I can telnet to the oracle-port 1521. Everything should be OK.

No I do not have the full client installed. Perhaps I should grab them
from oracle and retry.

OK, thanks for the pointer, but still no luck.
export TNS_ADMIN=/home/holl/software/oracle
cat /home/holl/software/oracle/tnsnames.ora
ORACLESP =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.4)(PORT =
1521)) )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = oraclesp)
    )
  )
