yeah, i agree on that but that is already doing malicious attack on the network. you can use other programs to do that intentionally. macof is part of dsniff package which intercepts network traffic. as far as i know there are countermeasures on switches for such attacks. anyway, larry's problem is upon installation of mdk 8.2, he claimed his network went down because of it, and that is what im surprised about. unless you tell me that mandrake expert install has macof enabled to bomb the switch ;-) > ECS is certainly not gilt-edged hardware, and one > can expect more than > an average share of problems on something made by > _any_ member of the > PCChips group, but I have noticed much better > performance on 8.2 with > most ECS junk than on 8.1 or the betas. > > No big changes were allowed from RC1 to final.
