smitz has asked for the wisdom of the Perl Monks concerning the following question:

Darndest thing ever, fellow monks. I was playing with the perl -d test.pl debugger, and it failed with an odd looking error about connecting to localhost. Of course, I assumed it was my test.pl script, but it aint. Join me below the readmore tag for hot code action.
C:\perl -v This is perl, v5.8.0 built for MSWin32-x86-multi-thread C:\>more test.pl #!perl use strict; my $var = 'Beard\n'; print $var; C:\>perl -d test.pl Unable to connect to remote host: 127.0.0.1:2000 Compilation failed in require. main::BEGIN() called at C:/Perl/lib/perl5db.pl line 0 eval {...} called at C:/Perl/lib/perl5db.pl line 0 BEGIN failed--compilation aborted.
Thanks for any input, I really dont even know where to begin (ha!) on this one. Of course the test.pl is irrelevant, but why on earth is the debugger attempting a connection?

    Looking at the code, it seems that the only way this could happend is if you set the option RemotePort. It looks for options in a couple of places. First it looks for a file called (on windows) "perldb.ini" in the current directory, your home directory (if $ENV{HOME} is defined), or $ENV{LOGDIR} (if defined).

    It then looks for an environment variable called PERLDB_OPTS.

    Hope that helps.

    It looks like you have the "remoteport=localhost:nnn" set in an environment variable called PERLDB_OPTS or possible a config file (called ./.perldb or ~/.perldb) containing parse_options("remoteport=localhost:nnn").

    See perldebug and/or

    perl -de1 h O ... RemotePort Remote hostname:port for remote debugging ...

    For (a little) more information.

      Folks who try Active States Dev Kit end up with this error when the demo runs out because the de-installer doesn't clean this Environment Variable up. So, you will have to do it yourself. You can do it from the system properties on the environment variables tab if you are on 2K/XP.
      He! perl -del dies with the same message, and I definately dont have an env. var. like that set, I've listed all of them below.
      Thanks for the suggestions though, keep them coming :-)

      Update: In fact, I do have that Env Var set. Wake up, smitz

    And I have searched all my drives for a file called perldb.ini, and found nothing. The thing is, this isn't the first time I've used the debugger, and it always worked fine. Grrrrr
