cpuburn is is a set of programs that load x86 CPUs as heavily as possible for the purposes of system testing. FPU and ALU instructions are coded in an endless loop in an attempt to maximize heat production from the CPU, putting stress on the CPU itself, the cooling system, the motherboard (especially voltage regulators), and power supply. The tests may damage undercooled, overclocked, or otherwise weak systems and cause data loss or permanent damage to electronic components.
dietsniff is a tiny tool for analyzing traffic on a network. It's not intended to replace well-known tools like tcpdump or ethereal. It's intended for the case when a small and especially static sniffer is required. Accordingly, it's also by far not that powerful, and is also bound to Linux as a platform. While it doesn't use or need the libpcap, it produces pcap-logs that can be analyzed by more sophisticated tools like tcpdump or Ethereal.
dstat is a versatile replacement for vmstat, iostat, netstat, nfsstat, and ifstat. It includes various counters (in separate plugins) and allows you to select and view all of your system resources instantly; you can, for example, compare disk usage in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).
FindFile will be a collection of tools for recovering files from filesystems with corrupted directories, allocation tables, etc. This can be useful when the partition table (or more) of a hard disk is corrupted, or when you have a memory card of a digital camera which is corrupted. For now, only a tool for recovering JPEG files is included.
i.Task is a small and fast process viewer and terminator for Linux. It lists all running processes and associated information, allowing the user to sort by any column. The information displayed includes, process name, PID, CPU usage/time, owner, priority, threads, memory usage and process arguments. The context menu allows you to send TERM or KILL signals to a process. The main benifit of i.Task, apart from the easy-to-use interface, is that it has far fewer dependencies that other available process viewers.
ICPLD (Internet Connection Performance Logging Daemon) is a connection monitor that sends ICMP requests to IP addresses of your choice and monitors if your machine has a working network connection. It logs failed attempts to reach the hosts, and will stamp a log as soon as a reply is received. It keeps track of when and for how long the connection was unavailable and records both total down time and each occasion of interrupted connection. It supports IPv6 and can execute a command whenever a connection goes up or down, which is useful for alerting users.
