An 101 question about whireshark:
I first flushed my DNS and then started capturing my interface with wireshark.
Then I opened google chrome and searched for a webpage.
Finally, wireshark except the first query about the url makes some additional queries for related names/urls.
for example :
Searched for www.aueb.gr and dns makes an additional query for art.aub.gr.
Why is this happening?
Thank you in advance.

Try using console application for DNS resolution (for example nslookup) during wireshark capture, it should give you exactly what you want. Web browsers or other applications can try to resolve some additional DNS entries, which may be the cause of the issue you are seeing.
For example:
nslookup www.aueb.gr
As for the behavior of chrome, web browsers will try to fetch additional resources (like images, cascading style sheets, scripts) in order to be able to display the web page correctly. If it happens that the resource is hosted in some other domain (like art.aueb.gr), the web browser will have to first resolve that domain name - and that is why you see additional DNS queries.

I am searching for a specific keyword in google and from different computers I am getting different results. On one computer, the website I was expecting for is the 3rd on the first page and on other computer, the website is not listed at all in the first page.
Is there some cache that I need to clear in order to have the search returning unique results on all computers?
Google's Personalized Search feature uses search history to personalize your search results. Since all searches on Google Search are associated with a browser cookie record, previous search results and visited websites can be used to provide more relevant results.
See "Step 3" of Google's Search and Browse Privately support page to turn off result customization.
If I am correct, your problem could be in the URL itself. This totally depends on the OS. (this is assuming you search is "keywords" and your OS is Ubuntu -->)If the OS'es are different, then it should be the client part in "https://www.google.com/search?q=keywords&client=ubuntu" (there are more parts to the url, but that's all i need to explain it. Just try taking out the client part from the URL.

I resigstered a new domain visitsoonvalley.com but now I can see that there is a sub-domain support.visitsoonvalley.com which I didn't create and I can't find in the cpanel too. This page is showing ads and the first advertisement is of the company that I registered my domain with. Is it possible that they created this sub domain? Are they allowed to do this without notifying me?
UPDATE: I just checked going to help.visitsoonvalley.com and same result. Why are these sub domains existing?!
You cannot register subdomains. You cannot really create them. You can only use them.
Most likely there is a "wildcard DNS resolution" for your domain. That would be something your provider has done and it actually does make some sense, since most people want that. Why don't you simply ask them? They will probably remove it from your DNS settings if you ask them.
A "wildcard DNS resolution" means that all DNS resolution requests to hostnames within your domain are resolved to the same IP address, without any specific rule existing. So it is a kind of "fallback".
Why there are ads shown in your page is nothing we can say. Might be some default content your provider puts in as a placeholder until you create content. Or they simply created a DNS resolution as a palceholder until you name an IP address the domain should be resolved to. Again: why don't you ask your provider? You pay them for their service, so usually that means the have to give support...
Certainly that is not exactly a "nice" behavior if that really is not mentioned anywhere in their policy. But on the other hand it does no harm and is only temporary...

I am trying to make an exception for a site to access my microphone and camera:
chrome://settings/contentExceptions#media-stream is not editable, is it normal?
How do I add a rule?
It's not possible as you would expect. Reported as a bug here and closed as Status: WontFix. Details below.
#14 freshst...#renuval.com Version: Version 28.0.1500.95 m OS: Windows 7 64 bit
We've read on an earlier Issue from 2011 that it's intended behavior
as well, but some people on the same Issue weren't sure:
https://code.google.com/p/chromium/issues/detail?id=71179
Chrome Help sites discuss the topic here:
https://support.google.com/chrome/answer/2693767?hl=en
Note that the Media Exceptions page doesn't explicitly say that you
can add exceptions, it only says you can deny. It does, however, point
you to the Manage Exceptions page on this topic which does say that
you can add using a button. This looks like it's just unintentionally
misleading.
After re-reading everything carefully, we assumed based on the help
article that the only way to de facto allow an exception is to click
"Allow" on a site requesting an exception that is running on HTTPS
as Chrome will only remember your preference for Media Exceptions on
HTTPS sites. It seems a bit restrictive for users who are savvy enough
to edit their own security settings deep down in the menu tree, but
security is security.
#15 ser...#chromium.org
Thank you freshstart. This is exactly it. Https
means that "allow" can stick.
Your question was also already answered on SuperĀ User:
You add a rule by going to the site in question and then, if Media
setting is "Ask when a site wants to use a plug-in to access your
computer", it should prompt you for what to do - that will then get
set as a specific exception.
You only use Manage Exceptions to remove existing exceptions.

Allow sites to access your camera and microphone and Manage
exceptions

A novice here. The support from mediaTemple and my current host have been quite unhelpful, so stackOverflow may be my hero.
My problem is that entering "www" before the domain and leaving it out direct to different servers.
The background on this is that I first registered the domain with mediaTemple and had a plan with their gridHosting, but after finding their service unsatisfactory, I cancelled my gridhosting plan and moved to another host. This problem occurs even after updating the nameservers. In short, the web server is hosted by proMinecraftHost, but the domain is registered under mediaTemple.
Support from both sides say it's due to dns and the nameservers needing 24-48 hours to update, but I'm fairly skeptical that it really is the cause.
Summarizing, www.mscraft.org directs to the correct server, but mscraft.org(mscraft.org) alone does not.
If anyone could help me, I'd greatly appreciate it.
Thanks in advance.
It's possible you just have the old DNS info in your cache. Try clearing your browser's cache, and also flushing your DNS. On Windows you could do ipconfig /flushdns in a command prompt. Also you could try pinging both addresses (with and without www). You should see the same IP address for both, as I got 198.154.108.107 when I tried them. In other words, I think it's working properly - you are just going to the old location because your machine is remembering too much.

Port 80 is forwarded to a server on my network which has links to the different projects I'm working on, how could I allow people to connect to the server running on my laptop when I'm using it? I would obviously not prefer to change my router settings frequently to port forward to my laptop. I want the user to access my domain and maybe have a set of links which will be described as static and another set which will have a description cautioning the user that said links will only work when I am online and they would somehow redirect to my laptop. (Lamp Server)
Well, if I understood correctly your question, you should configure your laptop as a reverse proxy for your main server.
As you said, you should have a set of links which will redirect to your laptop (via reverse proxy config), but of course these links will work only when your laptop is available.
