Has anyone seen this before? I'm almost 100% certain I tested this nut correctly detected OB LB in the past, but when I happened to look at it today, I see it refusing to work -- apparently because the NUT client knows how to ask for RFC1628 OIDs, but not what to do with the responses. WTF! # /lib/nut/snmp-ups -a GE-EP3000 -DDDDDDDDD Network UPS Tools - Generic SNMP UPS driver 0.47 (2.4.3) 0.000000 debug level is '9' 0.001846 SNMP UPS driver : entering upsdrv_initups() 0.001860 SNMP UPS driver : entering nut_snmp_init(snmp-ups, ups, v1, public) 0.030096 SNMP UPS driver : entering load_mib2nut(ietf) 0.030123 load_mib2nut: trying ietf mib 0.030132 nut_snmp_get(1.3.6.1.2.1.33.1.1.1.0) 0.032006 [GE-EP3000] unhandled ASN 0x5 recieved from 1.3.6.1.2.1.33.1.1.1.0 0.032019 Unknown mibs value: ietf If I leave out mibs=ietf, I get the same, only it tries other MIBs first, and the last line changes to 0.051158 No supported device detected Here's my config, which I'm almost certain worked before. AFAIK nobody has fiddled with the UPS settings, either. Is the problem in nut or in the UPS? (Looks like nut to me.) Has anybody seen this before? A naïve "apt-get --reinstall install nut nut-snmp" didn't help.
