  • 枫下家园 / 电脑用户 / 如何知道自己的机器开了什么端口？（win 2000 pro） 谢谢！！ -csguy(jecky); 2001-11-21 {454} (#270287@0)
    我用roger公司的上网服务，可它最近把我的服务停了，说我开了Web, Telnet server.

    邮件内容如下：


    > Interesting ports on cr610252-a.ym1.on.wave.home.com (24.101.160.77):
    > (The 1538 ports scanned but not shown below are in state: closed)
    > Port State Service
    > 23/tcp open telnet
    > 80/tcp open http

    可我没有开，如何知道自己开了呢？
    环境如下：

    BroadBand SOHO Gateway 后面有三台win2000 pro.


    Thanks a lot!

      you (or your OS) DID open those ports anyway, the best way to fix that problem is to download some firewall software to protect your host from being scan by Rogers. also you could download some scan or security software to scan you host to figure out what ports are open, just like Rogers did. hope that would be helpful.
      • but I open 21 25 80 110 443 for almost 1 year. None says anything. Sometimes @home scan the network, but nothing had happened.... -heian(㊣天使); 2001-11-22 (#270337@0)
        • I think that depands, say depends on your traffic volume whatever. since I was suspended by Rogers due to opening FTP service two months ago, then I installed Sygate firewall and so far so good. -songl(风); 2001-11-22 (#270345@0)
    • Is BroadBand SOHO Gateway a router(hardware)?then may be 80 and 23 were its default admin ports.In win2000, maybe you would like to use netstat -a to see your network state -iteam0(ribon); 2001-11-22 (#270363@0)
    • Hehe, that's the output of nmap. If they don't want people to open those ports, why don't they just block them like they do with TCP 137-139. -dennis2(Dennis); 2001-11-22 (#270371@0)
    • 谢谢，不过我还有问题 -csguy(jecky); 2001-11-22 {214} (#270577@0)
      看来这里人气确实很旺啊，早上来看就有热心人回答了。谢谢。

      BroadBand SOHO Gateway is router, so I think roger company scanned my router.

      How can I turn off these two ports?
      What is 'nmap'?

      Thanks a lot!
      • 1. See if you can block those ports through the admin interface. 2. nmap is a very popular security auditing tool, see link. -dennis2(Dennis); 2001-11-22 (#270801@0)
