ngrok exposes local servers behind NATs and firewalls to the public internet over secure tunnels.

How it works

You download and run a program on your machine and provide it the port of a network service, usually a web server.
It connects to the ngrok cloud service which accepts traffic on a public address and relays that traffic through to the ngrok process running on your machine and then on to the local address you specified.

What it&#39;s good for

Demoing web sites without deploying
Building webhook consumers on your dev machine
Testing mobile apps connected to your locally running backend
Stable addresses for your connected devices that are deployed in the field
Running personal cloud services from your home

Netcat is a featured networking utility which reads and writes data across network connections, using the TCP/IP protocol.  It is designed to be a reliable &quot;back-end&quot; tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities.

ProxyCap enables you to redirect your computer&#39;s network connections through proxy servers. You can tell ProxyCap which applications will connect to the Internet through a proxy and under what circumstances. This is done through a user friendly interface, without the need to reconfigure any of your Internet clients. ProxyCap has native support for the SSH protocol, allowing you to specify a SSH server as the proxy server.

SSH Proxy can help you turn any remote SSH server into a SOCKS v5 proxy, intuitive and easy to use.

SSH Proxy is able to remember the SSH login password &amp; private key passphrase and save it to OS X&#39;s keychain. Furthermore, SSH Proxy is designed to automatically reconnect when your Mac is waking up from sleep.

Notable Features:

- Auto launch when log in OS X
- Ability to share SOCKS v5 proxy on LAN
- Create SOCKS v5 proxy through SSH tunnel
- Fast switch between multiple SSH accounts
- Automatically reconnect after disconnected by errors or waking up from sleep
- Remember SSH login password &amp; private key passphrase in OS X Keychain automatically
- Whitelist, only sites on the list will be accessed through the proxy server, other sites will be connected directly

SSH Functions:

- Support compressing SSH connection
- Support public key and password authentication methods
- Support RSA and DSA authentication identity (aka private key)
- Support connecting through SOCKS v5 / SOCKS v4 / HTTP proxy with authentication

Say Hello to Sidestep

The problem

When you connect to the Internet through an unprotected wireless network, such as at a coffeeshop or an airport, where you don’t have to enter a security key, you’re putting yourself at risk.

Attackers connected to the same network can easily intercept your unencrypted traffic and log in as you to services such as Facebook, Amazon, and LinkedIn.

Try this simple Firefox add-on to see for yourself how serious the problem is and how easy it is for your privacy and security to be compromised.

The solution

When Sidestep detects you connecting to an unprotected wireless network, it automatically encrypts all of your Internet traffic and reroutes it through a secure connection to a server of your choosing, which acts as your Internet proxy. And it does all this in the background so that you don’t even notice it.

With Sidestep enabled, no one can eavesdrop on your traffic and impersonate you or see what you’re seeing as you browse the web.

SSH Tunnel Manager is a tool to manage SSH Tunnels (commonly invoked with -L and -R arguments in the console). With SSH Tunnel Manager you can set up as many tunnels as you wish, each one containing as many port redirections as you wish. Once tunnels are configured, all you have to do is Start, or Stop the tunnels.

DNScapy is a DNS tunneling tool. The code is very light and written in Python. It includes a server and a client. The server can handle multiple clients.

DNScapy creates a SSH tunnel through DNS packets. SSH connection, SCP and proxy socks (SSH -D) are supported. You can use CNAME records or TXT records for the tunnel. The default mode is RAND, which uses randomly both CNAME and TXT.

DNScapy uses Scapy (http://www.secdev.org/scapy) for DNS packet forging and for his network automaton API.

DNScapy is still under development. The current version is 0.99b and seems to work pretty well. Feel free to clone and test it !

This is a python program that helps me to manage the SSH tunnels that I use regularly for secure remote connectivity to my office and home networks. The standard Ubuntu repository already contains a program for managing tunnels, but it did not meet my requirements, so I used this as an opportunity to learn PyGtk programming.

The program allows you to maintain a configuration of commonly used dynamic, local, and/or remote SSH port-forwarding tunnels. Once configured, the tunnels can be started and stopped with simple mouse clicks, or even auto-started when the program is launched. Both SSHv1 and SSHv2 tunnels are supported. SSHv1 support was the main issue that drove me to write my own program.

If you are using key-based SSH authentication for all of your tunnels (you are, aren&#39;t you? if not, then why not?), you can register your SSH keys with the tunnel manager, too. The keys can be loaded or unloaded with simple mouse clicks, or even auto-loaded when the program is launched. This means of managing the key agent is another big advantage for me over the existing alternatives.

Tunnel Manager allows users to easily manage a configurable list of SSH tunnels and their required keys.
