Wanna Mail?... but later ?.. must use websites!!!!!! for e-mailing

2008-03-12T15:34:00.001+05:30

MailFreezr.com

Now, we usually think of e-mail as a way to instantly communicate, but what happens if you want to freeze e-mail to send at some point way down the line?

MailFreezr is a website which stores your mail for - wait for it - up to a century - and then finally pings it into cyberspace. All you do is fill out a few details on a basic form and voila, a missive ready to send in the future, so you never have to miss that cousin's anniversary ever again.

MailFreezr's creator says messages are secure and confidential and will be sent on time, though filling in e-mail addresses on the web does make you prey to spam harvesters.

Aside from the obvious problem that e-mail may well not be around in 50 or 100 years, the biggest drawback of Mailfreezr is that you can only freeze an e-mail in yearly increments.

FutureMe.org

The BBC is not responsible for the content of external internet sites.

If you want to use a slightly more sophisticated service, then head down to FutureMe.org.

Here you can choose precisely which date you want your e-mail to be sent on. To prevent misuse of the service you have to sign-up and confirm the e-mail address you want to use as the sending address.

Then after logging in, you are away: just fill in the fields and you are off. It is that simple.

You can make your e-mails semi-public too which other users can read randomly on the site itself.

FutureMe is primarily designed so you can make a statement or prediction about yourself, not tomorrow or next week but some point a little further down the timeline of existence.

And to stay true to that philosophy, the site actually prevents you sending an e-mail less than 3 months into the future; as the founders makes clear, this site is not a reminder service.

Now, if you are after a reminder service, then you will need what is called an e-mail scheduler.

There are several out there, mainly in the form of plug-ins to your existing e-mail applications or office suite. But LBE Email Scheduler is one which is a standalone application, though like the others you have to pay for it after a trial period.

Getting Connected to the broadband Internet On Linux !!!!

2007-10-21T12:37:00.001+05:30

BSNL DataOne

Prerequisite

BSNL Dataone provides different types of ADSL modem/router:

Huawei ADSL modem/router with ethernet and USB port
DareGlobal ADSL modem/router with ethernet port.
Huawei ADSL modem/router with ethernet port, USB port and built-in wireless access point.

You should have a working ethernet card to connect the modem/router. No information is available about connecting using USB (PPPoA).

Instructions

Note: The router/modem would trigger the connection if configured this way.(Router on -> Connected)

Ethernet Connection

Connect the modem/router to the ethernet card
Assign an IP address for the ethernet card; the router has a fixed interface address of 192.168.1.1, so you can use 192.168.1.2 for your ethernet interface.
```
$ sudo ifconfig eth0 192.168.1.2
```
Add 192.168.1.1 as default gateway.
```
$ sudo route add default gw 192.168.1.1
```
Enter the address of some DNS servers in /etc/resolv.conf. These DNS adresses are provided on BSNL's instruction manual.
```
$ sudo vi /etc/resolv.conf
```
The entry will be of type nameserver 61.1.96.71, where the IP will be the one provided in your DataOne instruction manual.
Access the router's management interface via a browser by typing the address 192.168.1.1. The admin username/password is admin/admin

Set the connection type to `PPPoE'. On my MT882 box, this comes under `WAN Settings'
Enter your user name and password (username is of the form xyz@dataone)
Reset the router. It will take 2-3 minutes for the box to come up again

Steps 2, 3, 4 can also be done from menu System->Administration->Network in GUI

Alternate Method:

Connect your ethernet wire to the port at the back of your computer.
Fire up the terminal and type in sudo pppoeconf
It should detect your modem.
Keep on pressing enter. Fill in your user name and password when indicated.
It should be easy to stick on to defaults.
You should be prompted back to your terminal when it would say pppoe loaded. Simple. That's the end of terminal.

Now go to System>Administration>Networking. Click on it. You would be asked for your password to carry out the administrative job as root. You should be prompted to enter the following details.

