ELF Format Cheatsheet

Introduction

Executable and Linkable Format (ELF), is the default binary format on Linux-based systems.

Compilation

zOrg1331

Intro

This note describes how to connect two networks/devices/VMs over public network using Wireguard with Layer 2 support (ARP, IPv6 link-local, etc).

This can also be achieved using SSH and its "tap" tunnel, however, it does not provide the same level of latency and bandwidth as full-blown VPN such as Wireguard.

In addition, this note describes how to tunnel Wireguard over TCP connection. This may be of use if you encounter firewall in-between so, for instance, you can use TCP port 443 only.

Background

This was created years ago; at the time I'd been a Shibboleth admin for nearly a decade but we needed something that could handle OIDC/OAuth and that explicitly supported OpenJDK. After a lot of investigation, I really liked Keycloak/Red Hat Single Sign-On. More details here: Gluu vs keycloack vs wso2 identity management
