<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""> SYNOPSIS:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">On a machine with more than 63 (possibly 62) IP Addresses (not sure if per-interface or globally) my TAO client and tao_cosnaming.exe crash.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""> DESCRIPTION:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">On machines with quite a few IP Addresses (in this case static IPs all assigned to the same interface), tao_cosnaming.exe will throw an exception and quit at startup. While trying
to narrow down the cause, our tao test client (normally very reliable) will throw an INTERNAL exception when calling resolve_initial_references(“RootPOA”). TAO servers can avoid this issue by specifying a particular IP Address with –ORBListenEndpoints.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">The NamingViewer.exe runs correctly even when there are > 63 IP addresses present in the system. The NamingViewer does call resolve_initial_references(“NameService”), but does NOT
appear to call resolve_initial_references(“RootPOA”).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""> REPEAT BY:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">In an elevated command prompt, create a number of IP Addresses on an interface. First line below is explanation—replace items in braces. Second line is an example of how to create
111 addresses from 192.168.30.10->120. Note that if you have your {InterfaceName} set to DHCP, the first time you run this, you will reset the adapter to the static IP address you define. So either start with a static IP address already set, or run netsh
first with an IP address that is on your network. I used an IP addresses (192.168.30/24) outside our normal subnet to avoid collisions.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""> C:> REM for /L %A IN ({start},1,{end}) DO netsh interface ip add address “{InterfaceName}” 192.168.30.%A {mask}<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""> C:> for /L %A IN (10,1,120) DO netsh interface ip add address “Local Area Connection” 192.168.30.%A 255.255.255.0<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">(Also note, on Windows 7, the mouse may be jerky initially after this command, but it settled down for me after a while. Windows Server 2012 had no discernable discomfort with this.)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">Then run tao_cosnaming.exe.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">Error including “(endpoint initialization failure in Acceptor Registry; unspecified errno)” is displayed.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">I tested this with TAO 6.3.3 on Windows 7. We have older version of TAO (1.4.1) also running on Windows 7 and Windows Server 2012 R2 where naming_server and the call to resolve_initial_references(“RootPOA”)
also suffers from same behavior.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""> SAMPLE FIX/WORKAROUND:<o:p></o:p></span></p>

</span></span></span><![endif]><span style="font-size:10.0pt;font-family:"Courier New"">Reduce the number of IP addresses in the system (might be a per-interface limit).<o:p></o:p></span></p>
<p class="MsoNormal" style="text-indent:.5in"><span style="font-size:10.0pt;font-family:"Courier New"">C:> for /L %A IN (70,1,120) DO netsh interface ip delete address “Local Area Connection” 192.168.30.%A<o:p></o:p></span></p>
<p class="MsoNormal" style="text-indent:.5in"><span style="font-size:10.0pt;font-family:"Courier New"">This leaves only addresses from 192.168.30.10-69 on your system. Now things work again.<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="font-size:10.0pt;font-family:"Courier New""><span style="mso-list:Ignore">B)<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span style="font-size:10.0pt;font-family:"Courier New"">For TAO servers AND TAO CLIENTS THAT CALL resolve_initial_references(“RootPOA”), limit the addresses they listen on with –ORBListenEndpoints
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">That very last part above is the key workaround. A client that calls resolve_initial_references(“RootPOA”) will receive an INTERNAL exception unless the number of interfaces to listen
on was restricted by passing something like –ORBListenEndpoints iiop://192.168.3.239, which limits whatever happens in resolve_initial_references (“RootPOA”) to fewer IP addresses and prevents the INTERNAL exception.<o:p></o:p></span></p>
