# 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
|
|
|
|
* TBD
|
|
|
|
## Copying PPPoE related software components
|
|
|
|
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
|
|
```
