Hi ,
I am trying to extend the snmp agent by doing the following
- I built a minimal agent by using the configure script ./configure
--enable-mini-agent
- I compiled "ONLY" the ifTable using mib2c with the following options:
- Netsnmp-style-code
- Tables where the list of rows is external to the agent.
- An API layer that attempts to reduce the amount of SNMP specific
knowledge required to implement the module.
-* All other table options where set to defaults*
- I used the "dlmod" shared object method of trying to extend the agent by
placing the shared object name and /path/to/object in the snmpd.conf file
- I did not modify any section of the code yet. I want to try and load the
shared object as is.
- When i try to start the agent , the dlopen fails :
could not open /proc/net/if_inet6
cache has existing timer id.
dlopen failed: /usr/lib/ifTable.so: undefined symbol:
netsnmp_container_table_row_extract
NET-SNMP version 5.2.3
- I did a nm -u on the shared objects and a number of un defined references
were listed
U malloc@@GLIBC_2.0
U memcpy@@GLIBC_2.0
U memset@@GLIBC_2.0
U netsnmp_baby_steps_access_multiplexer_get
U netsnmp_baby_steps_handler_get
U netsnmp_cache_create
U netsnmp_cache_handler_get
U netsnmp_check_requests_error
U netsnmp_check_vb_type_and_size
U netsnmp_container_find
U netsnmp_container_table_handler_get
U netsnmp_container_table_row_extract
U netsnmp_create_data_list
U netsnmp_extract_table_info
U netsnmp_get_row_merge_handler
U netsnmp_handler_registration_create
U netsnmp_inject_handler
U netsnmp_register_table
U netsnmp_request_set_error
U netsnmp_request_set_error_all
U netsnmp_set_request_error
U netsnmp_table_helper_add_indexes
- Could any one help me with this ?
thanks
Swaroop
