How to intentionally degrade an outbound connection in linux

Question

I am testing the timeout handling for an outbound CURL in a PHP app I am developing after an outage at an affiliate brought down my site. I am looking for a way to intentionally slowdown or permanently stall outbound connections to a specific IP address so I can tune my timeout schema. Is there any way to do this?

The Charles proxy server can do connection throttling, e.g. artificially increasing the latency or limiting the bandwidth. Install it and use the cURL CURLOPT_PROXY option to point PHP to the proxy server.

The linux traffic shaper, although normally used to enforce QoS, is also perfect to degrade connections arbitrarily.

To completely block traffic you could do an iptables drop command for the outbound traffic to that dst address.

ie

iptables -A OUTPUT --dst 129.232.64.145 -j DROP
