Linux Bonding

BotHunter가 interface 1개만 감시할 수 있어서

두 개 interface를 동시에 감시하기 위하여 bonding을 했다.

 

eth4와 eth5에 monitoring tap을 통한 트래픽이 오고 있는 상태였고

promisc 설정이 되어 있었다.

/etc/sysconfig/network-scripts
에 있는 ifcfg-eth4와 ifcfg-eth5를 수정
ifcfg-bond0 만들고
/etc/modprobe.conf
를 수정하는 스크립트를 고맙게도 누가 만들어놔서 적절히 사용했다.

 

#!/bin/bash
set -x
# 1: Create a bond0 configuration file
touch /etc/sysconfig/network-scripts/ifcfg-bond0
echo “DEVICE=bond0
IPADDR=192.168.x.x
NETWORK=192.168.0.0
NETMASK=255.255.255.0
USERCTL=no
BOOTPROTO=static
ONBOOT=yes” > /etc/sysconfig/network-scripts/ifcfg-bond0

# 2: Modify eth4 and eth5 config files:
echo “USERCTL=no
MASTER=bond0
SLAVE=yes” >> /etc/sysconfig/network-scripts/ifcfg-eth4
echo “USERCTL=no
MASTER=bond0
SLAVE=yes” >> /etc/sysconfig/network-scripts/ifcfg-eth5
sed -i ‘s/ONBOOT=.*/ONBOOT=yes/g’ /etc/sysconfig/network-scripts/ifcfg-eth4
sed -i ‘s/ONBOOT=.*/ONBOOT=yes/g’ /etc/sysconfig/network-scripts/ifcfg-eth5
sed -i ‘s/BOOTPROTO=.*/BOOTPROTO=static/g’ /etc/sysconfig/network-scripts/ifcfg-eth4
sed -i ‘s/BOOTPROTO=.*/BOOTPROTO=static/g’ /etc/sysconfig/network-scripts/ifcfg-eth5

# 3: Load bond driver/module
echo “alias bond0 bonding
options bond0 mode=0 miimon=100″ >> /etc/modprobe.conf

# 4: Test configuration
modprobe bonding
service network restart
sleep 2
cat /proc/net/bonding/bond0
echo ” ifconfig for bonding”
/sbin/ifconfig | grep bond
