    Is my Redhat 9 safe with all this ports Open?

    Goodday.

    I have a Aztech 4 port router a RH9 behind it.

    I did a NMAP on the Router and i got this results:

    Interesting ports on
    adslXXX.dynXXX.pacific.net.sg (210.24.XXX.XXX.):

    (The 1599 ports scanned but not shown below are in state: closed)
    Port State Service
    80/tcp open http
    255/tcp open unknown

    Are this ports safe or do i have to close them.

    And i did a NMAP scan on my RH9

    Interesting ports on (10.0.0.X):
    (The 1594 ports scanned but not shown below are in state: closed)
    Port State Service
    22/tcp open ssh
    80/tcp open http
    111/tcp open sunrpc
    139/tcp open netbios-ssn
    443/tcp open https
    901/tcp open samba-swat
    6000/tcp open X11

    By the way i have amule running, i wonder if the ports are reflected here.

    Please advise on what uncessary port i have to close to secure my PC .
    Thanks.
    Oh yah... Additional info I am also sharing files between my RH9 and Win 2000.

    Only run the services that you will need, and make sure you have the latest updates and patches. Read up on the services that you need to find out what ports and services are to be open and run. Here is a good list of port numbers and services

    Just out of curiosity, from what side did you scan the router? The scan is far more accurate if it's done from outside your network.
    Real security doesn't come with an installer.

    Did you do an Nmap scan on your Redhat box from the Redhat box?

    Most likely the router has an internal web interface to configure it and that is why port 80 is open on the router. Since you are most likely scanning from inside (and therefore trusted as far as the router is concerned) your network you are getting incorrect scan results.
