<div><p><span class="keyword">i5/OS™</span> PASE is
generally compatible with AIX<sup>®</sup> and Linux<sup>®</sup> in sockets communications.</p>
<p><span class="keyword">i5/OS</span> PASE
supports the same syntax as AIX for sockets communications. This cannot match other
operating systems, such as Linux, in every detail.</p>
<p><span class="keyword">i5/OS</span> PASE sockets support
is comparable to the AIX implementation of sockets, but <span class="keyword">i5/OS</span> PASE
uses the <span class="keyword">i5/OS</span> implementation
of sockets (instead of the AIX kernel implementation of sockets), and this forces
some minor differences from AIX behavior.</p>
<p>The <span class="keyword">i5/OS</span> implementation
of sockets supports both UNIX<sup>®</sup> 98 and Berkeley Software Distributions (BSD) sockets.
In most cases, <span class="keyword">i5/OS</span> PASE
resolves differences in these styles by adopting the behavior of the AIX implementation.</p>
<p>In addition, the user profile for a running application must have the *IOSYSCFG
special authority to specify the level parameter as IPPROTO_IP and the option_value
parameter as IP_OPTIONS on socket APIs.</p>
