Setting up a pipes between A and B

A to B (setup on A)

From A, set up a pipe for sending data from A to B

a@A: ssh -v -N -L 2223:127.0.0.1:2222 b@B

To test it, first open a listener on B

secure ssh copy to remote server

motivation

From machine A, user-A does an sshinto th eaccount user-B on server B for a terminal session.
In the course of that session, it would be convenient to copy some data to A's clipboard, without using mouse to drag and click. Example use cases:

1. cat files content into local clipboard. C.f., cat | xsel -i -b or cat | xclip -i -selection b

multi os booting with systemd-boot

We set up multiple OS to be booted from a UBS SD.

Both are Ubuntu.

• ub16 is on an LVM2 partition.
• ub18 is on an encrypted LUKS partition with LVM2 on the inside. As it happen, the disk is SSD.

Formatting the USB SD
