Demonstrates how to open a text file on the SSH server and read text.

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

Chilkat.SFtp sftp = new Chilkat.SFtp();

// Set some timeouts, in milliseconds:
sftp.ConnectTimeoutMs = 5000;

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

// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.

// After authenticating, the SFTP subsystem must be initialized:

// Open a file for reading.

// Assume the file we are reading contains the following text:
// abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
// (in ANSI format -- i.e. one byte per char).

// Read 26 bytes:
