You can share parts of a secret with multiple people, so only some of them need to agree to see the secret.

Install ssss, then decide on the total number of secrets (N), and the threshold of people who must share their shard of the secret in order to reveal the secret.

1N=5
2T=3

A soft link is a file which says how to go to another file. When a program encounters a soft link, it will make a guess at whether it should ignore it, or try to get to that file.

To make a soft link to a file in the current directory, linking is easy:

1fortune > $file_1
2ln -s $file_1 $link_1

Now imagine your …

http Setup

In this example, the port used is 23231, but it can be anything. Open /var/lib/soft-serve/data/config.yaml and make sure the http section looks like this:

 1# The HTTP server configuration.
 2http:
 3  # The address on which the HTTP server will listen.

 6  # The path to …

Work with a database:

1sqlite3 "$FILE".sqlite3

Basic ssh

Try out basic ssh by accessing git.charm.sh, without needing authentication:

1ssh git.charm.sh

Start an ssh server to try it out. The ssh server is sometimes in a package called openssh, and sometimes only in openssh-server.

Once it's installed, check it's working:

1sudo systemctl status ssh

If that doesn't …

1. Install fdroid on phone.
2. Install termux.
3. Open fdroid, and run:

1pkg upgrade
2pkg install busybox termux-services openssh openssh-sftp-server
3source $PREFIX/etc/profile.d/start-services.sh

openssh-sftp-server will mount the phone's file-system, and show you some directories in ~/storage/.

4. Copy your PC's ssh public …

Mount a remote filesystem locally with fuse-sshfs:

1sshfs *user*@192.168.0.10:/home/*user* /tmp/mnt

Unmount with:

1fusermount -u /tmp/mnt

Set it up on /etc/fstab with:

1sshfs#bkp@bkp.a-server.ninja:/media/store1/bkp /backup fuse defaults,allow_other,reconnect,delay_connect 0 0

Make image backup of sda1 and sda2 from …

Mount

1sshfs $USER@$IP_ADDRESS:$DIR

Various flags:

• Encryption: -C
• Map between local and remote user UIDs: -o idmap-user

Unmount

1fusermount3 -u $DIR

List Services

All possible services are in:

1ls /etc/sv

The computer only uses those in /var/service, so symbolic links are made to start and stop services.

1ls /var/service

Start Services

Enable the sshd service, so that ssh will work every time you boot up:

1sudo ln -s /etc/sv/sshd /var/service

Then start the …
