To change the language of the GUI, use the LANG environment variable: Please refer to Nmap installation howto Interface Start the interface It enables to use Nmap without fully knowing the syntax (sometimes complex). Nmap adds a versatile tool to any system administratorвЂ™s arsenal for debugging and locating security flaws.Zenmap is the GUI frontend of Nmap. You should now understand how ports work, and why it is important to know how they are used. This guide provided an overview of Nmap scanning and how you can use it for testing ports in Linux. Most ports under 1000 are dedicated and assigned to a specific service. If a service is running on a non-default port, it might be by design вЂ“ or it might suggest there is a security breach. The OS and Service scanning options are helpful for scanning a particular port or service to get more information. This means there is something strange going on, and should be investigated. For example, you may see a service running on an unusual port number. It is possible that during your scan, you may find unusual activity. It is also considered a bad practice to tie up a serverвЂ™s resources by using Nmap to run repeated scans on the same target. Often, port-scanning is seen as an aggressive method, or a prelude to a cyber attack. You should only use Nmap port scanning on servers that you own, or that you have permission to scan.

Use a firewall in conjunction with other network security tools and software to scan traffic on a particular port, and to watch for suspicious traffic. You can use firewall rules to allow some ports, but block others. Here is a brief list of standard ports and their designations:ДЄ Linux firewall can be configured to block all traffic on a particular port.ДЇor example, a firewall can be set to block Port 80, but users wonвЂ™t be able to load any website in that case. The more intense the testing, the longer the scan will take.

Replace the number 2 with a number from 0 (light testing) to 9 (run all probes). Use the вЂ“вЂ“version-intensity 2 option to specify the level of testing. Note: The вЂ“sV option can be tuned to be more or less aggressive in its scan. It can also be used to probe for the services that might be using different ports: nmap вЂ“sV 192.168.0.1 The nmap utility can be used to detect the operating system of a particular target: nmap вЂ“A 192.168.0.1 This option forces the test without waiting for a reply that may not be coming): nmap вЂ“Pn вЂ“F 192.168.0.1 (Host discovery uses ping, but many server firewalls do not respond to ping requests. Run a fast scan on the target system, but bypass host discovery. To instruct Nmap to scan UDP ports instead of TCP ports (the вЂ“p switch specifies ports 80, 130, and 255 in this example): nmap вЂ“sU вЂ“p 80,130,255 192.168.0.1 To perform the default SYN scan (it tests by performing only half of the TCP handshake): nmap вЂ“sS 192.168.0.1 To scan using TCP connect (it takes longer, but is more likely to connect): nmap вЂ“sT 192.168.0.1 To scan all ports (1 вЂ“ 65535): nmap вЂ“pвЂ“ 192.168.0.1 Other Types of Nmap Port ScansДifferent types of scans can be performed: Scan (Fast) the most common ports: nmap вЂ“F 192.168.0.1 Scan ports 1 through 200 on the target system: nmap вЂ“p 1-200 192.168.0.1 Scan port 80 on the target system: nmap вЂ“p 80 192.168.0.1

Nmap commands can be used to scan a single port or a series of ports:

You can use this to test your Nmap utility. Note: The developers at provide a test server that you can experiment on, located at.
