Re: Assumptions needed to get the same tcpdump

[Hannes Gredler <hannes () juniper net>]

if your DNS is configured correct on both systems and you don't do any
site local private adressing then you should get the identical output
on both systems - if you specifiy the -n flag then tcpdump does not attempt
to resolve names, you should be fine i.e. identical output irrespective
how broken your DNS is.
