View Full Version : MAC Address Conflict

I now have two Tivo's on my LAN and they both have the same MAC address.

Is there anyway to change this without putting the drive back into my PC?? :D

If you used these directions from the how to...

Add to bottom of rc.sysinit with joe.
Place the added lines after the line:
echo "rc.sysinit is complete"

bash-2.02# joe /etc/rc.d/rc.sysinit

# add Turbonet card support to DirectTivo With serial bash already running.
# replace the IP adresses as needed...
# example Tivo IP address =
# example Network Mask =
# example Default Gateway =

tnlited 23 /bin/bash -login &
insmod -f /lib/modules/ax88796.o macaddr=010203 timing=5
ifconfig eth0 netmask up
route.tivo add default gw

you can edit the macaddr=010203 to something else. Remember a mac address can consist of 0-9 and a-f.

if you leave the macaddr variable off, then the TurboNet will pickup the last 6 characters of the the serial number of the TiVo as the last 6 of the MAC Address.

i think it only does that (the serial number thing) if you're using the 3.x tivo-supplied "unsupport" for daily calls. on my turbonet installs, it's always defaulted to the same address and i have to make sure i change it.

Kraven's update and the SZ variants that use the same DHCP config assign the serial number environment variable to the MAC setting. I don't think Nick's driver does it on its own, BIMBW.

correct. the nic_install procedure from jafa's site doesn't do the serial number for mac thing. i haven't done akraven or sz install, so i can't speak for those. i do agree it's a good idea, because it's easy to overlook.
