FastNetMon Advanced licensing server

FastNetMon Advanced licensing server

In this article you can find details about FastNetMon’s license server implementation.

When you install FastNetMon for  the first time it uses your external and internal IPs (if use NAT) and information about hardware to generate license.

It uses following hardware details:

  • CPU model
  • Memory amount
  • Number of logical CPUs

If you change any of these hardware options FastNetMon will issue new license automatically (you need to have active Internet connection) when you change it reasonable number of times (few times per week). If you change it so often our support team will contact you and after that we may limit number of allowed hardware assignment changes.

If you’re thinking about changing external or internal IP address, please create ticket to our support team before making any actions. Any IP relate changes will affect license allocation process.

For monitoring reasons, FastNetMon sends following information to license server:

  • Current incoming speed
  • Current outgoing speed
  • Number of hosts in network
  • Number of observed Netflow/IPFIX flows per second (since 2.0.171)
  • Number of observed sFlow headers per second (since 2.0.171)
  • Version of FastNetMon
  • Enabled plugins (af_packet, sflow, netflow)
  • Time required for speed calculation

FastNetMon does not send any pcap dumps, hosts in your network or any other sensitive information to our servers.

We offer cloud licensing option. In cloud license mode FastNetMon uses only your external IP to allocate license and ignores internal IP changes completely.  Please contact our sales team to get more information about this option.

If you deployment does not have any external connectivity we can allocate offline licenses which does not require connection to licensing server. If you need this type of license, please discuss it with sales team.
