EmSniff is an application that helps you to capture network packets. It differs from TCPDump in that it runs as a service instead of an application. This makes it possible to capture packets in the background. This can help applications like Wireshark to be more secure since they don't have to run with root privileges anymore. They only have to connect to the EmSniff server via libemsniff.
Ramon is an RMON2 network monitoring agent, as standardized in RFC-2021. There is a module suitable for loading into Net-SNMP via dlmod, so that the data generated by the agent is accessible. The following groups are functional: alHost, alMatrix, hlHost, hlMatrix, nlHost, nlMatrix, protocolDir, and protocolDist.
lando is a command execution system for UNIX. It allows you to run commands as a particular user from somewhere else on your network and see the output on your local machine. It supports authentication via standard /etc/passwd, shadow passwords or PAM. Access control is provided by TCP Wrappers. At present, the only client available is for Win32.
