Re: CISCO Thread: CISCO Professionals Identify Yourselves by Whitehorse: 10:43pm On Feb 12, 2010
Hi All,
I also stumbled across this thread; its rather interesting.

Well, i geuss i'll see how i can contribute, especially to the Cisco newbies. I'm CCNA,CCVP, CCSP, and work in the Oil industry in the UK. I'm presently (trying) to study for my SP CCIE. I worked in Nigeria till 2006 when i left the country, so i got most of my experience from there.

Like i said, i'll focus on the newbies, and over this weekend, i'll draw up a list of topics i'll post on, setting a foundation for deeper things. I'll post the topic list first, and you guys can let me know if its ok to proceed.

Neteevs,
Where you able to test your multicast scenerio? Below is a post i did about multicast on Sadikhov.com/forum

All,

For those that are interested, below is a simple way to test and/or learn more about how multicast works on Cisco routers.

Setup a test bed as illustrated (or something similar) in the pdf file in the zip file attached. My router configs are also included.

Now download the Windows Resource tool kits from the Microsoft link below (you can also get it from the Windows 2003 server CD).

http://www.microsoft.com/downloads/details.aspx?familyid=9d467a69-57ff-4ae7-96ee-b18c4790cffd&displaylang=en

Install the Resource tools kit on both laptops. Also turn off your windows firewall during the test. Remember to turn it back on after the test!

From command prompt on each laptop, go to the path you installed the Resource kit, for example
D:\program files\windows resource kits\tools.

Now run the mcast.exe, which is the multicast generator/receiver. I have also included sample batch files I created to send and run multicast for my test. You can change various parameters in Mcast.

PS: I conducted the test using dynamips, and used to loopback interfaces on my laptop to simulate having two laptops connected to the routers.


The sadikhov article can be found here http://www.sadikhov.com/forum/index.php?showtopic=167658&st=0&p=848275&fromsearch=1&#entry848275

Enjoy, and talk to you guys soon.

I wish you well in CCNA Exams. . .
You should ask when you don't understand some terms we use in here.
Those that know will give us some more info on what they are talking about.

yemi 22:

hi everyone need an explanation on SSH. and also is it compulsory to use SDM  in configuration.

With remote network access and management, the norm was to use telnet as a communication protocol. Telnet is insecure as it sends everything between the communicating devices in clear text. Someone with a packet sniffer in the middle of the communicating devices could sniff and see data being sent in clear text. Things like passwords This is insecure and very bad for data integrity and confidentiality.

SSH is the answer to that. It encrypts all data sent between the communicating devices. It provides data integrity and confidentiality. SSH usesTCP port 22 during communication.


SIMPLE LAB TEST.

Set up two Cisco routers connected via an ethernet switch and a pc on the network. So your setup looks like this:




Re: CISCO Thread: CISCO Professionals Identify Yourselves by nateevs(m): 11:50am On Feb 18, 2010
PT2.



If you don't have routers, download a program called GNS3. You will be able to simulate real live Cisco routers on the program.
Next step is to download WIRESHARK on your pc. Wireshark is a sniffing tool.

Now configure passwords on the vty lines on both routers.

Router#conf t
Router(config)#line vty 0 4
Router(config-line)#login
Router(config-line)#password cisco


Configure IP addresses on the Fast ethernet interfaces of both routers. Make sure the IP addresses are in the same IP subnet. You will also need to configure the LAN port of your pc in this same IP Subnet.


Launch Wireshark (You will need to set the properties of the network interface of the pc connected to the lab to "Promiscous mode" so you can see packets transfer in real time.).

Now from the PC, telnet into any of the routers. The router will prompt for a password. Enter the password you configured. When you are inside the router, qucikly take a look at the Wireshark program you should see telnet communication between your pc and the router you are telnet into.
Analyse the packet. You will see that the password you entered on the router is on there in clear text. This is the danger. Every other communication between the pc and the Router on the vty line is also sent in clear text. Anyone with a packet sniffer can sit on the network and see ever thing going on between the router and the pc.

Not good!

PART 2


If you do not have routers you can download GNS3 from the internet and install on your pc.
You are also going to need[b] WIRESHAR[/b]K. Wireshark is a network analyser - it is also a network packet sniffing tool. Download and install it.


Now configure both Ethernet interfaces of your Router with IP addresses within the same IP subnet. Your PC connected to this setup must also have an IP address in the same IP subnet.

Now configure the vty lines on your router.

Router#conf t
Router(config)#line vty 0 15
Router(config-line)#password cisco
Router(config-line)#login



Launch Wireshark. Set the network interface on the pc to "promiscuous mode" within Wireshark. This allows you to monitor packet transfer in the network.

From your pc, telnet into one of the routers. The router will prompt fro password. Enter password. Now quickly watch the activity on Wireshark. You should see TCP packets on port 23 from Source address (PC) to destination address (router). Click on it and then analyse the packet. You should see the password you typed into the router in Wireshark. Right there in plain text.

This is very bad. Someone with a packet sniffer like Wireshark can see your vty passwords, gain access to your router, modify or steal information your network.

We don't want that.
Re: CISCO Thread: CISCO Professionals Identify Yourselves by nateevs(m): 2:02pm On Feb 18, 2010
PT3.

Now clear the config on the router and configure SSH on it this way.
Remember to reconfigure the Ethernet Interfaces as well.



Router#conf t
Router(config)#username admin password cisco
Router(config)#ip domain-name nateevs.com
Router(config)#crypto key genrate key rsa


You should see this output on your router. . .

The name for the keys will be: R1.nateevs.com
Choose the size of the key modulus in the range of 360 to 2048 for your
General Purpose Keys. Choosing a key modulus greater than 512 may take
a few minutes.

How many bits in the modulus [512]: 512
% Generating 512 bit RSA keys, keys will be non-exportable, [OK]


*Mar 18 14:09:19.401: %SSH-5-ENABLED: SSH 1.99 has been enabled



It is also good practise to configure ssh authentication retries and time out on the router

Router(config)#ip ssh authentication retries 3
Router(config)#ip ssh timeout 60


Next is to configure the vyt lines to accept only SSH this way:


Router(config)#line vty 0 15
Router(config-line)#transport input ssh
Router(config-line)#login local



We are good to go. Now on your pc, try to telnet into the router again. This is what you should see.


C:\Documents and Settings\Nateevs>telnet 192.168.1.1
Connecting To 192.168.1.1, Could not open connection to the host, on port 23: Connection failed




The router no longer allows communication on TCP port 23 (Telnet). You can only now SSH into the router. To do that, you need to download and install an SSH client software like Putty or Tera term. Enter the IP address of the router. You will be prompted to authenticate. Enter username and password configured.

Launch Wireshark. Click on and analyse packet transfer from source to destination on TCP port. You should see this:

Launch Wireshark. Click on and analyse packet transfer from source to destination on TCP port. See attached doc. You should see that the packet is encrypted.

That's SSH in a nut shell. Read up on some more and it's straight forward.

If you have any problems executing any of the above tasks just post here.
