Joggers getting same IP address

Post by joggy »

Hi,

I am trying to run 2 jogglers with the birdslikewires Ubuntu Bionic (Kernel 3.16) for OpenFrame image but they keep getting the same IP4 address via DHCP. I checked and they have a different MAC address and I even changed the hostname in /etc/hostname but they still get the same IP. Anyone knows how this should be fixed? thx!

Code: Select all

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.64  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fd95:c79b:3c7d::99f  prefixlen 128  scopeid 0x0<global>
        inet6 fe80::a0:86ff:fe2d:b48e  prefixlen 64  scopeid 0x20<link>

You can put a mac address / firmware on the Realtek NIC on the Joggler if you want.

1 - you basically write an image to any USB stick to do this.
2 - replace the EFI bios with a Seabios
3 - write the mac address to the Realtek chip via command line once you boot in to DOS
4 - reboot and hit the F12 key and reload the Joggler EFI bios
5 - you should be good to go then.

I changed the MAC via bios as you described, I changed the MAC in /boot/network.yaml and I changed the hostname via hostnamectl but they still get the same IP address??!??

Guessing you made each MAC address unique to each Joggler?



Install ethtool

sudo apt install ethtool

sudo ip link show

Each joggler should have a unique MAC address.

Then do:

sudo ethtool mac_address

This will show the hardware nic specs.

Both Jogglers hardware mac addresses should be unique.

Try this also:

lshw -class network

This will show the MAC address after serial:

The two jogglers should have unique mac addresses.

do a copy and print of what you see and post it here please.

Apologies I did not read your previous post.

I am assuming that you assigned a unique mac address to each Joggler eh?
