Make sure you don't think 'rm -rf /remailer-logs' actually destroys data. It merely de-allocates the i-nodes. You need to know which physical device the filesystem is on, (let's call id /hdxxx) and then do 'cat /dev/null > /dev/hdxxx' which overwrites with zeroes all data on that partition.
not quite. you need something like dd if=/dev/null of=/dev/xxx bs=verybig conv=sync this will zero out every block on the disk. but this is overkill -- why not just apply this technique to the individual logs, zeroing out their data blocks? peter ps: is it certain that zeroing out the data blocks thoroughly destroys the data? i've heard that a "shadow" of some sort may remain.
