Calculating file checksums on an OS X system

If you need to calculate a checksum, aka cryptographic hash value or digital fingerprint, on a Mac OS X system, you can use the md5 command to calculate a MD5 checksum, which is equivalent to the md5sum utility on Linux systems, and the shasum command to calculate Secure Hash Algorithms (SHA). The default value for shasum, if no algorithm is specified, is Secure Hash Algorithm 1 (SHA-1), but you can specify other algorithms, such as Secure Hash Algorithm 2 (SHA-2), e.g. SHA-256, using the -a option. E.g. -a 256 for SHA-256.

Viewing DHCP information on an OS X system

If you want to determine the IP address of the DHCP server from which a Mac OS X system received its IP address, subnet mask, etc., you can obtain that information from a command-line interface (CLI), i.e., a Terminal window by using the command ipconfig getpacket interface where interface is the relevant network interface, which will usually be en0 or en1. You can issue the command ifconfig -a in a Terminal window to see the network interfaces on the system and which have IP addresses assigned to them.

getpacket interface-name
Prints to standard output the DHCP/BOOTP packet that the client accepted from the DHCP/BOOTP server. This command is useful to check what the server provided, and whether the values are sensible. This command outputs nothing if DHCP/BOOTP is not active on the interface, or the attempt to acquire an IP address was unsuccessful.

OS X - Get File Info

On an OS X/macOS system, you may be able to determine a file's origin, i.e., where it was downloaded from, by right-clicking on the file, or clicking on it to highlight it and then hitting command-I (the command and "I" keys), in the Finder and choosing Get Info. If a "where from" field is displayed, you can see the URL from which the file was obtained if it was downloaded from a website. You can also view that information from a command-line interface (CLI), e.g., a Terminal window, using the mdls command.

Modifying search domain settins under OS X

If you would like to be put a system's name in your web browser, e.g., ajax, into your browser's address bar and have the system automatically append a domain name, e.g. example.com, so that the browser attempts to access ajax.example.com, even though you just typed ajax, you can modify the Domain Name System (DNS) search domain settings. To do so on an Apple OS X/macOS system, take the following steps:

  1. Click on the Apple icon at the top, left-hand side of your screen.
  2. Choose System Preferences then Network.
  3. Select the relevant network service, such as Wi-Fi or Ethernet, then click on the Advanced button.
  4. Click on DNS.
  5. Click in the Search Domains box and then click on the "+" at the bottom of that box to add a new search domain.
  6. Type the name of the search domain, e.g. example.com.
  7. Click on OK

You can add multiple domains; domains will be searched in the order you list them with the search starting at the topmost entry and continuing down through the list of domains with the search stopping when a valid name is found.

Installing Lynx with Homebrew

If you need a text-based web browser that doesn't require a graphical user interface (GUI), one alternative is the Lynx browser that is available for a variety of operating systems, including Linux, OS X/macOS, DOS, and Microsoft Windows. If you have the Homebrew package management software installed on a OS X/macOS system, you can use it to easily install the Lynx browser using the command brew install lynx.

Advantages to using a text-based browser such as Lynx, in addition to it not requiring a GUI, making it suitable to be run in a Terminal window, is that it doesn't support Adobe Flash, which makes it invulnerable to malware distributed through vulnerabilities in Flash. Also, because it doesn't support JavaScript nor graphics, it prevents tracking software that uses JavaScript or web bugs, aka web beacons, which can track your web browsing activities via small graphics files that will be invisible to you on a webpage, from being used to track your browsing activities. It does support HTTP cookies, though, which are also used by sites to track visitors, but Lynx will prompt you if you want to allow cookies for a site when you visit the site and has whitelisting and blacklisting capabilities. E.g., when a site tries to place a cookie on your system, Lynx will prompt you as to whether it should be allowed. You can choose from "Y/N/Always/neVer."

Determining the version of Firefox on OS X

If you wish to determine the version of Firefox installed on an OS X from a command line interface (CLI), you can open a Terminal window and use the command shown below:

$ /Applications/Firefox.app/Contents/MacOS/firefox -v
Mozilla Firefox 45.8.0
$

You can also find the information in the Info.plist file found at /Applications/Firefox.app/Contents/Info.plist. The version number will be on the line following the "key" line for CFBundleGetInfoString and also after the "key" line for CFBundleShortVersionString .

        <key>CFBundleGetInfoString</key>
        <string>Firefox 45.8.0</string>

        <key>CFBundleShortVersionString</key>
        <string>45.8.0</string>

Can't Force Quit Firefox

Firefox (version 45.8.0) became unresponsive on my MacBook Pro running OS X El Capitan (10.11.6). I killed Firefox by clicking on the Apple icon at the top, left-hand corner of the page and selecting Force Quit and then selecting Firefox in the list of running applications and then clicking on the Force Quit button.

Force Quit Applications - Firefox

I then restarted Firefox by clicking on its icon in the Dock. The icon bounced a few times and then stopped, so I assumed Firefox was now running. But when I tried accessing it by holding down the command while repeatedely tapping the tab key to cycle through the open applications, it didn't appear. Nor did it show up in the list of running processes shown by the Activity Monitor.

Firefox in Force Quit Applications, but not in Activity Monitor

Firefox stopped responding whenever I attempted to access a site. I could verify network connectivity to various sites with ping, but if I attempted to access a URL in the Firefox browser on my MacBook Pro running OS X El Capitan, Firefox (version 45.7.0) would not display any webpage. I've had this problem in the past; when it occurred, I would quit Firefox, sometimes using Force Quit Applications, which is available by clicking on the Apple icon at the top, left-hand corner of the screen and then selecting Force Quit and then selecting Firefox from the Force Quit Applications list of running applications and then clicking on the Force Quit button. When I did that today, I saw the message below as usual:

Do you want to force "Firefox" to quit?

You will lose any unsaved changes.

 

I clicked on Force Quit, but that seemed to have no effect. I closed and reopened Force Quit Applications and went through the same process numerous times, but no matter how many times I repeated the process, Firefox remained in the list of running applications that it showed.
