Internet (web) without Google (aka Block Google IP addresses)

September 12th, 2015 Alex Posted in internet Comments Off on Internet (web) without Google (aka Block Google IP addresses)

Block Google, completely

  1. Find Google IP addresses ranges

  2. When you need the literal IP addresses for Google Apps mail servers, start by using one of the common DNS lookup commands (nslookup, dig, host) to retrieve the SPF records for the domain, like so:

    nslookup -q=TXT

    This returns a list of the domains included in Google’s SPF record, such as:,,

    Now look up the DNS records associated with those domains, one at a time, like so:

    nslookup -q=TXT
    nslookup -q=TXT
    nslookup -q=TXT

  3. Create iptables/ip6tables rules:

  4. Add this to a bash script:

    # /etc/init.d/firewall

    # Block Google
    $IPT -A INPUT -s -j DROP

Super Wi-Fi – Wikipedia, the free encyclopedia

Super Wi-Fi

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Super WiFi,or IEEE 802.22 and IEEE 802.11af as it’s Technically known, is a term coined by the United States Federal Communications Commission (FCC) to describe a wireless networking proposal which the FCC plans to use for the creation of longer-distance wireless internet.[1][2] The use of the trademark “Wi-Fi” in the name has been criticized because it is not based on Wi-Fi technology or endorsed by the Wi-Fi Alliance.[1]

Instead of using the 2.4 GHz radio frequency of Wi-Fi, the ‘Super Wi-Fi’ proposal uses the lower-frequency white spaces between television channel frequencies.[3] These lower frequencies allow the signal to travel further and penetrate walls better than the higher frequencies previously used.[3] The FCC’s plan is to allow those white space frequencies to be used for free, as happens with Wi-Fi and Bluetooth.[3]

Choosing Passwords Tip

June 23rd, 2011 Alex Posted in internet, security Comments Off on Choosing Passwords Tip

Set up 4 to 6 passwords:
one for all the low-security sites,
another for any site that has your credit card number,
another for social networking,
another for email,
another for work,
and the most secure for your banking sites. Sleep better.

Keep them on a piece of paper somewhere safe like your wallet.

These rules are not always possible, but they help reduce the numbers of passwords while staying fairly secure.

It can be difficult to remember every sites that you used if you decide to update your passwords, but what I do is keep the latest two versions of my passwords handy.

The default value is 2 seconds. 20 seconds should be okay in most cases.

If the IRC client supports server passwords, you can also identify automatically and more quickly by using YourUsername:YourPassword as your server password. (It is quicker then using the “/msg nickserv identity password” command so you should be identified by the time the auto-join happens).

Digi Watchport/H USB Serial Humidity/Temperature Sensor in Linux

August 19th, 2009 Alex Posted in electronics, internet, linux Comments Off on Digi Watchport/H USB Serial Humidity/Temperature Sensor in Linux

Using Digi Watchport/H USB Serial Humidity/Temperature Sensor in Linux

Ubuntu 9.04 has everything you need except for minicom. So all I had to do was to:

  • plug it in

    dmesg should get you the following output:

    usb 2-9: new full speed USB device using ohci_hcd and address 50
    usb 2-9: configuration #1 chosen from 1 choice
    io_ti 2-9:1.0: Edgeport TI 1 port adapter converter detected
    usb 2-9: Edgeport TI 1 port adapter converter now attached to ttyUSB0

  • Install minicom: sudo apt-get install minicom
  • Edit minicom settings: ~$ minicom -s
    1. Change the Serial Device to /dev/ttyUSB0

    2. Change the Bps/Par/Bits field to 9600 8N1, (9600 baud, 8 bits, no parity, 1 stop bit). These are the default settings used by the Linux kernel; they can, if necessary, be overridden from the kernel command line by adding extra parameters to the console= option. See kernel-parameters.txt and serial-console.txt.

    3. Turn off both Hardware Flow Control and Software Flow Control.

    4. In the Modem and dialing menu, remove the Init string and Reset string completely if required.

    5. Save your new config
    6. start minicom
    7. more details
  • Use one of the following commands:
    Command Description Return Value
    ?<CR> Tells about the command set available for this Watchport as described in this section
    I<CR> Tells what kind of Watchport is connected. Watchport/H<CR>
    H<CR> Gives the percentage relative humidity. 38%<CR>
    T<CR> Gives temperature in Celsius. +22.2500C<CR>
    TC<CR> Also gives temperature in Celsius. +22.2500C<CR>
    TF<CR> Gives temperature in Fahrenheit. +72.0000F<CR>
    TF+<CR> Repeats the TF command every 3-4 seconds until the next keystroke. Appending + also works with the TC and H commands +72.0000F<CR>
    L4<CR> Adjusts the slew rate of the data line. When “L” is followed by a numeric value, 1 through 8, Watchport responds with OK. Other values return Invalid Command. The default setting is 4. Adjust the parameter until the data transmission becomes error-free. The setting remains in effect until the Watchport is power-cycled. OK

Download Watchport’s manual

Now all I need is a perl script to automate the posting of these values to twitter?
