Infrastructure Software

Hi all!
I'm having problems on running Oracle on localhost.My current hostname in linux is : localhost.I'm always able to get on EM after I create a new database,but when I restart my computer,I can no longer reach the URL: http://localhost:5500/em ,although I can access the internet.
The listener also was not starting after reboot,so I had to use netca app. to delete and create a new listener.It's working now fine,as per the status,but I can't reach EM :(.
I'm using Suse 9.3.
Can anyone give some suggestions?Thanks.

This is my /etc/hosts file:

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
127.0.0.2 linux.site linux
127.0.0.1 localhost

This is listener.ora

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

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
)
)

and,tnsnames.ora:

# Generated by Oracle configuration tools.

BASE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = base.localhost)
)
)
