If you wish to mirror the mktemp distribution, please mirror the master site, ftp://ftp.mktemp.ws/pub/mktemp. The best times to mirror are between midnight and 8am US mountain standard time (MST).
In addition to standard ftp-based mirroring, you may also mirror the ftp site via rsync. To mirror the ftp site via rsync, run something like
rsync -avz rsync.mktemp.org::mktemp_ftp /path/to/your/mirror
rsync -avz rsync.mktemp.org::mktemp_www /path/to/your/mirror
Note that this will not mirror the dist subdirectory since this should simply be a link to the ftp site (or a mirror thereof).
