Today we have received this typical question: "I'm trying to find a load testing product which would allow me to load test flash applications. I've tried webserver stress tool 7 and it doesn't seem to enable me to simulate usage of a flash application. Can you tell me if this can be done, and if so, how? "

Paessler MIB Importer updated to version 1.1

An updated version of our MIB Importer Tool is available on the website. With this software you can easily import MIB files and convert them into OID libraries for PRTG Traffic Grapher and IPCheck Server Monitor.

In this latest version V1.1 we have improved the compatibility so that many "not-100%-RFC-conform" MIB files can now be loaded and converted (most in-the-wild MIB files are not conform to the RFCs...).

Remotely fixing a PC via the Internet - Free & Instantly

Every once and a while you come across the task to remotely control a PC across firewalls, NATs etc. We are not talking about controlling a PC or server in your LAN or VPN (where you have full control over the firewalls, NATs etc.). In such a case I still prefer Windows Remote Desktop for its speed inside your own network.

I mean fixing a client's PC, a co-worker's notebook in an Internet Cafe, or even Mom's PC without the need of travelling there.
