I've installed Vuze and now I'm getting this message sometimes:

      On of your application (probably Telnet) appears to be making a potentially unencrypted und unsafe connetion to port 23.

I checked my open ports with cports but I cannot find any. I've also looked in the system events to no avail. Where do I need to look in the system events for this message and what is this message meaning?

It appears that your machine is telneting somewhere... or at least using going to another host at port 23. Telnet is unencrypted and not really safe to use since someone running a packet capture (like Wireshark) can see everything you are sending to that port 23.

The netstat command in a Command Prompt window will show a list of listening programs and outgoing connections

C:\>netstat -ab

  • Can I sort it like in Linux? – Gigamegs Apr 25 '12 at 15:15
  • @David: If you want Windows to be like Linux, you may wish to install Cygwin, unxutils or gnuwin32. Otherwise you'll have to wrestle with weak command-prompt shell & tools or learn PowerShell. – RedGrittyBrick Apr 25 '12 at 15:18
