installing reliance netconnect modem ZTE AC2726 in linux 2.6.26

I recently got the reliance netconnect wireless connection. I applied through their website and their response was so good. They came to my house demonstrated the speed for which i had paid and accepted. Though the representative was not a technical person he had tried to contact the technical persons of their office when i inquired about the installation of the reliance netconnect client software in linux. His colleague at the office conveyed that it cannot be installed on linux. Then i found the accompanied CD has a software which works for linux. I told the representative that to be please get informed about the software installations in linux.

The modem given to to me is ZTE AC2726.

my linux version is
$uname -a
Linux gowriganesh 2.6.26-1-686 #1 SMP

The software that comes in the accompanying CD is
ls /mnt/disk[sda5]/reliance/Linux
CrossPlatformUI-V1.0-38-RelianceHSD-i386-Ubuntu.deb
CrossPlatformUI-V1.0.38-RelianceHSD-i586-fedora.rpm
CrossPlatformUI-V1.0.38-RelianceHSD-i586-openSUSE.rpm
Reliance Netconnect - Broadband+ AC2736 Installation Guide for Linux.pdf

When installed with the above deb package it installed in the client software but was not able to detect the USB modem.

Also when tried to move to the following directories and checked for the appropriate drivers i came to know that the driver is available only for
2.6.27  2.6.28  2.6.29  2.6.30 .

Also there is a directory which says "below 2.6.27". But when compiled with that package it could n't produce the necessary driver file to insmod it for modem detection.

cd /usr/local/bin/ztemtApp/zteusbserial/
root@gowriganesh[zteusbserial]#ls
2.6.27  2.6.28  2.6.29  2.6.30  below2.6.27  README  README_EN

The USB modem is detected as USB storage medium.

Then downloaded and installed the usb-modeswitch package which is available in this website
http://packages.ubuntu.com/karmic/i386/usb-modeswitch/download

dpkg -i usb-modeswitch_1.0.2-1_i386.deb

Then Unplug and plugin the modem back. It is now detected as the modem as follows:

$lsusb
Bus 004 Device 005: ID 19d2:fff1 ONDA Communication S.p.A.

Now issued the command
modprobe usbserial vendor=0x19d2 product=0xfff1

Now in the reliance netconnect software
Add the username and password with your appropriate values that start with 93 give n in the box.

How to enable Java in Firefox 3.6+ in debian

This is note is to enable java in firefox 3.6+


When to use this note:
1. If you had installed sun jdk  from debian repository (using apt-get) firefox will not recognize the java in the system.
2. If you have directly downloaded the firefox from the mozilla website

How to:

1. The firefox 3.6 requires a plugin  libnpjp2.so. Search for the plugin:
find / -name  libnpjp2.so
you will get the answer some thing like this
/usr/lib/jvm/java-6-sun-1.6.0.12/jre/lib/i386/libnpjp2.so
(The above is the case that i had installed sun java sdk 6 in my system from the repository)
2. Now check for the profiles of mozilla firefox.
2.1.Type cd to move to home folder
2.2.  Type cd .mozilla/firefox
2.3. Type ls to list the directories. you will find a directory with extension .default. In my case it is rof0j0zs.default.
2.4. create a folder called plugins under the above found default directory
2.5. create a softlink to the above plugin in this folder. In my case ln -s /usr/lib/jvm/java-6-sun-1.6.0.12/jre/lib/i386/libnpjp2.so
 2.6. Now test your browser for java. It will work charm with all java based applications.

There is a bug in debian which results in the following error due to enabling IPV6 as default in the sysctl configuration.

load: class JavaVersionDisplayApplet.class not found.
java.lang.ClassNotFoundException: JavaVersionDisplayApplet.class
    at sun.plugin2.applet.Applet2ClassLoader.findClass(Applet2ClassLoader.java:219)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
    at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Plugin2ClassLoader.java:532)
    at sun.plugin2.applet.Plugin2Manager.createApplet(Plugin2Manager.java:2940)
    at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Plugin2Manager.java:1444)
    at java.lang.Thread.run(Thread.java:619)

To avoid please check for the following file or point to this url http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560056

1. goto /etc/sysctl.d/bindv6only.conf
2. change net.ipv6.bindv6only = 0
3. Execute invoke-rc.d procps restart
