Backspace, Tab not working in terminal (using ssh) [closed]

view story

http://serverfault.com – When I ssh into another machine with Debian with my account(with sudo permissions), my backspace key generates some awkward symbols on pressing. Also Tab & del keys don't work too. On the other hand, I also have another account on the same machine & when I ssh through this account, its terminal works perfectly fine. I couldn't figure out why is this happening. (HowTos)
