<h2>Debugging IP over SNA Configurations</h2>
|
|
|
|
<p>Two commands can be helpful in debugging IP over SNA configurations:</p>
|
|
|
|
<ul>
|
|
<li>The Start Mode (STRMOD) CL command can help you determine if your SNA
|
|
configuration is correct. As input to the STRMOD command, you need the remote
|
|
location name. You can determine the remote location name from the destination
|
|
IP address by using the Convert IP over SNA Interface (CVTIPSIFC) command. The
|
|
message you receive when STRMOD completes tells you whether it was
|
|
successful.<br>
|
|
<br>
|
|
</li>
|
|
|
|
<li>The TCP/IP FTP command can help you determine if your AnyNet configuration
|
|
is correct. If you get the <em>User</em> prompt, the AnyNet configuration is
|
|
correct.
|
|
|
|
<p><strong>Note:</strong> When FTP fails, it does not give a detailed reason
|
|
for the failure. To get a detailed reason, you should run a sockets program
|
|
that reports the value for <em>errno</em> when the failure occurs.</p>
|
|
</li>
|
|
</ul>
