The sysstat package contains the sar, sadf, iostat, nfsiostat, cifsiostat, mpstat, and pidstat commands for Linux. The sar command collects and reports system activity information. The statistics reported by sar concern I/O transfer rates, paging activity, process-related activites, interrupts, network activity, memory and swap space utilization, CPU utilization, kernel activities, and TTY statistics, among others. The sadf command may be used to display data collected by sar in various formats. The iostat command reports CPU statistics and I/O statistics for tty devices and disks. The pidstat command reports statistics for Linux processes. The mpstat command reports global and per-processor statistics. The nfsiostat command reports I/O statistics for network filesystems. The cifsiostat command reports I/O statistics for CIFS filesystems.
KBACKUP is intended for handling of backups no matter whether they reside on disk or tape or even in files. As most other backup programs available today are either confusing the user with lots of long command line options, or user friendly but not powerful at all, the aim behind writing KBACKUP was to provide a user friendly yet powerful backup program. It is also intended to be kept compatible to existing and well proven archive formats, so you can restore your archives even if you should not have KBACKUP around anymore.
Dip handles the connections needed for dialup IP links, like SLIP or PPP. It can handle both incoming and outgoing connections, using password security for incoming connections. It has a command mode (an interactive program to set up an outgoing IP connection), dialout mode (interprets chat script to dial out and open an IP connection), and dialin mode (login shell for handling incoming IP connections, as in dialup SLIP and PPP connections).
Linux/IR is a project with the goal of implementing the IrDA protocol stack into the Linux kernel. IrDA is a standard for infrared communication between devices such as laptops, printers, PDAs, mobile phones, and LAN access points. LAN and printer support has been implemented, and the current release is quite stable. There are still a few problems. The IrDA layers that have been implemented are IrPHY, physical layer, stuffing and wrapping of frames, IrLAP, link layer, sliding windows and link access control, IrLMP, link management, multiplexing, IrIAS, information base, device discovery information, IrLPT, printer support, IrTTP, transport layer, flow control, IrLAN, LAN access, IrOBEX, and object exchange, so you can talk to your Palm III.
