AgentX in windows (netsnmp 5.2.1.2 + example-demon)

Hi, 
I wrote a subAgent for Linux, it works just fine, 
When I was asked to add support for Windows server 2003 too, I had a 
lot of problems. I am asking you for help please: 


After applying some patches, I installed net-snmp 5.2.1.2
<http://5.2.1.2>in my windows
machine using cygwin, using those steps: 
1. configure --with-mib-modules="host agentx disman/event-mib 
examples/example" --with-out-mib-modules=host/hr_net 
work 
2. make 
3. make install 


OK.. Now I am trying to compile example-demon (form agentx tutorial 
from net-snmp official site). 
I am running the snmpd: 
c:\usr\bin\snmpd -f -L -c c:\usr\share\snmp\snmpd.conf -x localhost:705 
-Dagentx 
snmpd.conf looks like this: 
########################################################### 
# SECTION: Access Control Setup 
rwuser root 
rouser root 
rwcommunity public 
master agentx 
# end of snmpd.conf 
##################################################### 


snmpd output is: 
""" 
c:\usr\share\snmp\snmpd.conf -Dagentx 
agentx/subagent: init_subagent sess 00325ea0 
agentx_register_app_config_handler: registering .conf token for 
"agentxsocket"

"agentxperms"

Turning on AgentX master support. 
agentx/master: initializing... 
agentx/master: initializing... DONE 
NET-SNMP version 5.2.1.2 <http://5.2.1.2> 
""" 


Then I opened a cygwin window and compiled example-demon.c, here is the 
code: 
############## 
# example-demon.c 
#include <net-snmp/net-snmp-config.h> 
#include <net-snmp/net-snmp-includes.h> 
#include <net-snmp/agent/net-snmp-agent-includes.h> 
#include <signal.h> 


#include <nstAgentSubagentObject.h> 


static int keep_running; 


RETSIGTYPE 
stop_server(int a) { 
keep_running = 0; 

 } 


int 
main (int argc, char **argv) { 
int agentx_subagent=1; /* change this if you want to be a SNMP master 
agent */ 
int background = 0; /* change this if you want to run in the 
background */ 
int syslog = 0; /* change this if you want to use syslog */ 

/* print log errors to syslog or stderr */ 
if (syslog) 
snmp_enable_calllog(); 
else 
snmp_enable_stderrlog(); 


/* we're an agentx subagent? */ 
if (agentx_subagent) { 
/* make us a agentx client. */ 
netsnmp_ds_set_boolean(NETSNMP_DS_APPLICATION_ID, 
NETSNMP_DS_AGENT_ROLE, 1); 
netsnmp_ds_set_string(NETSNMP_DS_APPLICATION_ID,NETSNMP_DS_AGENT_X_SOCKET,"­localhost:705");



} 


/* run in background, if requested */ 
if (background && netsnmp_daemonize(1, !syslog)) 
exit(1); 
/* initialize tcpip, if necessary */ 
SOCK_STARTUP; 


/* initialize the agent library */ 
init_agent("example-demon"); 


/* initialize mib code here */ 


/* mib code: init_nstAgentSubagentObject from 
nstAgentSubagentObject.C */ 
init_nstAgentSubagentObject(); 


/* initialize vacm/usm access control */ 
if (!agentx_subagent) { 
init_vacm_vars(); 
init_usmUser(); 
} 


/* example-demon will be used to read example-demon.conf files. */ 
init_snmp("example-demon"); 


/* If we're going to be a snmp master agent, initial the ports */ 
if (!agentx_subagent) 
init_master_agent(); /* open the port to listen on (defaults to 
udp:161) */ 


/* In case we recevie a request to stop (kill -TERM or kill -INT) */ 
keep_running = 1; 
signal(SIGTERM, stop_server); 
signal(SIGINT, stop_server); 


snmp_log(LOG_INFO,"example-demon is up and running.\n"); 


/* your main loop here... */ 
while(keep_running) { 
/* if you use select(), see snmp_select_info() in snmp_api(3) */ 
/* --- OR --- */ 
agent_check_and_process(1); /* 0 == don't block */ 
} 


/* at shutdown time */ 
snmp_shutdown("example-demon"); 
SOCK_CLEANUP; 


return 0; 

 } 


# end of example-demon.c 
###################### 

Then I ran example-demon.exe, it says that "example-demon is up and 
running"!!!!! 


BUT, when I check the subagent's MIB it seems not working: 
c:\snmpget -v 2c -c public localhost 
NET-SNMP-TUTORIAL-MIB::nstAgentSubagentObject.0 
==> NET-SNMP-TUTORIAL-MIB::nstAgentSubagentObject.0 = No Such Object 
available on this agent at this OID 


!!!!!!! 


I spent some days trying to figure it out, I couldn't. Can you please 
help me. 


P.S 
1. netstat -a shows me "TCP pc_name:705 pc_name:0 LISTENING" 
2. When I try to run the example-demon without running the master, I 
got the same behavior, it says that it's up and running!!, but in fact 
it's not. 
3. I am running snmpd and example-demon from MS window (not form cygwin 
window), I don't know if that's matter. 


Thanks in advance.
