- No. Providing you are not running any software on the computer that will

-
- Nope. Can't be done. Providing you don't have software running on the
- computer that will allow such things, it cannot be done.
-
- : 3. Scenario: I am connected to the net via dial-up PPP (or SLIP I suppose).
- : Can some clever person actually tunnel back through my connection to rape and
- : pillage my PC (and others on a LAN)? If so, is there a way to secure this?
-
- Yes. If you have a SLIP or PPP connection means that you have your own IP
- address that people can ftp/ping etc etc your computer. Now, once again,
- you have to have software running on your computer that will allow ftp etc
- connections.
-
- Once again, as long as you don't have any software (TSR etc) running to
- allow stuff like this, there is no magical way someone can access your
- computer.
-
- : Thanks in advance for any hints, pointers or helpful FAQs.
