Doug Barton 2fadfa2cfb For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.

Sing is a little tool that sends ICMP packets fully customized from command
line. The main purpose is to replace/complement the niceful ping command
with certain enhancements as:
- Send fragmented packets (Linux and BSD).
- Send monster packets > 65534 (Linux and BSD).
- Send/read spoofed packets.
- Send many ICMP Information types in addition to the ECHO REQUEST type sent
by default as Address Mask Request, Timestamp, Information Request, Router
Solicitation and Router Advertisement.
- Send many ICMP error types: Redirect, Source Quench, Time Exceeded,
Destination Unreach and Parameter Problem.
- Send to host with Loose or Strict Source Routing.
- Use little fingerprinting techniques to discover Windows or Solaris boxes.
- Send ICMP packets emulating certain OS: Cisco, Solaris, Linux, Shiva,
Unix and Windows at the moment.
