I found a way to install the adobe flash plugin on my ubuntu box. Till now I was trying to install the .deb package from the adobe site which is named as (ubuntu 8.04+ ) and it alway got installed but never worked! So here’s a way:
Done! 
It took some time but I managed to configure the Idea Netsetter wireless USB plug and surf device on my Ubuntu laptop. It wasn’t as tough as I had thought. Here’s the procedure:
Step 1. Write the following in your /etc/wvdial.conf file, save and close:
[Dialer Defaults]
Modem=/dev/ttyUSB0
Baud = 460800
Init 1 = AT+CGMM
Init 2 = AT+CMEE=1
Init 3 = ATE0
Init 4 = AT^HS=0,0
Init 5 = AT+CFUN?
Init 6 = AT+CLCK=”SC”,2
Init 7 = AT+CPIN?
Init 8 = AT+CLCK=”SC”,2
Modem Type = USB MODEM
Phone=*99#
Username = idea
Password = idea
Dial Command=ATDT
Stupid Mode=1
ISDN=0
APN = internet
Step 2. Add the following lines to your /etc/network/interfaces file:
iface ppp0 inet ppp
provider ppp0
auto ppp0
It would look something like this (only the encircled part is important):
Step 3. Restart the network services by the following command:
$ sudo /etc/init.d/networking restart
Step 4. Go to System-> Administration -> Network. You’d see something like this:
Uncheck the ‘Wired’ connection (disable it). Now go to the properties of Point to point connection do the following settings in the respective tabs:
[GENERAL]:
[MODEM]:
[OPTIONS]
Step 5. Again restart the network connection (step 3).
Step 6. Plug in your Idea Netsetter in one of the USB ports and run the following command in your terminal:
$ sudo wvdial
That’s it .. if everything’s fine wvdial would show your new Local and Remote IP address for the idea connection.
Have fun.
Friends this is a simple command I use whenever I edit my conkyrc file:
$while true; do conky -q -i 10; sleep 3; done
Starting conky this way kills it and restarts it after every 3+10*n seconds, where n is the update interval mentioned in your conkyrc file. So, you can open ~/.conkyrc file in your editor run the above command. You would see the changes on the conky right on your desktop as it is restarted again and again. (please dont forget to keep saving the file as you edit it to make this thing work).
By the way, I have edited a conkyrc file i found on a webiste and finetuned it !! My conky is simply amazing now I’d post the file in my next post (and a snapshot of my desktop).
Today, somehow the network of my college got reconfigured or something, and all subnets got changed hostel wise. Hence, the network wasn’t being accessed by the old IP addresses. Now, in the earlier versions of Ubuntu (before Intrepid) it was relatively easy to change the static IP addresses from the Network Manager in the panel, but Intrepid onwards, this intreface has been changed and I had been wondering for a while how to do it. Now, today, since it was an absolutely desperate situation, I finally figured a way out.
Solution:
Open the file /etc/network/interfaces in your favourite editor:
$ sudo gedit /etc/network/interfaces
You would find something like this:
auto lo
iface lo inet loopback
iface eth0 inet static
address 10.4.1.41
netmask 255.0.0.0
auto eth0
If you don’t find the last 4 lines in this file, then your network configuration is set to dynamic IP. So, add these four lines to the end of this file. And, if your see these lines, it means your have previously set your IP address to static. Now, to change your static adderss, change the address given below the line ‘iface eth0 static’ (here, 10.4.1.41)to whatever address u want.
Finally, restart the networking service by the command:
$sudo /etc/init.d/networking restart
Verify the change by the command:
$ip addr
You would see the new IP address in the eth0 section!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now, I stumbled upon this solution when I was checking out the man pages of ‘ip’ and related commands and then I tried the command for restarting the network. When it didn’t work, I opened the file /etc/init.d/networking and found that that the script uses the files in the /etc/network directory. There I found the file named ‘interfaces’ and upon opening it, I knew this was what I was searching for!
I had some problems installing the Netbeans IDE 6.5 on Ubuntu Intrepid. After running the file netbeans-6.5-python-linux.sh in the terminal, there was an error:
net beans lexical error or unexpected token, expected valid token
If you are facing similar problems, refer to earlier post :
JAVA Swing and AWT applications freezing in Ubuntu
The solution to this problem is the same as mentioned in the above post. Though I had been using Netbeans 6.1, the configuration had changed somehow! Anyways, after following the instructions, the problem should get solved.
Happy Netbean-ing ..
Well, I saw many people having problem with Thunderbird not wrapping text at the default set 72 chars. Huh, I figured out the solution. The edit/options >preferences > composition > general tab has an entry box saying
“wrap plain text messages at __ characters”
the default set is 72 characters. Now what happens is that most of the mails that we send are HTML or ‘unknown’ by default. And the entry box says “plain text” not HTML. So, go to the most frequently mailed addresses in your addressbook in thunderbird and select ‘plain’ text message as the default in the contact details for each. it was not a problem, it was just obvious !!
I installed the LAMP + phpmyadmin combo yesterday on my Ubuntu Intrepid machine for hosting a local website.
But later I realized that the phpmyadmin page, though password protected, was visible throughout my local network! So, to disable remote access to phpmyadmin , add the following code to the end of your /etc/apache2/apache2.conf file ..
# Disabling phpmyadmin for remote access
<directory>
Order Deny,Allow
Deny from all
Allow from localhost
</directory>
Now I had been facing this problem from quite some time, but recently found a quick solution. Well, by default, the system uses GIJ as the Java byte interpretor and possibly, it causes the applications to freeze. I had installed the sun-java-6 jdk package but it was not functional because gij was the default one.
Steps:
1. Install the sun-java6-sdk package.
2. Find the default jvm being used by your machine by typing: java -version
3. In case it shows ‘gij’, then type: sudo update-alternatives –config java
It would list all the possible options with a number corresponding to each. For me it shows:
There are 5 alternatives which provide `java’.
Selection Alternative
———————————————–
1 /usr/bin/cacao
* 2 /usr/lib/jvm/java-6-sun/jre/bin/java
3 /usr/lib/jvm/java-1.5.0-sun/jre/bin/java
4 /usr/bin/gij-4.3
+ 5 /usr/lib/jvm/java-gcj/jre/bin/java
Press enter to keep the default[*], or type selection number:
4. Type in the corresponding number to java-6-sun/jre/bin/java, and press return.
That’s all… unsure the version of java again by typing th command in step 2, hopefully you will see something different
You might have come across the ‘no sound’ problem after a fresh installation of Ubuntu 8.10 Intrepid. Well, there are a couple of solutions around and this one worked for me :
1. Go to System -> Administration -> Users and Groups
2. Click on ‘Unlock’ and enter password.
3. Next, go to ‘Manage Groups’.
4. Search for the groups ‘pulse’ and ‘pulse access’
5. For both of these, double click on them and add yourself to this group by checking on the check-box.
6. Hopefully, you are done !! Logout with ctrl+alt+backspace, and login again.
