The best way to enumerate the snmp is installing the next package and modifying the /etc/snmp/snmp.conf and comment the mibs line (monitored machine) and filter by hrSWRunParameters
sudo apt-get install snmp-mibs-downloader snmp -y
#Filter only by process
snmpbulkwalk -v2c -c public 10.10.11.248 HOST-RESOURCES-MIB::hrSWRunParameters
hrSWRunParameters Show the parameters utilized when a program or process has been ran on the system.
# Enumerate the SNMP Service
Intrusionz3r0X@htb[/htb]$ snmpwalk -v2c -c public 10.129.14.128
onesixtyone -c /opt/useful/SecLists/Discovery/SNMP/snmp.txt 10.129.14.128
