Jan 6, 2014 - GNS3 Cisco IOS Escape Sequence

Comments

If you want to use the escape sequence in IOS in order to cancel pending commands (like a ping or a traceroute), using GNS3, and you're trying to use Ctrl+Shift+6 or Ctrl+C or any other combination that is supposed to work, as far as you can tell from the web, then just try Ctrl+6, it will probably work.

Nov 26, 2013 - JBoss ESB JMS client

Comments

In case you have followed this guide and are now wondering how to run the client, here'a a little tip to prevent you from wasting more time.


If you've created the SendJMSMessage.java inside the same project and ran it as a Java Application, then you probably got something that included this:

Caused by: java.lang.ClassNotFoundException: org.jboss.aop.metadata.ClassMetaDataLoader
or this:
Caused by: java.lang.ClassNotFoundException: org.jboss.aop.pointcut.PointcutStats
or even this:
Caused by: java.lang.ClassNotFoundException: org.jboss.aop.metadata.Pointcut

You should create a new Java Project with the SendJMSMessage.java, then go to the project properties and, instead of including every jar in the Java Build Path (as explained here), add two libraries: 1) JBoss ESB Libraries and 2) Server Runtime. The server runtime will be the previously created JBoss server runtime.

Then run this project as a Java Application and it should work.

In case your wondering what software versions I've used and so on, here are they:

  • Eclipse Helios (3.6.2);
  • JBoss Tools 3.2.x installed via Eclipse Marketplace;
  • JBoss ESB Server 4.10;
  • added JBoss Server Runtime as version 5.1;

Oct 6, 2013 - Rooting Memup SlidePad NG 808DC

Comments

After noticing there were no known methods of rooting the tablet Memup SlidePad NG 808DC (the methods for the other models did not work with this one), I took some hours off in the past 20th of July to check how hard it could be. It seems it's actually pretty easy and, finally, I'm going to post my method. Although the first root method on the web specific for this tablet, it may work for similar devices as well, but that's on your own responsibility.

The following steps assume you know how to flash a ROM to your SlidePad, as well as using ADB to get the tablet's shell.

Pre-requisites: If not already, flash the original 4.1.1 ROM provided in the french memup website: http://www.memup.net/support/fr/produit.php?id_produit=112; ADB must be installed in your computer (http://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android-debug-bridge-utility/http://pplware.sapo.pt/smartphones-tablets/android/como-usar-o-android-debug-bridge-adb/);

Step 1: Make sure /usr/xbin/su must already exists, the original 4.1.1 ROM provides it, so it's okay;

Step 2: Download http://download.clockworkmod.com/superuser/superuser.zip;

Step 3: Get the "su" binary from superuser.zip/armeabi to the SD card (/storage/sdcard0/external_sdcard);

Step 4: Enter the tablet's shell, using the command adb shell;

Step 5: Go root in the shell, using the command su;

Step 6: Backup /system/xbin/su, using cp /system/xbin/su /system/xbin/su.bak;

Step 7: Replace the system's "su" with the SD card one, using cp /storage/sdcard0/external_sdcard/su /system/xbin/su and then, chmod 6755 /system/xbin/su;

Step 8: Install Superuser APK (ClockworkMod's one) from the superuser.zip or Play Store;

Step 9: Run Superuser and let it update the "su" binary if a newer version is available;

Done!

You're welcome to ask for any clarification on the steps above.
