Watch Wolfwalkers on the Apple TV app. In this post, we are going to introduce a couple ways.Learn how to use your Mac and devices together. LetвЂ™s dig in deeper from the previous concepts of part 1 of this article where we learned some basic day to day commands like navigating around the directories, creating files, copying them, commands to manipulate text on your terminal windows, installing software packages on your system and playing with file permissions.For those who are totally new to MySQL, itвЂ™s a good start to have a local MySQL server setup on your computer to test and learn how it works.

Ifconfig eth0 192.168.1.13You can also use ifconfig to change your MAC address. LetвЂ™s change the IP address to 192.168.1.13.Upon running ifconfig we see the change reflected. Since I donвЂ™t have a wireless adapter, my output is as such.In order to change your IP address, enter ifconfig, the interface you want to change the address for and the new address you want to assign to it. As well as the mac address which I have blurred out.(lo is localhost and is always mapped to 127.0.0.1)Iwconfig: Checking wireless network devicesIf you have a wireless adapter, you can use the iwconfig command to gather crucial information such as its IP address, MAC address, which mode it is in and much more. Here we run ifconfig and we can see the IP address mapped to our 2 network interfaces: eth0 and lo.We can also see the netmask and a broadcast address of the network interface attached. Hence, it becomes important to know you to connect and interact with all of your network devices.LetвЂ™s get started with learning all the various tools and utilities to analyze and manage networks.The ifconfig command is one of the most basic tools for interacting with active network interfaces.

Dhclient eth0DNS is a service that translates a domain name like вЂњhackingarticles.inвЂќ to the appropriate IP address. This DHCP server assigns IP addresses to all the systems on the subnet and it also keeps log files of such.LetвЂ™s request an IP Address from DHCP, by simply calling the DHCP server with the command dhclient and network interface you would want to change the IP Address of.We can see the IP Address has changed from what we had manually given it earlier. Ifconfig eth0 downUsing DHCP Server to assign new IP AddressesLinux has a Dynamic Host Configuration Protocol (DHCP) server that runs a daemon вЂ“ a process that runs in the background called DHCP daemon.

The file is located in / etc/hosts. is CloudflareвЂ™s public DNS server, you could also use GoogleвЂ™s which is 8.8.8.8)Echo 'nameserver 1.1.1.1' > /etc/resolv.confThere is a file in our system called hosts which also performs domain name вЂ“ IP Address translation. We can see the change reflect when reading using cat. We can simply use nano or vim which are some of the common text editors Linux.Here, we are going to use the echo command and > to overwrite the resolve.conf file. Dig Further searching вЂњ hackingatricles.inвЂќ mail servers: dig hackingarticles.in mxSearching for the name servers: dig hackingarticles.in nsThe DNS server information is stored in /etc/resolv.conf, in order to change the DNS server we need to edit this file.

Nice -n -10 /usr/bin/ssh-agentThe renice command takes an absolute value between -20 and 19 and sets the priority to that particular level. LetвЂ™s increment the priority of /usr/bin/ssh-agent by 10 (increasing its priority) using the n tag. Unlike ps, the top also refreshed dynamically вЂ“ every 10 seconds.Changing Priority with the вЂњniceвЂќ commandWhen you start a process, you can set its priority level with the nice command. It displays the process ordered by the resources used. The primary tool to do so is ps.Simple typing ps in the bash shell will list down all the active processes.(PID stands for process ID and is unique for every invoked process.)Running ps command with aux, will display all the running processes for all users, so letвЂ™s run ps auxHere we can see PID, the user who invoked the process, %CPU the process is using, %MEM represent the percentage of memory being used and finally COMMAND which is the name of the command that has started the processAs we learned earlier, we can pipe the output of ps aux into grep and filter out the specific information we want.LetвЂ™s search for msfconsole (A popular interface to use the Metasploit framework) ps aux | grep msfconsoleIn some use cases when you want to know which process is using the most resources, we use the top command.

Simply type fg and then the process ID.(In order to see the background processes in your system simply use the command jobs)Often one might need to schedule processes to run at a particular time of day. (You can see the PID that is generated) nano hacking-articles.txt &If you want to move a process running in the background to the foreground, you can use the fg command. In order to stop these kinds of processes, we use the kill command.The kill command has 64 different kill signals, each signifying something slightly different.( 1 stands for Hangup and is designated to stop the process while 9 is the absolute kill, it forces the process to stop by sending its resources to /dev/null).And in order to force stop process 4378 kill -9 4378At times, you may want a process to run in the background, and we can do so by simply adding & to the end of the command.=LetвЂ™s run nano in the background. (increment it by 20) renice 20 6242At times, when a process exhibits unusual behaviour or consumes too many system resources, they are called a zombie process.

Set | grep HISTSIZEWe can change the variable values simply by typing out the variable and equating it to a new value but this new value will only be changed for this particular session, if you open a new terminal window it will change back to its default.After running this, youвЂ™ll see that when you press the up/down arrow keys to recall your previous commands, nothing happens since we changed to a number of commands being stored to 0. There are two types of variables, environment and shell, while the shell variables are only valid for the particular session, the environment variables are system-wide.You can view all your default environment variables by entering env into your terminal from any directory, like so: set | moreAgain, using piping the output to the grep command we can filter out the variables we want.As we can see the history size is set to 1000. Variables are just strings in key-value pairs. At 9:00pmUnderstanding environment variables is a must when trying to get the most from your Linux system, it is crucial to be able to manage them for optimal performance. While for jobs that occur every day, week, the crond is more suited.LetвЂ™s execute a scanning_script.sh at 9:30pm.

This way you can always undo your changes.LetвЂ™s echo the value into a text file name valueofHISTSIZE and save it in our working directory byAdding ~/ echo $HISTSIZE ~/valueofHISTSIZE.txtNow, just like last time change the value of HISTSIZE but now weвЂ™ll execute another command export.
