On My CCIE Lab Exam in 2001 — Day One

When I passed my CCIE in 2001, I remem­ber both the jubil­a­tion and exhaus­tion of the moment. Also the loneli­ness, after all, my wife and chil­dren had been without a func­tional part­ner and father for more than year, and they were not there with me at the final moment.

Let me explain.

IOS: ROMMON on the C6500/​Sup720 — Lesson Learned

Recently, one of my Supervisor 720 goes into a per­man­ent reboot cycle. I was able to break it into ROMMON mode, but I couldn’t get it to ‘stick’ the boot set­tings.
Finally.…

IOS: Reverse SSH Console Access — Part 2

Following my ori­ginal post about con­fig­ur­ing Reverse SSH on a Cisco con­sole server, I wanted to make some fol­lowup to extend the usage.

Rant: That Is Not an Apology CertGuard. You Have to Say Sorry!

So after Bred Reese got on the phone to Robert Williams at Certguard and told them what to do, they have con­tac­ted Ethan Banks. Ethan has returned to the web and indic­ates that all is well.
I am not so forgiving.

Rant: Who Is Robert Williams and Certguard ? And Are They Moral or Just Plain Stupid ?

I won’t go into the cir­cum­stances sur­round­ing CertGuard accus­ing Ethan Banks of cheat­ing. You can read art­icles at other Cisco Blogs. Here is my take:

What Is a CCIE ?

Originally pub­lished at Techtarget when I sent it to them for fun. Reproduced here because I wrote it, and it still seems funny today. Note it is deriv­at­ive from some joke that was around at the time.

Interestingly, much of the puns on CCIE study top­ics are for­got­ten tech­no­logy as mod­ern CCIE’s no longer study Token Ring, DLSW, Appletalk […]

Musing: On Reading and Learning From a Computer Screen

One of the other tricks I have had to learn is how to read from a com­puter screen. Here are my mus­ings on learn­ing and read­ing from a com­puter screen instead of paper.

Configuring Windows 2003 /​ XP SP2 to Use IOS NTP Server

In cer­tain net­works, it is dif­fi­cult to get the time on your serv­ers to be exactly the same as the NTP time on your net­work equip­ment. In this case, you want to force the Windows serv­ers to use the same NTP Network time source as your routers and switches. But Microsoft Windows doesn’t under­stand NTP […]

Fast Introduction to SOCKS Proxy

Introduction
In the Blue Coat for­ums I often see people ask ques­tions about SOCKS that show they haven’t taken the time to learn what it is. This is a fast intro­duc­tion to what SOCKS is.

Network Dictionary — Grok

In net­work­ing, used to describe your exal­ted under­stand­ing of a par­tic­u­lar net­work , typ­ic­ally by work­ing on it for enough time to know all the areas of the net­work includ­ing mem­or­ising IP addresses, archi­tec­ture, con­nectiv­ity. As in, I grok my net­work.
Also used in ref­er­ence to your exper­i­ence of a tech­no­logy, i.e. I know mul­tic­ast but I don’t grok it.

IOS:Open Source Lab DNS and IP Addressing

A num­ber of Cisco Bloggers have talked about mak­ing labs avail­able for oth­ers to use. However, part of what will be needed is some con­ven­tions to make these labs work for the largest num­ber of people.
Following Ivan Pepelnjak post­ing on Private Domain Names, and an earlier post­ing that I made on Reserved IP Address […]
