ISPConfig 3 Web Forwarding

My mail and web host is in the process of upgrading his control panel software along with putting in a new server.

I struggled to find documentation for what I wanted to do with the new software. There is a very limited amount of documentation on the following site:
http://docs.ispconfig.org/

It did not cover my requirement for very simple web forwarding.
The DNS server for my domain is hosted on this new server but my blog is hosted elsewhere.

The following screenshots show examples of the settings I needed to enter to get web forwarding to work to a Google Blogspot site. They may not be the only way, nor the best but they worked today:

Create the DNS zone first

Beware of web browsers caching and of DNS refresh times, particularly the Time To Live (TTL.)

Add a CNAME for the sub-domain you want to forward
Watch out for the final dot in the host names in the DNS records data column. Without the dot the host is treated as a sub-domain and appended to the root domain of the zone. You'd get 'isp1.refinitive.com.anewleaf.org.uk' instead of 'isp1.refinitive.com'

I set the TTL to be 5 minutes while testing but Chrome cached the incorrect web site. I needed to clear the browsing history before I could see the changes working.

Add a top level web site

Add an alias to redirect to any other URL

This was all trial and error, hence these instructions.

I believe, but I'm not confident that the abbreviation R, in the above, means redirect and the L means don't process any further rules on that host name. Anyway the example I based this on suggested always using the R,L type.

The following bit is only necessary if you want to redirect the root domain to a web site.
For example: http://anewleaf.org.uk to got to http://www.anewleaf.org.uk

Settings on the site Redirect tab
Like the alias forwarding you also need a CNAME record in the DNS for the host, in this case 'www'.

Track and Cars

I've found the time to work on both my track and my model Land Rover Discovery 2.


I've been gluing in the windows of the Discovery. Yet again, I was not happy with the first attempt at gluing in the windows. I removed that attempt, trimmed it up and refitted more flush with the body.


I've also added a black border round each glass panel.


I used a long wooden stirring stick to put small drops of canopy glue along the edges of the clear plastic window inserts.







On the track I added another tyre wall where cars tend to drift out and hit a barrier very hard.

Outside In

I have just started fitting the windows to the model Discovery. I have only put in two windows so far but I have already decided that I should have designed them a different way.


I would have got more realistic results if I had created the body with a slight inset lip round most of the window frames. I could then have stuck the windows on, individually, from the outside. That would be exactly like the real vehicle.

The vacuum formed windows are forced in to a slight curve, even though the mold is sharp, so they cannot fit truly flush with the body. If they were formed as curves without the inset and there was an edge to fit them to, I am sure I could cut them to an exact fit with the pillars.

I will complete the model as is and get as close as I can but for any future models I'll do the windows another way.

In go the lights

It's taken quite a bit of cutting and filing to get the rear lights of the model Discovery 2 to the shape needed.


They are 3D printed but at such a tiny size the quality of the 3D print is too poor for them to fit properly. I have a single filament printer so the red and amber are printed separately and glued together.


They still need some work to finish them off. The plan is to coat them in a very thing coat of clear resin to give a gloss finish.


Dumper Pull

Our neighbour, Lee, called on Saturday to see if we had a winch to help move a dumper truck that had been left un-driven for such a long time that it had seized. It needed moving out of the way before his new kennels arrive.


He expected me to have an electric vehicle mounted winch. That's not what I have. It is surprising that is not one of the toys we have ever added to our Land Rover. The vehicle mounted winches look good but I personally think the manual portable winch is more versatile. It has done every job I've asked of it, with ease.


I have a Tirfor(r) type wire rope hoist with a pulling capacity of 2,400 kg. It normally lives in the back of the Discovery but I had the foresight to remove it before it went in for it's engine overhaul.



The dumper needed to be moved up a steep bank to get it close to the fence. This is so Lee could bring a lorry with a crane close enough to lift it over. We had to pull from the other side of the fence.


We used Lee's Range Rover to pull against. With a couple of easy pulls from different angles we were able to rotate the dumper and get it up the slope.



The manual wire rope hoist is slow but it feels under control at all stages because you only move the load an inch at a time.

Engine Water Ingress

Well, our poor car is off to get a reconditioned engine.



At least we know the cause, this time. It is the air filter housing.
The raised air intake (snorkel) was pointless because, unknown to us, the air filter did not fit the housing properly and water was sucked in from under the bonnet.



It is evident, if you open up the air filter.


The mud from the last outing is obvious.

The previous owner had fitted a high performance lifetime air filter, so it was rarely looked at. It also never occurred to me that it might be less suitable for off-roading.
We will be going back to a standard Land Rover filter.

This got me thinking.
Why don't engines designed for off-road use have a pressure release valve to avoid Hydrostatic Lock (Hydrolock) caused because water does not compress but air does!


To my mind it would be a fairly easy design.
Just an idea.

Said in Jest

One of my favourite work related bits of humour is about an engineer and a manager.
Normally this is in written form. I have been looking for a cartoon version for many years. There are a couple but none quite in the style I wanted.

I eventually created this myself.
The text and the clip art are all other people's. All I did was put it together.
Click on any image on this page to get a larger view so you can read the text.


The above style is to complement another cartoon joke that many will recognise.  I do not know who the author is but they have done an excellent job. I keep a copy of this handy to remind myself and others to keep things simple when managing projects.


Lastly for today, while looking for the text of the manager's joke, I came across another engineering funny. Again, I do not know the original author but many thanks for the laughs.
This particularly applies to the repair of Land Rovers.


I hope you enjoy this little selection.
