(Mono C#) Inovis VAN FTP/SSL (EDI)

Demonstrates how to connect to the Inovis EDI VAN (FTP/SSL).

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

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

ftp.Hostname = "ftpssl.gateway.inovisworks.net";
ftp.Username = "myLogin";
ftp.Password = "myPassword";

// The Inovis EDI VAN requires Passive connections:
ftp.Passive = true;

// Note: The Inovis documentation mentions an outbound
// high port range of 40000-49999.  In passive mode, the
// FTP server chooses the port number for the data
// connection.  The Inovis server will choose a port number
// in the range 40000-49999.  To establish the data connection,
// your firewall must allow outgoing connections in that port
// range. 

// This tells Chilkat FTP2 to establish
// an AUTH TLS secure channel after connecting
// on the standard FTP port 21.
ftp.AuthTls = true;

// You'll probably need this property set to true if you're
// behind a NAT router or firewall.
ftp.PassiveUseHostAddr = true;

// The Ssl property is for establishing an implicit SSL connection
// on port 990.  Do not set it to true.  The Inovis VAN
// uses explicit encryption (SSL/TLS).
ftp.Ssl = false;

// The Chilkat FTP component automatically sends a "FEAT";
// command after connecting.  This allows the component
// to better know the FTP server's capabilities.
// The Invois server doesn't recognize the FEAT command,
// so disable it:
ftp.AutoFeat = false;

// Connect, convert to TLS, and login to the FTP server.
bool success = ftp.Connect();
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}
else {
    // LastErrorText contains information even when
    // successful. This allows you to visually verify
    // that the secure connection actually occurred.
    Debug.WriteLine(ftp.LastErrorText);
}

Debug.WriteLine("Connection to Inovis EDI VAN OK!");

// Do whatever you're doing to do ...
// upload files, download files, etc...

success = ftp.Disconnect();
