The basic set-up is as follows:
1. G4 is connected to phone line
2. Mac OS X on G4 is configured to use the internet via dial-up
2. iBook is connected via a CROSSOVER* ethernet cable to G4
3. On your G4 Internet Sharing is turned ON in "System
Preferences:Sharing:Internet" and you are sharing "To: Built-in
Ethernet"
4. The Mac OS 9 TCP/IP Control Panel on your iBook is configured to
use the ETHERNET port and is using DHCP to obtain IP address
To use internet on the iBook through the G4:
1. Connect to internet on G4 by dialling into ISP
2. With iBook connected to G4 with appropriate cross-over cable open
up an internet application and start browsing the web
3. When you're done browsing the web tell the G4 to disconnect from
the internet.
Troubleshooting: if the G4 is connected to the internet but the
internet is not being shared open up the Internet preferences pane and
make sure that sharing is turned on.
FYI:
* There are two types of ethernet cable of relevance:
1. patch; or,
2. crossover.
Normally you use a 'patch' cable to connect a computer to a
switch/router and you use a cross-over cable to connect
switches/routers to each other or computers to each other. That said,
newer Mac laptops (and maybe desktops) don't care what cable is used
-- they can automatically use both types of cables.
Note: your iBook is probably too old to use either type of cable
interchangeably and you should be using a cross-over cable.
You can tell if you have a 'patch' or a 'cross-over' cable. Put the
connectors side-by-side. If the wire colours are in IDENTICAL
positions you have a patch cable. If they are in different positions
(i.e. "crossed over") then you have a cross-over cable.

What software were you using to share the internet (via ethernet)
between the two OS 9 computers? IPNetShare (just remembered the
name)... <http://www.sustworks.com/>... they apparently even have an
OS X version, and one of their apps is free for OS X.

Your iBook would _in theory_ be less vulnerable since it's going
through a pretty restrictive DHCP server on the G4.
HOWEVER, in practice you DO NOT have to worry about vulnerabilities,
especially with
Mac OS 9. Mac OS 9 is for all practical purposes INVULNERABLE to attacks!!!
