If I make my own vpn using raspberry pi then can anyone track me?
I have made a vpn on raspberry pi using Pivpn so can someone or the Pivpn owner see my activity online?
The question is a bit confusing and we need more information to follow up.
A VPN works by sending all your data through an encrypted tunnel to another far away server.
However if your raspberry pi is at the same location you browse the internet from (such as your home) your ISP will still be able to detect the requests you are making as they will still be made from your IP address.
More detail on the question and who you are trying to stop tracking you would be useful.

so I know a little bit about writing Linux kernel device drivers. And I wrote a device driver for my game controller. The problem is, I want to integrate my device driver to ROS. How should I do that? I don't want to use the pre-existing packages for ROS. And I tried to look for the documentation but to no avail. So, Any help would be appreciated! Thank you!
ROS is a strongly-typed messaging system, that wraps the real math/code up, to provide a generic interface via topics and messages. Write your code, write a ROS node, call your code from the ROS node, and define the publishers/subscribers/interface you want other nodes to talk to you by.

on my raspberry, I installed "motion" (the one with daemon) for my Pi Camera. However, I set up the Motion with the port 8081. If I open it on the raspberry using localhost:8081 it works but unfortunately with a big delay/lag. Maybe if you find a solution to this would be awesome. But my main problem is that if I want to open the server on my Pc by entering 192.168.xxx.xx:8081, it won't open at all. Using the IP without the port it still works. Maybe you find a solution.
The lag you encounter on Raspberry pi is because that same raspberry is processing the video input, and now you want to add processing of showing you that stream, after all, it is raspberry, no big deal there.
The Motion config file (/etc/motion/motion.conf) haves a setting named "Stream_localhost" by default it is set to ON, make sure you change it to OFF.
If you have any other problems I believe this simple instruction will help you.

EDIT:
After quick google searching I found out that two more settings must be set to off also
webcam_localhost off
control_localhost off

I am beginner to Perl and I have to write a script which could change the IP address after every 1 hour.
I want to change it because I receive some data from a dongle from a website and that website has some time limit to receive that data, so currently we need to unplug that dongle and use another to
change IP address. (I mean I have to request DHCP for another IP.)
But currently I am asked to write a script using Perl. Could someone please help me how to do that?
It's too broad. Have a look at Net::IP module, read the documentation and you're good to go.

So there's a lot out there on configuring MySQL to be accessed through a remote computer via localnetwork. I'm trying to connect to it using a device that is NOT on the same network and can't figure out how to do that!
More specifically:
I have MySQL on a computer running Ubuntu 12.04 LTS at my home
I want to be able to communicate with the database using an iPhone app (I know how to do the sqlite stuff on iPhone, but I don't know is how to connect to the DB from let's say the other side of the city/configure the database to support this)
I figure if I can connect to it using another computer not on the network that I'll be able to create a JSON-based service to gather the data, I don't require the iPhone code specifically
I'm assuming I need to set up some username/configure the IP for remote access on the server, but I'm quite the noob when it comes to that. Any help would be greatly appreciated! :)
May want to create an intermediate layer that handles the connection to the database, it can be useful a web service to connect to MySQL, and from the iPhone you connect to WS.

I am trying to learn about VPN using OSX and have a question I cannot find the answer to. Any help will be appreciated.
I have an office machine running OSX server 10.7. I set up VPN on it today and set up my laptop (running OSX 10.8) to access it. I am able to connect, but have a problem accessing a machine by its IP address on the office network. I suspect I have and issue because both my networks use the block 10.0.1.xx. Before I change one of my networks IP range I wanted to ask if this is the actual problem or if there is an easier way to resolve this. How would my laptop know that 10.0.1.127 is on the office network and it needs to look over the VPN connection?
Thanks for any help. Trying to wrap my brain around this whole VPN thing.

You are correct, having both address blocks set to the same address space is very confusing for your workstation. The actual problem is more gateway related, as your machine now has two gateways with (likely) the same IP address.
There is no good way to get that to work using the same IP range on both the local and remote networks.
Note that I said "Good way" I'm certain it's possible, just more trouble than it's worth.
