As long as it's not gigabit, you can split the network cable, since 100baseTX only needs two twisted pairs of wire. One pair needs to be on pins 1 and 2, the other on pins 3 and 6. The pairs are denoted by a stripe of the same colour (e.g. white/orange and orange/white are twisted together). So, you can take each end of the cable and put two plugs on (or two sockets, whichever you prefer): plug A plug B ----------------------------------------- 1 white/orange white/blue 2 orange/white blue/white 3 white/green white/brown 4 (no wire) (no wire) 5 (no wire) (no wire) 6 green/white brown/white 7 (no wire) (no wire) 8 (no wire) (no wire) You can also buy a ready-made adapter usually called a "cable economiser" which normally plugs into a RJ45 socket. This way, you don't even need the vlans. (Incidentally, someone might be interested to know about SMC GS16-Smart if they're looking for a silent manageable switch; it's meant to support jumbo frames with latest firmware but I haven't made it work yet). > Is some doc of howto install obsd in a usb memory? because i can put in > my room, some 486 or P1, that without hard disk do not produce noise. 486 or P1 are not likely to boot from USB, you need either a compactflash card and a compactflash-IDE adapter, or a disk-on-module (flash memory which plugs straight into the motherboard's IDE socket; ipc2u.com/ipc2u.de have many types). > My old zyxel router, does not have a good answer with DoS attacks, many > connections, etcb& is some way to avoid it or I must change it > unavoidably? You can't really avoid a DoS attack at the end of an ADSL, if someone sends a lot of traffic to you there's not much you can do (except mayb change IP address). Some routers have really small memory and can't NAT a large number of connections; with these it may better to use the router as a bridge, run pppoe on the firewall and NAT there instead (unless your ISP will allow you to have at least a /30 subnet).
