I have successfully installed Oracle 9.2 on my Linux Server set up with SuSE Linux 7.3 and made a dataware house which I can connect to on the linux PC. The linux PC uses iptables and I have fully opened up the network between the linux PC and any PC which can connect to it through a switch.

I also have a Windows 98 PC with Oracle 9.0.1 installed. I made a sample database there and can connect to it.

I am not able to connect to the database on the linux PC from the windows 98 PC.
tnsping <instance sid>
works though. Connectioni to the linux database from the windows 98 PC worked
with the previous version of oracle. PC Oracle 8.1.6 and Linux Oracle 8.1.5.

I have made a listener on the linux PC and started it. Here is the listener.ora file :

# LISTENER.ORA Network Configuration File: /db1/oracle/9.2.0.1.0/network/admin/listener.ora # Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
(ADDRESS_LIST =

        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )


      (ADDRESS_LIST =

        (ADDRESS = (PROTOCOL = TCP)(HOST = skier.snow)(PORT = 1521))
      )

    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /db1/oracle/9.2.0.1.0)
(PROGRAM = extproc)

    )
    (SID_DESC =
(GLOBAL_DBNAME = SKIER.BALCAB.CH)
(ORACLE_HOME = /db1/oracle/9.2.0.1.0)
(SID_NAME = SKIER)

    )
  )

The status command of lsnrctl is ok.

Here is the tnsnames file on the PC
