pppd problems

[Gene and Amy Dascher]

I am having problems running pppd on my old 486.  I have installed RH6.1 and have pppd version 
2.3.10.  Everytime I try and run
pppd, I get the following messages:
(This is from my syslog)

messages:May  4 21:47:33 printsrv pppd[637]: The remote system is required to authenticate itself 
but I
messages:May  4 21:47:33 printsrv pppd[637]: couldn't find any secret (password) which would let it 
use an IP address.

Does anyone have ANY idea what might be the problem?  I have gone through EVERY ppp FAQ and HOWTO 
that I can find, and CANNOT figure
this out.  Has anyone had this problem before?

Thanks,
