Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

I used to think that

ssh -X me@some.box

"just bloody worked". However this might not work - ssh must play ball on both sides of the link. On the remote (ssh server, X client) sshd must sit behind some port, tell Xlib to send X11 requests to it and then forward them back to you the X server (where the ssh client is). If the remote box is locked down to prevent this, you will get:

X11 forwarding request failed on channel 0

as part of an otherwise working login. As it happens, I am the admin of the remote box in question, so I followed the ArchWiki and went to /etc/ssh/sshd_config and uncommented

Multi Link Example for http://www.robschmuecker.com/d3-js-drag-and-drop-zoomable-tree/#comment-6190

Added an additional link between nodes at the bottom of the dndTree.js file.

This example pulls together various examples of work with trees in D3.js.

The panning functionality can certainly be improved in my opinion and I would be thrilled to see better solutions contributed.

One can do all manner of housekeeping or server related calls on the drop event to manage a remote tree dataset for example.
