For an explanation of what a TCP or UDP port is, see the "IP Ports" section of "Mac OS X: What Is a Port?" 4. In Mac OS X Server v10.0.3 and later, some services that do not use well-known ports register with portmap. Use therpcinfo -pcommand in Terminal to see 5. The NetInfo parent-child model has replaced Shared Users and Groups in Mac OS X Server 10.0.3 and later. 6. With performance cache enabled in Mac OS X Server v10.0.3 and later, Apache is on port 16080 and cache is on port 80. 7. This table includes features and ports used by Mac OS X v10.3. Earlier versions of Mac OS X do not have all the features listed here. 8. For Mac OS X Server v10.3 VPN service: PPTP uses the IP-GRE protocol (IP protocol 47). L2TP/IPsec uses the IP-ESP protocol (IP protocol 50, ESP). 9. This is for current Jabber authentication methods. The previous method also requires port 5223. 10. servermgrd only listens on this port in Mac OS X v10.3.9 and earlier. With Mac OS X v10.4 or later, it listens on 311 only. 11. The output of Terminal commands may replace the port number with the label that is listed in /etc/services.
