The bananapi does currently assign random mac addresses to its ethnernet nic,
|
||
|
|
which is bad if you want to assign static dhcp leases. To solve this issue just
|
||
|
|
create the following udev rule:
|
||
|
|
|
||
|
|
``` plain /etc/udev/rules.d/75-static-mac
|
||
|
|
ACTION=="add", SUBSYSTEM=="net", ATTR{dev_id}=="0x0", RUN+="/usr/bin/ip link set dev %k address XX:XX:XX:XX:XX:XX"
|
||
|
|
```
|
||
|
|
|
||
|
|
Replace XX:XX:XX:XX:XX:XX with your current mac address:
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
$ ip address
|
||
|
|
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN group
|
||
|
|
default
|
||
|
|
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
|
||
|
|
inet 127.0.0.1/8 scope host lo
|
||
|
|
inet6 ::1/128 scope host
|
||
|
|
valid_lft forever preferred_lft forever
|
||
|
|
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
|
||
|
|
group default qlen 1000
|
||
|
|
link/ether 02:8a:03:43:02:2a brd ff:ff:ff:ff:ff:ff
|
||
|
|
inet 192.168.1.56/24 brd 192.168.1.255 scope global eth0
|
||
|
|
inet6 fe80::8a:3ff:fe43:22a/64 scope link
|
||
|
|
valid_lft forever preferred_lft forever
|
||
|
|
inet6 fe80::9985:bd71:3b59:4875/64 scope link
|
||
|
|
valid_lft forever preferred_lft forever
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
which is `02:8a:03:43:02:2a` in my case.
