TipRPC provides a fast, easy syntax for RPC among C++ programs. It supports calling remote functions as if they were local, registering multiple handlers for incoming calls (multicast, essentially), overriding the same RPC function name by differing arguments, fast packaging up of arguments and return values, conversion of data as needed before transport, and template specialization for packaging up new data types. Various transports are supported, including TCP/IP (IPv4 and IPv6), UNIX domain sockets, and memory sockets.
SpotSec Network Gateway is an all in one Linux firewall and gateway distribution that features a Web-based management console. It is designed to be a unified threat management system to protect and defend a network. Common features include intrusion detection and prevention and HTTP, SMTP, and POP3 proxies with content filtering and virus scanning. The design of the Web interface is centered around the definition of networks, services, users, and time events, which allows easier modification of packet filter rules.
DhcpdByPort is a Perl script to generate ISC dhcpd configurations to assign IP addresses on a per switch port basis, like in a hotel environment where each room (socket) must always be given the same IP. Layer 3 ACLs for recent layer 2 Cisco switches are also generated to enforce the given IP address usage as a source IP.
