|

|
|
<i>Import</i> presents the 9P service <i>service</i> (default <tt><font size=+1>plumb</font></tt>) running
|
|
on <i>system</i> as a service on the local system, in the current name
|
|
space.
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
The <tt><font size=+1>−n</font></tt> option sets the remote name space directory where <i>import</i>
|
|
should expect to find <i>service</i>. If it is not specified, <i>import</i>
|
|
uses name of the local system’s name space directory. (Since name
|
|
space directories are conventionally inside <tt><font size=+1>/tmp</font></tt>, the path have
|
|
different meanings on the two systems.)
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
<i>Import</i> connects to <i>system</i> using <a href="../man1/ssh.html"><i>ssh</i>(1)</a>. It invokes <i>import</i> on the
|
|
remote system to carry out the remote side of the protocol. The
|
|
<tt><font size=+1>−p</font></tt> option specifies the path to <i>import</i> on the remote system, in
|
|
case it is not in the system search path.
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
The <tt><font size=+1>−d</font></tt> option turns on debugging. The <tt><font size=+1>−f</font></tt> option keeps <i>import</i> from
|
|
forking itself into the background, also useful for debugging.<br>

<p><font size=+1><b>EXAMPLE </b></font><br>
|
|
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
|
|
|
|
Suppose you run <tt><font size=+1>sam −r</font></tt> to the CPU server <i>anna</i>. <i>Sam</i> wants to talk
|
|
to a plumber on the local terminal, but the file names will refer
|
|
to files on <i>anna</i>.
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
To fix this problem, create a new name space directory and start
|
|
a new plumber on <i>anna</i>:<br>
|
|
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
|
|
|
|
<tt><font size=+1>remotens=/tmp/ns.`whoami`.on.`hostname`<br>
|
|
ssh anna mkdir $remotens<br>
|
|
ssh anna NAMESPACE=$remotens plumber<br>
|
|
</font></tt>Now import that plumber to the local name space before starting
|
|
<i>sam</i> and <i>9term</i>:<br>
|
|
<tt><font size=+1>NAMESPACE=/tmp/ns.anna<br>
|
|
mkdir $NAMESPACE<br>
|
|
import −n $remotens −s plumb anna<br>
|
|
sam &<br>

9term ssh anna &<br>
