The problem was resolved last night, however, I am concerned about the
solution.
In logging into the Shiva box, I was using CHAT to login with the userid
and password. Shiva supports a terminal mode access at this point. I was
under the belief that I needed to access this, since this terminal mode was
the only place I saw to enable PPP. In fact, PPP is an command to be used
here. I was under this assumption based on the PPP HowTo.
When I looked at the Shiva connection, I noticed that the connection address
that I was assigned was the Shiva box itself. Now, typically, I have notice
that I am assigned a different range of numbers. I assumed that the address
assigned to me was due to the terminal mode I was logging into.
Last night, I had THE brainstorm. I knew that Shiva supported CHAP and PAP.
Could it be that I did not need to login to the terminal mode to gain
access? That by enabling one of the two above, I would gain access to the
system directly. I would have my own IP address at last.
I create the pap-secrets and chap-secrets file in the /etc/ppp directory in
hopes that I could used them. However, when I used the auth switch on pppd,
it gave me the error that the authentication files could not be located. I
still have not resolved this problem.
I did find in the man pages a switch called +ua. +ua takes a file which
contains the user and password for PAP authentication. I fired up pppd with
the new chat script that did not login to the Shiva box as a terminal, just
dialed and connected. Bam, I was in. I set up my route and saw the Mecca.
The Internet in all it's gory (not a mistype mind you).
My concern comes that the man pages indicated that this switch was outdated.
Problem to be resolve. Why is it not finding the secrets files? I tried
permissions and everything else I could think of (even the current directory
trick) but no dice.

A couple of questions for you:
Does your ethernet network have valid IP addresses? Does the
Shiva box know that you are a network, and not one host? Do you have
IP forwarding on in the kernel?
