SQL Net V1

I am trying to connect a NeXT (Unix) application to oracle running on solaris machine. The Demo NeXT application need SqlNet V1 to be running on the server machine.

I tried to install SQLNET v1 on solaris machine and tried to loop back using sqlplus scott/tiger_at_T:hostname:dbname but it is giving the following error:

ORA 03113 end-of-file on communication channel

orasrv is running, port 1525 is defined in services file

Is there any more variable that need to be set?

Note: SqlNet V2 is running fine on the Solaris Machine.
