FACED(9.5) FACED(9.5) NAME faced - network face server SYNOPSIS /usr/net/face.go DESCRIPTION The network face server provides a database of 48x48 bit icons and other facial representations. It is implemented as a network file sys- tem similar to netfs(8). The file system, conventionally mounted on /n/face, has a fixed three- level hierarchy. The first level is a machine name, the second level a user name, and the third level a resolution. Thus the file is the standard face icon (for user pjw) on machine kwee: .......................................... Many local users also have 512x512 byte high-resolution faces, named 512x512x8. Other resolutions may also be present for a particular face. One-bit images are stored in the format used by icon(9.1); eight-bit images are arrays of bytes. The directories for machines sharing a user community, such as those on a Datakit node, are linked together and given a name appropriate to the community. For example, /n/face/kwee is a link to /n/face/astro. To access the face for a mail name machine!uid take the result of the first successful open from the following list of files: /n/face/machine/uid/48x48x1 /n/face/misc./uid/48x48x1 /n/face/machine/unknown/48x48x1 /n/face/misc./unknown/48x48x1 The directory misc. holds faces for generic users such as and The face server is made available on a machine by running /usr/net/face.go from rc(8). The face server data is administered by a pair of ASCII files that as- sociate related machines and faces. The machine table attaches ma- chines to communities; in it the line kwee=astro puts machine in community The people table associates a machine/user pair in the face server with a file in one of the source directories or Thus astro/pjw=pjweinberger causes the images stored in source files named to be available in the face server in directory /n/face/astro/pjw. As well, each disk file used by the face server is linked (by its original name) into the di- rectory /n/face/48x48x1 or /n/face/512x512x8 for easy access to all the images. FILES directory of low resolution faces directory of high resolution faces people/file equivalences machine/community equivalences SEE ALSO netfs(8), face(9.7), icon(9.1), vismon(9.1) BUGS After updating the tables, an indeterminate time may pass before the new faces are available. All face server files are unwritable. FACED(9.5)
