Dear Philipp,
Hello,

The Links which you have been posted on above post give the following error

Forbidden
You don't have permission to access /pub/linux/suse/ftp.suse.com/suse/i386/9.2/iso/SUSE-Linux-9.2-FTP-DVD.iso on this server.

Apache/1.3.27 Server at ftp.gwdg.de Port 80

I think the Original Link for Suse 9.2 DVD ISO is ftp://ftp.suse.com/pub/suse/i386/9.2/iso/

Best Regards.
