Putting all FTP uploads to /dev/null

[RichardReed]

I have installed Ubuntu 6.06 server with vsftpd installed. The server is being used for EVDO network performance testing at my job. We use FTP to download and upload to determine the avg speeds.

Now my question is, i would like to put all uploaded files to be directed to /dev/null . Currently I am using cron job to delete all left over files in upload folder nightly. It would only be linked to specified user for that.. All other users have normal upload behaviors.

I am willing to try different FTP daemon if needed (ie. proftpd) to meet the requirement i am seeking.

Thanks,
Richard