Activate the Wired connection.
Highlight the wired connection and click on properties.
Check the box "enable the connection"
Configuration as Static IP.
IP AddressÂ : 192.168.1.2
Subnet mask fills on it's own as 255.255.255.0
Gateway addressÂ :192.168.1.1

Wireless Connection

Assign an IP address for wireless NIC; the router has a fixed interface address of 192.168.1.1, so you can use 192.168.1.2 for your wireless NIC.
```
$ sudo ifconfig wlan0 192.168.1.2
```
In some cases you may need to replace wlan0 with with eth0 or eth1.
Add 192.168.1.1 as default gateway.
```
$ sudo route add default gw 192.168.1.1
```
Add network ESSID.
```
$ sudo iwconfig wlan0 essid WA1003A
```
Default ESSID for the modem/router provided by BSNL are same as model names. You can change it from modem/router's admin console.
Enter the address of some DNS servers in /etc/resolv.conf. These DNS adresses are provided on BSNL's instruction manual.
```
$ sudo vi /etc/resolv.conf
```
The entry will be of type nameserver 61.1.96.71, where the IP will be the one provided in your DataOne instruction manual.
Access the router's management interface via a browser by typing the address 192.168.1.1. The admin username/password is admin/admin

Set the connection type to for PVC0 connection as 'PPPoE'. On WA1003A modem/router, this comes under 'Setup'
Enter your user name and password (username is of the form xyz@dataone)
Set the modulation to GDMT. On WA1003A modem/router, this comes under 'Setup->Modem Setup'
Save and restart the modem/router. On WA1003A modem/router, this can be done under 'Tools->System Commands' It will take 2-3 minutes for the box to come up again

Wireless security

In admin console, 'Advanced->Wireless Security' set security to WEP.
Add a 64 bit authentication key, 10 characters in hex format i.e 0-9 and A-F
Add this key to wireless NIC configuration.
```
$ sudo iwconfig wlan0 key A1B2C3D4E5
```
Save settings in router and restart it. Reactivate the card, probably using ifdown and ifup

One stop instruction for wireless NIC:

Add following lines to /etc/network/interfaces

iface eth0 inet static address 192.168.1.10 netmask 255.255.255.0 gateway 192.168.1.1 wireless-essid WA1003A wireless-key A1B2C3D4E5  auto eth0

Most of the steps can also be done from menu System->Administration->Network in GUI

(Note: Most of the instructions are based on the document at http://www.calcuttatelephones.com/dataoneinstall/bb008.html)

Alternative

Note: Ubuntu would trigger the connection if configured this way.(Router on -> Ubuntu on -> Connected)

Make sure your Ethernet card is configured
Open a Terminal: Applications->Accessories->Terminal
Enter sudo pppoeconf
Follow instructions on the screen. The defaults are fine for most cases. Make sure you enter your username and password carefully. BewareÂ : The password will be visible on the screen.

Checking Usage

Casanova has made a python script for checking dataone usage.

Dataone usage script

MTNL Triband

MTNL Triband offers DSL 502T Dlink Router for ADSL for those who opt not to buy one. However, I would recommend buying the same router, if one chooses not to pay rent to MTNL for this modem. This router has known to work without issues for me.

Users who try out Ubuntu Live CDs would have to set up DNS as shown below. For Kubuntu Users, Konqueror automatically detects the network (if through ethernet) and one can access without any configuration.

Ethernet

For users, who have connected their router to the Ethernet card, only have to setup the DNS address as provided by MTNL.
Follow the following steps
1. Go to System->Administration->Network
2. Move to the DNS Tab
3. Click on the default entry (which could be 192.168.1.1) and click on "Delete" button
4. Click on "Add" button and enter the DNS address. You would have to call up on 1504 and get DNS addresses.

USB

At the time of writing this, Ubuntu 6.10 is able to detect the device (DSL-502T) Router provided by MTNL. However, it is not able to understand network through an ADSL connection and send / receive packets. However, I tried connecting using USB, and was able to access the internet using Kubuntu 6.06 (Dapper Drake) which recognized the device as well as the network. The device was able to allocate an IP address using DHCP and requires no further configuration.

