RE: [Hardhats-members] CPRS errors.

You could also just use a static on the internal network.  The key to some security outside your firewall is setting up the DMZ or port forwarding to only allow access to a list of external IPs.  Not many SOHO router/gateway/firewalls allow this.  But if you have a cheap 486/Pentium with two NICs, you can setup a linux firewall for just that reason.  (That’s what my good old K6-2 266 is doing – old skool…)

Some of the newer routers have a feature to let you define a mapping of the MAC address to a fixed IP.  This way, your router will assign a known IP when your computer connects to the router, without you having to set the computer up for static IP.  I use this feature to guarantee the IP that my printer, server, etc. are assigned.

You might have a problem if your computer gets a new
IP address from the router every time it boots up
(i.e. dynamic IP addressing), as you would have to
change the IP address of the DMZ computer each time.

I think I can guess how you are set up.  The only
way to access a VistA server 
over the Internet that I know of is if it is outside
the fire wall.  When you 
have your router connected instead of connecting
directly to your modem, you 
are inside a firewall and do not have a routable IP.
 Most routers have a 
setting to allow you to put your individual computer
outside of the firewall.  
find out your computers IP, if it is a Linux machine
use /sbin/ifconfig and 
if a Windows machine use Strart- Run-CMD-IPconfig
and find your IP, something 
like 192.168.0.101 and then configure your router to
put that outside of the 
firewall.  Hopefully, the individual computer has a
software firewall 
installed that you can configure to have an opening
only for CPRS so that 
your computer is not vulnerable to attack.

Hi, I am new to hardhats, and just learning VistA
      



software, although I have
    



been programming in M for quite a while.
 
My question has to due with CPRS and Delphi
      



errors.  I am working on VistA
    



over an internet connection.  I am encountering a
      



couple of problems.
    



1.) I can access CPRS as long as my router is
      



disconnected, but when my
    



router (netgear wireless G) is connected I get a
      



timeout error
    



(WSAETIMEDOUT) and don't even get connected to
      



enter an access/verification
    



code.  Is there some security setting that
      



interferes with CPRS?  My router
    



currently has the following protocols: NAT, SPI,
      



DoS, IDS, WEP encryption
    



and some other wireless security.
 
2.)  I get an error trying to access some
      



templates.  When I get into CPRS
    



and click on the notes tab and then the templates
      



section.  When I click on
    



some templates an error comes up and my window is
      



closed.  Following is the
    



error message:  Error encountered.  Function was:
      



recv  Error was: 10107 
    



and when I hit OK button I get the following error
      



Error encountered. 
    



Function was: recv Error was: 6.  Sometimes I get
      



the message invalid
    



pointer error.
 
Thank you for your help.
