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 18.104.22.168), but has been greatly enhanced, ported and fixed and barely resembles the original package anymore.
Dante is a free implementation of the proxy protocols SOCKS version 4 and SOCKS version 5 (RFC 1928). It can be used as a firewall between networks, controlling outgoing traffic. The package consists of two parts: a socks server and a proxy client that supports socks, HTTP proxies, and UPnP. RFC 1961 (GSSAPI) is supported in both the client and the server. Commercial support is available.
CoralReef is a comprehensive software suite developed by CAIDA for collecting and analyzing data from passive Internet traffic monitors in real time or from trace files. The package also includes programming APIs for C and Perl, and applications for capture, analysis, and Web report generation.
The Spread Toolkit provides tools for developing reliable and robust distributed applications ranging from collaboration tools to fault-tolerant database servers to replicated Web servers. It consists of a daemon which provides multicast messaging, reliability, ordering, and membership services, and a library which applications link with. Spread provides a simple API for writing group applications and is designed to provide high performance for local and wide area networking applications.
NSH is a CLI intended for OpenBSD-based network appliances. It replaces ifconfig, sysctl, and route with its own simple command language, and consolidates configuration for other daemons into one place, effectively replacing /etc/netstart and parts of /etc/rc for appliance-style usage. NSH presents the user with a vaguely Cisco-like interface with all configuration in one easy to read text list. It also gives the user access to system information and diagnostics. NSH replaces the userland commands that handle these functions, and talks directly to the OpenBSD kernel or control utility for daemon functionality. Supported external utilities: pf, ospfd, ospf6d, bgpd, ripd, ldpd, relayd, ipsecctl, iked, rtadvd, dvmrpd, sasyncd, dhcpd, snmpd, sshd, ntpd, ifstated, tftp-proxy, ftp-proxy, tftpd, npppd, resolv.conf, inetd, smtpd, ldapd, and ifstated.