Checking usage

For finding out your usage, you can log on to http://register.mtnl.net.in and input your telephone number as "username" and the password as your "CA" number, if you haven't changed it. Click on Account Summary on the left pane, when you are in.

Sify

Obtaining the sify dialer

Download the client from the same place where you got the windows client. This should ideally be http://202.144.65.70:8090 , and at the time of writing the file is can be found at http://210.18.11.199:81/bbandclient/sifyconnect-1.3-bin.tar.gz. or http://210.210.4.74:81/bbandclient/sifyconnect-1.3-bin.tar.gz

Installing the dialer

Untar the the dialer using your favorite untar program , or do thisÂ :

$ tar -xzvf sifyconnect-1.3-bin.tar.gz

Then run the following commands as rootÂ :

$ cd sifyconnect-1.3-bin/ $ bash install.sh

 Using the dialer

Run the following commandsÂ :

$ sifyd $ sifyconnect -l

This will prompt you for your username & password , give them. Once you do that your as good as logged in , you can now close the terminal and use the internet.

Autologin

Want to automatically login onto sify everytime you switch on the computer. Just write a shell script. Just make a file (something like sify.sh) in "/usr/bin/". The scriptwill be something like thisÂ :

$ sifyd $ echo -e 'accountname\npassword' | sifyconnect -l

To start this everytime the computer switches on add the following lines to the /etc/rc.local file (untested):

$ bash sify.sh

 Troubleshooting

Sometimes the client on trying to log in says something like --

"Login failedÂ : Get the latest version of the client"

This is because after upgrading it's protocol in some places, sify has discontinoued support for the old protocol . It has also stopped development of it's GNU/linux and Mac clients , so you might have to call sify customer care and tell them your problem. They probably just allow you IP and account to use the old protocol It took them about 8 hours to fix the problem when I had it.Â :D

Another problem that might occur would be like --

"-bash: /etc/init.d/sifybb: No such file or directory"

If that ever happens all you have to do is Broadband_Howto#Installing_the_dialer again.

PPPoE (non bridged)

In this mode, your router will connect as sson as it is switched on. If you are billed for time connected then you need to use bridged mode

Go to System->Administartion->Networking and make sure you have configured an ip (192.168.1.2, for example) and have set your DNS (supplied by Airtel) and Default gateway (192.168.1.1). If your router is handling DHCP then you needn't configure an ip.
Navigate to http://192.168.1.1
Enter the username and password (default is admin for both)
Click Run Wizard
Click Next
Select your time zone (+5:30)
Click Next
Select <PPPoE/PPPoA Choose this option if your ISP uses PPPoE/PPPoA. (For most DSL users)>
Click Next
Enter your username and password. VPI = 1, VCI = 32, Connection Type = PPPoE LLC

Seven Post-Install Tips for Ubuntu 7.04

2007-09-03T22:06:00.000+05:30

Fixes, extras, and eye candy: Here are seven steps to take just after installing Feisty Fawn.

So, you've just installed Ubuntu 7.04, otherwise known as the "Feisty Fawn" release of everyone's favorite (for now) flavor of Linux. You booted the installation disc, looked around the test environment to discover that your hardware was working, and double-clicked the Install icon on the desktop. The Ubuntu installer helped you make room for Linux on your hard drive, and even copied over some of your documents and settings from Windows.

Half an hour ago, you had only Windows on your PC, but now you have a choice at boot time, and a whole new world to explore. Congratulations!

But wait--before you dive in too deeply, here are seven steps you can take right away to prevent common headaches and help yourself enjoy your new surroundings.

1. Fix your right Alt key.

U.S. users may notice before too long that the right-hand Alt key on their keyboard doesn't work in Ubuntu. This will drive you nuts if you frequently use that key. (I use mine constantly for the Alt-F2 Run command in Gnome.)

