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. 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. |

I am trying to post Part 3 of the Lab scenario. The spam-bot on the site will not allow me do it. So I attach it as a word doc. So anyone who wants it can download it and use.

yemi 22: I'm sorry. I should have done a round up of SDM. I will do something when I find a few minutes. About your routing problem, could post the config you have on both routers? It will give a clearer picture of where to troubleshoot. |
| Re: CISCO Thread: CISCO Professionals Identify Yourselves by sayso: 7:46am On Feb 22, 2010 |
@yemi 22,type show run and post what you have in your running config,from their the experts will see what went wrong. |

Hi guys. I think i've found my home in this thread. Let me know if you need any help on networking how-tos, or more specific things like ios, protocols, acl,etc. I prefer hands-on learning to cramming dumps and only knowing it on paper. Thanks to you nateevs for starting this, |
| Re: CISCO Thread: CISCO Professionals Identify Yourselves by sayso: 11:13am On Mar 01, 2010 |
@yemi 22,I will check through ur config,but for now try inputing clocking between the two routers. |
| Re: CISCO Thread: CISCO Professionals Identify Yourselves by yemi221(m): 3:55pm On Mar 03, 2010 |
@ sayso.tnx i was able 2 connect it.it was due 2 d clocking. |

Hello People, Please can someone tell me where all the ladies are? Come on girls, networking is fun. @Yemi, clocking was what caused it. @nateevs, so u finally appeared. @Whitehorse, its nice to have you onboard. @na2day, please go easy on that mail server dude. |

hello cisco proffs, e don tay i come here. anyway am new to VPN and i need serious help. I have been commissioned to set up an intranet and vpn for aclient with 3 regional offices , to incorporate voip , file sharing , print sharing etc Current head office has 4 servers namely mail server , i file server , backup server and proxy server, the email server is linux 7.2, file sever windows 2000 server , backup server windows 2000 professional, and proxy server linux 7.2 , the other office has a proxy server on linux , and the other no server but a cisco router , also the hq has a cisco router and asmi 51 modem for lease line for the proxy server and the mail server is connected via another isp through cable , all in all there are 2 isp serving the client 1 for email and internet and another for wan connectivity. Now the main requirement is to set the wan in search a way that everybody gets his mail from centralised mail server , can share files and also the phone system can be integraded to use VOIP. Please advice as i have to give the cost , hardware upgrade requirements, than set the vpn , and the intranet , the client user leve in total is 110 users. Any support would be well appreciated. |

yemi 22 what server do u intend to build and what are u going to be using the server for?? to eliminate the stress of actually building yurs, i suggest that u go oem on this one, brand names like hp, cisco comes to mind, this is on the hardware front, you also need to make sure that the hard drives in the server are in Raid settings 0 and 1 respectively, 0 setting meaning faster read times and 1 setting meaning data integrity. i could go on and on. just be ready to spend money, |
| Re: CISCO Thread: CISCO Professionals Identify Yourselves by nateevs(m): 6:37pm On Jun 06, 2010 |
I don't think he is asking for the server side of things. I think he is trying to set-up a WAN with centralized management and access of resources across 3 regional offices. 110 Users will be quite demanding. Think about having a cyber cafe with 110 pcs and all of them sending and receiving traffic all at the same time. Things can get pretty ugly in time. Add VOIP to that and if you have not carefully planned it, you could be looking like you don't know anything when you are done. Therefore the first thing you should consider is how much bandwidth you think is going to be consumed at peak periods. And remember well, total bandwidth must not exceed 75% of bandwidth available. And remember it's your upload speed that matters. Not download. And never forget . . QOS is your friend here. You then need to establish what technology is being implemented on the WAN. (Frame-relay, MPLS) Are the 3 regional offices connected on the WAN? Are they on common ISP? If two of the offices do not have WAN connections, the only way is to connect all three sites over the internet using VPN. My favourite is gre over ipsec. Also seeing that you have three sites, you are looking at a hub and spoke set-up. Are your branch offices offered static IP addresses or Dynamic addresses? With static you can peer all sites statically . . . With dynamic, you want to research into DMVPNs. The technology you choose to implement across is what will determine what kind of devices you use. (Also the cash the client has available - These things are not cheap). Cisco ISRs is what you need at your branch offices regardless of technology deployed. So many things to consider. These are what I can bring out form the top of my head now. Let's take it from here. . . |

This is really a nice thread. we need forums like this to help one another. am thru with CCNA and will be taking a module of the CCNP soon but guys networking is not all about cisco alone. i would love to know if anyone has tried MIKROTIK technology also, cos where i work we use mikrotik and i discover it is easier and better to work with than cisco. |

That's why I named the thread "Cisco Thread" . . We can't possibly cover everything networking in one thread. It'll be a big mess. I could agree that the devices you use are easier and cheaper to deploy than Cisco . . . but I cannot agree they are better. Until you tell how many Cisco products you've deployed and managed in a production network, you can't use the phrase "better than Cisco" . . . We have Juniper, Novell as big players and competitors to Cisco in Networking and an array of others. I personally deploy Wireless Technology for clients using Colubris Equipment across the board but only because it's cheaper. Every vendor claims to be easier and better than Cisco. . . the truth is Cisco do things well. When you want to deploy "Unified Communications". . . Cisco is the way. |

I am a newcomer in the field of networking.My desire to become a CISCO expert made me go out in search of a CISCO academy(meridian technologies=APTECH) and I was lucky to find one close to where I live.The training is expected to last for four months.I am a little bit confused,I am not sure if four months is enough to really tutor me on all the topic areas of CCNA(640-802).I would like to get your expert opinion on this issue.Thanks |
