I run Ubuntu. I need to add some latency and/or some network errors to see if my application can handle with network failure ( connecting & disconnecting ). I found "tc" tool which will be helpful to add latency and make the interface more faulty. My concern is that tc will affect my eth0, which is not good, cause I need to have connection with network and Kerberos. Is it possible to "copy" a link and simulate network problems only on "copy" of network interface?

If yes, what is the tool/technique?

Probably the easiest implementation for what your thinking about here is a VPN connection. It creates a virtual adapter that can work alongside the physical one. Linux supports Open VPN which seems pretty well suited to the problem your describing. You might consider moving your development environment onto a virtual machine, which would allow you to more easily test things like latency and bandwidth without interfering with the mundane function of yout desktop machine.