By default Ubuntu assigns the right Alt key (but not the left one) to "third level" character input--that is, the key is reserved for entering extended and international symbols. This is good for our Ubuntu-using friends in places where third-level characters are in use, but the Gnome Keyboard Indicator applet shows that the U.S. English keyboard layout contains no third-level symbols. So for us statesiders, our right Alt key has been mapped to a function that we cannot use in the first place.

To get the right Alt key to behave like the left Alt key, select System, Preferences, Keyboard. On the Layout Options tab, open the 'Third level choosers' branch, and reassign the third-level chooser to another key. (I prefer the right Windows key--my laptop doesn't even have one of these, so I am actually assigning a useless function to a nonexistent key!)

2. Fix your screen resolution.

You've booted into Ubuntu and your expensive high-res display is running at a paltry 1024 by 768 resolution instead of the 1280 by 1024 or 1600 by 1200 you're accustomed to. So you click System, Preferences, Screen Resolution, only to find that the higher resolutions you know your display can support are not offered in the drop-down list. What the heck?

This is usually an indication that Ubuntu has failed to suss out the characteristics of your monitor. (Graphics card woes are also possible in this case, but in my experience monitor trouble is more common.) Luckily, a helpful Fix Video Resolution Howto in the Ubuntu wiki has solved this issue every time I've encountered it. The instructions there should be enough to get your display in gear.

3. Install Automatix.

Automatix is a gem that I've discussed before: It's the easiest way to add certain components to your system that are not included in a default Ubuntu installation for legal reasons. Automatix makes enabling DVD support, for example, a very simple point-and-click process.

Head to the Automatix installation page and follow the download and installation instructions for Feisty.

Once that's done, you'll find Automatix under Applications, System Tools, Automatix. See my previous coverage of Automatix for pointers that are still relevant with this latest version.

4. Make sure all your media files play.

Start double-clicking your various audio and video files to see if they play. (You'll find links to your Home folder and your Windows partition--if you have one--in the Places menu, so start there to find your media collection.) When Feisty encounters a file type it doesn't know how to handle, an automated codec installer will pop up to try to help you download and install support for the file in question.

If you find video files in your collection that do not play properly no matter what you try, use Automatix (see above) to install the AUD-DVD Codecs collection of packages; then use Synaptic (see below) to install the Totem-xine package, and try your videos again. (This procedure disables Feisty's ability to automatically search for codecs, but you're taking this step only if that functionality fails you in the first place.)

5. Give Desktop Effects a shot.

In my last column, I looked at Feisty's Desktop Effects--an experimental feature set that brings gee-whiz 3D effects to the Linux desktop. If you have a decent graphics card with 3D capabilities, it's totally worth your while to see if Desktop Effects will run well on your system. (The features work reliably on some machines, crash after a while on others, and completely garble the display on particularly unlucky PCs--hence the designation "experimental.")

To try out Desktop Effects, select System, Preferences, Desktop Effects. When the 'Enable the driver?' dialog box pops up, click Enable Driver. You'll now be prompted to restart your computer (a rare thing in Linux land).

Once you do, log back in and select System, Preferences, Desktop Effects again. In the new dialog box, click the Enable Desktop Effects button. After a few moments of on-screen craziness, your desktop should reappear, looking as it did before. But you'll notice a difference the moment you drag a window or open a drop-down menu. (Yowza, look at that!)

If everything looks good, click Keep Settings in the dialog box asking you to confirm the change. (If things look bad, this is your first chance to bail out. If things are so poor you can't even see the dialog box, have no fear: Feisty will automatically revert to your former settings after 30 seconds.)

Try enabling the workspace-switching effect back in the Desktop Effects box; when you click to a different workspace (via the widget in the lower right of your screen), you should see a nifty effect. Also note the altered behavior when you press Alt-Tab.

If you don't like what you see with Desktop Effects (or if you find that your system becomes crash-prone or otherwise behaves oddly with the Effects, uh, in effect), you can turn them off by once again summoning the Desktop Effects dialog box and clicking Enable Desktop Effects. Yes, you read that right: The button behaves as a toggle--though, alas, at this point in time its label doesn't change to 'Disable Desktop Effects' to indicate this to the user. But clicking the button when effects are enabled disables them, as you will see if you click the button and then move a window around.

