Eletelephony

Once there was an elephant,
Who tried to use the telephant—
No! No! I mean an elephone
Who tried to use the telephone—
(Dear me! I am not certain quite
That even now I’ve got it right.)
Howe’er it was, he got his trunk
Entangled in the telephunk;
The more he tried to get it free,
The louder buzzed the telephee—
(I fear I’d better drop the song
Of elephop and telephong!)

Connect to the Internet via a Network Bridge [Windows]

You’ve got 2 computers at your place. A nice laptop, and a desktop that’s deprived of a wireless adapter. The laptop connects to the internet through the router, to which it wirelessly connects, however the PC has to do without internet since the router’s a bit too far away from the computer for a wired connection. 
In such a case, you might wanna consider (or might already have unknowingly) going for a network bridge. The idea is that you connect your computer to the laptop via an ethernet cable,  and the laptop to the router (WiFi). So in simple terms, you are connecting to the internet through the laptop which is connected to the internet.
But it’s not as simple as simply plugging in a cable. Some configurations have to be made, so here’s what you can do:
Open the “Network and Sharing Center” on your Laptop, and click on the “Change Adapter Settings” link. Select/Highlight both the Wireless and the Ethernet adapter, right-click, and click on “Bridge Connections.”
Now sit back and relax while Windows sets up the bridge and once done, check if another icon appeared among the adapters, representing the “Bridge.” Also, you might wanna check if both the two adapters are part of the Bridge. It’s pretty simple and all you gotta do is see whether or not it says ‘bridged’  next to enabled on the adapters’ icons. If either of them doesnt, right-click and select “Add to Bridge.”
Before you proceed, on your laptop, fire up CMD, and type in “ipconfig /all”, Note down the values it returns for “IPv4 address”, “Default Gateway”, “Subnet Mask” and “DNS Server.”
Now the Client-side configuration. On the other computer, go to the Ethernet Adapter’s IPv4 properties; check “Use the Following IP address.” Fill in the ‘Subnet Mask’, ‘Default Gateway’, and ‘DNS Server’ fields with the values you previously copied after running the ipconfig command on your laptop. However, in the IP Address field, add 1 to the last three digits, so that e.g. 168 becomes 169. As for the ‘Alternate DNS Server’ field, add 1 to the last digit just like you did for the IP Address. That’s it; check “Validate Settings upon exit”, click “ok”,”ok”,”close.”  After a few seconds, the other computer would be connected to the internet.

 

How to Assign a Static IP to on Windows Computer

A Static IP differs from a Dynamic one in the sense that the latter changes with every router reset, while the former always stays the same.
To change your IP to a dynamic one, follow these steps:

  1. Fire up CMD, and type in “ipconfig /all”
  2. Note down the values it returns for “IPv4 address”, “Default Gateway”, “Subnet Mask” and “DNS Server.”
  3. Open Network and Sharing Center (quickest and simplest way is to right-click the network icon in the system-tray and clicking on the link therein.)
  4. In the sidebar on the left, click on the ‘change adapter settings’ link.
  5. Double-click on the icon of whatever adapter you are connecting to the internet through.
  6. A window would pop-up. Right in the centre of the box, would be a list of items that the connection makes use of. Look for “Internet Protocol Version 4(IPv4)” in the list; select it; click properties.
  7. Another box would pop-up, but this one’s the last in the row. Now this step is where you make the real changes, but before you change anything, check if the “Use the following IP address” radio button is already checked, and if it is, quit straight away since it’s already static. However if not, then do check it.
  8. At least three of the previously disabled input fields would now be enabled. Fill the fields with the details you copied from the results to the ipconfig command. The last bit of the IP Address is variable and you can give it any value you wish, however, copying the existing would do the trick too.

That’s it you are done.

 

Creating a Counter-Strike Server using Port Forwarding and the dedicated-server application

First off, to create a server, you need additional files. The main executable of them being the “hlds.exe”, and if this one’s present, we must assume that the other prerequisites are present too, (including swds.dll, which is like a patch that allows non-steam clients.) If not present, just search for them, and download them.
Creating a server on a machine is no big deal. All you have to do is run the HLDS, and fill in the slots with whatever you wish, (who am I to limit the max no. of players on your server?) and I assure you that the slot for Server Name can carry anything. However, in the “UDP Port” slot, type “27015” since it’s the preferred (actually most-widely-used) port for CS. The Server’s up the moment you click But the thing is that the server’s local. It’s accessible only on your PC and on other computers on the same network, but not globally accessible over the internet. So how do we make it global?
That’s what we forward the ports for. To do so, login to your router, by typing the router’s IP address into the browser. TP-LINK users may consider this a complete step-by-step guide, though of course this applies to all, however different ones have slightly different UIs.
Anyways, once logged in, goto Forwarding and then to Virtual Servers, and click on . A form should greet you. Now in the Service port slot, type “27015”, (if there’s an “internal port” slot, leave it blank.) The rest can be left to the defaults, however in the IP Address Slot, type in your computer’s ipv4 address, and it should be static (unless you are looking forward to having to go through the whole damn procedure again and again.)
After inputting the IP, save the changes and now you are good to go.
Now others can connect to your server by typing into their CS consoles:

connect xxx.xxx.xxx.xxx:27015

(Replace ‘xxx.xxx.xxx.xxx’ with your router’s global IP address. To find out the global IP, the quickest and easiest way is to visit whatsmyip.org.)
