CCIE – CCIE SPv4 Review by Nick Russo
My friend Nick Russo just took the SPv4 lab and passed it. This is his story.
On 8 March 2016, I passed Cisco’s CCIE Service Provider version 4 lab exam. It was my second attempt. I realize there is little information on the Internet about this test because it is still rather new. This blog post will detail my personal strategy for passing the CCIE SPv4 lab exam. Most CCIEs and CCDEs agree that a smart strategy is a critical part of passing any Cisco expert-level lab; many folks are technically proficient but need to remain organized to be effective.
Note: the views expressed in this blog post are mine alone and do not necessarily represent the views of Cisco. No correlation between my comments and Cisco’s recommendation study strategies should be made. Also note that no technical exam content is discussed here in accordance with Cisco’s CCIE NDA. Comments fishing for such information will be deleted.
First, the new blueprint has 3 sections: Troubleshooting (TSHOOT), Diagnostic (DIAG), and Configuration (CONFIG). The CCIE SPv4 program explains these topics in detail within the new blueprint so that is not discussed again here. Since each section is slightly different, one should have Continue reading
Junos Space – checking processes are running
After two miserable nights trying to upgrade Space 13.1R1.6 to 14.1R1.9, I finally called up JTAC for some assistance. For some reason the upgrade started, but never finished – the GUI remaining in ‘maintenance mode’ for several hours.
What they did:
Checked the services – all were showing as down:
service jmp-watchdog status
service jboss status
service jboss-dc status
Tried to start jboss-dc, but it complained that it couldn’t write or create /var/log/jboss.
Did the following to change ownership from root:root on the /var/log directory:
chown jboss:root /var/log
Did this:
service jboss-dc start
service jboss start
At this point the GUI started showing ‘Junos space is preparing to start up’, and after 20 minutes it changed to say the applications were deploying.
PHPBB and website integration
I needed to integrate a website login with a phpBB3 forum recently, and this blog post came in really useful: http://www.3cc.org/blog/2010/03/integrating-your-existing-site-into-phpbb3/
The only issue with it was the logout section – it uses $_GET, but when I implement this I get a message saying that this is an ‘illegal use of $_GET’.
Instead, the logout code that worked for me was this – it uses request_var() instead:
<?php
$cp = request_var('cp', '');
if ($cp == "logout") {
$user->session_kill();
$user->session_begin();
echo "Logged out";
}
?>

Going to CiscoLive US 2016? Don’t Forget Your Kilt!
I don’t recall the exact details of how “#KiltedMonday” started last year at CiscoLive US 2015.
I just know
- Erik (@ucgod), Steve (@wifijanitor), and JD (@subnetwork) were pivotal to the wonderfully fantastic and fun idea
- I’m SO joining this year! — Just ordered my kilt.
- Scott (@ScottMorrisCCIE) is not only planning on joining this year… but he is hoping it falls on the day he will be presenting

Research ‘net: The TEMPEST edition
When I was in the US Air Force, as part of the 438th Communications Group, we had a Group Readiness Center that contained a large board with the airfield equipment status, a safe with various drawers with different classification levels, a couple of encrypted communication systems, and… a couple of strange looking Z200 computers. The screen on these computers were covered with a fine mesh, and the power cables ran through a special cleaning box. What was the point of all this fanciness?
TEMPEST. The ability to gather information about what’s on a computer’s screen by examining the signals transmitted (unintentionally) from the monitor screen, power cable, and other electronics. This might seem odd, but essentially any wire is an antenna that can (and will) carry information from a computer; at some range, these signals can be detected and deciphered in a way that allows you to determine what the computer is processing. Screens are more fruitful, as the older style Cathode Ray Tube (CRT) displays essentially shoot a stream of electrons onto a piece of glass, some of which must leak, and hence can be picked up and decoded to see what’s on the screen from quite a distance Continue reading
