in reply to IO::Socket:SSL and Net::Server STDOUT redirection

McA got to the heart of the problem already, although I'm not sure if the same solution can be applied with Net::Server. It uses Tie::Handle to capture STDOUT, which obviously wont be respected by any forked process. However, you could use IPC::Run to capture the output instead. The following works:

package NetServer; use base qw(Net::Server::Fork); use IPC::Run; sub SSL_key_file { "key.pem" } sub SSL_cert_file { "cert.pem" } sub process_request { my $command = [ 'echo', '==== System Command Successful' ]; IPC::Run::run($command, '>', sub { print shift }); } NetServer->run(proto => 'ssleay', port=>12345);

And actually in the simple case, IPC::Run doesn't buy you much over just:

print qx( /usr/bin/echo ==== System Command Successful );

But to be clear, the IPC::Run version is better when executing a long running child, since it will asynchronously capture and forward output. The "qx" version waits until the child completes before forwarding the output.

    This worked pretty good too. Thank you!

    The distinction between qx() and the IPC::Run version was also nicely explained. I appreciate it!
