Re: [Hardhats-members] CPRS access from outside network

[Mark Street, D.C.]

netstat revealed that GT.M is listening on all interfaces.  *.9200

I have made note a some type of log file found in vista's home dir that
seem related to tcp connections.

The files have the name - XWBTCPC.mjo, XWBTCPC.mje and XWBTCPL.mjo

The latter seems like it keeps a running log, the former .mjo file seems
to log per attempt.

The contents of the file is;

HOME DEVICE DOES NOT EXIST IN THE DEVICE FILE
PLEASE CONTACT YOUR SYSTEM MANAGER!

Now, I know I have some issues with keys and locked menu items that I have
to clear up still.  I am sure I have some work to do with DUZ levels to
get this cleared up.

Thanks for the input!

 I believe GT.M listens on the first interface, whichever that happens
 to be.  Something like netstat should tell you once you open a listener.

 After configuration with GTM on my internal network I was able to

 At my work location after I set the server location and try to fire up
 CPRS it hangs without a login prompt.  I have a hole punched in my
 firewall to allow access from my work location on the outside interface
 on
 my server.

 I was wondering, when I startup a TCP listener in gtm, does it listen on
 all interfaces or just internal/private?

Re: [Hardhats-members] CPRS access from outside network

Thanks for the reply Nancy.  At this point this is a testing environment
for me.  I just want to get it to work.  I promise I will button it up
tight, in the meantime this is the only way I can test and configure from
a remote location.

 The connection between CPRS and the server is not secure unless you have
 done
 something to secure it.  Also, the server is set to a port, say 9200 and
 the
 client will seek the server on that port but the reply will be on a random
 port specified by the client, which is problematic unless they are on the
 same network likely inside the firewall with both client and server having
 a
 trusted relationship.

 Kevin tried to change the code to fix it to not reply on a random port.  I
 used his changes on my system and it has not worked.

 The latest release of VistA from February includes CPRSChart and server
 with
 patches that allow for the use of a single port but it is not secure.  At
 least you should be able to connect through a firewall, but you may not
 want
 to do it until the connection is secured by port forwarding or some form
 of
 VPN.  Meanwhile, I am hoping to get some help finding out where we I have
 gone wrong in trying to effect a solution with older versions of CPRS.  I
 would like to be able to do it with the CPRS used with the VA Demo.
