Seems an ideal application for threads. Something like this should get you started. You'll need to fill in the blanks.

#! perl -slw use strict; use threads; use threads::shared; use Thread::Queue; my $logSem :shared; sub LOG { lock $logSem; print @_, "\n"; } sub worker { my( $Q ) = @_; require Net::Telnet; my $tn = Net::Telnet->new( Timeout => 10, ... ); while( my $apip = $Q->dequeue ) { if( $tn->open( $apip ) ) { LOG( "$apip OK" ); $tn->close; } else { LOG( "$apip: Failed" ); } } } our $W ||= 15; ## Default to 15 threads; Don't get carried away! ## Create a Q to supply workers with work my $Q = new Threads::Queue; ## Create the worker threads, passing the Q handle my @workers = map threads->create( \&worker, $Q ), 1 .. $W; ## Push the IPs onto the queue for my $foo ( %controllers ) { ## ???keys values??? for( @{ $controllers{ $foo }{ access_points } } ) { $Q->enqueue( $_ ); } } ## Terminate worker loops $Q->enqueue( (undef) x $W ); ## Wait for the workers and join them when they're done $_->join for @workers;

If your serial code takes 15 minutes, this should reduce it to ~1 minute. But don't get carried away increasing the number of threads, as there are diminishing returns.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
