Mlink
Shell account users can also access the internet using Mlink which is available on Aminet .
It is like TIA in that it is a one way glass. You can see out, but no one can see in. This is because your machine's IP address is not being used by Mlink. Instead Mlink uses your provider's host's IP address, and then relays the results to your Amiga.
You can ftp, telnet, or Mosaic out, but no one can ftp, telnet, or Mosaic to your Amiga because you do not have an address.
