Things to See in South Africa: Old English Fort and the Cogmanskloof Tunnel to Montagu Photo Gallery | Travel Attractions 28 JUL 2015

The Cogmanskloof Pass connects the towns of Ashton and Montagu. Its entire 6.5 km stretch through a majestic landscape of towering rock formations. Renamed after Cape Colony secretary, John Montagu, the town’s original name of Cogmanskloof is where this pass took its name from.

The original route through the mountain included two fairly dangerous river crossings (Kingna River), and so following a few disasters, famed road and pass builder Thomas Bain was commissioned to build the pass through Cogmans Kloof in 1877.

Using a combination of dynamite and gunpowder (gunpowder because dynamite was apparently relatively new and they quickly ran out of supply), Bain and his team ‘dug’ (fine, blasted) through the Kalkoenkrans and opened the route in 1879.

The unlined tunnel is 16 metres long, and has a five metre high arched roof.

The tunnel is the oldest solid rock (unsupported by concrete) road tunnel in South Africa.

(Thomas Bain’s father Andrew Bain, actually built the very first tunnel along the western ascent of Bainskloof Pass near Wellington in 1835, but that collapsed during construction so it doesn’t count)

At the top of the tunnel, blink and you will miss it, is the remains of a well camouflaged English fort (declared a monument in 1999), accessible via a short little hike starting to the right of the tunnel entrance, heading towards Ashton side.

Taken from the Internet: “1899 heralded the Second Anglo Boer War and saw the construction of the English Fort above Cogmans Kloof. This was built by stonemason William Robertson at a site selected by Lieutenant Colonel Sidney, Commandant of the Royal Field Artillery. The fort was garrisoned by a company of the Gordon Highlanders who were survivors of the Magersfontein battle, commanded by a Lieutenant Forbes.

They were camped on the original road construction site below Kalkoenkrans (Turkey Crag) the site which is now the parking area below the fort on the Montagu side.

The fort measures 9,3 x 3,8 m on the outside. It has a simple entrance opening at the west end and 21 ‘waisted’ loopholes formed in the masonry without steel plates. The loopholes are 700-800 mm above the concrete floor and the 400 mm thick stone walls reach a height of about two metres inside the building.

Inside the fort, near the south-east corner, is a roughly circular mortared stone platform (400 mm high), together with a drainage channel and hole at the base of the adjacent east wall, which seems to indicate the presence of a water tank and hence a roof.”

Joke Factory: American Slapping Jokes & other Funny Stuff 08 MAR 2013

An elderly lady, an attractive big boobed blonde, a noisy American and a Canadian guy were all seated on a train passing through a particularly mountainous area. As they passed through a pitch black tunnel, a loud *SLAP* broke the silence, and as the train emerged from the tunnel and into the light, there sat the American with a bright red hand print across the side of his face.

The old lady chuckled and thought to herself, “That noisy guy probably grabbed the blonde’s breast and she slapped him!”

The blonde thought to herself, “Ha, that guy probably tried to grab my breast, missed, and then caught the old lady’s breast by mistake. Wow, she really gave him a good wallop!”

The America thinks, “Geez, that Canadian probably tried to grab the blonde’s breast, she missed slapping him, and caught me instead!”

The Canadian guy sits there with a smile on his face, “Man, I can’t wait until another tunnel so that I can slap the crap out of this American again!”

Ubuntu: How to Setup a SSH Tunnel via a Terminal CodeUnit 26 OCT 2012

SSH tunnels are useful beasts in that they allow you to communicate with machines and ports on a private network which are not directly accessible to the external world, by building a bridge between your local machine and a machine in the walled off network to which you happen to have SSH access to.

The diagram below shows you an example whereby to gain access to a Oracle server on Port 1521, you would first SSH into a linux box on the inside network and then create a SSH tunnel which would transport traffic between your machine and the Oracle server.

Another example could be if you have MySQL installed on your server but have cut off external access to the database server, leaving only SSH open. In this case, you would connect into the box via SSH and create a tunnel to the MySQL database server on localhost port 3306.

To create a SSH tunnel is fairly simple and can be created with this command:

ssh -f remote-server.net -p 22 -l myusername -L 3307:localhost:3306 -N

The line above first connects to remote-server.net via SSH on port 22 using the user name ‘myusername’, and then sets up a SSH tunnel connecting port 3307 on your local PC (i.e. 127.0.0.1) and hooking it up to port 3306 on the remote-server.net box itself. Of course you could have created a connection to any other box that remote-server.net has direct access to.

You should be prompted for a password when running this command. Note that the -f switch means that this process will be started in the background and the trailing -N instructs OpenSSH not to execute the command on the remote server.

Nifty.

Ubuntu: MySQL SSH Tunnel via the Terminal CodeUnit 04 FEB 2011

If you have a closed machine that doesn’t allow MySQL connections from the outside world but does allow SSH access in to the box, say hello to the world of SSH tunneling.

The concept is simple. Bind one of your local machine’s port via a SSH connection to another box on the outside. For example:

ssh -N -L 3307:127.0.0.1:3306 userName@remoteHost &

The above is simply linking the remote machine’s MySQL server on port 3306 to your local machine’s port 3307. In other words, you can now connect to the MySQL server on the remote machine by connecting to localhost:3307.

Nifty.
