Tried to capture packets for a NAT address (192.168.2.0/24 is NAT Pool) for my VMWare Fusion session. When on my mac I ran the following command I'm getting some weird error messages. dennis$ sudo tcpdump -i any -v network 192.168.2.0/24 tcpdump: data link type PKTAP tcpdump: listening on any, link-type PKTAP (Apple DLT_PKTAP), capture size 262144 bytes pktap_filter_packet: pcap_add_if_info(en9, 1) failed: pcap_if_info_set_add: pcap_compile_nopcap() failed pktap_filter_packet: pcap_add_if_info(bridge100, 1) failed: pcap_if_info_set_add: pcap_compile_nopcap() failed pktap_filter_packet: pcap_add_if_info(en0, 1) failed: pcap_if_info_set_add: pcap_compile_nopcap() fail…

So yes Mac OS X is built on one of the most secure operating systems (Linux) which is used for the majority of servers we depend on and need to be up and running for days, weeks, months and even years without having to reboot. Many articles tell you how you don't need to worry about AntiVirus and/or Adware programs but I have a different feeling. Yes Mac OS X is very secure but all it takes is clicking on something that appears to be legit and entering in your password for your Mac allowing that software to infiltrate your clean Mac without you even knowing. My suggestion is run two tools to help keep your Mac clean. 1. Malwarebytes (ANTI-MALWARE) for Mac 2. ClamXav …

So how to locate or update or refresh or rescan iTunes library? Easy-Fast way (not always successful) First quit iTunes app. Re-launch iTunes app while holding down the Option key. Select “choose library.” Go the iTunes folder and choose it. Another method that always works for me (just takes forever) Launch iTunes app on your computer Navigate to File -> Add to library Select the location of your iTunes library (ex: iTunes folder) iTunes app will relocate or refresh all meta data and files you already have to library. Don’t worry it won’t recreate duplicate files.

Anytime I try and upgrade my iWatch it says it can't because there is no internet connection. I verified I have internet connection. I also went to airplane mode and just had WiFi and Bluetooth, validated my internet (WiFi) worked and still won't upgrade. Any ideas?

So its not really a virus but a Trojan which means it disguises itself to be something else like Adobe update or another software update that you may have and you click update and enter your password and install the Trojan. No one has yet to come up with a Virus which is a malicious piece of software that gets installed on your Mac OS X that you don't know about it or haven't authorized. The Flashback Trojan, also called BackDoor.Flashback.39, was initially discovered as a fake Adobe Flash Player plug-in installer in September 2011. Check with this tool:FlashbackChecker.1.0.zip Remove: CNET Step by Step

iOS Roaming Trigger threshold The trigger threshold is the minimum signal level a client requires to maintain the current connection. iOS clients monitor and maintain the current BSSID’s connection until the RSSI crosses the -70 dBm threshold. Once crossed, iOS initiates a scan to find roam candidate BSSIDs for the current ESSID. This information is important to consider when designing wireless cells and their expected signal overlap. For example, if 5 GHz cells are designed with a -67 dBm overlap: iOS uses -70 dBm as the trigger and will therefore remain connected to the current BSSID longer than you expect. Review how the cell overlap wa…

Sometimes its helpful to know what ports on your Mac are in LISTENING status. So here are a few commands that I found helpful in my quest to find what ports are open. $ netstat -atp tcp | grep -i "listen" tcp4 0 0 *.irdmi *.* LISTEN tcp4 0 0 localhost.49155 *.* LISTEN tcp4 0 0 localhost.49154 *.* LISTEN tcp4 0 0 localhost.49153 *.* LISTEN tcp4 0 0 localhost.49152 *.* LISTEN tcp4 0 0 *.kerberos *.* LISTEN tcp6 0 0 *.kerb…

With the introduction to El Capitan they removed the disc burning ability from the Disk Utility which is where most of us went to burn an image. So from El Capitan (10.11) and newer (or until they change it again) the below will be the way to do it. But no worries, they didn't take it completely away, more of relocated it. Open Finder and click once to highlight the image you want to burn. Then click Burn Disk Image "blah blah blah" to Disc... the Burning process will begin.. as long as you have your blank media in the drive.

There comes a time that the DNS server(s) do not have the name to address resolution you need so just add it to your local hosts file. Mac OS X 10.2 or later Edit the /private/etc/hosts file. For more information on how to use the hosts file, open Terminal and type: man hosts Note: Editing this file requires root privileges. I suggest typing while in Terminal sudo nano /private/etc/hosts It may be a good idea to flush the DNS Cache that is running by then typing the following after you save the hosts file dscacheutil -flushcache

Switching operating systems is a scary and can be exciting adventure. It can also be a major pain in the butt. I am not author of any book but hope I can help fill in some blanks.

