    Subject: handshake problem? (fwd)

Sorry, should have enclosed some code. I realize I'm not dealing with
certificates, but I note on the server side that the server certificate is
not even being sent before the connection is closed.
[and thanks very much for your prompt response on my last question].

import javax.net.*;
import javax.net.ssl.*;
import com.sun.net.ssl.*;
import java.security.*;

public class https_test {
public static void main(String[] argv) {

Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
String hostname = argv[0];
int port = Integer.parseInt(argv[1]);
SSLSocketFactory f = (SSLSocketFactory)SSLSocketFactory.getDefault();
SSLSocket connection = null;
try {
connection = (SSLSocket)f.createSocket(hostname,port);
} catch(java.net.UnknownHostException unknown) {
unknown.printStackTrace();
} catch(java.io.IOException io) {
io.printStackTrace();
}
EndHandshakeListener h = new EndHandshakeListener();
connection.addHandshakeCompletedListener(h);

String[] suites = {"SSL_RSA_WITH_NULL_MD5"};
connection.setEnabledCipherSuites(suites);
connection.setUseClientMode(true);
connection.setNeedClientAuth(false);
String[] enab = connection.getEnabledCipherSuites();
System.out.println("Enabled: " + enab[0]);
String[] pp = connection.getSupportedCipherSuites();
for (int i = 0;i<pp.length;i++) {
System.out.println("Supported suite: " + pp[i]);
}
SSLSession sess = connection.getSession();
System.out.println("Enabled cipher suite: " + sess.getCipherSuite());
System.out.println("Last Accessed time: " +
sess.getLastAccessedTime());
try {
connection.startHandshake();
}catch(java.io.IOException io2) {
io2.printStackTrace();
}
}
}

Subject: handshake problem?

Any ideas what could be causing the following handshake problem... it
seems better error messages would be in order. Thanks, Helen
