Panic at Cisco: The Misadventures of a 90s Network Tech

Introduction
In the wild and wacky world of tech, Mondays are not just regular days—they're the prime time for back-to-back blunders and learning opportunities! Welcome to this week’s edition of “Who, Me?”—a delightful dive into the hilarious mishaps of techies who aimed to troubleshoot but ended up sparking chaos.
Meet Sherlock
Meet our protagonist, a network tech we’ll call “Sherlock.” Back in the 1990s, Sherlock juggled multiple responsibilities as an IT manager at a company with several regional hubs, all meticulously connected to a central HQ via a 128K link. Smaller offices? They were tethered via 64K connections. Technology enthusiasts will recall how operational it was back then, yet how precarious too!
The Disaster
In the midst of these operations, Sherlock relied heavily on Cisco's IOS command line, famous for its autocomplete feature. With just a few keystrokes and a tap of the TAB key, he could quickly complete commands, thus saving precious seconds in a busy workday. But one fateful day, while attempting to pull settings from a remote box with a command starting with "net sh ip xxx", disaster struck. The seemingly harmless command caused his network connection to vanish into thin air.
Shocking Discovery
In a shocking twist of fate, Sherlock discovered that in that ancient version of IOS, “sh” stood for “shut” rather than “show.” The confusion stemmed from the inconsistent command shortcuts available; in his endeavor to gather data, he inadvertently severed the connection! Panic swept over him as attempts to re-establish the link failed—he had effectively shut down access to an essential node in the business network.
Scrambling for Solutions
Once the gravity of his blunder set in, Sherlock scrambled through the Cisco manual only to find little solace. His golden ticket back to sanity? A good ol' modem! Utilizing it, he managed to dial back into the remote office. But alas, his struggles weren’t over just yet, as he still needed to reopen the passage to HQ.
The Revelation
With renewed determination but dwindling options, he tried yet another command—“net open ip xxx.” To his dismay, it didn’t work! Confounded, he sought guidance from his engineer friend “Watson”, who provided a much-needed revelation. Watson asked the pivotal question: “Have you un-shut the network connection?” A light bulb moment illuminated Sherlock's bewildered state—he realized he had to use the command “net no sh ip xxx” to reverse his fatal error and reestablish the connection.
Conclusion
Once he got the command right, the network came back online, and Sherlock endured a trial by fire that would never be forgotten. The incident serves as a critical lesson for IT professionals everywhere: understanding the nuances of software commands can be the difference between seamless operations and catastrophic failures.
So, fellow tech enthusiasts, next time you’re delving into the depths of network protocols or confronting catastrophic command line misadventures, remember Sherlock’s tale! And as always, stay connected—whether through a 128K link or a fiber-optic connection, your network’s lifeblood is in your hands!
