Securing Openvpn Access Server; frontend

Hiding the openvpn-as web interface from the internet was a logical step for security. This is a quick guide about securing openvpn-as webpages in Ubuntu if you tend to use the front-end infrequently.

In Terminal, navigate to your installed openvpn-as directory:
(might be different, depending on how it was installed)

cd /usr/local/openvpn_as/etc

Next we need to edit the as.conf file…. I recommend making a backup just in case! Continue reading “Securing Openvpn Access Server; frontend”

HDD benchmarks

Interested how a SATAII compared with a new SATAIII drive, I decided to do a quick benchmark to compare the results.
In this benchmark I will be comparing the Kingston HyperX 120GB SSD (S-ATA III), Seagate ST3320613AS 320GB 7200-rpm 16mb cache (S-ATA II) and a Western Digital Blue 2TB 5400-rpm 64mb cache (S-ATA III).

I am primarily doing this to compare the transfer rates of a faster, low cache S-ATA II mechanical drive with a slower, high cache S-ATA III mechanical drive. The reason, I hear you ask?
S-ATA III bus speed is rated at 6gbs compared with 3gb/s on the older S-ATA II interface.
A mechanical drive will never use up the whole bus width of S-ATA because of the way they operate, (all down to spindle speed and head speed) so my theory is that the faster the drive, the better I/O you will ultimately receive thus faster write and read speeds.

I used ATTO Disk Benchmark for the benchmarks and Piriform Speccy for the datasheets.

Looking at the results, I was quite surprised. To see a slower speed drive out perform a faster drive was not what I expected to see. As you can see, the HDD’s do not even fill half the bandwidth of S-ATA II bus speed, whilst the SSD is 100mb/s shy of hitting the top end S-ATA III speeds.

There could be a number of factors at play here; looking more closely at the Seagate’s spec sheets, it has endured alot of uptime and probably more spin-up’s then the WD will ever have. Also the test isn’t quite as scientific as having 2 “identical”  drives with varying speeds and that’s probably where you will see results.

On the back of this, I’m quite impressed to have had the Seagate lasting this long; the internet is littered with bad omens of Seagate’s from years of old! It might be time to replace this one whilst I’m still winning!

Playstation 4 HDD Upgrade

After much umm-ing and aar-ing about upgrading the PS4 hard-drive, the monumental amount of data I just delete to play something new has tipped the balance.
I’m quite annoyed with the situation to be honest, when the PS4 was released, surely someone at Sony could have worked out the average amount of games someone would play in 3 years, and then decide if the 500gb hard-drive is enough for not only the game files, but also the videos, screenshots and saved game data too.

This obviously wasn’t decided in spite, but they kind of expect users to sell the 500gb PS4 to then fork out more for the 1TB model. Seriously? They obviously aren’t a fan at people upgrading the hard-drive on their own as they don’t sell “official” upgrade packages for user installed HDD’s!

I kind of feel sorry for those “casual” gamers who know nothing about the relationship of the components and literally purchase a new PS4 for more space.
Anyway, I’ve purchased a 2TB Samsung ST2000LM003 hard-disk to install into my PS4 from Scan.co.uk. The capacity may be a bit overkill right now, but in a few years time, I might be pretty thankful for that decision!

BSKYB and your new TV

If you have been treated to a new TV during Christmas or have snapped yourself a great deal during the sales, you may find your Sky remote no longer controls some TV functionality after carefully setting up your new toy. Maybe your Sky remote has never worked with your TV volume and you constantly have to have both remotes at hand; this link may save your sanity.

The Sky remote is programmable to some of your TV functions, and can be reprogrammed if the current setup doesn’t work. This link from Sky should get you up and running again.

An example of some functions to use, for example, on a Samsung TV, selecting the TV button on the Sky remote and pressing i will bring the input selection up on screen. Pressing TV and help will bring up the TV’s inbuilt settings. Different buttons will interact differently depending on the TV you have, so enjoy playing around!

EDIT : I had trouble finding the revision code; its located inside the battery cover. Other models may be located at the same area.

The highlighted text has “rev.9f” This is a rev.9 remote.
