NetSplitter 20021204

NetSplitter is a ( user-level ) network load-balance. It is like a transparent-proxy and will balance ( output ) TCP connections on multiples links. Linux NAT add/remove code is incomplete. NetSplitter will use the system() function to run the iptables to handle this. Step 1) IPTABLES Tell Iptables redirect packets. netfilter will intercept the data. iptables -t nat -A PREROUTING -i eth0 -p tcp -s 192.168.2.0/24 -j DNAT --to-destination 192.168.2.1:5122 Or use any rule you want. just like a transparent proxy to proxy 5122. eth0 is the LAN interface 192.168.2.0/24 is the LAN address 192.168.2.1:5122 is the netsplitter address and port. !! DONT FORGET TO ADD UDP AND ICMP NAT CONFIGURATION !! - OPTIONAL LOCAL-NAT In your iptables rulez: iptables -t nat -A OUTPUT -p tcp --sport 1024:4999 -j DNAT --to-destination 192.168.1.1:5122 where 1024-4999 are the values in /proc/sys/net/ipv4/ip_local_port_range. and 192.168.1.1 is the netsplitter address. Step 2) File Configuration Config File: /etc/netsplitter.conf INTERFACE eth0 200.161.76.110 256 INTERFACE eth1 200.212.76.185 256 INTERFACE eth2 200.200.200.200 256 PING 1.1.1.1 PING 2.2.2.2 where: [eth0] is a internet network link [200.161.76.110] Is the eth0 network address. [256] link speed, in kbps. [1.1.1.1] [2.2.2.2] A IP address that response to ping. NetSplitter will use this to check if a link is up or down. Whats New in This Release: - 20021115 - Linux and BSD working.
