Parallel Processing i recently read an article about parallel processing. i remembered my domain checker service which checks a lot of domains for their availablitly, and this script runs sequentiel and needs around 30 seconds. initially i worked on a caching mechanism to speed up results. but if a service is not used that often (nobody is useing my domain checker…), there is not much you can gain with caching.

Intro this is a little script which reads the Name Servers for a given Domain, and then asks the NameServer for the SOA of this Domain. Script cat << 'EOF' > soachecker.sh #!/usr/bin/env bash # Little SOA & Serial Checker, v0.1, @stoege tmpfile=$(mktemp) # Check Args echo if [ $# -eq 0 ]; then d="stoege.net" echo -e "No argument provided. use \033[1m'${d}'\033[0m" elif [ $# -eq 1 ]; then d="$1" echo -e "Domain \033[1m'${d}'\033[0m provided" else echo -e "\033[1mmore than one arguments provided.

Certificate Management with ‘acme.sh’ I like to manage my certificates on my own. If you work with Wildcard Certs, acme.sh is a nice and flexible ACME Client, purely written in Shell. It’s probably the easiest & smartest shell script to automatically issue & renew the free certificates. Basic Handling Get Version acme.sh --version run it # acme.sh --version https://github.com/acmesh-official/acme.sh v3.0.6 Upgrade Self are we up2date ? acme.sh --upgrade run it
