Troubleshooting HSRP
Q: I have two HSRP-enabled routers in Chicago and two HSRP-enabled routers in the neighboring suburb of Wood Dale connected by point-to-point T1 links. My problem is when the active line goes down, the standby does not automatically take over the role of active router. I have to manually change the priority on the standby [...]
Running EIGRP in PIX: What’s the Workaround?
Q: We have a network which connects to the ISP with an E-1 for Internet and, at the same time, connects to a satellite link (different ISP) which we use as a backup to the Internet.I want to install a PIX firewall (535) for this network and we are running EIGRP. Almost all reference materials [...]
IPv6: What’s the Rush?
Q: I saw a recent article about IP version 6 and how everybody needed to start changing their addresses over in order for the Internet to continue working. My boss started asking me questions about this, and I don’t know what kind of answer to give.
None of my friends seem to be concerned or interested [...]
LINUX CERTS AND THE CUTTING EDGE
I was struck by an odd observation this week. Desperately in need of shelf space, I began going through stacks of old books and tossing them or packing them away for storage.

To become certified, you’re required to do a number of things:

CODES OF CONDUCT
There seems to be a trend afoot to create or refine codes of ethics for all professions. CompTIA has one of the most succinct ethics policies that I’m aware of; instead of belaboring the point ad infinitum, the company takes a difficult topic and condenses it rather pithily: http://certification.comptia.org/resources/conduct_policy.aspx
Now, while CompTIA doesn’t publish numbers for [...]
NUMBERS DON’T LIE, BUT…
Many of you wrote to take issue with my recent discussion of vendor numbers: Cisco topped 1 million certifications granted since the beginning of its program, Microsoft is over 2 million, etc.
While I wholeheartedly agree that the numbers aren’t mutually exclusive — one individual may hold more than one Microsoft certification, or may hold a [...]
