Where Find New Packages
HINT: Getting slow download speeds from ftp.slackware.com?
Give slackware.osuosl.org a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading
directly from ftp.slackware.com.
Thanks to the friendly folks at the OSU Open Source Lab
(https://osuosl.org/) for donating additional FTP and rsync hosting
to the Slackware project! :-)
Also see the "Get Slack" section on http://www.slackware.com/ for
additional mirror sites near you.

Installation Instructions
Installation instructions: Upgrade the kernel packages as root and reinstall LILO. If you are building your own kernel from unfixed vanilla sources, the patch(es) appropriate for your kernel may be applied to the source like this: cd /usr/src/linux zcat linux-2.6.29.6-03-ip_fragment-CVE-2009-1298.diff.gz | patch -p1 --verbose Note that the previous security patches should also be applied if using unfixed 2.6.29.6 sources. Those are also available in the same directory on the FTP server.
