DEFAULT ROUTİNG

Default routing is used to send packets to the next-hop router for an unknown remote destination network that is not in the routing table. Default routing should only be used in stub networks, which are the only way out of the network.

As you can see in the above picture, while R1 and R3 can be used defective routing. Because R2 is not effective to use the default routing.
Router(config) #ip route 0.0.0.0 0.0.0.0 10.0.0.1
The above command means to send all unknown packets to output 10.0.0.1, wherever they come from.

Suppose we accidentally delete our files on the cloud system you use, Enterprise and Personal OneDrive. So can we get our files back again? Our answer will, of course, be yes, below we will explain step by step how to recover your files or restore the system if an error occurs in the OneDrive system.

Now, when we first enter our Hotmail(Outlook) account, click on the dots in the upper left corner.
We click to go to the OneDrive system.

Networking in VMware Workstation was the same as before, with the versions. You can create a LAN connection and run multiple virtual machines on VMware Workstation and work on the same network with these machines. We will see step by step how to create a network in VMware Workstation 8.

Now Let’s See How to Create a LAN Connection in VMware Workstation

After creating and managing folders of our virtual machines, click one of the virtual machines we created in the Library pane. Settings and detail information of the machine, properties are shown in the window of the VMware interface as in the picture below,

SQL injection is a web security vulnerability that replaces the OWASP (Open Web Application Security Project) Top 10 every year. In shortly, SQL injection is caused by the fact that the data from the user is directly included in the SQL query.

In the example below, there is a simple login page written in asp language.

         FUsername = Request.Form("username")
         FPassword = Request.Form("password")

               Set RsLogin = SQLConn.Execute("SELECT * FROM Members WHERE username =      '" & FUsername & "' AND Password = '" & FPassword & "'")

         If RsLogin.EOF AND RsLogin.BOF Then
                Response.Redirect "/error.asp"

         Else
               Session("login") = RsLogin("user_id")
             Response.Redirect "../"

         End If

Let’s examine this code.

IP ROUTING

Routers know how to reach the networks they are connected to. However, they do not know how to reach remote networks that not connected. But, they can learn how to access remote networks to which they are not connected by using one of the following routing protocols.
1. Static routing
2. Default routing
3. Dynamic routing
a) RIP (international standard)
1) RIPv1       2) RIPv2
b) IGRP (cisco-based protocol, but not supported by cisco anymore)
c) EIGRP (cisco-based)
d) OSPF (international standard)
e) Is-Is  (international standard)
