NetGUI, a practical example Connect 2 routers
Hello!
been a while since I talked about NetGUI , free network simulator in the style of Packet Tracer, but machines designed to work with GNU / Linux. Today we will see how we can use, for example, illustrate the operation of NAT and its configuration on a Debian machine.
The scenario with which we work is as follows:
We have a local network with two computers (PC1 and PC2) on the 192.168.1.0/24 network connected to the Internet through the gateway router. This router is connected to the ISP's router (network 80.0.0.0) and the Internet is represented by 2 web server host (network 90.0.0.0).
The following images show how they have configured the network interfaces and routing tables for each machine:
If you now try to ping from local network to any Internet machine, it is clear that we will not do, because We have a private address and our gateway is not doing NAT. The machines outside the local network will not know how to answer our requests for echo.
Let configures your router to do NAT gateway so that all traffic sent to eth1 interface will be modified by replacing the source IP of each datagram by public IP (80.0.0.2):
If we return to make the machines ping the Internet from our local network, we see that now come without problems:
If we check IPTables counters, see how effectively the rule that we created is being used properly:
NetGUI is a very interesting tool that allows you to create complex scenarios to test different configurations, so I recommend you to take a look.
Greetings!

Cisco - Serial Interfaces
Hola!
to connect 2 Cisco routers via their serial interfaces, it can use a null serial cable connecting a DCE to a DTE.
By default, Cisco routers are DTEs (Data Terminal Equipment). This can be a problem when connecting 2 routers directly, because one of the two has to act as DCE (Data Circuit-Terminating Equipment) in this connection.
The DCE must send the clock rate to the DTE, so you have to configure it. Cables DCE / DTE are physically stamped on the connector itself to identify the corresponding letters, but what happens if we can not see? We can use the command show:
That's it. Greetings!

The DCE must send the clock rate to the DTE, so you have to configure it. Cables DCE / DTE are physically stamped on the connector itself to identify the corresponding letters, but what happens if we can not see? We can use the command show:
R1 # show controller serial 1 HD
unit 1, idb =..., driver structure ...
buffer size 1524 HD unit 1, V.35 DTE cable
R2 # show controller serial 1 HD
unit 1, idb = ..., driver structure ...
buffer size 1524 HD unit 1, V.35 DCE cable
Once we know what the team must act as DCE clockrate configure it to have it sent to DTE:
R2 (config) # interface serial 1
R2 (config-if) # ip address ...
R2 (config-if) # clockrate
56000 R2 (config-if) # no shutdown
R2 (config-if) # exit
R2 (config) # exit
And set the DTE:
R1 (config) # interface serial 1
R1 (config-if) # ip address ...
R1 (config-if) # no shutdown
R1 (config-if) # exit
R (config) # exit
That's it. Greetings!

Open Mesh Project: how to fight an Internet blackout
Hello!
The other day I read an article Shervin Pishevard very interesting, Humans Are the routers, which tells how the Egyptian government to see that the Internet caused a blackout during the riots, came the idea of \u200b\u200bstarting a project that would allow people could follow communicating to organize their protests. So I tweeted the idea and literally within hours the project was born Project Open Mesh (based on the concept of mesh networks ).
Open Mesh networks for connecting various devices (computers and smartphones wlan card) to each other, and are very robust, with continuous connections that can be reconfigured and overcome fallen nodes or blocked, jumping from node to node until it reaches the destination, either another device or network node that connects to the Internet. When an Internet connection available to extend the number of people who can connect. When there is not, these networks allow people to continue to communicate if other forms of electronic communication are down or blocked.
is a very interesting project and very nice it is seeking to create community, so seeking volunteers to assist, in particular, experts in wireless card firmware, software developers and companies to develop WLAN equipment, both hardware and software.
Greetings!
