If I boot from CD-ROM (using a freebsd9 FreeBSD 9 CD), I can go to shell. I can configure the network interface, I can set the IP address, netmask, gateway, I can ping the local machine, internet machine (by IP address), but I don't understand how to set the DNS nameserver. I can't modify /etc/resolv.conff because it's read-only. Is there a way to set DNS without having to mount a local partition? Thanks.
