Re: [Vserver] snmp & vserver

i have yet to run into a program that cannot be changed from 127.0.0.1 to

similar. someone else will have to answer that one who knows..

we have one instance of cacti running (in its own guest) that monitors our
entire network including all our guest vservers and extended network
components that are in remote places around the nation. i believe all that is
needed is snmp within each guest or location to answer cacti's requests...
snmp uses very few resources... i will have to speak with our tech tomorrow
about this.
