Add Pattern to Nmap boefje to match a range of numbers, eg 0 to 65000 are not overly easy to do, but here's a try:

          The revisit this. Patterns that match a range of numbers, eg 0 to 65000 are not overly easy to do, but here's a try:

(([1-9][0-9]{0,3}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-4]),)*?(([1-9][0-9]{0,3}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-4])-)?([1-9][0-9]{0,3}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-5])

This will match the following:

• 1
• 1,2
• 1-65000
• 1,2,100-200
• 65534-65535

Rules:

• The number of single ports is unlimited, the number of range groups is unlimited, but expected to come after the single ports.
• Range groups are intended to be separated by a dash
• No spaces / other chars are allowed.
• Port numbers (single or in range) are limited from 1 to 65535
• A small number is allowed as the second argument in a range, this is not easily fixed in the regex, but we might be able to flip them round in the boefje code.
