EMA finds that the rise of internet connectivity for next-gen WAN does not spell the death of MPLS.
Check out this selection of tunes tailored for those who work to keep the network up and running.
I was reading Ivan’s blog as I often do when I came across this post about why certifications suck.
The author Robert Graham had a sample question from the GIAC Penetration Tester (GPEN) exam. The question looked like this:
By default, which protocol do Linux systems use to transmit packets for tracing a network path? a) UDP b) TCP c) ICMP d) TTL e) ECHO
Obviously being a networking expert I have my networking glasses on but I have to respectfully disagree with these gentlemen that I don’t think this is such a bad question at all. Trust me, I’ve seen much worse.
So traceroute works differently on different operating systems. If you work with penetration testing I would argue that you need to have a good understanding of different operating systems. You should know how they behave, what their characteristics are and how you can fingerprint them. The correct answer here is UDP. Linux systems and Cisco devices normally use UDP to send packets for a traceroute while Windows systems use ICMP when doing a traceroute. The answer is of course not TCP because TCP would require the three-way handshake and why would a device want to start a Continue reading
I was fortunate enough to be given a chance to test the new virtual QFX 10k image from Juniper. In this post I will show how to import this image into UnetLab and demonstrate the basic L2 and L3 EVPN services.

Do you need VRFs?
Read the previous blog post. If the answer is NO, you can stop reading. Otherwise, carry on.
