+===== ifupdown vs. ifconfig =====
+**Debian, overview:**
+  * ''ifup'' and ''ifdown'' control interfaces that are listed in ''/etc/network/interfaces''.
+  * ''ifconfig'' directly controls network interfaces (much like the newer ''ip'' command)
+**The** ''ifupdown'' **package:** high-level network configuration
+  * The ''ifup'' and ''ifdown'' commands may be used to configure or deconfigure network interfaces based on interface definitions in the file ''/etc/network/interfaces''.
+  * Example: bring up the network with ''ifup eth0'' based on eth0 configuration in ''/etc/network/interfaces''.
+  * ''ifupdown'' will wrap ''ifconfig'' with the network configuration files (i.e., ''ifdown'' or ''ifup'' will execute ''ifconfig down'' or ''ifconfig up'' inside it). That means:
+    * ''ifup eth0'' will fetch the interface config file and bring up the interface with the correct IP address, mask, routes etc.
+    * ''ifconfig eth0'' up would just start the interface **//with no IP//**, etc. (important for sniffing in monitor mode because you don't want an IP address, etc.; you want an open broadcase).
+**The** ''ifconfig'' **command:** a low-level network command (and deprecated, sadly)
+  * An ''ifconfig up eth0'' activates eth0 but does not setup IP addresses, etc.
+  * An ''ifup eth0'' sets up IP addresses and other options based on the interface's configuration in ''/etc/network/interfaces''.
 ===== ip command =====

 **Usage of the** ''ip'' **command:**
   * If your distro did not install ifconfig, you can install it in Debian with ''apt install net-tools''.
-  * Or you can use the horridly ugly syntax for ''ip'' (complex and hard-to-understand help can be found [[https://www.howtogeek.com/657911/how-to-use-the-ip-command-on-linux/|here]]).

   * From the following example you will need to replace the IP and the interface with your own.

+  * ''ip'' (like the old net-tools ''ifconfig'' stuff) interacts with ''/etc/network/interfaces'', so put all your network configuration information there and just up/down your network with these commands:
+<code>
+/etc/init.d/networking restart  # Restarts network interfaces, or stop/start...
+/etc/init.d/networking stop     # Stops network interfaces
+/etc/init.d/networking start    # Starts network interfaces
