syncpasswd is an Expect script that synchronizes passwords via SSH on multiple platforms (Linux/BSD, OS X, and Solaris). It takes hostnames as a list of arguments and changes the specified user passwords on those hosts. It outputs results to stdout and logs to /var/log/syncpasswd.log (by default).
synctool is a cluster administration tool that keeps configuration files synchronized across all nodes in a cluster. Nodes may be part of a logical group or class, in which case they need a particular subset of configuration files. synctool can restart daemons when needed, if their relevant configuration files have been changed. synctool can also be used to do patch management or other system administrative tasks.
sysXs is a control panel solution for enterprise use. It automates administration, accounting, and billing of Internet services using a Web-based interface suitable for any browser. It can be used on a wide variety of platforms. By implementing a flexible user management that includes customer self care functionality, it's not restricted to the classic vendor/reseller/customer scheme.
Sysinit is a system-initialization scheme for use with Linux and a daemon-management scheme for use with runit or daemontools. It provides a common interface to all functionality, and uses envdirs instead of sourced shell scripts or custom configuration files. It does error handling, handles dependencies gracefully and simply, and handles runlevels.
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.
systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts. It provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux cgroups, supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can work as a drop-in replacement for sysvinit.
Systeminfo is a shell script used to generate system information on RPM packages available, the system routing table, disk information, file system information, system general information, network interface information, kernel tunable parameters, system resource limitation for the current user, memory information, modules available in the Linux kernel, processor information, RAM available, services currently running, running process status, system uptime, currently logged in users, and virtual memory statistics. Report generation can take place in text or HTML format.
