• Download the package :
  https://public.panagenda.com/download/idna/alma9-snmp.zip
  
  
• Copy zip file to folder /root/ on the appliance (using WinScp)
  
  
• Extract contents of zip file:

  unzip alma9-snmp.zip
  
  

• Check if SNMP is already installed:

  systemctl status snmpsnmpd.service
  
  

• If the service answers, you can SKIP the next paragraph "Install SNMP Server"

...

• Enter directory "snmp":

  cd /root/snmp

  rpm -ivh --force *.rpm

...

• Enter directory "snmp":

  cd /root/snmp
  
  

• Stop SNMP server:

  systemctl stop snmpd
  
  

• Back up old snmp config file:

  mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.orig
  
  

• Generate new UUID for next step (copy to notepad for further use):

  uuidgen
  
  

• Edit snmpd.conf to enter newly generated GUID

  nano ./snmpd.conf
  
  

• Replace string "GUID" in line .1.3.6.1.2.1.47.1.1.1.1.11.0 with new GUID
  Example: override .1.3.6.1.2.1.47.1.1.1.1.11.0 octet_str "6c422afb-b420-4f3b-84ff-cfb9e1431bde"
  
  
• Check if hostname needs to be overridden (e.g. to show FQDN instead of CN)
  Uncomment and edit line .1.3.6.1.2.1.1.5.0 if necessary
  
  
• Modify "syslocation" and "syscontact" as needed
  
  
• Copy new config file to /etc:

  cp ./snmpd.conf /etc/snmp/
  
  

• Restart SNMP server:

  systemctl restart snmpd
  
  

• Make sure SNMP service starts at boot time:

  systemctl enable snmpd
  
  

• Test configuration:

  snmpwalk -v2c -c public localhost

  and/or

  snmpget -v1 -c public localhost .1.3.6.1.2.1.47.1.1.1.1.11.0
