This is a simple bash script to help you simulate real network conditions with tc (iproute2). Profiles are based on those from Apple's Network Link Conditioner tool.
It's been tested on Ubuntu 12.x.
netcond start [interface] [profile]
netcond stop [interface]
netcond stats
Where [interface] := the network interface to use e.g. lo, eth0 or wlan0
[profile] := the profile to use (must exist in the profiles directory)
Note You will probably need to run this with sudo
# simulate a wifi network that is unstable on eth0
sudo ./netcond start eth0 wifi-lossy
# view some tc statistics
sudo ./netcond stats
# stop the simulation and clean up
sudo ./netcond stop eth0
- make ingress and egress traffic shaping separately configurable to simulate asymetric upload and download
