I also turned off the cable modem for five minuets before rebooting as well, but I suspect it was simply this which did the trick. thanks, -pete. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

DHCP and chnaging the MAC address on a network card
I have a machine runnign 12-STABLE, which gets its upstream IP address from my ISP using DHCP over a cable modem. What I just tried to do was to set the MAC address on that interface at boot time, but if I do that then it no longer acquires a DHCP address from the upstream. Is there something going on here I dont understand ? The interfaces are 'bge' and I have a file called /etc/start_if.bge0 whcih contains: /sbin/ifconfig $1 ether d0:bf:9c:46:a3:7c and this works (have tried it on bge1 and another machine) in changing the MAC address. But if i do that on the DHCP interface then it doesnt get an IP address. Any hints ? -pete. PS: reason am doing this is my ISP will (in future) be able to give me a static IP address basd on the MAC address. Which is lovely, but I have a spare server I use when this one goes down, so was hoping to have the same MAC address if I boot the same drive, to avoid any issues caused by the MAc address chnaging if I chnage the hardware. But it doesnt work. :) ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
