Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

Oops ... still not quite time for a victory lap ... Some time ago, we worked out that I could run several awk commands like this concurrently in separate terminal windows: > time sudo nmap -sS -p3389 -T4 --host-timeout 300 --min-hostgroup 25 -iL Input-IPv4s.txt > nMap-IPv4s-to-HNs.txt and

Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

After composing yet another chapter in this treatise and then losing it after an errant pinkie brushed across the freeze-the-system key, I'm starting over to find a way of finishing the hostname-resolution process: There are three methods of resolving hostnames: 1. Magic Banana's technique

Backtracking to find a less error-prone script-creation process: Step (1): Apply Magic Banana's one-line processor to the single-column Hostname_List containing all the Webalizer records for a time period: tr -sc 0-9\\n ' ' < hostname_list | awk '{ k = 0; for (i = 0; k < 4 && ++i

Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

This may be on the right track, but has a syntax error when I try to process the three permutated IPv4 addresses: time tr -sc 0-9\\n ' ' < CPV-GB-OneCol0-6192019.txt | awk '{ k = 0; for (i = 0; k < 4 && ++i CPV-GB-TwoCol-OutputY.txt The awk command is intended to select the one

Magic Banana lamented: >The third column of "output-2-column-file.txt" cannot be computed from the input alone, as far as I understand. If it were mine to do as well as you can ... I'd reverse the octet order in the third column, look them both up with nMap or nslookup, and compare to the

Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

Magic Banana woke me up with: "Input excerpt and expected output..." OK. The beginning-5-col-file shows all five tab-separated fields. The output-2-column-file actually has an added third column listing the proper IPv4 addresses that resolve to the hostnames in the first column. You will see

Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

Armed with my new knowledge, I processed all 35,000 lines of the source file so as to separate one file with the original four-octet-containing hostnames and four additional columns each containing one of those four octets. That list of IPv4's is 3500 lines long, out of 14,000 hosts that were

Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

It turns out that nMap doesn't care which way the lookup process goes; I'm currently processing the entire file (35,000 lines) for one four-month data set, and the hostnames as well as the IPv4 addresses are being handled with the same output schemes. The actual separation process will

Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

Here's a sample of one online Webalizer file (stripped of reams of frequency and byte data) which is trivial to separate. Now imagine about half a million lines of such data in random order. I can strip out the hostnames by putting two identical target lists side-by-side in OpenOffice

Re: [Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

I went through the file HNs-nMap-LixedList.txt and resolved all the hostnames, mainly by inspection (two were based on ARPA naming and so had their octets arranged in backwards order), many with Google, usually the first item in the list, and one by truncating the prefix from q.jaso.ru to

[Trisquel-users] How can one capture the "Failed to resolve" output to console during an nMap scan ?

After removing the unconverted IPv4 addresses from the Webalizer statistics of a domain, there's a long list of PTR records and an occasional A record left behind. nMap has a useful script (--script asn-query) to perform lookups of the ASN, port status, CIDR block, country code, and even
