Parallel SSH multiplexer designed for performing parallel map operations via ssh. Sshmap uses a hostlist module to determine hosts to operate on from a number of sources, it supports host names, dns/reverse dns, database backends and load balancers (haproxy). This functionality supports ... [More] recursion (dns gives a list of vips, which are then used to query the load balancers to get a list of hosts actually serving the traffic). Sshmap supports running a single command on a host or streaming a script to the hosts over the ssh connection and it can handle sudo authentication to run the resulting scripts using sudo privileges. The resulting data can then be handled in batch after completion on all hosts or asynchronously as the results come back via callback script pipelines. [Less]

Run multiply terminals in one terminal

gcsd the generic command sequencer daemon can be used to serialize commands sent over various paralell communication channels to a single command output. It can be seen as a multiplexer for any kind of communication between a single resource and various clients which want to submit commands to it or ... [More] query information from it. gcsd is written in C and Lua. The goal is to provide an easy to understand high level API based on Lua which can be used to implement the business logic of the so formed multiplexer daemon. [Less]
