SSH agent forwarding and screen

When connecting to a remote server via SSH it is often convenient to use SSH agent forwarding so that you don't need a separate keypair on that server for connecting to further servers.

This is enabled by adding the

ForwardAgent yes

option to any of your Host entries in ~/.ssh/config (or alternatively with the -A option). Don't set this option in a wildcard Host * section since any user on the remote server that can bypass file permissions can now als use keys loaded in your SSH agent. So only use this with hosts you trust.

	#!/bin/bash

	loopdevice=/dev/loop0
	loopfile=crypt.loop

	#megabytes
	loopsize=256

	#/dev/mapper/xxxxx when open
	cryptmapper=myCrypt

	# make sure crypt module in use
	sudo modprobe dm-crypt

	# Find out which drive it was with the following command:
	sudo fdisk -l

	# You must mount /dev/sda3 myvolume
	# use cryptsetup, device is accessible under /dev/mapper/myvolume
	sudo cryptsetup luksOpen /dev/sde3 myvolume
