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?
