Configuring additional NIC's
- Cluster networks between Headnode and Nodes.
- Group 1: 10.100.1.0/24
- Group 2: 10.100.2.0/24
- Group 3: 10.100.3.0/24
- Headnode public IP address
- Group 1: 192.168.139.21
- Group 2: 192.168.139.22
- Group 3: 192.168.139.23
- Switch: 192.168.139.24
edit the file /etc/network/interfaces. Example below
auto eth0
iface eth0 inet static
address 192.168.139.50
netmask 255.255.255.0
gateway 192.168.139.1
network 192.168.139.0
broadcast 192.168.139.255
auto eth1
iface eth1 inet static
address 10.0.0.1
netmask 255.255.255.0Head node
Routing IPv4
- Add or uncomment the line net.ipv4.ip_forward=1 in /etc/sysctl.conf to allow Routing after boot
- Issue the command sysctl -w net.ipv4.ip_forward=1 to allow routing in flight.
NAT with iptables
#!/bin/bash
#
# Start firewall
#
# Tillader ping indefra og ud.
# Lukker for al anden trafik.
# Diverse erklæringer
FW=iptables
INT_NET="10.0.0.0/24"
EXT_NET="172.16.4.0/24"
EXT_IP="172.16.4.99"
EXT_IF="eth0"
# Fjern alle tidligere regler
$FW -F INPUT
$FW -F OUTPUT
$FW -F FORWARD
$FW -F -t nat
# Sæt default politik til afvisning
$FW -P FORWARD ACCEPT
# Tillad ping indefra
$FW -A FORWARD -s $INT_NET -p icmp --icmp-type echo-request -j ACCEPT
# Tillad pong udefra
$FW -A FORWARD -d $INT_NET -p icmp --icmp-type echo-reply -j ACCEPT
# Source NAT på udgående pakker
