snmp linux win

I use snmp protocol on linux, now I have to use snmp on win, i use pc linux.
I have activated the service snmp on win but I can not question him on my linux pc, you have any suggestions?

there was a firewall on windows :mad:
now i have make a simple script

echo "100"

i have change snmpd.conf

exec nOID /bin/sh path of my script

when i call snmpget on this oid return 100 but as string not as an integer, why?
