    I ran this test, if all my ports but the RPC is closed do I need a firewall?

    The scan only represents a snap shot from the time the test was ran, with that in mind who is to say that one of those ports may become exposed with the launch of a application or service on your system.

    A big part of firewalling is outbound protection which you currently have none of, you may become infected by a virus/trojan or any type of malware that has the ability to provide a back door to yor system, with a firewall in place you stand a chance of preventing that exposure.

    Most test sites only scan common ports, you may be exposing something above the 1024 mark.

    I would overall say if your on a high speed connection then you should firewall the box.

    However, if you keep it patched and secure and use the correct Restrict Anonymous settings then you system is OK.

    I recommend you go for the higher level of security unless you plan to keep a close eye on internet activity and activity of apps on your system.

    thanks for the response

    I think i'll try the Sygate firewall ... I used to use norton .. but it slows the pc down to a crawl :)

    can you or someone reccomend a better site to scan more ports?

    Keep in mind that when someone probes you that if you have your firewall on a set properly, the 'prober' will not get a reply back from your computer and there's a good chance he'll move on to his next victim.

    With no firewall running but and having just your ports closed, the 'prober' will get a reply telling him the port is closed, and may try harder to access your PC.

    computercops.biz offers a NMAP scan that is pretty good.

    pcflank.com used to over a complete scan but i dont think they do so now.

    dslreports.com 's Secure Me Now (Slow scan) is good

    www.hackerwhacker.com is a nice bet

    Then of course you have:


    Also you may want to try Local Port Scanner (LPS) it performs a port scan on the local host. I had limited success with it however.

    Also you could use SuperScan from foundstone to check your system from a remote host or even locally, i belive using "localhost" as the target will work.

    Oh and why not give NMAP NT a blast if your on a LAN :)
