Supermirco IPMI KVM: remote connection without webbrowser

Question

I try to connect with the IPMI remote connection(KVM) without the use op the webbrowser or IPMIview tool. But so far no luck.

The first think that I did is launching the "jviewer.jnlp" with javaws. This file will be created by the IPMI website if you push the "Remote Connection" button. This solution works until the web session is closed. I try to replace the encrypted argument with the username and password. But somehow there is session id embedded.

jviewer.jnpl file:

<?xml version="1.0" encoding="UTF-8"?>

<jnlp spec="1.0+" codebase="https://192.168.99.201/Java">

The argument username and password replacement will work if the jnlp is named as "launch.jnlp" Some Supermicro IPMI version will use a different structure.

Second I try to connect with the IPMIview tool version 2.9.32. That work so the connection is ok. Know I try the connect by using the jars of the IPMIview. Replace the host with the IPMI IP

java -Djava.library.path=. -jar iKVM.jar host ADMIN ADMIN null 5900 2623 2 0

This will open the remote connection but gives a "Connection failed" error.

java -Djava.library.path=. -jar JViewerX9.jar host ADMIN ADMIN

Also the same result: Connection failed The connection failed comes with a warning box. On OK is closed the application

Some IPMI info:

A cold reset "ipmitool mc reset cold" also does not work.

I hope that someone knows what the argument mean for the jnlp file or the someone has a working solution for this problem

Edit: I try the answer of Maxim Akristiniy and came up with the following code:

public class IpmiRemoteViewer {

    public static void main(String[] args)
            throws FailingHttpStatusCodeException, MalformedURLException,
            IOException {

        String username = "ADMIN";
    String password = "ADMIN";
    String ip = "192.168.99.150";

    final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_17);

    webClient.getOptions().setThrowExceptionOnScriptError(false);
    webClient.getCookieManager().setCookiesEnabled(true);

    webClient.getOptions().setUseInsecureSSL(true);
    webClient.getOptions().setJavaScriptEnabled(true);

    if (!forms.isEmpty()) {

        HtmlForm form = forms.get(0);
        HtmlSubmitInput button = (HtmlSubmitInput) form.getInputsByValue(

        webClient.waitForBackgroundJavaScript(500);

        // Do it again
        form = page2.getForms().get(0);

        // username
        textField = form.getInputByName("T1");
        textField.setValueAttribute(username);

        // password
        textField2 = form.getInputByName("T2");
        textField2.setValueAttribute(password);

        ScriptResult scriptResult = page2.executeJavaScript("DoLogin();");

        // Print the index.html page
        System.out.println(scriptResult.getNewPage().toString());

        // Print the session id
        for (Cookie cookie : webClient.getCookieManager().getCookies()) {
            if (cookie.getName().equals("SessionCookie")) {

                System.out.println("Session id = " + sessionId);
            }
        }

        // Download the jviewer.jnlp file
        Page page5 = webClient.getPage("http://" + ip
                + "/Java/jviewer.jnlp?EXTRNIP=" + ip + "&JNLPSTR=JViewer");
        WebResponse response = page5.getWebResponse();
        InputStream inputStream = response.getContentAsStream();

        writeToFile("viewer.jnlp", inputStream);
    }

}

protected static void writeToFile(String filename, InputStream inputStream) {
    OutputStream outputStream = null;

    try {

        File file = new File(filename);

        // write the inputStream to a FileOutputStream
            outputStream = new FileOutputStream(file);

            int read = 0;
            byte[] bytes = new byte[1024];

            while ((read = inputStream.read(bytes)) != -1) {
                outputStream.write(bytes, 0, read);
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (inputStream != null) {
                try {
                    inputStream.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if (outputStream != null) {
                try {
                    outputStream.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }

            }
        }
    }

}

Only now it will write the login page in the viewer.jnlp file. Still no luck. I managed to read the index.html page that is behind the login page. But the session is closing very fast.

Answer 1

Download the jviewer.jnlp file but first login.

#!/bin/sh

USER=ADMIN
PASS=ADMIN
HOST=192.168.99.150

COOKIE=`curl --data "WEBVAR_USERNAME=$USER&WEBVAR_PASSWORD=$PASS" http://$HOST/rpc/WEBSES/create.asp 2> /dev/null | grep SESSION_COOKIE | cut -d\' -f 4`
curl --cookie Cookie=SessionCookie=$COOKIE http://$HOST/Java/jviewer.jnlp -o $HOST.jviewer.jnlp

Then start the jviewer.jnlp file with javaws
