Keeping a Slackware Linux Server up-to-date
There are many methods you can use to upgrade Slackware packages, I detail how to use Swaret Here, but you don't need to use any 3rd-part tool to keep your Slackware system up-to-date. Here's how I do it...
Check for packages that need updating
Upgrading the package
The advisory will give you information on why the package needs to be updated, and where to get it, for example:
A grayscale PNG image with a malformed (bad CRC) tRNS chunk will crash some libpng applications. This vulnerability has been assigned the identifiers CVE-2007-2445 and CERT VU#684664. For more information, see: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2445 (* Security fix *) Updated package for Slackware 10.2: ftp://ftp.slackware.com/pub/slackware/slackware-10.2/patches/packages/libpng-1.2.18-i486-1_slack10.2.tgz
To get the package, you can use
wget and the url provided, for example:
Then read the advisory further, and it will give advice on how to upgrade the package, for example:
Upgrade the packages as root: # upgradepkg libpng-1.2.18-i486-1_slack11.0.tgz
By running that
upgradepkg command, you will now have updated your package. Sometimes there are further instructions on restarting services etc.