Here are some basic things you may or may not know. Open Applications... In Windows you click the Start button - Click on Programs - Select Your Application In Mac OS X you click the Finder (looks like a smiley face) - Click on Applications - Select Your Appl…

I am curious as to what I should do when I can not click on FInder (it just makes a sound everything I click on it like something is in the background waiting for me to answer it but I can't seem to find anything). I can not open a new window and I'm not able to click on the apple to do a restart. Someone said to open terminal and type something like: sudo -h shutdown now but i can't get to Terminal. You could click on spotlight and type Terminal and it will find it for you at which time you could just double-click on. As far as shutting down or restarting your system you could do either without clicking on the apple, just as long as you can open up your terminal windo…

One way to store or group files on a Mac is to create a Disk Image. A Disk Image is a file which has the properties of a separate hard drive or CD. It has a size limit and options for encryption to keep your files safe and secure. This how-to will work with Mac OS X. Steps Create a New Folder and place the files you would like in your disk image into this new folder. Right click (or CTRL-Click) the folder and select "Get Info" and note the size of it's contents. Open Disk Utility (Applications > Utilities > Disk Utility) Click the "New Image" icon to create a new disk image. Enter a name for the Image, and select a size adequate for the size of …

Your bad kitty will run faster and smoother after it sheds a few gigabytes. A slimmer cat is a faster cat, and we'll bet dimes to DIMMs that you can shed several gigabytes from your Mac's hard drive without missing them. If you installed the default Mac OS10.4, for example, you've got 1GB of foreign language translation support, 2.1GB of printer drivers, and 9.9GB of bundled software. Once you've removed the biggest offenders post facto by following the steps below, take an hour to browse your hard drive for such junk as sample or stock images in Photoshop and sample songs in GarageBand (they're in /Users/username/Music/), and of course,s cour your iTunes library for all…

Tweak processor priorities and RAM usage where available Mac OS X is a masterfully multithreaded system with the ability to run and manage hundreds of tasks simultaneously, including tasks that you've initiated (a Final Cut Pro render, a Photoshop filter, a spell-check in Word -- anything) as well as oodles of background daemons, enless Spotlight indexing, and other noise. It's your Mac, so you get to decide which apps get processor priority and when -- it's known as niceness in the Unix world. Make iMovie nicer as it chews on your epic film while you write your acceptance speech in Word, or lash Photoshop to morrings of your specifications if that's where you spend the …

The Mac is rightfully revered for the beauty, power, and simplicity of its graphical user interface. Indeed, it was the release of the first Macintosh that brough the concept of pointing and clicking to the average computer user. But in addition to the point-and-click ease of the OS X Finder, your Mac sports on of the most powerful command-line interfaces on the planet: the Terminal. Mac OS X comes with hunderds of Unix programs - and you can get them all through the Terminal. As much as we love the ease of the GUI, the power of the Terminal is hard to beat. It allows you to do many things faster than you could using the GUI - and in some cases, it even lets you do things…

nmap is the key... If you do not have nmap installed, then I suggest installing it. The best way to get this installed is using a program called fink. Note: You'll need to enable root user for nmap to work and know root password Once installed, open a terminal window and type fink install nmap (you'll have to type in your password just like you do when you install any program) Now that nmap is installed, run the following command nmap -sP -T Insane 192.168.1.1-254 You should get an output like: You can also run Check out the GUI version of nmap for your Mac called Zenmap (most excellent tool)

I realize I could use the Network Utility to do most of what typical troubleshooting does but I am more familar with the command prompt. When I use Windows I run my ping, tracert, nslookup, nbtstat, netstat and ipconfig. I would like to know the common commands I would use on my lovely mac for the same functionality and then some. So in short, compare the Apple Mac OS X Network Utility and Windows command prompt to what I can do in the terminal to match or beat what the others offer (which I know it can). Okay, tall order but I believe I can get this started. Network Utility - Info Mac OS X: $ifconfig Network Utility - NetStat: $netstat Display routing table in…

I've been hunting around the internet looking for a solution on why I am unable to burn DVD's again. Here are a list of three solutions that worked for different people 1. Try different media (verbatim is the preferred media by many users) 2. Drive Cleaning Kit (usually a DVD or CD with brushes) 3. This one is weird but it involves doing the following: Open System Preferences. Click on "International" Under "Languages": Drag any of the other languages to the top, then drag English back to the top. Set "Order for sorted lists" to English Set "Word Break" to English (United States, computer) Close System Preferences Restart computer What worked for me was shutt…

I am a firm believer in having backups of my system even though in the three years I have owned my MacBook Pro and the six years I have owned my Powerbook G4 laptop, I have not had one hardware issue (even with a full cup of coffee spilled on my MacBook Pro). With one purchased program (SuperDuper for $30 so you have the scheduling capability) you can autoset your Mac to startup and run a full backup of your system. First install SuperDuper if you haven't done so already and next let's setup the Mac to startup automatically. I have mine start at 5:00am and have the backup startup by 5:30am and when I start working at 6:00am I am running with a full backup before the day…
