How to setup Cable Modem to internet

Question

I am new to solaris 8 and would like to connect my sparc 5 directly to the internet via a cable modem.
If anyone out there has a clue on how to configure my system please provide me with the steps to follow.
Thanks

It can be a little tricky. I did it a couple of months ago with an Ultra 5 running Solaris 9, but I'm guessing it's pretty similar.
First, setup your computer to use dhcp.
Here's a handy web page that I found well AFTER I had already painfully configured my system.

If you'd like to use it as a web server, I'd suggest getting a DNS name from dyndns.org. It's free and seems to work well. The only gotcha is that you're IP address can change regularly so you'll have to use a freeware program like ez-ipupdate to keep dysdns updated with your latest IP. Also, dyndns doesn't like getting updates if your IP address hasn't changed, so I had to create a cron that I run hourly that'll update dyndns with my latest IP only if it changes. Here's a copy of it.
#!/usr/bin/ksh
# Used for updating the IP only when necessary.
NEWIP=`netstat -rn | grep le0 | head -1 | awk '{ print $2 }'`
OLDIP=`cat /var/adm/OLD-IP.txt`
echo $NEWIP > /var/adm/NEW-IP.txt
if [ "$NEWIP" != "$OLDIP" ]; then
# Update IP Address
echo $NEWIP > /var/adm/OLD-IP.txt
/usr/local/bin/ez-ipupdate -S dyndns -u username:password -h dns_name -i le0 > /dev/null 2>&1
fi
Good luck!
