That data was parsed and transferred to our mysql database (on a CentOS server) using Net::HL7::Connection. Recently we had to upgrade to Windows 7 for the capturing computer. So I'm using Windows 7 to collect blood work data from Quest. The scripts that were on the XP machine seem to work pretty well on the 7 box too, so I am able to get the data parsed and ready for transport to my mysql database server, but it doesn't send. I am getting a "Could not connect. No connection could be made because the target machine actively refused it" error. Net::HL7::Connection takes a host and port but no password or anything. I figure I'm supposed to open a port on the db server to allow this incoming connection, but I'm having trouble figuring that part out. I don't know where to look on the centos server to see if a port is open for the other xp computer, what file to edit... etc. Any suggestions?

Additionally, you can `grep` that output for the port you're trying to connect on to see if it's open, instead of parsing the whole output, *e.g.*, `netstat -len | grep :12345` (not 12345, natch, just whatever the port is).

Message-ID: Also, it could be a firewall issue. Some OS's block all ports by default for inbound connections. I don't know the correct invocation on centos to see what the firewall settings are, but if centos uses ufw. See if you can do a: sudo ufw status if you see it enabled, do a sudo ufw disable and then see if you can connect in... Obviously, the correct solution then is to figure out what ports the application is using and then enable those in the firewall, and re-enable the firewall if this is the case...

The client side script should be specifying the port it wants to connect to. You can check the client script for the port it wants to open with the output of the netstat command to see if that port is indeed open.
