate point.  For example, if the local
    // file is already 215624 bytes long, it will begin downloading
    // the remote file at the 215625'th byte -- appending to
    // the local file.
