[Linux/MMU] net-snmp AgentX activation problem

[Altera_Forum]

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

Hi fred....... 

 i have the same problem ...... do you have any progress on it????   regards  Franz Wagner

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 --- a/user/net-snmp/net-snmp-5.2.1/Makefile.top +++ b/user/net-snmp/net-snmp-5.2.1/Makefile.top @@ -81,7 +81,7 @@ RANLIB = : # libtool definitions .SUFFIXES: .c .o .lo .rc .c.lo: - $(LIBTOOL) --mode=compile $(CC) $(CPPFLAGS) $(CFLAGS) -c -o $@ $< + $(LIBTOOL) --mode=compile $(CC) $(CPPFLAGS) $(CFLAGS) -fno-tree-loop-opt .rc.lo: $(LIBTOOL) --mode=compile windres -o $@ $< At last, I'm using NON_SMP_BUILD=1 make to generate my kernel with parallele make disabled.  Tschüs ! Fred

Hi fred .........thanks to your tip........ 

 i change the makefile in /user/net-snmp/ and add  --with-mib-modules=agentx and it works :)  thank you ......   Franz Wagner

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...  Fred

Hi Fred !!!!  

 yes i use net-snmp 5.2.1 ....... but i select mini agent..........  why i should be true if CONFIG_USER_NETSNMP_SNMPD_MINI is *NOT* set???  how i use agentx???? which basics commands???? do you know????  thank you....  Franz Wagner

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
