Problem:

macOS (14.2.1) ssh (OpenSSH_9.4p1, LibreSSL 3.3.6) is vulnerable to Terrapin attack (as reported by the scanner).
The regular OpenSSH (e.g. via Homebrew) doesn't support the UseKeychain option

Workaround:

Automator > new Application > Run Shell Script: ~/bin/login-script, save as Login script.app
Create a new file ~/bin/login-script with contents:

How to install game-porting-toolkit (aka proton for macOS)

You also might wanna just use Whisky which does this automatically

Updating expired GPG keys and their backup 🔑🔐💻

I use a GPG key to sign my git commits.

An error like this one might be a sign of an expired GPG key.

error: gpg failed to sign the data fatal: failed to write commit object

Installation

mkdir -p ~/.config && touch ~/.config/ssh-agent.pid
Paste the contents of ssh-agent-manage.sh into your .bashrc or .bash_profile or similar
killall -9 ssh-agent
Start a new terminal session (note: old sessions will not see ssh-agent, only new ones)

Details

This snippet, when included in .bashrc, will ensure that your session has a working ssh-agent with all your ssh keys loaded into it. It does this without creating separate ssh-agent processes by:

	#!/bin/bash

	LOG_FILE="chess_script.log"

	log() {
	echo "$(date '+%Y-%m-%d %H:%M:%S') - $1" \| tee -a "$LOG_FILE"
	}

	# Requesting sudo privileges at the start
	log "Requesting sudo privileges..."

	#!/usr/bin/env bash

	# checck if pidof exists
	PIDOF="$(which pidof)"
	# and if not - install it
	(test "${PIDOF}" && test -f "${PIDOF}") \|\| brew install pidof

	# find app in default paths
	CO_PWD=~/Applications/CrossOver.app/Contents/MacOS
	test -d "${CO_PWD}" \|\| CO_PWD=/Applications/CrossOver.app/Contents/MacOS

	#!/usr/bin/env bash

	# Setup automatic sync from a Github upstream repository to a fork
	# - a branch "actions" will be created (or re-used) to hold the Github action to run
	# - sync is done each hour
	# - branch 'actions' needs to be the default branch of your fork (=> settings)
	# - the script is able to both create and update and rewrite the sync script if you modify this script file
