Re: aliasing a point-to-point interface
G'day folks, I used to do this on my permanent link at home a while ago -- my ISP provided me with a /30 network address with which to run the point- to-point link, and then they routed my class C via my end of the /30, and I was told to default via their end of the /30. This meant that when originating connections from my FreeBSD system, it would be sourced on the /30 address at my end - and therefore subject to my ISPs reverse mappings, not my own class C's. So to force my connections to originate from one of my IPs, I would delete the PPP address that was negotiated with PPP (after pppd was completely connected), and added one of my own with ifconfig, ala: ifconfig ppp0 delete ifconfig ppp0 10.1.1.1 netmask 255.255.255.255 192.168.1.1 alias route delete default route add default 192.168.1.1 now while 192.168.1.1 doesn't exist, and I can't ping it, sending my default traffic via that address forces it to be sent out via the ppp link, and the router at the other end doesn't give a hoot about the fact that I sent the packet to the wrong address, all it cares about is where to send the packet next :) And yes, I can ping 10.1.1.1 from outside my network, so all works as expected.

Re: Where are the Disk on Chip drivers?
Hi Jaye, All of the DOC stuff I've played with has usually had an IDE style interface associated with it - I may be way off track here tho...?

Any help appreciated. I want to run under 3.2-stable.
