.SH DESCRIPTION
|
|
On Plan 9, when a user-level file server mounts itself into a name space
|
|
or posts itself in
|
|
.BR /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,
|
|
.I 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.
|
|
.PP
|
|
.I 9pserve
|
|
announces a 9P service on
|
|
.I addr
|
|
and multiplexes any 9P clients connecting to
|
|
.I addr
|
|
into a single conversation with a 9P server on
|
|
.IR 9pserve 's
|
|
standard input and output.
|
|
When a client hangs up,
|
|
.I 9pserve
|
|
flushes any outstanding 9P transactions
|
|
and clunks any outstanding fids belonging to the client.
|
|
.PP
|
|
.I 9pserve
|
|
is typically not invoked directly; use
|
|
.MR post9pservice (3)
|
|
instead.
|
|
.PP
|
|
The options are:
|
|
.TP
|
|
.B -l
|
|
logging; write a debugging log to
|
|
.IB addr .log \fR.
|
|
.TP
|
|
.B -n
|
|
no authentication; respond to Tauth
|
|
messages with an error (see
|
|
.IR attach (9P)).
|
|
.TP
|
|
.B -v
|
|
verbose; more verbose when repeated
|
|
.TP
|
|
.B -A
|
|
rewrite all attach messages to use
|
|
.I aname
|
|
and
|
|
.IR afid ;
|
|
used to implement
|
|
.MR srv (4) 's
|
|
.B -a
|
|
option
|
|
.TP
|
|
.B -c
|
|
multiplex clients onto a single connection to
|
|
.IR addr ,
|
|
instead of standard input and output
|
|
.TP
|
|
.B -M
|
|
do not initialize the connection with a
|
|
.B Tversion
|
|
message;
|
|
instead assume 9P2000 and a maximum message size of
|
|
.IR msize
