Hifumi: Printer server

Hardware - R2S

Network

• eth0 - RTL8211E
• eth1 - RTL8153

The RTL8153 device needs MAC assignment as it will use random value by default:

SUBSYSTEM=="net", ACTION=="add", KERNEL=="eth1", PROGRAM="/sbin/ip link set %k address 8a:f4:c8:41:48:35"

Leds

Make red sys led bright when we have booted to runit:

echo "1" > /sys/class/leds/nanopi-r2s:red:sys/brightness

Make red sys to blink on SD card activity and wan/lan on data transfers between eth0 and eth1 (GUEST/internet network access):

modprobe ledtrig-netdev
echo "netdev" > /sys/class/leds/nanopi-r2s:green:lan/trigger
echo "eth0" > /sys/class/leds/nanopi-r2s:green:lan/device_name
echo "1" > /sys/class/leds/nanopi-r2s:green:lan/link
echo "1" > /sys/class/leds/nanopi-r2s:green:lan/tx
echo "0" > /sys/class/leds/nanopi-r2s:green:lan/rx
echo "netdev" > /sys/class/leds/nanopi-r2s:green:wan/trigger
echo "eth1" > /sys/class/leds/nanopi-r2s:green:wan/device_name
echo "1" > /sys/class/leds/nanopi-r2s:green:wan/link
echo "1" > /sys/class/leds/nanopi-r2s:green:wan/tx
echo "0" > /sys/class/leds/nanopi-r2s:green:wan/rx
echo "mmc0" > /sys/class/leds/nanopi-r2s:red:sys/trigger

Printer setup

Configure and unpause all printers

#!/bin/sh -x
lpstat -le | grep ' permanent ' | cut -f1 -d' ' | while read P; do
	lpadmin -p "$P" -o printer-error-policy=retry-current-job
	lpadmin -p "$P" -o printer-is-shared=true
	lpadmin -p "$P" -E
done

Printer status

lpstat -t

Guest VLAN bridge

This will bride eth0 to GUEST VLAN (10) on eth1.

in /etc/rc.local:

ip link set eth0 addrgenmode none up
ip link add link eth1 name guest type vlan id 10
ip link add br-guest type bridge
ip link set guest master br-guest
ip link set eth0 master br-guest addrgenmode none
ip link set br-guest addrgenmode none up

Prevent DHCP from running on eth0.

In /etc/sv/dhcpcd/conf:

OPTS="-M --denyinterfaces eth0"
