Fedora for beginners

0 comments Posted by Suganthi at 9:05 AM Labels:

I was using Ubuntu and Windows in my laptop for a long period of time. As we are behind a proxy in college and when I go home, I had to change the settings often. So I used ubuntu only when I went home. At a point of time, I very badly wanted to quit windows.
Though I like ubuntu, I had a special attraction towards fedora. I installed fedora 11 in my laptop on 1st Nov,2009. Now my laptop has only Fedora.
It took one full day to set my laptop to use. ie, to access net, additional packages like unrar, flash etc.
I think there will be many noobs like me, who need help to do the installation quicker.

Here I list those which I did as soon as the installation was over.(To access internet)
*If you are behind a proxy,Change the proxy settings. You could find a file "yum.conf" in \etc directory.
Include these two lines in the file

proxy=http://proxyaddress:portnumber
timeout=300
*In \etc\yum.repos.d, you could find 3 files. rpmfusion-nonfree.repo,rpmfusion-free.repo,rpmfusion-nonfree.repo and rpmfusion-freeupdates.repo etc.
In all these files, you could see the following lines

baseurl=http://download1.rpmfusion.org/nonfree/fedora/releases/$releasever/Everything/$basearch/os/
#mirrorlist=http://mirrors.rpmfusion.org/mirrorlist?repo=nonfree-fedora-$releasever&arch=$basearch

Change it to

#baseurl=http://download1.rpmfusion.org/nonfree/fedora/releases/$releasever/Everything/$basearch/os/
mirrorlist=http://mirrors.rpmfusion.org/mirrorlist?repo=nonfree-fedora-$releasever&arch=$basearch


PS:# is to make a line 'comment'

Now we are done. You can access internet from your newly installed fedora. :)

Some additional packages which you would need:
(You must be the root user to install softwares. Type "su" in the terminal)
Adobe flash plug-in: Get the rpm file from http://get.adobe.com/flashplayer
Type
yum install flash-plugin

Unrar:
Get the rpm file from http://dag.wieers.com/rpm/packages/unrar/
Type
yum install unrar

I think these basic packages are enough to start surfing around :)


If you find anything wrong in my post, do post it as a comment.

Gmail Remote Control

0 comments Posted by Suganthi at 4:19 AM



GRC allows you to control your system by sending commands via mail. To do this, you need a simple software calledGRC. To download it, visit www.gianniamato.it. That website is in french I guess. I can give you the direct link to download.Here we go
http://www.gianniamato.it/grc/GRC.zip
All you have to do is hust unzip it. Run the file GRC.exe
Trust me. Its not virus!!
Now, you will be able to see this window.

Sign in here with your gmail id and password.

Once you are logged in with GRC, it checks your inbox every 60 seconds for new command mails.

For example, I wanna open my system's calculator. I mailed my email id from my friend's id(another laptop) with the subject [open]c:\windows\system32\calc.exe[/open]
Yep it worked!!!
Calculator opened on my desktop.

This can be misused easily. Like, if I know that you have your GRC opened, I will mail you with subject shutdown and your system will be off.
It is possible for GRC users to change their commands.

This is what it looks like by default. If you want to change the shutdown command to turnoff, just edit it. You are safe now..!!
You can use your web cam this way to protect your place when you are away.
Now its your turn to experiment with it..

P.S: This works only with windows xp for nw.

Wolfram Alpha

Input your question. They generate your output. Wolfram alpha is a search engine where you get answers for your questions. It is very often referred to as "computational knowledge engine." Fpr eg, I entered the question "How old are you?". It returned its age since it was launched. This search engine is in its developed stage. So you cannot expect answers for all your questions. As of now, you can know about any particular date,town,stocks,mathematical formulae,calculations. The search engine was launched before a month. Let us wait for it to get developed. :)
