help sql*net V2

After testing sqlnet v2 10 days long i gave it up. After creating the necessary files for a client -server
(both IRIX6.0/Oracle 7.0.15) connection in a tcp/ip networkdomain with
sqlnet version 2.0 i start the listener(and it works i testing it with a telnet on port 1521 ) but its impossible to get a connection to the server
(ora-12545).

Is an entry in the oratab necessary?
Is an create database link from the client required? I dont understand the logic of oracle communities how can oracle resolve the ip-address from the server??
I hope anybody in the world can explain me the necessary steps or send me information about sites where i can get further informations. Thanks a lot
