9PSERVE(4) 9PSERVE(4)
NAME
9pserve - announce and multiplex 9P service
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 mul-
tiplexes 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 unexpect-
edly. On Unix, 9pserve takes the place of the Plan 9 ker-
nel, multiplexing clients onto a single server conversation
and cleaning up after clients when they hang up unexpect-
edly.
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 mes-
sage; instead assume 9P2000 and a maximum message size
of msize
