Oracle Database Express Edition (XE)

installed according to install guide on Redhat ES 3 (as root)
after install the database starts and sqlplus works.
for example i added remote access to the HTTP:
SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
PL/SQL procedure successfully completed.
but i cannot access web or listener.

i see some references to SElinux to resolve this problem, but as far as i can tell no SElinux is installed (not included in RHES3? /etc/selinux does not exist). iptables are also disabled. i list open ports and they are not there (shuld be even if iptables was enabled).

this is the error message i get when starting lsnrctl as oracle:
-bash-2.05b$ lsnrctl start
