Why netflow?

Recently, we're facing with network congestion, especially on our Wan Link.


We tried to find the culprit for this problem, but nothing much came out of cacti and ntop. So we decided to download and test this netflow reporting tools called Netflow tracker from Crannog Software. The installation is very easy, and we managed to find the cause of the trouble in just few minutes.


After identifying the source of problem, we decided to disconnect the server from the network. Traffic flow back to normal.
