I recently moved my PRTG installation from one server to another, using the instructions found here:
Most things worked straight away, but I'm having trouble restoring the connection with a Powerware UPS, which is also the only device that uses SNMP v1 (all others use v3).
I can ping the device from the PRTG server, and I receive SNMP traps from it, and SNMP traffic to other devices on the same network can traverse the firewall(s), but on this one device I get SNMP error # -2003 in both PRTG and the SNMP Tester software.
I thought maybe it was because I was missing the Powerware MIBs on the new server, but even after re-importing them with the MIB Importer tool I still get the same error.
I have also tried re-creating the device, but when trying to add the Powerware SNMP library sensor(s) it stays on Preparing sensor settings... for a long time and then gives the same error (2003).
I've tried for hours to figure out what may be causing this and I'm not getting anywhere - any suggestions what else to try?
