If you are trying to install rp-pppoe into your box, I would sugges you get the one supplied with Slackware's
extra directory (see sample
link);
Once you copy it to a floppy, you should be able to mount the floppy with the default installation of slackware by issuing the command at the command line prompt:
mount -t msdos /dev/fd0h1440 /mnt/floppy (assuming you have the mount point 'floppy' under /mnt);
Then just copy the tgz file to your tmp directory (i.e.
copy /mnt/floppy/rp-pppoe-X-Y-i386-Z.tgz /tmp
and install it (i.e.
installpkg /tmp/rp-pppoe-X-Y-i386-Z.tgz )
once you install it you need to configure it. And to do that you run the setup script under
/usr/sbin/adsl-setup (I believe that is the location of it).
If the location of the script is under /usr/sbin, then you would do the following at the command prompt:
/usr/sbin/adsl-setup
From that point on, you just answer the questions is prompts you with, and then just make sure your NIC works and your modem is connected, before running the
adsl-start script.
