# Note: You MUST have rsync 2.0.16-1 or newer, which is available in slink
# and all newer Debian releases, or at http://rsync.samba.org/

# Set the variables below to fit your site. You can then use cron to have
# this script run daily to automatically update your copy of the archive.

# Don't forget:
# chmod 744 anonftpsync

# TO is the destination for the base of the Debian mirror directory
# (the dir that holds dists/ and ls-lR).
# (mandatory)

TO=/home/foo/rsync-debian-ports

# RSYNC_HOST is the site you have chosen from the mirrors file.
# (http://www.debian-ports.org/mirrors)
# (mandatory)

RSYNC_HOST=rsync.debian-ports.org

# RSYNC_DIR is the directory given in the "Packages over rsync:" line of
# the mirrors file for the site you have chosen to mirror.
# (mandatory)

RSYNC_DIR=debian/

# LOGDIR is the directory where the logs will be written to
# (mandatory)

LOGDIR=/var/log/rsync-debian-ports

# ARCH_EXCLUDE can be used to exclude a complete architecture from
# mirrorring. Please use as space seperated list.
# Possible values are:
# armel hurd-i386 kfreebsd-amd64 kfreebsd-i386
#
# There is one special value: source
# This is not an architecture but will exclude all source code in /pool
#
# eg.
# ARCH_EXCLUDE="hurd-i386"
# 
# With a blank ARCH_EXCLUDE you will mirror all availible architectures
# (optional)

ARCH_EXCLUDE="armel kfreebsd-amd64 kfreebsd-i386 m68k"

# EXCLUDE is a list of parameters listing patterns that rsync will exclude.
# The following example would exclude mostly everything:
#EXCLUDE="\
#  --exclude binary-hurd-i386/ --exclude binary-kfreebsd-i386/
#  --exclude *_hurd-i386.deb --exclude *_knetbsd-i386.deb \
#  --exclude stable/ --exclude testing/ --exclude unstable/ \
#  --exclude source/ \
#  --exclude *.orig.tar.gz --exclude *.diff.gz --exclude *.dsc \
#  --exclude /base/ --exclude /bochs/ --exclude /obsolete/ \
# "

# With a blank EXCLUDE you will mirror the entire archive.
# (optional)

EXCLUDE="--exclude binary-kfreebsd-i386/ --exclude *_knetbsd-i386.deb \
         --exclude source/ --exclude *.orig.tar.gz --exclude *.diff.gz \
         --exclude /bochs/ --exclude /obsolete/ \
         --exclude *kfreebsd* --exclude *m68* --exclude *sh* \
	 "

# MAILTO is the address to send logfiles to;
# if it is not defined, no mail will be sent
# (optional)

# are problems.

Run it using:

    sudo sh anonftpsync-ports

In /home/foo/rsync-debian-ports, you will find the following directories:
