SSH Server with the Python Twisted Library

Installing the library

Assuming you have Python installed on your system:

pip install twisted
pip install pyOpenSSL
pip install service_identity

How to tunnel SSH over SSL/TLS

laptop ssh -> laptop stunnel -> evil network -> internet -> your server -> your server ssh

Server (your shell server/home box/work box/whatever)

Sets up a stunnel process listening externally on port 2443/tcp, forwards to localhost 22/tcp

Install stunnel, e.g. yum install stunnel
Install server config snippet to /etc/stunnel/stunnel.conf

OpenWRT on x86_64

This is a very brief tutorial on getting OpenWRT installed on a regular computer, it assumes you know your way around Linux. If you find this and need additional details, please like, subscribe, and comm... oh wait this isn't youtube, just comment.

This is how I got OpenWRT going on a Mini ITX Intel DH67CF with an Intel G870 CPU with 4GB of RAM.

What You'll Need

2 USB Sticks
Linux Live ISO

On the host

Ensure these modules are loaded

cat /proc/sys/net/bridge/bridge-nf-call-iptables

Disable swap

sysctl vm.swappiness=0
swapoff -a

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

	Few day ago we showed you how to install Webmin on Ubuntu 14.10. This brief tutorial is going to show you how to install the same Webmin on a CentOS 7 machine.

	For those who don’t know, Webmin is a web-based tool to mange every aspect of your Unix-like systems. From creating new accounts to managing file permissions to installing applications and services, Webmin allows you to perform all these tasks easily from any modern web browser.

	Instead of using the command line console or terminal, new systems administrators could install Webmin and perform all system management from via a web browser without sacrificing time and efforts. Webmin also enables remotely management of your servers.

	Before you continue with the installation, please make sure you have root level permissions to your system. If you don’t have root access the installation may fail.
