Hey gang, if you follow the latest LFS books and try to run UML, it won't
work. LFS 6x has moved to NPTL, and as we all know, UML and NPTL don't

You can use UML for this, but you will need a pretty massive box in order
to simulate hundreds of machines. With a gig of RAM, I can usually have

Look for the libpcap ringbuffer patch if you are having too many dropped
packets. generic libpcap starts dropping packets at about 50mb per
second, with the ringbuffer patch (should be able to find it on google) it
scales much higher.
