Trinux is a minimal Linux distribution that boots from a single floppy or CD-ROM, loads its packages from an FTP/HTTP server, IDE filesystem, or additional floppies, and runs entirely in RAM. It contains the most comprehensive set of network security tools available in any Linux distribution and can be used to conduct security research, analyze network traffic, and perform vulnerability testing of networks and applications.
The NET-SNMP (formerly UCD-SNMP) package contains various tools relating to the Simple Network Management Protocol including an extensible agent, an SNMP library, tools to request or set information from SNMP agents, tools to generate and handle SNMP traps, a version of the unix 'netstat' command using SNMP and a Tk/perl mib browser. It was originally based on the Carnegie Mellon University SNMP implementation (version 220.127.116.11), but has been greatly enhanced, ported and fixed and barely resembles the original package anymore.
The Periodic Remote Job Agent rjobs automatically sets up a PPP connection to another workstation and exchanges scripts containing job requests for the local and remote workstations. The usual method is to run rjobs as a cron job with specified weekday and weekend schedules, although "rjobs" can also be called in any other form or manner, as with any stand-alone application. Uses: E.g. control your home workstation from work without hogging the home telephone line.
ypbind-mt is a multi-threaded implementation of a NIS binding daemon. ypbind-mt compiles and works on Linux with glibx 2.x (libc6). It should work on every System with POSIX threads and glibc 2.x. It works under Linux with libc5 and linuxthreads 0.7.1, but this C library isn't really thread safe and shouldn't be used with threads.
The Network Information Service (NIS) provides a simple network lookup service consisting of databases and processes. It was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same, only the name has changed. Its purpose is to provide information, that has to be known throughout the network, to all machines on the network.
ntopmg is a network probe that shows network usage in a way similar to what top does for processes. It acts as a Web server, creating an HTML dump of the network status. It sports a flow collector, an HTTP-based client interface for creating ntop-centric monitoring applications, and RRD for persistently storing traffic statistics. Its C++ core can be scripted in Lua, for changing the appearance and extending functionality.
tcp_server is a simple, easily configurable tcp server for serving up multiple 'servlet' like processes. The servlet's can be extremely simple: No socket handling is required for the servlet, all it needs to do is read from stdin, and write to stdout. See the README for more information.
DeleGate is a multi-purpose application level gateway or proxy server that mediates communication of various protocols, applying cache and conversion for mediated data, controlling access from clients, and routing toward servers. It translates protocols between clients and servers, converting between IPv4 and IPv6, applying SSL (TLS) to arbitrary protocols, merging several servers into a single server view with aliasing and filtering. It can be used as a simple origin server for some protocols (HTTP, FTP, and NNTP).
