==== Upgrading via Nbspupdate ====

Nbsp can be upgraded easily. The first thing is to install the
**nbspadm** package for your OS. That package contains the program
//nbspupdate// which is used as follows.

Executing

<code>
nbspupdate
</code>

without arguments, will check the version of the installed
Nbsp package against the latest one available, and if the latter
is newer than the former it will download it.
The Nbsp package can then be upgraded manually as usual.
Alternatively, executing

<code>
nbspupdate -u
</code>

will do the upgrade automatically after downloading the package as above.
Passing the **-F** option as well, i.e.,

<code>
nbspupdate -u -F
</code>

//nbspupdate// will do as above, even if the installed version
is the same as the latest one, or if Nbsp had not been installed before.
//nbspupdate// can also upgrade **npemwin** and **nbspadm** itself,
by passing any of those names as an argument; i.e.,

<code>
nbspupdate -u npemwin
</code>

will download and upgrade **Npemwin** if the latest version
is different than the installed one.

== NOTE ==

Starting with version 2.0.r2, **nbspd** and **npemwind** run
as the user //noaaport//, and therefore the directories where
the daemons write must be owned by that user:

<code>
    chown -R noaaport:noaaport /var/noaaport
    chown -R noaaport:noaaport /var/log/noaaport
    chown -R noaaport:noaaport /var/log/nbsp
    chown -R noaaport:noaaport /var/run/nbsp
</code>

During a fresh install, the package installer will create the 
directories with the appropriate ownership, but not during an upgrade.
If you are upgrading from an older version,
those commands must be executed manually.

The corresponding commands for **Npemwin** are
<code>
    chown -R noaaport:noaaport /var/npemwin
    chown -R noaaport:noaaport /var/log/npemwin
    chown -R noaaport:noaaport /var/run/npemwin
</code>
