I’ve implemented plenty of ASA 5525-X firewalls with the integrated IPS software module. While the legacy Cisco IPS module does what it’s intended to do, it leaves a great deal to be desired in terms of customization and usability. That’s why I’m very excited to try out Cisco’s new ASA with FirePOWER services. This is the SourceFire implementation when Cisco bought them back in mid-2013. SourceFire was at the top of their game when Cisco bought the company out for $2.7 billion. So it will be very exciting to see how it turned out. NSS Labs performed preliminary testing and found that the ASA/SourceFire combo was more affective at stopping malware than any other vendor including Fortinet and Palo Alto. Looks like good times ahead for Cisco network security in 2015!
I ran into an issue when troubleshooting with Cisco TAC which required I take some packet captures using a SPAN port off a Cisco switch using Wireshark. Wireshark is the de-facto packet capture program out there. It’s free, powerful and it works really well. I’ve never had a problem with it until recently. And in all fairness, it wasn’t a problem with Wireshark, but with the AV software installed on my Windows laptop. If you find yourself taking captures and only seeing the initial Syn or Ack coming back…and you have ESET security on your laptop like I did, then you will find this useful. First, disable your ESET protection completely. You’ll need an administrative password for the software to do so if you are in an enterprise environment.
If you’re like me, I always forget the command needed to see hashed passwords on Cisco ASA’s. This is especially useful when you’re making changes to VPN tunnels. In any case, here is the command you need:
Rush Limbaugh is one of the most polarizing figures in America. As a fellow tech geek, I love to hear his comments on Apple products and the company as a whole. And even if you don’t agree with Rush’s politics, he’s dead on when it comes to his opinion on everything Apple.
If you’ve been having problems with getting Java 7 applications to run while connected to Cisco Anyconnect version 3.0 or 3.1 you’re not alone. There is an issue with how Java 7 handled IPv6 that causes it not to run within the VPN tunnel. Fortunately, there are some workarounds.
Love them or hate them, technology buzz words are here to stay. Often they’re helpful to get people interested in a new technology. But other times, a buzzword becomes so overhyped that it becomes loathed. The term “cloud computing” nearly became a hated buzzword a few years ago, simply because everyone used it, but didn’t really know what it meant. Over time however, people eventually learned the true power of the cloud and the term was accepted because it became a legitimate technology to the IT community.
One of the major differences between 802.11n and all previous WiFi standards is the fact that 802.11n can operate within a 20 MHz channel like 802.11a/b/g — or it can consume two consecutive channels for double the bandwidth! With twice the bandwidth, it seems like everyone should configure 802.11n to operate in a 40 MHz channel, right?
Not exactly. The problem is, when you consume two channels, you end up shrinking the number of non-overlapping channels available. If you enable 40 MHz channels in the 2.4 GHz spectrum, you only have two non-overlapping channels to choose from – as opposed to three when using 20 MHz channels. That means your likelihood of interference increases dramatically. In the 5 GHz spectrum, things are a bit better as you shrink your non-overlapping channels from 23 down to 11. In fact, the use of 40MHz channels at 5GHz will increase the coverage area at higher data speeds.
Now that it’s Christmas 2012, the 7 inch tablet market has reached a fever pitch. We now have high-end devices (with mid-range prices) like the Samsung Galaxy tab, Google Nexus 7, Amazon Kindle Fire HD and even the Apple iPod mini are the talk of the town. But there’s one little tablet that’s been around for a long time now that just won’t go away. The Nook Color. And despite the Nook Color falling behind in the specifications department, it’s still fully capable and highly hackable — which makes it a tech geeks go-to tablet despite all the newcomers. After all, it is one of the only tablets out there with an micro-SD card slot. And to top it off, there are great deals on the Nook Color — everything from new units going for $99 on Black Friday, to refurbished units going for $79 online. In my opinion, the Nook Color is a perfectly capable tablet that’s going to find it’s way into plenty of Christmas stockings this year. And if you’re looking for something to tinker around with, for under $100, you can’t go wrong.
From the looks of it, enterprise owned and operated WAN acceleration and optimization appliances are quickly becoming a extinct. One recent example is Ecessa Corp., a manufacturer of WAN acceleration hardware appliances. Seeing the writing on the wall, the company decided to pivot from their focus on hardware manufacturing and sales to a WAN acceleration services and support model. Ecessa will continue to sell hardware, but consider it to be “legacy” arm of their new business strategy. Future customers and revenue streams are expected come primarily in service form that will be sold through their existing VAR network.
