18U Open Frame Server Rack (part 1)

My last post was about the 6U network cabinet I was using up until recently, I found a great price on an adjustable depth 18U open frame rack that was going to fit everything that I’m currently using and still have space to expand going forward. So, what’s changed since the last update? Well, quite a bit! The biggest item is a Motorola Quantar P25 repeater and some items to tidy up the ethernet cabling by including a 48-port patch panel to go with the 48-port PoE+ switch and a 1U cable management.  Most of the items that were previously in the cabinet are still on the 1U shelf but have been cable tied in place.   

So why did I go from using a network cabinet to an open frame rack? Well two reasons, the first being that I ran out of space in the 6U cabinet! also, the depth of the cabinet couldn’t take devices greater than 350mm in depth, and once I moved over to a 48 port PoE+ switch, it would not fit inside the cabinet as it’s 420mm depth. The other reason was heat, even though there’s plenty of ventilation slots you need a fan to move the warm air out of the cabinet. So I solved the heat issue by moving to an open frame rack as there is no places for warm air to pool and over time raise the temperature of the devices in the rack.

Naturally, this is still a work in progress so it will change as I add or remove items. 🙂

Medium plugin

I’m new to medium, well actually I’ve only made one posting, that was only to check that I have cross posting from medium to WordPress disabled. Ok the purpose of this post is to make sure that it’s enabled the other way!

It appears that I didn’t have it setup correctly but I think that’s been resolved…

Gremlin in the Server!

Over the last few days I’ve noticed that my web server has been a little unreliable. As usual there’s nothing obvious in the logs to recommend just what the cause might be. I’ve made some changes via ISPConfig and it’s possible that I may have set up something wrong! as GoogleBot has complained that it can’t reach the robots.txt file (this is in the root of the web server and is visible to me) So there’s a gremlin hiding here somewhere!

Gremlin

This is also effecting my mail server, So the occasional mail is bouncing (inwards) I just hope that this isn’t the beginning of a failing SQL table…

Speed Cameras

TASMANIA Police has denied new speed cameras do not work effectively because of design defects.

Reports today claimed the mobile laser speed camera’s effectiveness was limited because it could not work properly through protective glass covers.

But Inspector Mark Beech-Jones said the cameras were working fine and would work even better when upgraded.

“They are capturing and detecting people speeding. When they were launched last week, they caught someone speeding. Yesterday the one in southern region photographed 2000 cars,” he said.

He said the cameras had a range of 70m. But by replacing the perspex covers, their range would increase to 110m.

“The cost to change the perspex will be under $500 in total. It’s only a piece of perspex we’re changing to improve the range.

“There’s nothing wrong with the equipment. There’s nothing wrong with the trailer.”

The cameras were mainly used in urban settings, where range was not a critical issue, he said.

Inspector Beech-Jones also rejected suggestions the camera mounts were on the wrong side of the trailers, saying there were four mounts in each and the operator could move the camera depending on the road and conditions.

Three mobile laser speed camera trailers were launched last week.

They were funded by the Motor Accidents Insurance Board to the tune of $42,000.

Two Week Lenses

Today I received my first pairs (yes I meant two!) of biweekly contact lenses. Since I started with contacts, I’ve been using the daily disposable type. This has meant that I have not had the routine of cleaning the lenses after each use. So this is where the fun begins! 🙂

The type of cleaning option that has been selected for me is one that uses Hydrogen Peroxide to make sure that if any bugs decide to take up residence on the lenses that their life won’t be very pleasant! This may sound strange that you would use such a strong chemical that it alone can cause problems if misused, However in my circumstances the contacts are being used as a bandage as well as for corrective vision.

The amount of correction has changed frequently as the surface of my corneas has been healing, but it seems to have settled for the moment. With correction my eyesight is pretty much back to normal, but there’s still moments of a  slight haze but this is only apparent in bright light. It was horrible when it was (for a time) this was my normal vision.

Site Update Randomness

Yesterday (30th November) I rebuilt this server due to a slight problem/mistake that I caused when attempting to install ISPConfig3 on a server that had already been configured with a working environment. Notice how I said ‘working’ because after completing the install of ISPConfig3 this is where things got rather complicated rather quickly! I’ve not had much experience with ISPConfig but I was keen to see how it works and to see if it would make setting up email & web services. Well after 2 actual rebuilds I believe that I’ve managed to achieve what I set out for.

After the ‘First’ install (ISPConfig) It totally broke the server! All Web address resulted in 500 errors! Postfix was complaining about SASL Authentication I knew that I was either going to spend a lot of time trying to sort out the mess or just cheat and start a fresh. So after about 10 seconds, I said to myself…  “SCREW THIS” let’s just backup what I need and start fresh (something that is clearly stated for ISPConfig!)

Skip forward to mid morning, and things were going well until I enabled squeeze backports, then ran a system update thinking that gives me the advantage of updated software that’s not included with Debian Stable. Oh boy what a “HUGE” mistake that was! My fresh install was now pretty much in the same condition as it was when I broke it!

So again, do I even attempt to work out just how things went so horribly wrong? Oh no screw that! Enter rebuild #2. So one would expect by now that I should have a slight better idea on what/whatnot to do! Yeah OK I’m learning! but in all fairness this server is all about learning. I’m not qualified in this field of work, for me it’s just a hobby.

So there’s going to be broken links until I restore some content (wiki, statusnet, forum) as I’ll be working on that in the coming days… 🙂

Jetpack & Social Networking

I’ve most likely missed when this was implemented, but I just happened to notice a listing under plugins settings called “Social” this has listings for Facebook, Twitter, Tumblr,Yahoo & LinkedIn.

So the purpose of this post is to test the links for Facebook, Tumblr & LinkedIn as I already use WordTwit Pro for posting to Twitter. I gave up on using Facebook plugins because every time Facebook altered their API it always broke 3rd party plugins. The other issue is the free top level DynDNS domain name I’m using was blacklisted some time back so I can’t even post messages that includes the domain as it warns you that the domain is responsible for abuse so it’s banned .

So I’m interested to see how the Jetpack add-on handles posting, whether it simply places the body of the post on to  my Facebook wall, or if it summarises and links back to the original post, because if it’s the latter then it’s not going to work for me as intended.

I don’t think there’s going to be a problem with Tumblr or LinkedIn as they don’t have such a restrictions…

Ok enough talk let’s see what happens! 😉

Eyesight Follow Up

As I mentioned in the last post how radiotherapy side effects has caused damage to the surface of my eyes. Well today I had a follow up to see how the regular use of a lubrication ointment has (hopefully) helped in allowing the eye surface to repair.

Well today It was suggested that I should try using contact lenses over the glasses I got a few months back. This will have a dual benefit by correcting my short sightedness and to provide a protective barrier to the surface of the eye. 

I’ve been supplied with five days of disposable lenses to see if the contacts don’t irritate the eyes or introduce an infection. Well the first six hours were total bliss! The feeling when blinking felt silky smooth as opposed to gritty and dry.

I’m hoping that this allows my eyes to heal or at least settle to the point where they don’t deteriorate any further. So this is still a work in progress.
