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

(http://osuosl.org) for donating additional FTP and rsync hosting

to the Slackware project! 🙂

Also see the “Get Slack” section on http://slackware.com for

additional mirror sites near you.
