crussh: a modern cssh replacement
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.
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
crussh HOST [HOST ...]
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
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.
