Network Traffic measuring tools

[Jatin Davey]

Hi

I a new user who has just switched from windows vista to Ubuntu 9.10. I 
have a DSL connection in my home and i use my toshiba laptop connecting 
to the DSL router and use the internet. I need a tool that will monitor 
the traffic that goes through my wireless or ethernet adapter. I used a 
tool on windows Vista called as "Netmeter". This gave me monthly , daily 
and weekly reports.

Thanks
