The HEAnet Looking Glass provides you with a view of the internet exactly as the HEAnet routers see it. This service is open access, available to both HEAnet and the general public and can be found in http://lg.heanet.ie. As it is HEAnet policy, both IPv4 and IPv6 commands are available to consult the BGP, routing or multicast routing tables, ping or traceroute.
We are currently trialling Netflow Tracker and allowing our clients to view this information via a web-based portal with federated access.
Netflow Tracker takes information (Netflow Version 9) from our client’s connections and stores them in a database for 14 days.
A graphical user interface then displays this information to our clients. Each client can only access their own connections. This real time monitoring of NetFlow allows clients to have the detailed information necessary to identify, isolate and troubleshoot network performance issues. It takes the raw numbers that make up the Netflow data generated from a routers interface and converts them to easy to read/interpret charts for analysis. Clients can query IPv4 and IPv6 traffic
It answers such questions as
- Exactly what makes up my network traffic?
- Who are the users?
- What applications are they using?
- Who and what are consuming the bandwidth?
- Are there worms and viruses in my network, where are they, where did they come from, and where are they going?
For more information, please contact the HEAnet Network Operations Centre on 01-6609040, or at email@example.com
There are two stratum-1 time servers within the HEAnet network. To ensure uptime and precision one of the servers is located in Dublin and synchronizes to the Anthorn MSF signal; the second server is located in Waterford and synchronizes to GPS. This service, available over IPv4 or IPv6, can be accessed by any host in any of the HEAnet client networks and all that is needed is to configure your hosts to synchronize with ntp1.heanet.ie and/or ntp2.heanet.ie
