## Project history and usage

mpssh, short for Mass Parallel Secure Shell, is a small parallel-SSH administration tool by Nikolay Denev. Its README carries a 2005-2015 copyright notice and describes the program as connecting to many hosts from a hosts file, running the same command on all of them, and prefixing each output line with the hostname that produced it. GitHub tags show the 1.0, 1.1, 1.2, and 1.3 releases in September 2012, a 1.3.1 tag in January 2013, and 1.3.3 in June 2014.

### Project history

The tool is deliberately thin: it executes the OpenSSH ssh binary directly, can scp a local script to each remote host before execution, supports per-host usernames and ports, host labels, output files, connection delays, and a configurable number of parallel ssh processes. It depends on existing passwordless authentication such as public keys or Kerberos rather than managing credentials itself.

### How it is used

mpssh sits in the old-school sysadmin niche alongside pssh, pdsh, and ad hoc shell loops: one command, many machines, minimal state. It is useful when the operator already has SSH trust configured and wants bounded parallelism, host-labeled output, and simple host grouping without adopting a configuration-management system.
