How to enable IPv6 on your Sophos UTM (Former Astaro Unified Threat Management)

Step 1: After logging in to the admin interface, go to Interfaces and Routing -> IPv6, and enable “IPv6 status”. As my UTM recieve a IPv6 prefix from my ISP, i end up with this: 1   Step 2: Assign an IPv6 address to your internal interface. This address should be the first IP in your assigned IPv6 prefix. To calculate your range, copy your delegated prefix and go to this calculator. Notice that i have used a /64-prefix internally. 2   Step 3: Go to Interfaces and Routing -> IPv6 -> Prefix Advertisement. Select your internal interface. Then add the IPv6 address of your DNS Server, or the IP of your internal interface of your UTM handes DNS itself. 3   And voila, your internal clients should now be able to recieve IPv6 addresses. I recommend rebooting both the UTM and any clients if they do not get any addresses at this point.


How to fix LockObtainFailedException on Solr start

If you have experienced a Solr crash during a commit (which, of course, is the worst possible time, Murphy`s law etc), you might have received a LockOptianFailedException when trying to start Solr. This makes it impossible to start Solr at all.

You can solve this by configuring Solr to delete any lock files when starting up,
you can also configure Solr to use a normal lock file instead, which you can manually delete if you prefer that.

Simply correct your solrconfig.xml to the following values, they are per default
commented out in solrconfig.xml.



How to measure the temperature of your Raspberry PI

When running Raspian on your PI (and other distro`s for PI), an Raspberry PI specific application is installed, which let you monitor everything from volt-status, HDMI-status to the PI`s core temperature.

To check the core temperature, simply run the command  “/opt/vc/bin/vcgencmd measure_temp”

PS: Run the commando  “/opt/vc/bin/vcgencmd commands” to see all the data you can extract via that application.

Unfortunately, it does not appear to be possible to check the temperature elsewhere on the (physical) Pi, without getting a temperature sensor.


Guide: How to make money in GTA V (GTA 5)

Here is a short list with five items explaining how to make money in GTA V / GTA 5.

1: Be a taxi driver!
Steal a taxi, then you can accept taxi jobs around in the game, if yo drive nicely, you will even get tips for the rides. You can earn upwards of $300 for a single ride.

2: Kill people and steal their money
You can rob people after killing them, the problem with that is that the police will get on your tail. Not very viable in the long-term… PS: If you hang around an ATM, then rob them those who withdraw cash, you are more likely to earn some more cash.

3: Go on the stock market
You can invest money in the stock market, it is not a guaranteed profit, so you should not do this unless you have money to lose.

4: Rob armored cars
If you see a blue dot on the map (unless when the cops are after you!), that means that there is an armored car there. If the car is parked and you see a person walking towards it with a suitcase, you can earn $5K by shooting him. You can also steal the car and break open the back doors.

5: Rob stores
Any store that is open for business, can be robbed! By walking into a store, then slowly going back, so that your character keeps the doors open (with the doors pointing outwards), you can equip a weapon. Shoot the cash register and they will open up and you will get your money!

How to install Raspian for Raspberry Pi from Windows

I am currently in the process of setting up a SETI@Home cluster running on Raspberry PI boxes. Currently i am working with three nodes, and i will expand it if is a success.

For OS, i use Raspian (Debian clone), combined with some cheap 8GB SDCards from a random cheap vendor.

In order to install the Raspian ISO image to a SD card, i use the application win32 disk imager, which simply takes a ISO image, and writes it to a designaded SD card.

It is worth noticing that this will cause the partition(s) on the SD card to not be any larger than the image itself. But you can fix this upon your first Raspberry PI boot, as the application “raspi-config” will be auto-started. (if not, start it)
