CHAPTER 1 • CREATING A DIAL-UP INTERNET CONNECTION 29
If you are successful, you will see “Connect” in the Login
Script dialog box, as shown in Figure 1.8. If the connection
did not work for some reason, see “Troubleshooting
Your Installation” for tips on resolving the problem.
Troubleshooting Your Installation
This section provides solutions for almost all of the problems
you may encounter with modems. Remember,
though, that some modems simply do not work with
Linux, no matter what you do. Before troubleshooting
your modem, make sure it is compatible with Linux; otherwise,
you will be wasting your time.
An organized approach to troubleshooting pays off. Take
it step by step. Remember what the great Sherlock
Holmes told the baffled Dr. Watson: “When you have
eliminated all of the other possibilities, whatever remains,
however improbable, is the truth.” Now we can start by
figuring out what is wrong with the modem.
Checking Physical Connections
Curing the Modem Blues
Make sure your modem is properly seated in the expansion
slot and that all the connections are snug. Is the
phone line plugged into a standard modular telephone
jack?
When you queried your modem with KPPP, you may have
been told that your modem is “busy,” and that KPPP is
really sorry about this. The sympathy is nice, but you are
given no clue as to how to solve the problem.
