I am having a similar problem under Windows XP and Perl 5.8.6: 
C:\>perl -de 1

Loading DB routines from perl5db.pl version 1.28
Editor support available.

Enter h or `h h' for help, or `perldoc perldebug' for more help.

main::(-e:1):   1
  DB<1> use Net::Ping;

  DB<2> $tcp = Net::Ping->new('tcp');

  DB<3> print +($tcp->ping('4.2.2.2') ? "Up\n" : "Down\n");
Up

  DB<4> $icmp = Net::Ping->new('icmp');
icmp socket error -  at (eval 11)[C:/Perl/lib/perl5db.pl:628] line 2

  DB<5> print "$]\n";
5.008006

  DB<6> q

[download]

The code in Ping.pm getting the error is: 

socket($self->{"fh"}, PF_INET, SOCK_RAW, $self->{"proto_num"}) ||
  croak("icmp socket error - $!");

[download]

Raw sockets can only be opened by those running with 'root' permission (easily verified on my Linux box). However, what's the equivalent under Windows? I have an alternate id that's a full administrator, but it fairs no better. The maddening thing is that this used to work for me, but with my brand-new laptop with WinXP - it's broken.

Does anyone have an idea how to allow a normal Windows user to open a raw socket so that icmp pings can work?

TIA
