Well I grabbed planet-110810.osm.bz2 from planet.openstreetmap.org

but i still cannot extract the osm file from bz2 or get an md5sum…

$ md5sum -c planet-110810.osm.bz2.md5
planet-110810.osm.bz2: FAILED
md5sum: WARNING: 1 of 1 computed checksum did NOT match

it seems im doing something wrong procedurally to get a corrupt file every time.
