Step 3 Choose PPP and click Accept
Step 4 Enter the ISP’s phone number, your user name and password. Note that
the password will be stored unencrypted in a text file, so if security is an
issue, you may choose to not enter the password until actually dialing.
Step 5 Click Accept to save the new record.
Step 6 To dial, select the connection from the list of connections. A new Interface
tab will appear. If you did not enter your password when setting up your
connection, go to the Connection tab and enter the password. When exiting
the dialer, click Cancel to exit so that your password will not be saved.
Step 7 Disconnecting is similar: Start up linuxconf (if you closed it), go to the
PPP/SLIP/PLIP menu item, select your connection and click disconnect.
Some General Tips
l The permissions on pppd have to be changed to suid root if other users besides
root are to be able to make PPP connections. This is the same with KPPP. An
alternative is to create a “modem” group and give read/write permissions to
that group. Then add the users who are allowed to use the modem to that
group.
l A secure way to start up PPP is to make a login specifically for PPP access
whose shell is a call to pppd.
l Starting pppd with the “debug” option prints some informative information
to the screen
l The KPPP FAQ provides some good additional troubleshooting tips.
