As the protocols do not require any special privilege to implement, this is not an issue on the Hurd. +In Mach parlance, a *translator* is what they name a *server*: a process that +participates in [[RPC]] interactions. In the Hurd, a translator is a server +that is additionally attached to a filesystem node. Thus, it is quite common, +even in the Hurd context, to speak about *server*s if you're stressing the RPC +part, and on the other hand about *translator*s if you're stressing the +filesystem part: a translator implements the [[interface/fs]] and +[[interface/io]] interfaces. For example: *the [[pfinet]] server implements +the socket API calls (which are mapped by [[glibc]] to equivalent RPC calls)*, +compared to *a [[libdiskfs]]-based translator implements a filesystem, based on +a backing store*. + To learn how to write a translator, read the code!
