u-pathname-filter
The server can be configured to disallow operations involving what it considers
to
be illegal pathnames. A pathname is considered illegal if it
contains non-printing
characters, spaces, or begin with a period. For anonymous users,
this feature is
controlled by a-pathname-filter; for non-anonymous users,
it is controlled by
u-pathname-filter.
Non-anonymous users often need to upload dot-files to their home directory
(.cshrc, .profile, .signature, etc.), so you
should avoid turning on u-pathname-filter.
Examples:
u-pathname-filter=no
u-pathname-filter=yes
