go-cluster-ssh: cssh replacement in go

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.

go-cluster-ssh 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 250x250 characters.
• Uses GTK and the VTE widget to provide modern, anti-aliased terminals.
• Group terminals
• Save and load groups

Install

The install process is very simple on most distros:

• Download binary from Release page

Run go-cluster-ssh -- HOST [HOST ...]

Examples

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

To connect to a list of hosts in a file:

go-cluster-ssh -f hostlist.txt

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

go-cluster-ssh -args="-l someuser -i ~/.ssh/myotherkey" -- HOST [HOST ...]
go-cluster-ssh -args="-l someuser" -args="-i ~/.ssh/myotherkey" -- HOST [HOST ...]

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

go-cluster-ssh -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.
