I've done a bit of hunting myself and I've come to the conclusion that this _is_ possible through using DUMMYNET and IPFW (the controller for dummynet). However, having read the DUMMYNET and IPFW man pages and searched Google for tutorials I have turned up very little. What I am trying to do: 192.168.0.1 is a gateway w/ nat. 192.168.0.4 is a downloading machine. 192.168.0.10-20 are workstations. I only have a 56k modem, so if somebody is downloading something from 192.168.0.4 the Internet access effectively stops for the workstations. Therefore I want to deprioritize Internet access from the downloading machine so it only utilizes ``free'' bandwidth. I guess this is almost like setting the nice of a process to 20. Any ideas? One useful page I've found is http://info.iet.unipi.it/~luigi/ip_dummynet/ but I still don't think it has quite what I want to do. -lewiz. -- "Life would be much simpler and things would get done much faster if it weren't for other people" -- Blore ------------------------------------------------------------------------ --|| url: http://lewiz.info/ | http://www.westwood.karoo.net/pgpkey ||--
