FAQ for IMDetect Monitor Software

Q: The program can't find any adapter. Please help me!

Our programs support most network adapters. You can try to restart your computer first. If you have installed an older version of WinPcap, please install the latest one shipped with our programs.

Q: It can't even capture chat from the same computer. Why?

Basically there are two possible reasons. First, you need to click the start button to let IM monitor software begin to capture data. Second, maybe your default network adapter is not a working one. Click the "config" button to popup a network adapter selection window. If there are more than one adapters in it, try them one by one to find out a working one. On window NT/2000/XP, the working network adapter is shown with name like "\Device\Packet_{3512...}". While on windows 9X, the name like "PCNTN4M", etc. Please note, you may have to click the stop button to make the "config" button enabled.

Q: Only conversations from local computer are shown, but I need monitor chat from other computers on the same LAN, not my own!!!

Maybe your LAN is connected with a switch. Unlike hubs, switches prevent promiscuous sniffing. Fortunately, most modern switches support "port mirroring", "management port" or similar features to enable network administrators monitor LAN traffic through one or more designated ports. By using this feature, you will be able to monitor the entire LAN segment in switched network envirnoment. Please refer to the documentation that comes with your switch for information on availability of such feature and configuration instructions.

But if you don't have such switch, there are still several alternatives available. Please refer to the following FAQ "Q: My switch doesn't support monitoring features. What to do?".

Q: How to configure SPAN or enable port mirroring for my switch?

Due to a variety of configurations for different switch products, we don't have a common instructions. Please refer to the documentation that comes with your switch for information on availability of such feature and configuration instructions. You can also search online to find more information about this.

In addition, there is a 3-step instrution page on how to configure SPAN for Cisco switch.

Q: Why can't it detect some user names?

If you start the IM Monitors after the user has logged in, user name may not be available.

Q: My switch doesn't support monitoring features. What to do?

If you can't or don't want to configure port mirroring for your switch, there are still several alternatives available.
  • Execute the monitor program on your Internet gatesway, ISA 2006 server, router or proxy server if possible. Any Internet traffic will pass through the gatesway, therefore monitor program could capture them.
  • Send some fake ARP packet to your network to cheat your switch. And then switch will forward traffic to other computers to your computer. But it is an inefficient and dangerous way.
  • Use a hub, not switch, and connect both monitoring computer and the ADSL router to the hub. Your existing switch connects to the hub. This way, all the Internet traffic will also pass through your monitoring computer.
  • Downgrade your switch to a common hub

Q: Does your monitor program work with DSL or Modem? It locks my dialup Internet connection on windows 2000.

Our IM monitor programs support modem on windows9x, but don't support on windows 2000 or above. But you can run monitor on those computers not connecting to Modem directly. Concerning DSL, if it dials up on itself, and it acts as a router or NAT, you can run our monitor programs on any computer on your LAN. Otherwise, if you dial up on your computer, please don't run our monitor programs on the dialup computer, but on other computers.

Q: My PC have two CPUs. How can I make your monitor work with it?

Yes, the packet-capturing driver, WinPcap, need upgrade to version 3.0 or above to support SMB. You can download the latest WinPcap from the official site at http://winpcap.polito.it/ directly.
