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:
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.
