Ok, I cleaned stuff up a bit and reconfigured everything from scratch. I am
now able to get the snmpd master agent and subagent running on our hardware
box. Does the following "netstat" output seem reasonable?
Here is "netstat -an" output after starting the master agent on port 705 only:
# netstat -an

Now I decided to Telnet into our hardware box to perform some SNMP queries.
I executed the following master agent SNMP commands successfully:
/usr/local/bin/snmptranslate .1.3.6.1.2.1.1.3.0
/usr/local/bin/snmptranslate .1.3.6.1.2.1.1.3
/usr/local/bin/snmptranslate -On SNMPv2-MIB::sysUpTime.0
When I tried to issue some subagent-specific SNMP requests I got errors:
1) /usr/local/bin/snmpwalk -v1 -c mycommunity_ro ocStbHostAVInterfaceTable
getaddrinfo: ocStbHostAVInterfaceTable Name or service not known
snmpwalk: Unknown host (ocStbHostAVInterfaceTable) (No such file or
directory)
2) /usr/local/bin/snmpget -v 1 -c mycommunity_ro localhost
ocStbHostAVInterfaceType.1
getaddrinfo: localhost Name or service not known
snmpget: Unknown host (localhost) (No such file or directory)
3) /usr/local/bin/snmpget -v 1 -c mycommunity_ro localhost:705
ocStbHostAVInterfaceType.1
getaddrinfo: localhost Name or service not known
snmpget: Unknown host (localhost:705) (No such file or directory)
Any ideas why my subagent can not process these SNMP requests?
My snmpd.conf file contents are:
master agentx
agentxsocket localhost:705
rocommunity mycommunity_ro
My snmp.conf file contents are:
mibdirs +/usr/local/share/snmp/mibs
mibs +OC-STB-HOST-MIB:DOCS-IF-MIB:CLAB-DEF-MIB:DOCS-IETF-BPI2-MIB

And does the master agent open this socket?
If you run "netstat -an" (or equivalent) on the box,
can you see anything listening on port 705?
