I've installed ssh and sendmail as well as apache webserver. I chose medium security. After the install, I did a portscan on this box and it revealed the following ports were open: 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 :79 finger 192.168.1.x :80 www-http World Wide Web HTTP 192.168.1.x :111 portmap 192.168.1.x :513 login 192.168.1.x :514 shell cmd 192.168.1.x :587 unknown service. Can anyone tell me what ports 111, 513, 514 and especially 587 are open for, and if they are necessary for a web server. Should I close them? Thanks.
