Ok here I am again.. Well I downloaded and installed the network-manager-pptp package. It also needed to download the pkgtool2 package because as you know .deb files are not supported by slackware. (pkgtool2 converts and installs .deb package in slackware.) Anyway, while I tried to run the network-manager-pptp from GUI it didn't come up. So I tried through bash and I got this error:
/usr/bin/nm-ppp-starter: cannot execute binary files.
So I suppose that slackware, though installed the package is unable to open it because it contains binary files... Any suggestions on this problem please?
Thanks in advance,
