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. C#

bool success = false;

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

Chilkat.Ssh ssh = new Chilkat.Ssh();

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

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

success = ssh.Connect(hostname,port);
if (success != true) {
    Debug.WriteLine(ssh.LastErrorText);
    return;
}

// Wait a max of 5 seconds when reading responses..
ssh.IdleTimeoutMs = 5000;

// Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword");
if (success != true) {
    Debug.WriteLine(ssh.LastErrorText);
    return;
}

// Once the SSH object is connected and authenticated, we use it
// as the underlying transport in our SCP object.
Chilkat.Scp scp = new Chilkat.Scp();

success = scp.UseSsh(ssh);

// See https://www.chilkatsoft.com/p/p_463.asp for a list of valid charsets.
string charset = "utf-8";

// This uploads to the "uploads/text" directory relative to the HOME
// directory of the SSH user account.  
// Note: The remote target directory must already exist on the SSH server.

// prefix the charset name with "bom:".  Any charset that can 
// optionally include a BOM can be specified in this way.

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