Setting Environment Variables for SCP Transfers

See more SCP Examples

Demonstrates how to set remote environment variables for an SCP transfer.

Note 1: This example requires Chilkat v9.5.0.79 or greater.

Note 2: Setting environment variables for SCP is only supported by some SSH servers.

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();

// First connect to an SSH server.
success = ssh.Connect("example.com",22);
if (success != true) {
    Debug.WriteLine(ssh.LastErrorText);
    return;
}

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

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

// After 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);
if (success != true) {
    Debug.WriteLine(scp.LastErrorText);
    return;
}

// Specify the environment variables to be set in JSON as follows.
// This example sets two environment variables.  One is named "LCS_PASSWORD" and the other "MY_TEST_NAME".
Chilkat.JsonObject jsonEnvVars = new Chilkat.JsonObject();
jsonEnvVars.EmitCompact = false;
jsonEnvVars.UpdateString("LCS_PASSWORD","secret");
jsonEnvVars.UpdateString("MY_TEST_NAME","abc");
string strEnvVars = jsonEnvVars.Emit();

Debug.WriteLine(strEnvVars);

// Setting the SendEnv property causes Chilkat to set each environment variable on the SSH server
// prior to doing the upload or download.
scp.SendEnv = strEnvVars;

// Do the upload..
string remotePath = "starfish.jpg";
string localPath = "qa_data/jpg/starfish.jpg";
success = scp.UploadFile(localPath,remotePath);
if (success != true) {
    Debug.WriteLine(scp.LastErrorText);
    return;
}

Debug.WriteLine("SCP upload file success.");

// Disconnect
ssh.Disconnect();
