Unable to enter password in terminal to enter as root..
 

Hello friends.. I'm a newbie in linux..
I have searched a lot on many forums and succeeded in connecting to internet using my wll phone. I can now connect using 'wvdial' command in root terminal. But I want to connect through terminal. I tried 'sudo wvdial' command. Then I am asked for my password. But I cannot type my password there. When I type, nothing appears on the terminal window. Ofcourse there's no problem with my keyboard. Please help me.

That's normal. Nothing is echoed at password prompts. Just type your password and hit enter.

perfectly normal, as alucard says.

When you're hitting your password, you're not supposed to see it on screen, nor the "usual" asterisk mask.

It's just a safety measure, if someone's watching over your shoulder or something

Sir..
Thank you for your reply. It works when i swith user using 'su'command. But not with 'sudo'. Pardon me if its a too silly problem..

I believe that when you do sudo (assuming you have permissions to execute sudo) the password it asks for is your password, not root. su requires the root password.

'sudo' is not enabled by default on Debian.
