Net::Daemon dies with an error when I try to run my server as root: $ perl -Mblib -MNet::Daemon -we 'Net::Daemon->new({ user => "root", group => "root", pidfile => "none", localport => 1034 })->Bind' Using /home/test/.cpan/build/Net-Daemon-0.37/blib Cannot determine gid of root: at /home/test/.cpan/build/Net-Daemon-0.37/blib/lib/Net/ line 569. at /home/test/.cpan/build/Net-Daemon-0.37/blib/lib/Net/Daemon/ line 130. The test "if (my $gid = getgrnam($group))" needs to be changed to "if (defined(my $gid = getgrnam($group)))" to make it work when user or group is given by name and its ID is zero.

Thanks, patch applied in 0.38. (Although I still wonder why one should explicitly specify UID 0 ... :-)

This bug is years old. It has not been reported or commented upon since then, and the revision is now up to 0.41. I cannot help but think that the issue has been resolved. Revision 0.41 was just submitted today. If the issue has not been resolved, hopefully the CPAN testers will flag it.
