| <p><font size=+1><b>DESCRIPTION </b></font><br> |
| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> |
| |
| <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> |
