<div dir="ltr"><div>Specify the ups.conf data points including the IP address/hostname of the UPS as "port", the community (for SNMPv1/2) or real auth (v3), and optionally the MIB you prefer (by default the driver auto-picks known vendor extended MIBs until it tries the IETF standard MIB as the final fallback). <br></div><div><br></div><div>Make sure firewalls permit stuff (with SNMP usually being UDP so there may be no session to auto-permit replies based on your outgoing requests - depends on firewall engine). Likewise, wrong auth and hence no reply is indistinguishable from unavailable server since there is no dialogue to tear down.<br></div><div><br></div><div>
<div>Note that SNMPv3 relies on SSL capabilities and that depends on the library versions NUT was built against. There were enhancements to that after NUT v2.7.4 (which is old, but still is the version which some distros package), so some woes may be due to that.<br></div><div><br></div>

<div>Does nut-scanner discover the UPS?</div><div><br></div>
Otherwise, the usual questions: which UPS, which NUT version, what config you try, what error messages say, did you try higher debug verbosity?..</div><div></div><br><div>Hope this helps,</div><div>Jim Klimov</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Apr 12, 2023 at 2:43 AM Prometheus via Nut-upsuser <<a href="mailto:nut-upsuser@alioth-lists.debian.net">nut-upsuser@alioth-lists.debian.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">I'm having trouble using the documentation to install the SNMP driver to use in my UPS how do I install the driver to actually get it to work?<br></div>
