IP traceback is any method for reliably determining the origin of a packet on the Internet. The IP protocol does not provide for the authentication of the source IP address of an IP packet, enabling the source address to be falsified in a strategy called IP address spoofing , and creating potential internet security and stability problems.
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.

iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. The filters are organized in a set of tables, which contain chains of rules for how to treat network traffic packets.
Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
TCP Wrappers (also known as tcp_wrappers) is a host-based networking ACL system, used to filter network access to Internet Protocol servers on operating systems such as Linux or BSD. It allows host or subnetwork IP addresses , names and/or ident query replies, to be used as tokens on which to filter for access control purposes.
The successor to NetWare, Open Enterprise Server, comes in two flavors: OES-NetWare, which provides legacy support for IPX/SPX (deprecated), and OES-Linux, which only supports TCP/IP. Both Microsoft and Novell have provided support (through Proxy Server/ISA Server and BorderManager respectively) for IPX/SPX as an intranet protocol to ...
Ubuntu is built on Debian's architecture and infrastructure, and comprises Linux server, desktop and discontinued phone and tablet operating system versions. [31] Ubuntu releases updated versions predictably every six months, [32] and each release receives free support for twelve months (eighteen months prior to 13.04) [33] with security fixes ...
