Part 2 “Intruder Alert!”

ospf2     We did a lot of work yesterday trying to fix the network. The Information Security Specialist at the county sheriff’s office informed us that the intruders got into the network by “TELNET”

 Unfortunately, our previous network engineer didn’t use SSH also known as (secure shell) and we have been open to the internet for some time! I guess it was only a matter of time until someone infiltrated us? As network engineers, make sure you LOCK IT DOWN with passwords, logins, and encryptions. Another way to help secure your networks are by using firewalls, ACL’s, restrict ports, and physical connections.

Lab – Configuring OSPF PART 1

INTRUDER ALERT

    Oh no! It seems as if some one has destroyed our network! Our previous Network Engineer wasn’t too experienced and forgot to set some passwords and secure the networks from intruders!

    Not only did they mess with our configurations they rearranged some of the wires! Now we don’t know what goes where! They also stole a hub and I believe they have my stapler!

    All is not lost, I found the field operations manual (FOM) and back up logs from our previous Network Engineer that kept diligent details of the Logical Topology and IP Address Schemes!!ospf

Static Routing & Trouble Shooting. {LAB}

Static routes are an easy way to connect a few nodes together!

How ever, it can become extremely tedious work if your network grows into a larger enterprise!

Wanna play?

Happy Valentines day!

 A couple of years ago , I got the best Valentines Day gift ever! Long story short, my husband paid a ransom for me.

Literally. He went to Western Union and wire transferred $500.00 dollars for my release.

To be a Network Engineer or not to be?

“All roads lead to Rome…” Routes,  infrastructures, hidden passages, tunnels……railroads.

   As I’ve mentioned before, I love Packet Tracer. I love playing with the commands and building new and interesting networks.

Routing & Switching, VLAN, EIGRP, IPv4, DHCP

Packet Tracer from CiscoVlanDhcpEigrpIpv4

I love Packet Tracer. 

You can be as creative as you like. You can purposefully destroy your creation and rebuild it, with a new or existing foundation. It’s like a never-ending puzzle, it can go on forever! 

It’s not to difficult to master, as long as you can memorize some coding and commands. Everything else is up to you, you choose how you want to connect. There are open and closed doors, locks and chains, clicks and  cliché’s! I’m not just talking about packet tracer any more either, I’m talking about computer networking and network engineering. 

Click Here  to download the Packet Tracer Topology/File on “Routing & Switching, VLAN, EIGRP, IPv4, DHCP”.  It’s fully configured and ready to go!

Can you Subnet?

subnetbinaryIf you’re like me, you can’t. Well I couldn’t anyways………I was a mess at it.

I tried everything, videos, forum after forum, blog after blog, nothing made sense.

No. I didn’t find some magical cure nor some special equation. It just took time, patience, and Advil.

Eventually I got it, it clicked. The light enumerated!

I’ll show you which sites worked for me and how I was able to master binary/subnetting.
