Over the past few months I have been ramping up for the next phase of my career. I strongly believe that Data Center technologies are going to power the future of not only servers and applications but indeed all sectors of IT services including networking. Recent announcements from both Cisco and VMware about competing virtual firewalls, new L2 virtualization models within VMware and players such as Vyatta seem to indicate that I am correct. So along those lines I have been working to re-design my home lab and ramp up to learn these technologies as well as knock down my CCNP in prep for starting my CCIE early next year. Read more

Sometimes we just dont need routing
More than once lately I have come across L3 capable switches that have ip routing enabled by default even though it is not visible in the config. This has happened on every single 4500, 4900, 3560 and 3750 I have touched in the past 6 months. So I am pretty well aware that the first thing I need to do if the device is to function as a basic L2 switch is do no ip routing. However it appears that this is lost on quite a few people. I have been working at a client for a few weeks who is doing a basic core routed vlan network with dot1q trunks to each of their sites off of their Metro Ethernet WAN. The issue has nothing to to do with normal traffic but instead management traffic. If you have ip routing enabled and have also set ip default gateway your going to end up with some problems getting to the actual device to manage it. If you are not going to use a VRF for management simply do no ip routing on the device and it will work just like any other L2 only switch.
Do Not Social Engineer Yourself out of Clients or your Job!
About 9 months or so ago a weird thing happened to me. I had been using Twitter heavily and liked the idea behind 4Square. So I added the app to my BlackBerry and started checking in. Then as I prepared to meet a friend after work at his office I got a call from my then General Manger demanding to know where I was. Being after work I told him meeting a friend, but he persisted. So I told him. At that point he demanded to know why I was there and if I was on company business. This whole situation pissed me off but more to the point exposed that people are tracking us via our social media footprints with the right to do so being granted by our use of the systems. In this particular case it was me posting to 4Square, which injected a tweet into Twitter which was then re-posted into LinkedIn where my GM and I were linked and he was watching my activity.
Right then and there I pulled the 4square app off my phone and turned my Twitter geo-tagging to optional. My reason had nothing to do with being tracked by my management. All they have to do is ask and I tell. I don’t really care that some people have no real work to do, so they stalk employees via social media. As a matter of fact we should assume managers do this crap. The real reason was that I realized how easily I could expose information about clients Read more
“the books you read and the people you meet”
Ever since I saw Dave Ramsey at Catalyst a few years ago I have been a huge fan. Then last February we went through Financial Peace University. From that point on I have pretty much become a zealot. Yeah I’ll admit it. Since February we have led two more FPU classes and until our local talk radio show moved to a new format I listened to Dave everyday. As it is I continue to listen on the net and the podcast.
One of the lines that I have taken to heart is then Dave talks about one of his friends saying “your only difference between now and ten years from now will be the books you read and the people you meet”. I think there is something to this. For me I meet new people everyday and in the past two years I have been lucky enough to not only meet new people but actually interact with them and grow my sphere of friends and colleagues. One thing I have not been doing though was reading non-fiction outside of the technical material need to do my job. In January though I committed to changing that and if you will notice the sidebar of the the blog or choose to click on this link you see what I have, am and will be reading.
If you take the time you will notice that much of my reading focus is on marketing, business and sales. Part of that is me wanting to be better at what I do as a Network Engineer in an expanding market. But I won’t lie by saying that there isn’t a bigger plan to my reading madness and I look forward to sharing that with you all in the next few months. Until then what have you read and who have you met? Because 10 years from now what you start doing today could change your life.
Winbook 37T1 and Sony RM-AV3000 THANK YOU GOD!
Nice and simple post. After 3 years of Having our Winbook 37T1 LCD Which as been a great Cheap TV. I Paid $399 New for it. And 2 Years of having my Sony RM-AV3000 that I traded a set of JBL PC speakers for I can say that they work together.
Tonight I just sat down and kept trying likely codes until I found that it responded to the Samsung TV Code 8026 for the Sony RV-AV3000. I hope this gets indexed and helps some other folks. I know from reading on AVS forum that some of these TVs respond to Tatung codes but in my case it did not.