6. Try Beryl for unbeatable eye candy.

Feisty's Desktop Effects are driven by software called Compiz, originally developed at Novell. Last year some enterprising hackers working on Compiz decided to fork (that is, split off from, using existing code as a starting point) the project, and came up with their own offering, Beryl. The two projects are actually slated to merge their efforts back into one program later this year, but in the meantime, if Desktop Effects work reliably on your machine, chances are the latest version of Beryl will work too. And Beryl is far more impressive--and far more configurable--than Desktop Effects.

To test-drive Beryl, first disable Desktop Effects by using the oddball toggle button I described at the end of tip #5. Now open a Terminal window (Applications, Accessories, Terminal) and enter the following command:

sudo gedit /etc/apt/sources.list

Add the following line to the top of the text file that comes up for editing:

deb http://ubuntu.beryl-project.org feisty main

Save the file and quit. Now back on the command line, issue the following four commands, one at a time:

wget http://ubuntu.beryl-project.org/root@lupine.me.uk.gpg -O- | sudo apt-key add -

sudo apt-get update

sudo apt-get install beryl beryl-manager emerald-themes heliodor beryl-manager

beryl-manager

There should now be a shiny red gem appearing in the notification area (Windows refugees, think "system tray") near the upper right of your screen. Right-clicking that icon gives you several useful options.

Select Window Manager lets you switch among Beryl, Compiz, or Metacity (the default, plain-vanilla window manager for Gnome). Select Window Decorator affects how the frames of windows are drawn. Select Emerald, and you'll get window frames designed with Beryl in mind. (See Emerald Theme Manager, also in the red gem's menu, for more of these.) Select Heliodor, and you'll get plain window borders imported from Metacity.

Selecting Beryl Settings Manager will bring up the labyrinthine configuration dialog box for Beryl. Warning: If you're a settings geek, you will lose a few hours of your life here. Take note of where you can assign functions to the corners of the screen: Select General Options along the top and Shortcuts along the right, and then click the Screen Edges tab. The horribly named 'Initiate Window Picker for All Workspaces' function is the equivalent of Mac OS X's ExposÃ© feature--task-switching nirvana, if you ask me.

If Beryl runs stably and you'd like it enabled every time you log in, select System, Preferences, Sessions. On the Startup Programs tab, click New. Enter beryl-manager in both text-entry fields and click OK. Now click Close.

7. Make friends with the package managers.

An entire planet's worth of Free Software is out there for Ubuntu systems, and you don't have to trek across the Web and back to find it all. In the last tip, we interacted with a command-line package manager (the part of a Linux system that tracks what is and what is not installed) just for expediency's sake. But now it's time to meet two friendlier interfaces for package management.

First off, there's the Add/Remove Applications dialog box, reached via Applications, Add/Remove. Unlike its Windows counterpart, this tool is very good at downloading and installing new applications. You'll be surprised by the number of offerings, and in some cases you'll even be downright shocked by the high quality of the software you retrieve.

If you want to see a geekier, more fleshed-out listing of all available packages, select System, Administration, Synaptic Package Manager. Whereas Add/Remove Applications is a friendly little forklift of a package manager, Synaptic is a heavy-duty earthmover. If you're interested in learning more about the packages that make up your system (and the ones waiting to be discovered), Synaptic's various views are good places to explore.

I could spend a whole 'nother column telling you about all the great packages that are not installed by default, but for now I'll just leave you with this bonus tip: If you're running Ubuntu on a laptop and your Wi-Fi card is not detected or supported, try installing the Ndisgtk package (listed as such in Synaptic, but as 'Wireless Windows Drivers' in Add/Remove Applications). Then select the new System, Administration, Windows Wireless Drivers entry in Ubuntu's menu bar. The ensuing dialog box asks for the location of an INF file that represents the Windows driver for your wireless adapter. Have a driver disc? Find the INF file on there and see if Ndisgtk can get you up and running.
