I am looking for software to do IP and Ethernet testing. I need a tool that acts as an ethernet bridge on my network to test network applications. I am looking for something that will emulate network error conditions like packet loss, delay and bandwidth restraints. If anyone out there knows of such an application please let me know. Since my project has limited funds I am looking for something like shareware, freeware or a GNU General Public License (GPL).
Thanks in advance.
