* Bennett Hui <bhui@mail.com> [20001018 11:34]: =>Thanks for the replies on some of the open ports on my webserver, I've =>closed off all unnecessary ports except for one that no one seems to know =>what it's used for. I'm not so concerned as to what service runs on it, but =>more over how to close this port. When I do a portscan on my box, I get the =>following information: => =>192.168.1.x :21 ftp =>192.168.1.x :22 ssh SSH Remote Login Protocol =>192.168.1.x :23 telnet =>192.168.1.x :25 smtp mail =>192.168.1.x :53 domain nameserver =>192.168.1.x :80 www-http World Wide Web HTTP =>192.168.1.x :587 unknown service. => =>It would be great if anyone knew what port 587 was used for (it just came =>with my install of 4.1.1-RELEASE), but more importantly how can I close it =>off. I suppose the quick and easy way would be to block it off with ipfw, =>but is there a line in a config file where I can disable this service? I did not have time to read ALL but I believe the clue is right in front of you in /etc/services ;) HTH -Wash -- Odhiambo Washington Inter-Connect Ltd., wash@iconnect.co.ke 5th Flr Furaha Plaza Tel: 254 11 222604 Nkrumah Rd., Fax: 254 11 222636 PO Box 83613 MOMBASA, KENYA.
