What are network commands?
To understand networking commands, one must understand ‘network’ and ‘commands’ separately. Networking is the exchange of information from one network to the other, and computer networking is a way to link various devices to share information. Many basic commands are used; these commands are separate according to different requirements. The network command is when a user gives the command to the device, and the device responds by showing a relevant result.
Many network commands like Linux are commonly used for monitoring when the computer system is facing some problem or troubleshooting the problems. The list of these utility commands is very long, repeated according to usability. Some of the very common commands are Ping, IpConfig, Tracert, Hostname, NSLookup, Netstat, or Nbtstat.
Linux network troubleshooting commands
Today, monitoring and securing a system has become essential. Linux operating systems and problem-related to them, many network Linux commands are used to resolve these Linux network troubles with the simple use of the most common network commands, Linux.
Linux is an open-source operating software system. Most basic Linux network troubleshooting commands used to manage, operate and resolve Linux system when a networking system shows some issue are:
Ping, This is an effortless command and most commonly used to check a host’s status. This easiest command shows if the host is alive and if it responds to the user’s command. The two highlighting tasks of ‘ping command’ are to check for latency and packet loss. It doesn’t highlight the problem itself but gives the user an alarming notice that there is a problem that needs to be resolved. To solve a troubleshooting problem, this is used as the very first attempt to resolve the issue.
The host is a very commonly used command. This can be used to find either the domain name associated with the IP address or vice-versa.
Ipconfig is commonly used as another troubleshooting tool to resolve the occurring issue. This command is used when the user requires to know the IP address of the host. That they are working on, this command gives a lot of essential information such as IPv4 or IPv6 address, DNS service, other addresses, the data showing the exact traffic flowing over the interface, and a long list of such information.
Netstat To troubleshoot any issue, the Netstat command can be used as a utility when it is suspected that system security is at risk or unknowingly, ports or hosts are open. For the servers that run their firewalls, in such a situation, this command can be used.
There is a longer list of the Linux network command, and to get it more clear in one’s memory, Linux network command cheat sheets can be used as it makes the user have a quick memory about the common and important commands when it is required the most. It makes the work easy and keeps the command handy for use.
Q.1 What commands will reset a network interface in Linux?
The commands to reset a network interface involves the given steps
ifdown First, this command is used to turn off the already running network interface.
Ifup Once, the previous command has stopped the already working network interface. This ‘ifup’ command is used to turn it on again, which will result in restarting the interface.
Ip/ipconfig Once the interface has been successfully restored. This command is used to get the IP address.
Q.2 How to pass windows commands over a network on Linux
Q.3 What are some common CLI commands that can be used to check network status and connectivity of Linux
1.nmcli tool One of the most commonly used tools to see network connectivity, to activate or deactivate, to create or edit, and everything related to network connection, this network manager command-line tool is used as one of the most common utility.
2.nslookup command This is the next useful tool used to get DNS (Domain name system) related details or are used to rectify issues related to DNS.
3.Tracert or Traceroute tracks and tells the IP address of all the routers that it pinged in between. This command is used to trace the pathway taken by the packet from the source to the point of destination.
4.tracepath This is a similar command as traceroute, used commonly to trace the destination’s path. A tool that shows the path to the network host discovering MTU along the way.
Q.4 What are the commands for disabling and then re-enabling a network card interface in Kali Linux?
To disable and re-enable a network card interface in Kali Linux;
First, you have to use the ‘ifconfig’ command to a few of your ports.
Once you have known the port name that turns up and that you need to use, let’s say we name it ‘x’ for now. To disable the network card interface, use the command line as ‘sudo ifconfig ‘x’ down.’
When it is disabled, to re-enable the port use the command as ‘sudo ifconfig ‘x’ up.
Linux has been a competent operating system. Linux network commands are all related to the long list of commands that the programmers use to resolve various virtual troubleshooting issues, monitor network connectivity, manage to route, and take care of everything associated with network commands in Linux.
As a beginner or a professional, anyone usually raises questions like, What commands will reset a network interface in Linux or about the most preferred chest sheet that usually helps in fast monitoring or troubleshooting problems occurring in Linux networking.
Every command varies according to usability. Some are used to disable or re-enable the network card interface, or some are used to check for the network connectivity. If quick in mind, these command lines can be equally used to resolve the most complicated issues related to computer networking.
