Demonstrates how to upload a file to an SSH server. There are no limitations on file size, and the file is streamed directly from the local filesystem.

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

loSftp = createobject("CkSFtp")

// Set some timeouts, in milliseconds:
loSftp.ConnectTimeoutMs = 5000
loSftp.IdleTimeoutMs = 10000

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.

// After authenticating, the SFTP subsystem must be initialized:
llSuccess = loSftp.InitializeSftp()

    ? loSftp.LastErrorText
    release loSftp
    return
endif

// Open a file for writing on the SSH server.
// If the file already exists, it is overwritten.
// (Specify "createNew" instead of "createTruncate" to
// prevent overwriting existing files.)
lcHandle = loSftp.OpenFile("hamlet.xml","writeOnly","createTruncate")

// -----------------------------------------------------------------------------
// This is important.  You must close the handle on the server.
// Otherwise open handles will accumulate on the server until eventually a limit
// is reached and the server will fail on a call to OpenFile.
// -----------------------------------------------------------------------------

// Close the file.
