the -T test just tries using a variety of buffer sizes during the data transfer, followed by a cancel (instead of completing the scan) IIRC. This might put some scanners/backends into a funk, as they dont properly implement the cancel. i would not assume that every scanner/backend combination will act properly with -T. allan -- "The truth is an offense, but not a sin"
