It doesn't work very well on Windows Native CIFS shares from what my forensics friends have told me. > Is there some way or utility to wipe out all the data from unused space? > For the simplest level of 'wiping' you can try the following: make sure your samba share is its own physical partition seperate from say /var, etc. have a regular job that runs at off hours and does the following: dd if=/dev/zero of=/my/local/filesystem/zero_file when dd dies from lack of space remove /my/local/filesystem/zero_file It wont be DOD regs but it will give some level of cleanliness [where level is better than nothing, but not much.] Your big problem will be that this can/will cause problems with clients that are writing regular data to that disk. > Thanks, > > Mindaugas > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > -- Stephen J Smoogen. -- CSIRT/Linux System Administrator How far that little candle throws his beams!
