Network troubleshooting means fixing the issue happening in the computer networks by pinpointing, determining, and sorting out the root cause.To know more, you can also visit this recommended site. It is a mechanical process carried out by network engineers; it can be manual and automated.
Five network troubleshooting tools are –
The ping is the most popular and broadly used network troubleshooting tool for the primary network issue- identification process. The ping form network troubleshooting as its use.
It supplies details on the available connectivity connecting the host requesting the connection and the host, the terminus through a test.
The testing procedure takes place by using ICMP (Internet control message protocol). This protocol gives the provision to dispatch an echo packet to the terminus host and hear its feedback.
If the demanding host can get the terminus host’s feedback, the terminus host is reachable. This shapes a primary picture of the situation and certifies if the networking problem is happening or not.
2. Traceroute/ Tracer
After going through the ping tool to know the basic connectivity outline, we need tools to assemble more certain factors and network information about the track and route of the terminus host and the feedback timing of median and terminus hosts.
For this purpose, traceroute and tracer tools are used by network professionals.
In networking, a path that leads to the terminus comprises many leaps or ends. Each leap is used for scattering and operating ahead of the packets.
The traceroute tool detects and gives information on each leap to a terminus. This is something that one cannot do only with the ping tool.
Traceroute and Tracers are used to detect and spot network issues that proceed far away from the local network.
They give all the essential details about the path, including all those devices that take your packet to the terminus. This tool provides IPs, hostnames, and feedback times of each leap.
There is a censorious step involved while network troubleshooting, which is to recognize the particular IP configuration of the pretentious hosts. A unique tool is used to carry out this process: IPCONFIG.
It gives all present TCP/IP layout information on all networks which are connected presently.
For instance, the network in use avails DHCP server to give IPs to all the hosts. In such a case, IP layout is an essential procedure while troubleshooting.
It can also be utilized if the IPs are given statically by the network because then there is a chance that there may be a swap in the IP address.
All the information related to network adapters like Default gateway, IPv4 and IPv6 addresses, and Subnet mask, is provided by Ipconfig.
4. Net stat
Another site needed to identify a network issue is the present circumstance of active network connections on a host.
It is vital information that the IP engineers need to observe the root cause for numerous network troubleshooting reasons. For example, to examine and confirm the position of a listening port on a host and remote hosts are attached to a local host on a particular port.
The net stat is small for network data. It gives you complete information on the current network connections on the computer.
Net stat is vital for troubleshooting when we want to know about the open ports and remote servers that are presently creating a connection to our computer with their ports.
5. NSLookup (Name server lookup)
It helps us solve some of the most basic network troubleshooting problems related to DNS addresses.
Users use a DNS address to avail themselves of domain names and IP addresses. Internet or website functionality is hampered for use or cracked when this function is damaged or defective.
This command is used to regulate if the DNS server is solving names. It is used to discover and shape the specific IP address or multiple addresses attached to the domain name. There is some DNS problem if it cannot translate a name or fails to grasp and give information.
Using a simple finding algorithm, the NSLookup tool can discover particular DNS servers and figure out an issue with the default DNS addresses built on a host server. The PING and TRACERT can resolve the domain name to an IP name. Information is directly taken from the host’s built DNS server by NSLookup.
All the tools mentioned above are within everyone’s reach. These tools remarkably remove troubleshooting time, and they are easy and free to use.
