OK, the behavior is related to a silly copy/paste error. This command is working as expected:
$ wget -c -r -np --user d9-workgrps --password Private15 "ftp://medical.nema.org/MEDICAL/Private/Dicom/WORKGRPS/Wg06/"; But this one should trigger a segfault in approx 1 minute (notice the double slash '//'): $ wget -c -r -np --user d9-workgrps --password Private15 "ftp://medical.nema.org//MEDICAL/Private/Dicom/WORKGRPS/Wg06/"; not sure what the ftp spec says about double slash in URLs.
