NAME
pamusb-check - simulates pam_usb authentication SYNOPSIS
Usage: pamusb-check [--help] [--debug] [--config=path] [--service=name] [--dump] [--quiet] <username> DESCRIPTION
pamusb-check can simulate authentication through the pam_usb engine. It is useful for both testing purposes (to check the pam_usb configu- ration without having to try with a real program), but also for scripting. pamusb-check's exit code is 0 if the authentication was success- ful, 1 otherwise. It is used by pamusb-agent to check the device. EXAMPLES
$ pamusb-check scox o Authentication request for user "scox" (pamusb-check) o Device "creative" is connected (good). o Access granted. $ pamusb-check --service=su scox o Authentication request for user "scox" (su) o Device "creative" is connected (good). o Access granted. $ pamusb-check --dump scox Configuration dump for user scox (service: pamusb-check): enable : true debug : false quiet : false color_log : true one_time_pad : true probe_timeout : 10 hostname : helium system_pad_directory : .pamusb device_pad_directory : .pamusb OPTIONS
--help, -h Show summary of options. --debug, -D Shows debug messages. --config, -c Use the given configuration file (defaults to /etc/pamusb.conf). --service, -s Service name to be used for authentication (defaults to pamusb-check) --dump, -d Dump the configuration, but do not try to authenticate --quiet, -q Quiet mode BUGS
Please send bug reports to the pam_usb mailing list. AUTHOR
