Re: [Nfdump-discuss] Update ASN in nfdump

[James D. <je...@on...>]

About a year ago, Tomas Podermanski had a post about his perl library that
provides some of this functionality with a great example script that you
might review (nf_asn_geo_update):

It's not quite what you asked but you could have it populate the fields at
file rotation. We used this for some time while dealing with errant data
that was being populated by the manufacturer we work with. The country code
population was rather unique and provided for some interesting (and quick)
analysis.
