Which of the following is a rewrite of ipfwadm?
- ipchains
- iptables
- Netfilter
- ipcook
- None of the choices.
Explanation:
ipchains is a free software based firewall running on earlier Linux. It is a rewrite of ipfwadm but is superseded by iptables in Linux 2.4 and above. Iptables controls the packet filtering and NAT components within the Linux kernel. It is based on Netfilter, a framework which provides a set of hooks within the Linux kernel for intercepting and manipulating network packets.
