SNMPd: Cannot open /proc/bus/pci

问题 I cross-compiled NET-SNMP 5.7.1 from sources to a PowerPC using ELDK-3.1. When I try to load the snmpd daemon in my embedded board, I see the message: # snmpd -f -Lo pcilib: Cannot open /proc/bus/pci pcilib: Cannot find any working access method. Of course my PPC board has no PCI, and I wonder why is netsnmp looking for it. In more than one place I see this same message (sourceforge, mail-archive, google-groups), but ir has no answer at all. Another variant, with a little but unhelpful

What is the correct encoding for SNMP type Unsigned32?

由 ∥☆過路亽．° 提交于 2020-01-03 14:05:09
问题 I'm writing an SNMP agent and the MIB definition includes an OID of type Unsigned32. The Unix implementation of the agent uses Net-SNMP and sets the OID as type ASN_UNSIGNED, since it doesn't have an ASN_UNSIGNED32. When I look at the GET response with Wireshark, it decodes it as a "Gauge32" value. That makes sense at first sight, because according to RFC 1902 Unsigned32 and Gauge32 are the same. The Windows implementation is based on Windows' SnmpAPI.lib and sets the OID as ASN_UNSIGNED32

Network discovery using broadcast snmp requests

问题 I want to discover the printers in my sub-net. Can I do that using net-snmp as mentioned in this following link- https://sourceforge.net/p/net-snmp/bugs/2336/ But it doesn't seem to work?
