So I believe I have Oracle 8i set up (Red Hat 6.1), and I have created an
initial database (SID=web), but whenever I try to connect, sqlplus quickly
tells me that I have:

ERROR:
ORA-01017: invalid username/password; logon denied

I have tried connecting to Oracle when logged in to Linux as user Oracle in
group dba.  I have tried as root (which is in group dba as a supplementary
member).

So how in general do I set up accounts in Oracle?

How do I get Oracle to respect the accounts and privileges of the underlying
Linux system (using /etc/passwd, etc....)

Thanks!
