I wanted to add the Open Source Network Grapher (Open Source Network) to my NSM Router Administration tool collection. Based on the instructions provided by Open Source and Cisco’s 4.9 RELMTS router. I enabled the SNMP server on the router on my Cisco router. Make sure you set up an access list where you don’t want people accessing the service on your Apache Web server on your next Web server. Replace ‘public’ with ‘private’ and ‘[email protected]'”]
