Fixed mac address on the BeagleBoard-xm

[gdamjan]

The BeagleBoard-xm doesn't have a hardware mac address, so it generates one on each reboot.
I'd like to fix it, so that I can assign some parameters to it from my dhcp server.

What would be the best way to do it in ArchLinux, considering I'm running a systemd native Arch, and wicd for automatic handling of network interfaces?

I think it's a smsc95xx, same as rasberrypi pi.
There is a kernel patch (search google for smsc95xx mac address), or maybe you can assign another way before network starts

I tried adding "ethaddr=8e:37:6f:cb:4d:81" to uEnv.txt but that didn't work (that's maybe dependent on that kernel patch).

In the end, I just made a udev rule. Seems to work ok.
/etc/udev/rules.d/99-mac-address.rules
$this->bbcode_second_pass_code('', 'SUBSYSTEM=="net", KERNEL=="eth0", RUN+="/usr/sbin/ip link set dev %k address 8e:37:6f:cb:4d:81"')
I should maybe match more attributes just in case, but it's ok for now.

ps.
to find udev attributes of a net device use this command:
$this->bbcode_second_pass_code('', 'udevadm info -a -p /sys/class/net/eth0')

I fix this issue by creating a file: /etc/rc.d/functions.d/macspoof

The contents of this file are:$this->bbcode_second_pass_code('', '
spoof_mac() {
ip link set dev eth0 address 01:02:03:04:05:06
}

add_hook sysinit_end spoof_mac
')

Make the address whatever you like.

P.S. I also create a file: /etc/rc.d/functions.d/sshd-close-sessions

Which contains:$this->bbcode_second_pass_code('', '
# Close sshd sessions before shutting down the network; see FS#17389.

sshd_close_sessions () {
if ck_daemon sshd; then
return
fi
/etc/rc.d/sshd stop
stat_busy "Stopping Secure Shell Sessions"
for i in $(pgrep sshd); do
if readlink -q /proc/$i/exe | grep -q '^/usr/sbin/sshd'; then
kill $i
fi
done &>/dev/null
stat_done
}

add_hook shutdown_start sshd_close_sessions
')

This will close all ssh login sessions on system reboot.

HTH...