WiFi is easy — as long as you have the wireless spectrum all to yourself. For most, people’s experience with WiFi is simply a matter of going to their local Best Buy, buying a consumer grade wireless router and plugging it in at home. If they live in a suburban area where the houses are fairly separated, these people really don’t have much to worry about in terms of interference.
After reading about the search engine result doctoring that Google seems to be taking part in these days, I finally decided that after twelve years using Google search exclusively, it was time to try out a new search engine. Clearly, the next in line behind Google search in the United States would be Microsoft’s Bing. So I made the switch to Bing as my go-to search engine.
Someone asked me today: which one should i get, the Nook Color or the newer Nook Tablet? I had to scratch my head a bit because I didn’t realize that Barnes and Noble still even sold the Nook Color. But I checked, and sure enough, the Nook Color can still be bought for $199 while the Nook Tablet is going for $249.
The CyanogenMod team is at it again. This time, they’re taking on Androids’s recently released 4.0 software — otherwise known as Ice Cream Sandwich. The Ice Cream Sandwich version of CyanogenMod will be known as CyanogenMod 9 or simply CM9.
But let’s not get too excited just yet as the CM team has stated:
I finally received the Nokia N9 upgrade notification on my phone on November 23rd while in Bangkok Thailand. I knew that I could have download the update onto my computer and performed a manual install off of the USB earlier but I wanted to see how the OTA upgrade worked.
I was doing some traveling on the 23rd and wanted to be in a spot where I had a WiFi connection as was recommended by Nokia. So I had to wait a full 24 hours until I was back at home. Once there, I performed the recommended backup and then pressed the update software button. But nothing happened.
Nothing in life is perfect and that even goes for the Nokia N9. I’ve already admitted in previous blogs that I love my N9. But…I do have some complaints at the same time. For one, the Facebook app is pretty weak sauce. It’s horribly slow and you are often presented with the now famous black screen with the: “FacebookQML not responding” message. After 10 seconds or so, the app kicks back in but it’s very annoying. Also, the Facebook app lacks the ability to check-in and really seems outdated compared to the iOS Facebook app.
Many people are currently in the same boat that I was. You’ve been using the iPhone for years and feel like you’ve spent so much time with iTunes creating all your playlists that it would be a shame to not be able to use them again. So much so that it is causing you to rethink your plans to buy the super-cool Nokia N9 because it doesn’t play nice with iTunes.
I finally put my money where my mouth was when I previously stated that the Nokia N9 was the most interesting smartphone of 2011. When Apple finally announced the iPhone 4S, I honestly was a little let down with their offering. After all, nobody I know was asking for a faster processor, marginally better camera and voice recognition with a slightly modified OS. Instead, I was looking for something completely different from end-to-end and the Nokia N9 does exactly that.
To start, the hardware of the N9 is absolutely first rate. Nokia has been in the hardware “biz” for a long time now and it really shows. The phone is very light, yet it feels like you could drop it without any worries. For those of you that are really concerned, Nokia was nice enough to include a protective silicone case. The great thing about this particular case is that it really becomes part of the phone as it fits very snugly and doesn’t add any unnecessary bulk. Also included with the N9 is a pair of headphones, USB charger and AC adapter.
I realize I”m a little late to the party in talking about the Kindle Fire. But I thought I’d briefly add my two cents. On first glance of the new 7 inch color tablet from Amazon, I’d say it’s very much like the Nook Color…only crippled. Yes, clearly the Fire has a much more powerful dual-core processor compared to the single-core processor found in the NC. Additionally, the Fire runs Android 2.3 Gingerbread right out of the box while the Nook is still running Froyo 2.2.
Ever sicne Slashdot posted a story regarding the “hidden” Wi-Fi Diagnostic tools found in OS X Lion, I’m getting lots of questions on how to use it. First of all, the tools aren’t secret or hidden but simply not documented or highly advertised. In fact there’s lots of really interesting tools and utilities in OS X that you probably aren’t even aware of.
Most of us have already heard about Amazon’s upcoming Android tablet…But did you know that Barnes and Noble is also rumored to release the Nook Color 2 in just a few weeks? Not only that, but I just read today that Lenovo is also expected to release a budget tablet very soon as well.
