Have been struggling for 2 nights, fighting with java for browsers (firefox and chrome) finally set up the VPN for my Ubuntu system 10.4 LTS. Find out that have some issue with chrome (after login to the vpn, there doesn’t have pop up screen, but firefox has that pop up screen with connected ip address, love firefox more than chrome!)

My Ubuntu version is: Linux agun-ubuntu 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24 09:00:03 UTC 2010 i686 GNU/Linux

  1. Install the java (jre1.6.0_23)
    1. download the jrexxx.bin
    2. chmod the jrexxx.bin to be executable (chmod a+x jrexxx.bin)
    3. copy the jrexxx.bin to the path you’re going to install java (/usr/java)
    4. ./jrexxx.bin
    5. done
  2. Enable the java for firefox (3.6.13)
    1. find the libnpjp2.so (/usr/java/jre1.6.0_23/lib/i386/libnpjp2.so)
    2. find the plugins folder for firefox (sudo find / -name “plugins” | grep “firefox”)
    3. cd to /usr/lib/firefox-3.6.13/plugins
    4. create a link to libnpjp2.so (sudo ln -s /usr/java/jre1.6.0_23/lib/i386/libnpjp2.so)
  3. Start the firefox with root privilege (sudo firefox)
  4. Login to the https://ssl.longtop.com
  5. Go to the “Network” tab
  6. Click install and accept with default option (by default will install to /usr/local/array_vpn)
  7. Done

Becareful when installing system on existing system

Leave a comment

I installing the ubuntu for my friend as following steps:

  1. make the bootable thumb drive from existing ubuntu system
  2. plug the thumb drive to the pc, and restart the computer
  3. press the F12 key
  4. select to boot from USB Storage Drive
  5. booting the ubuntu from USB
  6. select the Install option
  7. re-size the existing partition for installing the ubuntu. This step need to very very very and very careful! it’s very possible to format your existing drive!* Make sure read every single word before you click the “OK” button! I was unexpectedly select the change the existing partition size and select the format as “swap” which should not do like this, so that drive has been re-formatted! But it’s not because of ubuntu not friendly, it does prompt the warning that will ease the data from that drive, but I was too hungry to try to speed up the process, so I select the format as “swap”, then after I click “OK”, then it’s starting re-sizing the drive and formatting the used part as *SWAP*!
  8. lose data from that drive…
  9. start crying…
