Description of MyEnTunnel 3.4.2.1

A background SSH tunnel daemon

MyEnTunnel is a simple system tray application (or NT service) that establishes and maintains TCP SSH tunnels. It does this by launching Plink (PuTTY Link) in the background and then monitors the process. If the Plink process dies (e.g. connection drops, server restarts or otherwise becomes unreachable) MyEnTunnel will automatically restart Plink to reestablish the tunnels in the background. It tries to use as little CPU and system resources as possible when monitoring (When the "Slow Polling" option is enabled it only does one context switch per second).

Since it uses Plink, you can use utilities such as Pageant (a SSH authentication agent for PuTTY, PSCP and Plink) and PuTTYgen (a RSA and DSA key generation utility), as well as named PuTTY sessions. All of the networking and encryption is done by plink.exe; not by MyEnTunnel.

Editor's review for MyEnTunnel

If you’re in a situation where you need to constantly keep an SSH connection active, and you don’t want to go through the hassle of reconnecting when anything goes wrong on your end or the remote server becomes unreachable, MyEnTunnel is an excellent alternative.

As you might expect, the program is very simple. Once you run it, it sits in your system tray and monitors your SSH connections. If they drop out for any reason, MyEnTunnel will restart them. It uses PuTTY, the popular SSH client, to establish each connection. It then monitors the Plink process for any error conditions and terminations. The goal is to maintain a constant connection and to smoothly restart the process in the background whenever there’s a problem. When this happens, you won’t notice a thing. MyEnTunnel is coded to minimize CPU time, only performing one context switch per second when the Slow Polling option is selected.

MyEnTunnel has several options for managing SSH connections. You can choose to launch Plink at startup and establish the connection as soon as your PC starts; enable ZLIB link compression; tell it how many times it should try reconnecting; whether or not to always try to maintain the tunnel; how long to wait between reconnection attempts; whether to use a private key file to enable public/private key authentication; whether to enable dynamic SOCKS support; how much information to show in the status window; and whether or not to show notification popups. All the options are straightforward, and they do about what you’d expect.

If you plan to use your SSH tunnel to stream large amounts of data, such as videos, you’ll want to download the development version of Plink.exe, which handles bandwidth-intensive applications much better than the stable version. You’ll notice a huge difference if you’re making large file transfers or are otherwise using a lot of bandwidth.

MyEnTunnel has a stable version that does not use the Unicode character set and an alpha version that does. The author is currently looking for people to help him test the Unicode version. It already has language packs for several languages, including German and Simplified Chinese. The author makes it very simple to add language translations to the program, so if you have a mind to, you can submit a text file with the translations to the author, and he’ll make it available in the translations section.

MyEnTunnel was written by an author who really cares about people’s success with his software. It’s easy to contact him should you run into any problems getting MyEnTunnel and Plink to play nice together. You can also use other utilities that work with Plink such as Pageant to authenticate SSH connections and PuTTYgen to generate various kinds of encryption keys.

MyEnTunnel is a simple, effective program that performs its function well. In short, it stays out of the way, does its job, and if everything’s working correctly, you won’t even notice it’s there. This is exactly what you want out of an SSH tunnel daemon.
