Iperf was orginally developed by NLANR/DAST as a tool for measuring maximum TCP and UDP bandwidth performance. Iperf allows the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss. iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. iperf3 also a number of features found in other tools such as nuttcp and netperf, but were missing from iperf2.x. Some new features in iperf3 include: reports the number of TCP packets that were retransmitted reports the average CPU utilization of the client and server (-V flag) support for zero copy TCP (-Z flag) JSON output format (-J flag)
ipmievd is a daemon which will listen for events from the BMC that are being sent to the SEL and also log those messages to syslog.
This package contains a utility for interfacing with devices that support the Intelligent Platform Management Interface specification. IPMI is an open standard for machine health, inventory, and remote power control. This utility can communicate with IPMI-enabled devices through either a kernel driver such as OpenIPMI or over the RMCP LAN protocol defined in the IPMI specification. IPMIv2 adds support for encrypted LAN communications and remote Serial-over-LAN functionality. It provides commands for reading the Sensor Data Repository (SDR) and displaying sensor values, displaying the contents of the System Event Log (SEL), printing Field Replaceable Unit (FRU) information, reading and setting LAN configuration, and chassis power control.
The iproute package contains networking utilities (ip and rtmon, for example) which are designed to use the advanced networking capabilities of the Linux 2.4.x and 2.6.x kernel.
