Why Can't I Access Files on a Digital UNIX Server?

If the server doesn't support WebNFS then the client will use the MOUNT protocol. Some mount daemons will reject mount requests if they come from a client that cannot be resolved through a reverse DNS lookup or if the client is using an unprivileged source port (not less than or equal to1024). Digital Unix server administrators should check the settings of the mountd's -i and -n options.
