Interesting. Does it also help you somehow to produce lag?
No, I'm afraid not. The only way I can think of doing that would be to use -j QUEUE and write a queue handler to introduce the lag. However I have no idea how tricky this would be...

I don't think so. But I realized that there is nistnet functionality built in most distros with new kernels through a module called netem. You can use that together with tc to get the same functionality you get from nistnet, without all this hassle. Someone should have told me earlier. Just download knoppix, execute tc with some paremeters and that's it. And, last but not least, netem can also be used for creating lag while bridging, not only routing.

I also searched about usage of netem on OpenWRT. That'ld be really cool. Those Linksys devices are quite cheap and that'ld give you/me some switch-equivalent or router-equivalent (whatever you prefer) with lag switchable on or of. I found an irc log with a discussion about that. It seems like it is belived that it works if you use the experimental version of OpenWRT (the older ones use older kernels where netem isn't available) and compile the kernel with the netem module yourself. It is not in the precompiled version to save space.

Well, crosscompiling embedded linuxes is beyond what I can do/want spent time on. But if there is someone willing to do it, I would be interested in the ready to use firmware

Finally a reason to go to a 3rd party firmware...

I'm running a WRT54G on my home network. I've been meaning to "upgrade" to a 3rd party firmware, but I could never fine the killer app reason to do it. Now I've got that reason. All I need now is time. Anyone know where I can buy some?

No sorry. I'm still dreaming of an 8th day every week that only I have.

If you get it working on a linksys, please report.
