Hi all, Just a quick question arising from following another thread. Here is the result of nmap on a FC6 box: $ nmap localhost Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2007-04-18 14:10 EST Interesting ports on localhost.localdomain (127.0.0.1): Not shown: 1670 closed ports PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp 111/tcp open rpcbind 139/tcp open netbios-ssn 445/tcp open microsoft-ds 631/tcp open ipp 670/tcp open unknown 696/tcp open unknown 946/tcp open unknown 2049/tcp open nfs Nmap finished: 1 IP address (1 host up) scanned in 2.036 seconds $ What are the 3 "unknown" open ports? Also I cannot find rpcbind, netbios-ssn nor microsoft-ds under System>Services. What are these services for? Thanks Simon
