SYNOPSIS

9pserve [ -lnv ] [ -A aname afid ] [ -c addr ] [ -M msize ] addr

DESCRIPTION

On Plan 9, when a user-level file server mounts itself into a name space or posts itself in /srv, the Plan 9 kernel multiplexes the potentially many processes accessing the server into a single 9P conversation. The user-level server need not concern itself with how many processes are accessing it or with cleaning up after a process when it exits unexpectedly. On Unix, 9pserve takes the place of the Plan 9 kernel, multiplexing clients onto a single server conversation and cleaning up after clients when they hang up unexpectedly.

9pserve announces a 9P service on addr and multiplexes any 9P clients connecting to addr into a single conversation with a 9P server on 9pserve’s standard input and output. When a client hangs up, 9pserve flushes any outstanding 9P transactions and clunks any outstanding fids belonging to the client.

9pserve is typically not invoked directly; use post9pservice(3) instead.

The options are:
-l logging; write a debugging log to addr.log.
-n no authentication; respond to Tauth messages with an error (see attach(9P)).
-v verbose; more verbose when repeated
-A rewrite all attach messages to use aname and afid; used to implement srv(4)’s -a option
-c multiplex clients onto a single connection to addr, instead of standard input and output
-M do not initialize the connection with a Tversion message; instead assume 9P2000 and a maximum message size of msize
