April 19, 2016 at 12:587 online scanners to search for open ports on the server
- Transfer
From the translator. Hi, today I want to publish a translation of the article with a list of services that will help find open ports on the servers. Hope this article is helpful.
If you host your web applications on an administered server or shared hosting, then you have nothing to worry about. However, for a virtual or dedicated server, you must consider all the security features of your server.
Having unnecessary ports open is a bad idea from which an attacker can benefit in many ways.
Below are the free online services that will help you find out if the ports are open so you can check and block them if they are not in use.
Note: if you run a port scanner for the DNS of your site, and it is located behind proxies such as CloudFlare or SUCURI, then it may not provide accurate information. Use the real server IP address.
MX Toolbox tries to check the 15 most commonly used ports with a timeout of 3 seconds and gives the results, which ones are open and which are not.
Pentest Tools checks open ports using NMAP on the target host. You can select the operating system definition and service version. He will give you the results for open ports and offer to save the scan details in PDF format.
This tool is a personal project of Javier Yanez, which allows you to scan ports for IPv4 and IPv6 addresses for free.
Scans one or a range of ports listened by the server with the specified IP. This is convenient if you only want to scan the selected ports.
Performs a quick scan of the six most common ports (FTP, SSH, SMTP, HTTP, HTTPS, RDP) with an NMAP port scanner.
Scan about a thousand frequently used ports using NMAP or specify your ports for your domain or IP.
Quickly scans some common ports, such as FTP, SMTP, DNS, Finger, POP3, SFTP, RPC, IRC, IMAP, VNC, etc. I hope the above tools help you find open ports on your domain or IP. Use a firewall to allow the use of the required ports and ignore the rest. You may also consider changing the default port for SSH, as shown here . PS All projects of the Hosting Cafe switched to work through the https protocol :
