Copying/cloning PPPoE

Copy GlobalOS/Spinix

Issue dmesg command, you can clean current log by using dmesg -c
Insert new flash into USB port
Issue dmesg command again, you should see new device, for example /dev/sdb
MAKE SURE THIS DEVICE IS NEW DEVICE! If you specify wrong one you might lose all data on it
Use gs install to install GlobalOS on the new storage

Configuring networking

You might need to use scp to copy files from one device to another. (WinSCP for Windows, but keep attention on file permissions)

Basic PPPoE components

accel-ppp daemon itself is included in base image, so you don't need to copy it
copy /etc/accel-ppp.conf and adjust according to your needs, we will cover in detail later in another chapter
/etc/add_accel_vlans.sh - script to add VLANs to accel-ppp
Copy certain settings/commands from /etc/rc.local to your new rc.local
/etc/firewall.cfg - firewall configuration, copy it if you need it and dont forget to adjust it
/etc/config.json - shaper config
/usr/local/bin/burst2d - shaper daemon

network.cfg adjustments

sysctl -w net.ipv4.conf.eth4/999.proxy_arp=1 Enable proxy-arp if you have real IP addresses on PPPoE shared between multiple pppoe, enable it on "WAN" interface of PPPoE

shaper daemon startup

Create directory for example /etc/service-burst2d
Create file /etc/service-burst2d/run with following content:

#!/bin/sh
/usr/local/bin/burst2d

Make it executable
add to /etc/rc.local

runsv /etc/service-burst2d &

accel-ppp.conf

Allocate new subnet and route on your core router

[ip-pool]
gw-ip-address=10.255.255.1
attr=Framed-Pool
X.X.X.X/MASK

Update dae-server (CoA) entry with new PPPoE IP

dae-server=Z.Z.Z.Z:1700,NASSECRETSOMETHING

Make sure radius entry is correct

server=X.X.X.X....

add_accel_vlans.sh

In old versions of script you might have fixed interface name, make sure it match interface where pppoe vlans are connected. For example eth4:

  ip link add link eth4 name eth4.$VLANID type vlan id $VLANID

Change if necessary over all script

/etc/hosts

Make sure hosts have correct entry for localhost

pppoe /etc # cat /etc/hosts
127.0.0.1 localhost

Preferable tuning for PPPoE

Disable TSO, GRO, GSO for better shaper precision on ethernet and bonding interfaces

ethtool -K eth4 tso off gro off gso off
...

Make sure gc_thresh* tuned for PPPoE

echo 2560 > /proc/sys/net/ipv4/neigh/default/gc_thresh1 
echo 5120 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 10240 > /proc/sys/net/ipv4/neigh/default/gc_thresh3

conntrack max entries

sysctl -w net.nf_conntrack_max=2000000
