The easiest thing is probably to find a friend with FTP access. If there is a Linux user's group near you, they may be able to help.

If you have a reasonably good email connection, you could try the FTP-by-mail servers at ftpmail@ftp.sunet.se, or ftpmail@ftp.uni-stuttgart.de.

Linux is also available via traditional mail on CD-ROM. The file ftp://metalab.unc.edu/pub/Linux/docs/HOWTO/Installation-HOWTO, and the file ftp://metalab.unc.edu/pub/Linux/docs/HOWTO/Distribution-HOWTO contain information on these distributions.
