Either ssh with keys, NRPE with ‘mrtg-nrpe’, or something similar. This sort of information is not normally in SNMP, though you could write your plugin as a ucd-snmpd extension to make it so, though this is getting into a bit advanced coding. I don’t think anyone else has done this previously, though there was an ipchains extension for ucd-snmpd once.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Steve<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Steve Shipway<o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>s.shipway@auckland.ac.nz<o:p></o:p></span></p><div><div><p class=MsoNormal><o:p> </o:p></p></div></div></div></body></html>
