.TH IMPORT 4
.SH NAME
import \- import 9P resources from another system
.SH SYNOPSIS
.B import
[
.B -dfx
]
[
.B -n
.I ns
]
[
.B -p
.I prog
]
[
.B -s
.I service
]
.I system
.SH DESCRIPTION
.I Import
presents the 9P service
.I service
(default
.BR plumb )
running on
.I system
as a service on the local system,
in the current name space.
.PP
The
.B -n
option sets the remote name space directory
where
.I import
should expect to find
.IR service .
If it is not specified,
.I import
uses name of the local system's name space directory.
(Since name space directories are conventionally inside
.BR /tmp ,
the path have different meanings on the two systems.)
.PP
.I Import
connects to
.I system
using
.MR ssh (1) .
It invokes
.I import
on the remote system to carry out the remote
side of the protocol.
The
.B -p
option specifies the path to
.I import
on the remote system, in case it is not in the system search path.
.PP
The
.B -d
option turns on debugging.
The
.B -f
option keeps
.I import
from forking itself into the background, also useful for debugging.
.PP
The
.B -x
option reverses the roles of the two machines,
exporting the service to, instead of importing it from,
the remote system.
.SH EXAMPLE
Suppose you run
.B sam
.B -r
to the CPU server
.IR anna .
.I Sam
wants to talk to a plumber on the local terminal,
but the file names will refer to files on
.IR anna .
.PP
To fix this problem, create a new name space directory
and start a new plumber on
.IR anna :
.IP
.EX
remotens=/tmp/ns.`whoami`.on.`hostname`
ssh anna mkdir $remotens
ssh anna NAMESPACE=$remotens plumber
.EE
.LP
Now import that plumber to the local name space before starting
.I sam
and
.IR 9term :
.IP
.EX
NAMESPACE=/tmp/ns.anna
mkdir $NAMESPACE
import -n $remotens -s plumb anna
sam &
9term ssh anna &
.EE
