How To Block Access To Specific Websites from your Router using Tomato Firmware

Tomato firmware is a free, downloadable firmware for the Linksys WRT series and some Buffalo and Asus routers which provides vastly improved functionality over the stock firmware. One of the nice things about Tomato, assuming you have a router which it’ll run on, is that it provides a very configurable method of selectively blocking access to the net in general, specific applications or protocols, or even specific websites. So if you have youngish kids who have (largely) unsupervised access to a computer with a net connection, you can keep them away from social networking sites like facebook, myspace, habbo etc. pretty easily. Here’s how:

1.) Go to you routers web interface (http://192.168.1.1 on my setup) and click on Access Restriction

Tomato1

2.) Click on Add to create a new rule

Tomato2

3.) Untick Block All Internet Access to display the full options list, and set it up something like this:

Tomato3

In the above example I’m only blocking selected machines (so the wife still has access to facebook etc.) – the PC the kids have access to is 192.168.1.105, and my IP is 101 (so I can test the blocks on my machine before removing myself from the block list).

The blocklist uses regex sub-string matching to decide which sites to block as follows:

You can also block specific protocols (BitTorrent, eDonkey, LimeWire etc.) using the built-in IPP2P module, or via Layer 7 (Application Layer) deep packet inspection, which can detect and block traffic of specific types (World of Warcraft, FTP, Flash etc. etc.) regardless of what port they’re running on.

Mac OS X Cleaning temp files etc.

If you insist on running any maintenance tasks, you could run these commands in the Terminal:

WARNING! The “sudo rm -f” command is VERY dangerous, and can cause data loss if used incorrectly. Please, PLEASE, ensure that you type the commands listed below correctly, double and even triple check, I will not be held responsible if you hose your system.

1. “User-level” tasks that do not require a restart:

Run maintenance cron tasks

Code:

sudo periodic daily weekly monthly

Flush logs under your home directory

Code:

cd ~/Library/Logs
sudo rm -rf ~/Library/Logs/*

Flush cache under your home directory

Code:

rm -rf ~/Library/Safari/Downloads.plist
cd ~/Library/Caches
sudo rm -rf ~/Library/Caches/*

Flush Directory Service resolver cache (DNS, etc)

Code:

dscacheutil -flushcache

Update application pre-binding

Code:

sudo update_prebinding -root / -force

Repair disk permissions on boot volume

Code:

sudo diskutil repairPermissions /

Log out and back in to finalize the above steps.

2. “System-level” tasks that require a restart:

Clear the global cache database

Code:

cd /Library/Caches
sudo rm -rf /Library/Caches/*

Flush system cache entries

Code:

cd /System/Library/Caches
sudo rm -rf /System/Library/Caches/*

Flush LaunchServices Database (helps with multiple “Open With” entries)

Code:

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

Flush Apple Type Server (ATS) cache (resolves issues with corrupt fonts some times)

Code:

sudo rm -rf `lsof | grep com.apple.ATS/annex.aux \
| grep Finder | cut -c 66-139`
sudo rm -rf /private/var/folders/*/*/-Caches-/com.apple.ATS

Repair disk permissions on boot volume

Code:

sudo diskutil repairPermissions /

Finally, restart your Mac after completing any system-wide maintenance tasks.

OS X Mavericks: Methods for Starting up Your Mac

Normally you can restart your Mac by choosing Apple menu > Restart. However, in some cases—for example, if the pointer freezes on the screen or the Mac becomes unresponsive—you may have to use one of the startup methods listed here.

You can use these key combinations when you start up your Mac. Unless otherwise specified, hold down the specified key immediately after you hear the startup tone (while the screen is still black).

