<div dir="ltr">Also, it could be a firewall issue. Some OS's block all ports by default for inbound connections.

</div><div><div>

<div>
<div>
<div dir="ltr">
<div>At work we had a Windows XP computer setup to collect lab results from Quest. 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. </div>
<div><br>
</div>
<div>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. </div>
<div><br>
</div>
<div>I am getting a "Could not connect. No connection could be made because the target machine actively refused it" error. </div>
<div><br>
</div>
<div>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. </div>
<div><br>
Any suggestions?</div>
