these files cannot be opened.

These files can’t be opened. Your Internet security settings prevented one or more files from being opened.

I came across this today while trying to run an unsigned, potentially harmful executable. There are plenty of recommendations out there on the web on how to fix this, but I found the fastest solution to be as follows.

Open internet explorer and select internet options:

internet_explorer_settings

internet_explorer_settings

Next select the security tab then restricted sites:

internet_explorer_settings_security+restricted_sites

internet_explorer_settings_security+restricted_sites

Now Select custom level and in the new window scroll down and enable “launching applications and unsafe files(not secure)”:

internet_explorer_settings+security_settings-restricted-sites-zone

internet_explorer_settings+security_settings-restricted-sites-zone

Select ok and agree to the warning:

internet_explorer_settings+warning!

internet_explorer_settings+warning!

Now try to run your executable. If this still does not work try using the above steps on the internet, local intranet, and trusted sites zones:

internet_explorer_settings+main_menu

internet_explorer_settings+main_menu

Hope this helps!

How to: Setup Port Forwarding For SSH

Port forwarding will allow you to connect to your SSH server from anywhere, and it is really easy to do.

Requirements:

Administrator access to your router
Putty client

Step 1: Login to router

Login to your router via a web browser using its IP address (default is 192.168.1.1)

router browser login

Next you locate where you can setup port forwarding. In my case it is under  Applications & Gaming sub tab Single Port Forwarding.

Once located create a custom forward with the following settings:

Internal port: 22
IP address of your SSH server.

Save the settings.

port forward config router

Step 2: Get your external IP address

You can find your external IP address by visiting http://johnklann.com/getmyip.php

 *Note: Unless you have a static IP provisioned by your ISP, your external IP address will most likely change often. There are several services that allow you to track the change, and assign a domain name to it (Never had much luck with them). I went with a much more simple approach. View the article here.

Step 3: Creating your first external connection

From computer outside your LAN open your putty client.
Enter your external IP address into the Hosts field and click open.

putty setup ext ssh session
If you receive a popup box like the following select yes to continue:

rsa key working ssh
Enter your username and password:

ssh login
Then you will receive a shell on the SSH server:

secure shell on remote ssh server
