crussh: a modern cssh replacement

Available via radicle at: rad:z3BhWhapyVBzzuBicAyCcmMhv1yEe

What are this?

For anyone who needs to administrate clusters of many machines, clusterssh has long been a fallback for when the rest of your automation tools aren't working.

crussh aims to be a simple replacement for cssh with the following improvements:

  • Uses a single window to hold multiple terminals.
  • Intelligently tiles terminals to fit available window size.
  • Scrolls available terminals when they don't all fit in-window.
  • Never resizes a terminal smaller than 80x24 characters.
  • Uses GTK and the VTE widget to provide modern, anti-aliased terminals.

Install

The install process is very simple on most distros:

  • Install python3 and python3-gi.
  • Clone and symlink to your bin dir:
git clone https://github.com/nergdron/crussh.git
ln -s $(pwd)/crussh/crussh.py ~/bin/crussh

Run crussh HOST [HOST ...]

Examples

Basic usage is covered via the builtin help, which you can get by running crussh -h. This section covers some common use cases.

To connect to a list of hosts in a file:

crussh $(cat hostlist.txt)

To use a custom login name, public key, or other SSH client options:

crussh -l someuser -i ~/.ssh/myotherkey -- host [host ...]

To do something other than ssh, such as edit a bunch of files in parallel:

crussh -e nano *.txt

Usage Tips

Doing a clustered paste isn't completely obvious. The following methods will work, after making sure you're clicked into the text entry box at the bottom of the window:

  • middle click or shift-insert to paste the X11 selection buffer.
  • control-shift-v to paste the GTK/GNOME clipboard.
