connect: Network is unreachable

So suddenly I was getting this weird error. Don’t know the exact reason. But some forum says it may happens because of having multiple NICs.

Anyway, then I checked $ sudo netstat -nr

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
10.10.10.0      0.0.0.0         255.255.255.0   U         0 0          0 eth0

then run the following command

$ /sbin/route add -net 0.0.0.0 gw 10.10.10.1 eth0

and this time the result was different

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
0.0.0.0         10.10.10.1      0.0.0.0         UG        0 0          0 eth0
10.10.10.0      0.0.0.0         255.255.255.0   U         0 0          0 eth0

….tada!!! It started working!

Installing Vim from source in Ubuntu

Vim can be easily found in Synaptic Package Manager. But sometimes that is the oder version. Like I need Vim 7.3 where the available version in synaptic package manager is 7.2. Then I thought I should go for the source file available on the site. I downloaded the file and tried to run as the site said. But it was showing some errors. Then I googled again to get some more idea. I found a simple process. Which says four steps after going to the vim directory:
1. ./configure
2. make
3. sudo make install
4. sudo ln -s /usr/local/bin/vim /usr/bin/vim (process 4 is optional)
But then I got a new error message telling me something like these You need to install a terminal library: for example ncurses. Or specify the name of the library with –with-tlib
This particular error informs us that we need an additional dev library to compile the file.
To get the library simply type:

sudo apt-get install libncurses5-dev

Then follow the four simple steps mentioned earlier in the post.
Now new version of Vim should be installed in your system.

gnome-keyring password ubuntu

After my latest setup of ubuntu 10.04, I was facing problem with the keyring password access whenever I was accessing yahoo on Empathy.

To change gnome-keyring password graphically

Places ==> Home Folder

then, ctrl+h to view the hidden files.

.gnome2 ==> keyrings

delete the the file default.keyring
next time when you’ll try anything like that, it’ll ask for new password.

to keep backup of the original file
mv ~/.gnome2/keyrings/default.keyring ~/.gnome2/keyrings/default.keyring.bak

synaptic/update manager update in ubuntu 10.04

Even if I’m trying to update with update manager or apt, synaptic is not updating. I faced this weired problem in ubuntu 10.04.
There is a very simple solution to get rid out of this problem.
Just execute this command in your terminal.

sudo gedit /etc/apt/sources.list

remove the line which contains CD/DVD ROM and the next line (if any, without starting with #)

update again with

sudo apt-get update

If you are no too unlucky you are already done with updating. enjoy 😀

Installation on ubuntu 10.04

install/execute/run .sh file
.sh is a shell script. To run this kind of script go to terminal and type ./filename.sh

extraxt .tar.gz file

sudo tar xvfz package.tar.gz -C /opt
x –> extract
v –> list what is extracting(verbose)
f –> specifies the file to use
