ethtool

You can change the aggregate speed of the NIC port using ethtool.

$ sudo ethtool -s eth0 speed 10

This will set the port to 10MB, for example.

wondershaper

You can also use the tool wondershaper to do it as well. NOTE: Speed should be in kilobits per second.

$ sudo wondershaper eth1 downspeed upspeed

For example:

$ sudo wondershaper eth0 10000 280

trickle

A 3rd option is trickle. Trickle can be used per program by users or as a daemon that throttles the NIC completely.

User mode - trickle man page

$ sudo trickle -d 20 -u 20 wget http://www.google.com/bigfile

Will throttle 20K/s for both up and down traffic for just this wget, everything else will not be limited.

Daemon mode - trickled man page

In daemon mode, trickled can limit a group of programs to a fixed limit of bandwidth. To start the daemon, run the trickled command:

$ sudo trickled -d 20 -u 20

pyshaper

A 4th option is pyshaper. It’s a unique option among the choices in that it includes GUI and it dynamically monitors and sets the bandwidth over time. You can check out the pyshaper man pagefor more details.
