GREs (Generic Routing protocol encapsulation) were submitted to IETF by Cisco, net-smiths, and other companies on September 10, 1994, marked as rfc1701 and rfc1702. Currently, most network devices support the GRE tunnel protocol.GRE specifies how to use one network protocol to encapsulate another network protocol. The GRE tunnel is defined by the source IP address and destination IP address at both ends. Yo

GRE (Generic Routing Encapsulation) Overview
GRE is one of the most traditional tunneling protocols, and its fundamental function is to realize the tunnel function, the two remote networks connected through the tunnel are like direct-attached, GRE, which simulates a direct link between two remote networks to achieve direct connectivity, and for this reason the
Credentials-see below.Then create an SMTP credential Click to create, and he automatically creates an IAM role and authorizes it, and produces a set of information similar to accesskey, but the name becomes username and password, like this:IAM User name,smtp username,smtp Password"Ses-smtp-user.xxxx", akixxx,aqbxxxxxxxxxxxxxxxxxx(3) This information is collected by using SMTP email. You can use Configobj to load credential in a configuration file and Smtplib to create an object to send messages

Anyone who has some knowledge about networking must know tunnel encapsulation technology. In the network, we use the GRE protocol to encapsulate data packets. So today we will have a basic understanding of this agreement. Next, let's look at the text.
1. Protocol Introduction
The GRE (generic routing encapsulation, universal routing encapsulation) protocol encapsulates the datagram of some network layer pro
The GRE protocol is used to build a channel that passes through the public Internet, so that non-IP traffic based on protocols that cannot publish routes can reach their destination.
To attack hosts on the internal network, you need to know the external IP addresses of the two terminals that provide the GRE tunnel and the internal IP addresses of the hosts you want to attack. This can be achieved through mu

The tunnel, literally, is a passageway, which is made up of point-to, stand-alone and other. The tunnels under Linux are not well understood, write down the recently built GRE tunnels and route forwarding functions.Let's talk about the basic concepts of tunnels:The interconnection of two or more subnets of a technology (protocol) or strategy through another technology (protocol) or policy, called overlay topology, is one of the timeless themes of tele
