<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:black">Remember in UDP-land checking if a port is open is a bit different. Since there are no nice things like SYNs and ACKs.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:black">You could use another plugin (e.g. search check_udp_port on Nagios exchange - that uses nmap to check it, which checks for ICMP port unreachables).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:black">Or find some string to use (use tcpdump, netcat etc), but you may be falling down a rabbit hole.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:black">Even better, use a check_radius plugin? That talks Radius and then you don’t need to worry about anything
