KDE 4.22

If you are looking for gparted for KDE, or qtparted for KDE:

Look for "partitionmanager"

Kubuntu:

sudo apt-get install partitionmanager

Fedora:

su
yum install partitionmanager

I had a very hard time trying to figure out how to send "CTRL+A" to a Telent session through Java. (for an AS/400 telnet session).


First obstacle was finding what the key mapping was. I found this on midrange.com. "CTRL+A maps to "Escape, A". [link]

Using TelnetWrapper library here: [link]
I found the Escape Key value here: [link]

What confused me at first was the use of the word "Escape" in the Telnet specification. There are special escaped keys that would normally use the TelnetProtocolHandler's sendTelnetControl(byte code) function. This is not the case. Here's how I did it:

TelnetWrapper t = new TelnetWrapper();
t.connect(hst, prt);
t.waitfor("User . . . . . . . . . . . . . .");
t.send(user + "\t" + pwd);
byte[] b = new byte[] {'\033', 'a'};
t.write(b);
System.out.println(t.waitfor(""));

For Gnome Users:
System --> Preferences --> Keyboard
Layouts Tab --> Layout Options
Alt/Win Key Behavior --> Left Alt is swapped with Left Win

For KDE 4.x Users:
System Settings --> Regional and Language
Keyboard Layout --> Layout Tab --> Enable Keyboard Layouts
Advanced Tab --> Alt/Win key behavior --> Left Alt is swapped with Left Win

This will swap your ALT key with the WINDOWS key (also called "Super", "Apple" or "Command"). This is useful for a person who Alt+Tab's on a PC but has since switched to macintosh hardware and is not accustomed to the Macintosh keyboard layout.

If you are not using a macintosh keyboard, this *should* have the opposite effect and make a PC keyboard ALT+TAB like a Mac.

I never thought to look in the locale settings for KDE, so this took me quite a while to find. Hope it helps others.

This works on Ubuntu 8.10, Ubuntu 9.04, Kubuntu 9.04. (Intrepid, Jaunty). This should work for both KDE and gnome respectively. Hope this saves some people some time.

I've used FamFamFam's CreativeCommons Silk icon set for a while and I've made a few of my own. Here they are for others to share, hosted on Blogger/Picasa and mirrored on ImageShack.

I am trying to assign a setDefaultCellRenderer(..., ...) to my NetBeans projects and all of the answers keep steering me back to "Table Contents --> Columns --> Renderer" and then I am stuck.

I was working from this guide and quickly noticed it had no effect on my NetBeans JTable!!! I've been using this guide in non-NetBeans projects with success, but now using the NetBeans IDE it fails. Am I doing something wrong?

First of all, there's quite a few people asking this same question:

http://www.coderanch.com/t/345011/Swing-AWT-SWT-JFace/java/Customize-JTable-NetBeans-GUI-Builder


This quick article shed some light on the class types, but chaning my setDefaultRenderer(..., ...) to "String.class" didn't fix it.

So I've updated the nabble post with some of my attempts. No answers yet. Any help appreciated:

"java.sql.SQLException: Descriptor index not valid."

If you are running an SQL query (in this case with Java) against an AS/400 and get the above message, try replacing the code in your resultset loop. Find the line that looks like this:

rs.getString(0)

And replace with lines like this:

rs.getString("PFNMCN");

Notice, the records is being retrieved by name instead of by index. Alternately, you can try:

rs.getString(1);

The underlying problem is resultset indexes start at [1] instead of [0]. This is confusing as most Java indexes start counting at 0. Hope this helps. What the message should probably say is "resultset index is out of bounds for the returned set". But jt400 is a free driver, so we can live with that message. :)

Also note, that if you do "SELECT PFNMCN AS FIRSTNAME...", then your code should read:

rs.getString("FIRSTNAME");

This java error message can be confusing at first, but it is a very quick fix!

I've decided to use the UnixLoginHanlder class. Here's my sample code s, and below is the history of my struggles.

Socket s = new Socket(host, port);
UnixLoginHandler handler = new UnixLoginHandler(s);
TelnetInputStreamConsumer is = handler.doLogin(user, pass);

String command="echo hello > deleteme.tres\r\n";

pw = new PrintWriter(new OutputStreamWriter(s.getOutputStream()), true);

pw.print(command);
// Don't forget to flush

pw.flush();

// Executing these immediately may precede the commands.
// Do logout/disconnects on a seperate event
//handler.doLogout();

//handler.disconnect();

Good luck!

This article will illustrate my struggles with automating some Telnet functions through Java. The application that's being designed could provide as an interface or relay server, and is intended eventually to get some information out of some flat files on an IBM AIX Unix server.

Disclaimer: Yes I'm aware of the security issues around the Telnet protocol. No, SSH is not available currently on this server.

In short, I'm trying to get a simple telnet session working through a Java Socket connection. Some examples, like this one make it seem as simple as making a new Socket and sending some text through. Naturally, I wouldn't be writing this article if it were that simple. Methods like "readline()" return arbitrary characters like "ÿþ%ÿý", and there's not much documentation around what this all means, so instead of spending more time re-inventing the wheel, I've begun evaluating 3rd party APIs.

A quick Google search shows some APIs with tutorials, but costs money. I'm skipping those for now, since I'm just in the design phase of this interface, so I'm sticking to free ones for now. The closer to GPL the better, right?

Forums allude that the Apache project has a great implementation of the Telnet protocol. My experience with the Apache libraries are they are often interdependent on each other, and I'd like to make this interface as small and vanilla as possible. I've found three potential candidates: JTA Telnet for Java, sadun-utils UnixLoginHandler and Dieter Wimberger's telnetd2. Telnetd2 does not come pre-compiled to drop-in as an API and also doesn't provide any code-snippets or documentation with its download, so going to skip that for now as well.

My unsuccessful code snippets are below attached exactly as they appeared in outgoing emails. As authors respond, I'll post their messages as well. If I have success, I'll certainly post that too.

Hi.

My name's Tres and I've been trying to use JTA as an API in an
application for implementing a simple Telnet connection.

I tried the sample code in /jta26/de/mud/telnet/

TelnetWrapper's
javadoc, and it connects and does a log-in first try, however I'm
having a hard time getting any further, such as executing commands on
the remote host.

I'm in Windows XP JDK 1.6 connecting to AIX 5.2. If I run the JAR as
an application it works just like PuTTY and acts as expected, so I'm
sure its something that I'm doing wrong in the code.

Is there a mailing list or perhaps a person to contact with this?
Also, are there any special considerations when connecting to Korn
shell or AIX? Thanks!

-Tres

p.s. I've attached the sample TelnetWrapper code below which has been
copied from the javadoc.

/**
* TelnetWrapper telnet = new TelnetWrapper();
* try {
* telnet.connect(args[0], 23);
* telnet.login("user", "password");
* telnet.setPrompt("user@host");
* telnet.waitfor("Terminal type?");
* telnet.send("dumb");
* System.out.println(telnet.send("ls -l"));
* } catch(java.io.IOException e) {
* e.printStackTrace();
* }
*/
