# This script can be used together with the virtual_imgdev to simulate an
|
|
# image based fingerprint reader.
|
|
#
|
|
# To use, set the FP_VIRTUAL_IMAGE environment variable for both the
|
|
# libfprint using program (e.g. fprintd) and this script.
|
|
#
|
|
# Usually this would work by adding it into the systemd unit file. The
|
|
# best way of doing so is to create
|
|
# /etc/systemd/system/fprintd.service.d/fprintd-test.conf
|
|
#
|
|
# [Service]
|
|
# RuntimeDirectory=fprint
|
|
# Environment=FP_VIRTUAL_DEVICE=/run/fprint/virtdev_sock
|
|
# Environment=G_MESSAGES_DEBUG=all
|
|
# ReadWritePaths=$RUNTIME_DIR
|
|
#
|
|
# After that run:
|
|
#
|
|
# systemctl daemon-reload
|
|
# systemctl restart fprintd.service
|
|
#
|
|
# You may also need to disable selinux.
|
|
#
|
|
# Then run this script with e.g.
|
|
# FP_VIRTUAL_DEVICE=/run/fprint/virtdev_sock ./sendvirtimg.py "ADD <username> <finger> <success|failure>"
