Hi,all
I'm trying to extend snmpd agent using net-snmp5.4.1 and porting it to PPC
platform. Firstly I test it in my redhat 9 linux platform. I modified
default_modules.h in directory INSTALL_PATH/agent/mibgroup to include extending
MIB objects such as scalar_int, watched, data_set etc. that defined in
NET-SNMP-EXAMPLES-MIB.txt. then compile and install it. The modified
default_modules.h is as follows(abbreviated):
......
#else /* !NETSNMP_MINI_AGENT == the full shabang */
config_require(mibII)
config_require(ucd_snmp)
config_require(notification)
config_require(notification-log-mib)
config_require(target)
config_require(agent_mibs)
config_require(agentx)
config_require(disman/event)
config_require(disman/schedule)
config_require(utilities)
config_require(examples)
/* default MIBs to auto-include for parsing */
/* NOTE: we consider these MIBs users will likely want to load by
default, even if they're not supporting it in the agent (ie, the
command line tools need to load them anyway) */
config_add_mib(IP-MIB)
config_add_mib(IF-MIB)
config_add_mib(TCP-MIB)
config_add_mib(UDP-MIB)
config_add_mib(HOST-RESOURCES-MIB)
config_add_mib(SNMPv2-MIB)
config_add_mib(RFC1213-MIB)
config_add_mib(NOTIFICATION-LOG-MIB)
config_add_mib(DISMAN-EVENT-MIB)
config_add_mib(DISMAN-SCHEDULE-MIB)
config_add_mib(NET-SNMP-EXAMPLES-MIB)
......
The modified examples.h in direcotry INSTALL_PATH/agent/mibgroup is as
follows(abbreviated):
config_require(examples/scalar_int)
config_require(examples/watched)
config_require(examples/data_set)
config_require(examples/delayed_instance)
config_require(examples/netSnmpHostsTable)
when I operated on these extending objects using snmpget or snmpwalk command,it
return the correct results.
On my redhat 9 linux platform, the output is :
[r...@virtual-linux net-snmp-5.4.1]# snmpd -f -Le -d &
[1] 11498
[r...@virtual-linux net-snmp-5.4.1]# netsnmp_assert !"registration !=

netsnmp_assert !"registration != duplicate" failed agent_registry.c:535
netsnmp_subtree_load()
netsnmp_assert !"registration != duplicate" failed agent_registry.c:535

NET-SNMP version 5.4.1
[r...@virtual-linux net-snmp-5.4.1]# snmpget -c private localhost

Then I port it to my PPC platform and my config file is as follows:
./configure --build=i386-linux --host=powerpc-linux --with-gnu-ld
--prefix=/mnt/nfs/usr/local/net-snmp --with-default-snmp-version="2"
--with-logfile="/mnt/nfs/var/log/snmpd.log"
--with-persistent-directory="/mnt/nfs/var/net-snmp" CC=ppc_82xx-gcc
LDFLAGS="-L/opt/montavista/pro/devkit/ppc/82xx/target/lib
-L/opt/montavista/pro/devkit/ppc/82xx/target/usr/lib -static"
--with-sys-contact="[email protected]" --with-sys-location="china"
--with-endianness=big --disable-manuals --disable-scripts --disable-md5
make && make install succeed!
But when I operated on the same objects as before:
[r...@virtual-linux net-snmp-5.4.1]# snmpwalk -c private localhost
netSnmpHostsTable
NET-SNMP-EXAMPLES-MIB::netSnmpHostsTable = No Such Object available on this
agent at this OID
[r...@virtual-linux net-snmp-5.4.1]# snmpget -c private localhost
netSnmpExampleInteger.0
NET-SNMP-EXAMPLES-MIB::netSnmpExampleInteger.0 = No Such Object available on
this agent at this OID
the error appears.But It can return correct results when I operated on MIBII
objects such as interfaces,system.
when I trigger the debug on snmpd using snmpd -f -Le -d, it shows:
[email protected]:~# snmpd -f -Le -d -c /usr/share/snmp/snmpd.conf &
[1] 143
[email protected]:~# UCD-SNMP version 4.2.6
And the output is as follows:
