    I’ve been using “gsh” for a couple years. Its a simple parallel SSH app, but its nice because, I can maintain only one hosts file, but specify multiple categories for each host, and mix and match them with simple booleans to get the execution list of hosts I desire.

    I’m using terminator and can broadcast commands to multiple modes/separate terminals

    /etc/anasible/hosts

    ansible

    Is there a tool like these but with an additional feature: instead of manually editing a “host” file, other computers would notify a server that they are available for ssh?

      @Sugar

      Some of these tools allow you to add the hosts on the command line, without necessarily using a hosts file. You can read their man pages for more information.

    Xcat project spawned psh and dsh. Older version of psh had an option to use nodelist.tab file that contained:

    Host01 group1,webserver,rhel7
    Host02 group1,appserver,rhel6
    ....
    

    Psh. Group1 uptime

    Would run on both

    Psh rhel6 uptime

    would run only on host02

    Each server is listed once, not i. 10 different files.

    Later xcat switched to a db format for hosts, but was more complicated.

    Loved that nodelist.tab simplicity.

    Thanks for the article! Always looking for more options to perform similar tasks.

    When you want to interact with multiple hosts simultaneously, MobaXterm (mobaxterm.mobatek.net), is a powerful tool. You can even use your favorite text editor (vim, emacs, nano, ed) in real time.

    Each character typed is sent in parallel to all hosts and you immediately see the effect. Selectively toggling whether the input stream is sent to individual host(s) during a session allows for custom changes that only affect a desired subset of hosts.

    MobaXterm has a free home version as well as a paid professional edition. The company was highly responsive to issues reports that I provided and corrected the issues quickly.

    I have no affiliation with the company other than being a happy free edition customer.
