import(4) - Plan 9 from User Space

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