The following network services cannot be used on a Freedom server, at least not on their standard ports:
DNS. Name servers cannot be run on Freedom servers because there is a caching name server on the physical machine itself running on that port. The machine’s caching name server is used by all of the accounts on that machine to decrease the load placed on our core nameservers.
NFSD. NFS is used as the export mechanism for the Freedom Flexible File Sharing system. Because it is used on the physical machine itself, a Freedom server cannot use NFS as either a server or a client.
SNMP. SNMP is used by our network and system monitoring systems to monitor the physical machines that host Freedom accounts. As such, a Freedom server cannot run its own SNMP daemons.
SunRPC [a.k.a. portmapper]. Portmapper is used on the physical host machine both for NFS and by our tape backup system. Because of this, applications requiring Sun’s Remote Procedure Call system (portmapper) will not run properly on a Freedom server.
