Hi, I need to simulate (with a certain degree of control) common WAN problems like packet loss/duplication, delay and conditions of limited bandwidth. I found that NISTNet is what i need, but it seems the package has not been updated since October, 2000. This is not really a problem as I found NISTNet runs perfectly with Linux kernels up to 2.4.23 (officially 2.4.18 is the latest mentioned in documentation). What then am I complaining about ? Well, it seems that NISTNet is intercepting IP packets before the conntrack can do its job in the PREROUTING phase. So if you are doing SNAT or DNAT on the same machine where NISTNet is running, you can not use the de-NATed IP addresses to build rules. I certainly can find solution to this problem by altering my test topology and tweaking a little bit network configuration, but still the question remains: Is there any fresh substitute for what NISTNet does ? _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
