[Linux/MMU] net-snmp AgentX activation problem

Hi All,

I need SNMP with masterX support for my project, but I cannot turn AgentX master support on. I have added 'master agentX' in snmpd.conf, but I get a 'Warning: Unknown token: master' when I'm starting snmpd:

--- Quote Start ---

root:/> cat /etc/snmp/snmpd.conf

rwcommunity public

master agentX

agentXsocket /var/agentx/master

agentXPerms 777

root:/> snmpd -Le -Dagentx

agentx/subagent: init_subagent sess 0000a3e8

agentx_register_app_config_handler: registering .conf token for "agentxsocket"

agentx_register_app_config_handler: registering .conf token for "agentxperms"

agentx_register_app_config_handler: registering .conf token for "agentxRetries"

agentx_register_app_config_handler: registering .conf token for "agentxTimeout"

/etc/snmp/snmpd.conf: line 2: Warning: Unknown token: master.

agentx/config: port spec: /var/agentx/master

agentx/config: port permissions: 777

agentx/config: socket permissions: 777 (511)

NET-SNMP version 5.2.1

--- Quote End ---

I can also see that snmpd doesn't create the '/var/agentx/master' socket.

Because all build/include/.../agent/ generate '.h' files define USING_AGENTX_... to 1, agentx support should be activated, but obviously not.

Any idea?

Thanks in advance,

Fred

    Yes.

    For an unknown reason, the last line of 'user/net-snmp/net-snmp-5.2.1/include/net-snmp/agent/net-snmp-agent-includes.h' was commented, disabling the include of 'net-snmp/agent/agent_module_config.h'.

    As a consequence, 'USING_AGENTX_xxx' were not defined, and the code managing the 'master' feature not compiled.

    I have also modify 'Makefile.top' to add '-fno-tree-loop-opt' 

    diff --git a/user/net-snmp/net-snmp-5.2.1/Makefile.top b/user/net-snmp/net-snmp-
index 298ec0c..3227c95 100644

    Tschüs !

    Hi franz,

    That is very strange: if you're using 'net-snmp-5.2.1', agentx is included by default.

    The should be true if CONFIG_USER_NETSNMP_SNMPD_MINI is *NOT* set, i.e. 'Build mini agent' is unselected in menuconfig...

    Hum, I re-read my answer and can see a typo error : I wanted to write 'This (and not 'The') should be true if CONFIG_...'.

    In other words, you *must* unselect 'Build mini agent' if you want the AgentX functionality - in my configuration, 'net-snmp' is the only option selected) -, and you have *not* to modify the top Makefile.

    For the other questions (how i use agentx???? which basics commands???? ), I'm following the Net-Snmp tutorials and discover this new (for me) world...

    Good luck,

    Fred
