( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I'm trying to open a socket to a service, send a message and receive a response. With the following code, I can do just that:
my $sock = IO::Socket::INET->new( PeerAddr => '10.0.0.1', PeerPort => '22222', Proto => 'tcp', ); print "Connection to 22010 is open\n" if $sock->connected(); my $buf; $sock->send( $msg ); $sock->recv( $buf, 200 ); print "Message: $msg\n"; print "Response: $buf\n"; $sock->close();
The trouble is that if the service is not functioning properly it does not respond, and so the call to recv hangs. It's okay if the server doesn't respond (that's kind of the point of this little smoke test), but I need to just get an empty response and move on...

Thoughts?

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