Action Shortcut
Manually restart Hold down the power button on your Mac until it shuts off. After a moment, press the power button again to start your Mac. You may lose unsaved changes in open documents.
Prevent automatic login When you see the progress indicator (looks like a spinning gear), hold down the left Shift key.
Prevent login items and Finder windows from opening when you log in After clicking the Log In button in the login window, hold down the Shift key.
Start up from a CD or DVD C
Start up from the default NetBoot disk image N
Start up in target disk mode T
Use Apple Diagnostics or Apple Hardware Test D
Use recovery tools Command (⌘)-R
Select a startup disk Option

To open the optical drive when choosing a startup disk, press Command (⌘)-Period (.).

Eject removable discs Hold down the mouse or trackpad button.

Hold down the Media Eject key (⏏) or F12 key.

Reset parameter RAM Option-Command (⌘)-P-R
Show detailed status messages (verbose mode) Command (⌘)-V
Start up in single user mode Command (⌘)-S
Start up in Safe Mode (Only essential OS X items are started; some features and apps might not work correctly.) Immediately after you hear the startup tone, hold down the Shift key. Release the Shift key when you see the progress indicator (looks like a spinning gear).

How to Use Screen Video Capture on Your Mac

Not sure when this feature got added, but since this was new to me, I thought this was worth sharing.

Launch QuickTime Player (it’s in your Applications folder). Now select New Screen Recording from the File menu, or type control-command-N. A small screen recording window will appear, like so:

recorder

Click the little triangle on the right side of the window to adjust the microphone and mouse click options. When ready, click the record button in the center of the window. Click and drag a section of the screen to record part of the screen or just click to record the entire screen. Once you do that, click to start recording. Click the stop button that appears in the menu bar to stop recording.

Pretty easy, and the end result is a QuickTime movie you can use anywhere you’d expect (iMovie, YouTube, etc.) Clearly not a method a pro would use, but if your needs are relatively simple, this is a great solution.

Mac Boots to Black Screen But Can See My Cursor

1. Shut the computer down by holding the power button for 10 seconds

2. Restart the computer and press shift at the same time until you see the progress bar start moving

3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.

4. After a moment, you should see the spinning beach ball

5. Your screen should then move on to something along the lines of “Completing OSX Installation” (I can’t remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn’t working, but the screen was just sleeping).

Apparently, it’s an issue with an automatic update that never quite got past the login screen.

Also may need to do a Pram reset:

A small amount of your computer’s memory, called “parameter random-access memory” or PRAM, stores certain settings in a location that OS X can access quickly. The particular settings that are stored depend on your type of Mac and the types of devices connected to it. The settings include your designated startup disk, display resolution, speaker volume, and other information.

Note: To print these instructions, open Help Viewer’s Action pop-up menu (looks like a gear), then choose Print.

Shut down your Mac.

Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.

Turn on your Mac.

Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.

Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.

Release the keys.

Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.

How to Create Gmail Filters

Occasionally, email does not behave the way it’s supposed to. A spam message may be allowed into your inbox or, worse, a valid email you need in order to effectively do your job might get filtered and sent to your spam box. The solution, if you use a Gmail or Gsuite email address, is to use filters.

Log into your email in a web browser such as Google Chrome and click on the gear icon in the upper right corner just below the colored circle with your first initial in it.

Choose Settings from the drop down menu and then choose Filters and Blocked Addresses from the tabs across the top.

Click “Create a new filter” (this is located below any existing filters and above the blocked email address list).

In the box that appears, you have several options to choose from. You can set any combination of From Address, To Address, Subject, Key Words etc.

Once you have entered the criteria for your filter, click create filter at the bottom of the pop up and you will be able to choose how Gmail handles messages matching your search. Again, you have several options including skip the inbox, mark as read, star it, apply a label, forward or delete the message, never send it to spam, always or never mark the message as important or categorize.

Example: You might have found yourself on an email list for a marketing company that sends you messages multiple times a day. You aren’t interested in what they are selling and you can’t seem to unsubscribe. Create a filter! Using the sending address as the filter criteria, you can tell Google  to delete the message.

Alternatively, you might get so many emails from your manager that Gmail treats some of them as spam. In this case, you could create a filter based on their email address to Never send to spam and you can make sure you’re always getting important emails.
