• Script to test the state of certain ports on your firewall from the outside

  Nmap online : an online version of the nmap utility. You can query any website or IP address but only a small number of nmap features are available. You may need to create a free account. The port scan looks at TCP ports FTP(21), SSH(22), SMTP(25), HTTP(80), POP(110), IMAP(143), HTTPS(443) and SMB(445). The Fast scan option scans the most popular 100 ports. Source: 12 months ago

• Dedicated Server Query

  (*)For Linux you just install it. If you run BSD, you should not be asking these questions, but telling us how to do it. :-D If you do not have access to a remote server, you can use e.g. https://nmap.online/ or search for "nmap online" and find one that you like that has no ads or anything else. Please ONLY run them on your own domain or IP address you currently have. Otherwise you will most likely violate your... Source: about 2 years ago

• check open ports to the internet with threads

  Typically you would want to use a tool like nmap for this, and one of the first results in a web search for "nmap as a service" is https://nmap.online/ which has a free and two paid tiers. Source: over 2 years ago

• What You Get After Running an SSH Honeypot for 30 Days

  A lot of these seem to use zmap (https://github.com/zmap/zmap) for the initial scan. Often with default parameters such as zmap setting ip id to 54321, having tcp initial window at 65535, having no SACK bit set and masscan with no SACK bit either, tcp initial window at 1024, tcp maximum segment size 1460 (which is strange to put below initial window size!), (older versions having fixed src port 61000 or 60000 from... - Source: Hacker News / 13 days ago

• Mass Scanning

  Can I get banned for mass scanning with https://github.com/robertdavidgraham/masscan or does it slow down any other vms from other persons? Source: about 1 year ago

• Has anyone ever had their homelab or network hacked? What happened?

  Nope, this doesn't work any more. Shodan checks all ports (so any attackers using data from Shodan already know which ports you have open), and tools like masscan (https://github.com/robertdavidgraham/masscan) let you portscan the entire IPv4 address space in less than 10 minutes.

• Private server intruded

  The discord user at the time used the tool "Masscan" to scan every 25565 port on the internet, he claims he was able to get the entire internet scanned in just a few minutes with a 512MB buyvm slice. Source: about 1 year ago

• My home server is frustrating me. Please help me, home server wizards.

  Changing the default port does nothing for security. It only prevents some basic brute force or default password scripts. Anyone is able to scan for it in no time anyway (https://github.com/robertdavidgraham/masscan). Source: about 1 year ago
