# This installs a PXE boot server.
#
# It's based on https://help.ubuntu.com/community/DisklessUbuntuHowto.
# It's been used with ubuntu-10.10-server-amd64.iso and ubuntu-10.10-server-i386.iso.
#
# It requires two network cards. One for access to the outside world and one
# for a private network of PXE clients. I've choosen this setup to not cause problems
# with DHCP on the normal network.
#
# It also requires that you have a second partition mounted on /nfsroot.

Alternative/Secondary/Backup SSH Service:


Add this line to /etc/services
ssh-alt         10022/tcp   # ssh-alternative
You may change the port to any unused port you like but maybe try to avoid 2222 and 22222 as they are a little too obvious. This line actually specifies which port your alternative sshd will be listening on.

Save the launchd item following as as /Library/LaunchDaemons/ssh-alt.plist

Load with

Fenced code blocks inside ordered and unordered lists

1. This is a numbered list.

2. I'm going to include a fenced code block as part of this bullet:

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...

A script to query the Amazon Web Services usage reports programmatically.

Ideally this wouldn't exist, and Amazon would provide an API we can use 
instead, but hey - that's life.

Basically takes your AWS account username and password, logs into the
website as you, and grabs the data out. Always gets the 'All Usage Types'
