How to find multiple words on one line in Notepad ++

Question

I have a 4 MB log file from the Windows XP firewall that I am trying to find lines that have both DROP and IP address and port number. My regex-fu is weak, and I guess this is the reason I'm fighting.

The words "DROP", "10.1.1.1" (for example) and "8801" must be found on the same line and can be distributed on the line and separated by one or more other words.

Any help (or suggestions of another method for this) is greatly appreciated.

Answer 1

The simplest solution should be:

DROP.*10.1.1.1.*8801 

Answer 2

It will be done in notepad ++

 DROP.*10\.1\.1\.1.*8001 

Or a simple regular expression for different IP addresses (since you do not need to check the IP address itself)

 DROP.*\d\.\d\.\d\.\d.*8801 

Answer 3

Notepad ++ RegEx does not seem to recognize curly braces that do not capture groups or \ b. The closest I could find is:
DROP\s.*[0-9]+[.][0-9]+[.][0-9]+[.][0-9]+.*\s[0-9]+ or
DROP\s\d+\.\d+\.\d+\.+\d+.*\s\d+

Answer 4

This question will help you solve a lot:

 DROP|\b(?:\d{1,3}\.){3}\d{1,3}\b|8801
