This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --DLNf3sOgbH8ADJnpmfNiAMVPtolg7aqeK Content-Type: text/plain; charset=windows-1252 Content-Transfer-Encoding: quoted-printable Hi, I use FreeBSD 10.0-BETA3 amd64, upgraded from 9.2-RELEASE with freebsd-update. I was capturing with tcpdump and doing some grep on it: # tcpdump -li nfe0 port 53 | grep Refused > capture.txt I was surprised that capture.txt is totally empty. If I don't redirect the output, then it writes what I need on stdout. It's very very strange=85 --=20 Florent Peterschmitt | Please: florent@peterschmitt.fr | * Avoid HTML/RTF in E-mail. +33 (0)6 64 33 97 92 | * Send PDF for documents. http://florent.peterschmitt.fr | * Trim your quotations.
