.TH "\fBotp-control\fP" "1"
.SH "NAME"
\fBotp-control\fP \(em Local user database configuration for One Time Password package\&.
.SH "SYNOPSIS"
.PP
\fBotp-control\fP [-?hnv]  [-c\fI count\fP]  [-C\fI count_ceiling\fP]  [-f\fI format\fP]  [-F\fI flag\fP]  [-H\fI sc_hostname\fP]  [-I\fI sc_index\fP]  [-k\fI key\fP]  [-l\fI location\fP]  [-m\fI command_mode\fP]  [-o\fI otp_db\fP]  [-s\fI status\fP]  [-S\fI sc_flags\fP]  [-t\fI type\fP]  [-u\fI username\fP]  [-V\fI service_name\fP]  [-w\fI window\fP] 
.SH "DESCRIPTION"
.PP
The \fBotp-control\fP command is a front end to the
local One Time Password database\&.  Users can be added, modified
and removed by \fBotp-control\&.\fP
.SH "OPTIONS"
.IP "-c, --count= \fI count\fP" 10
User count\&.  The count increases with each OTP transaction\&.
.IP "-C, --count-ceil= \fI count_ceiling\fP" 10
User count ceiling\&.  Highest count allowed for this user\&.  Configuring
the count_ceiling allows a user key to be shared among multiple
systems each with a unique count window, where count <= count_ceiling\&.
.IP "" 10
A count value must only be allowed for authentication once\&.
.IP "" 10
Example:
.IP "" 10
host=h1, user=bob, count_current=0, count_ceiling=10000\&.
.IP "" 10
host=h2, user=bob, count_current=10001, count_ceiling=20000\&.
.IP "" 10
The number of keys a user must possess is decreased at the expense
of security dependencies among multiple systems\&.  If system A is
compromised, OTP\&'s can be generated for the user(s) on system B from
the shared keys on system A\&.  To generate an OTP out of sequence the count
must be presented to the OTP generator\&.  The additional step of entering
the count to the OTP generator is not necessary when keys are not
shared, as the currrent count will increase on the OTP generator and
system database during authentication\&.
.IP "-f, --format=" 10
OTP format\&.  One of hex40 dhex40 dec31\&.6 dec31\&.7 dec31\&.8 dec31\&.9 dec31\&.10\&.
hex40 (40 bit hex) is the default\&.  dec31\&.6 (31 bit decimal truncated to 6
digits) is suggested by RFC 4226 and may be required to interoperate with
other HOTP implementations\&.  dhex40 uses the dynamic truncate function
in RFC 4226, where hex40 always uses the top 40 bits\&.  dhex40 may be the
default in future releases\&.
.IP "-F, --flag=" 10
OTP flag\&.  All flags are unset by default\&.
.PP
.nf
   Flag              Description
   -----------------------------------------------------------------
   display-count  :  Display HOTP count when prompted for challenge\&.
   send-token     :  Send token to user out of band\&.
.fi
.IP "-h, --help" 10
Help\&.
.IP "-H, --sc_hostname=\fI sc_hostname\fP" 10
Set the SC hostname for the list-sc command mode\&.
.IP "-I, --sc_index=\fI sc_index\fP" 10
Set the SC index for the list-sc command mode\&.
.IP "-k, --key=\fI key\fP" 10
160 bit shared secret key in ASCII HEX\&.  The secret key is shared between
the OTP generation hardware/software for a user and the local OTP database\&.
Each user typically will have a unique key unless a shared key with
unique count space is provisioned\&.  Use - for stdin\&.  Example key:
C0C3D47F1CC68ECE0DF81D008F0C0D72D43EB745
.IP "-l, --location=\fI location\fP" 10
Location to send token to when SEND_TOKEN flag is set\&.
.IP "-m, --command_mode=\fI command_mode\fP" 10
.PP
.nf
            Mode             Description

            set-count-ceil     - Set user count ceiling
            set-flags          - Set user flags
            set-format         - Set user format
            set-status         - Set user status
            set-type           - Set user OTP type
            test               - Test user
.fi
.IP "-n, --create_database" 10
Create new database if one does not exist\&.
.IP "-o, --otp-db=\fI otp_db\fP" 10
Pathname of OTP database\&.
.IP "-s, --status=\fI status\fP" 10
OTP Status\&.  The default status is active\&.
.PP
.nf
   Status     Description
   -----------------------------------------------------------------
   active   : OTP is required for succesful authentication\&.
   inactive : OTP may not be required for successful authentication\&.
              The OTP authentication module may be configured to allow
              inactive accounts to authenticate\&.  This may be used to
              temporarily remove the OTP authentication method for a
              user\&.
   disabled : Account is disabled\&.  OTP authentication will fail\&.
.fi
.IP "-S, --sc-flags=\fI sc_flags\fP" 10
Set the SC flags for the list-sc command mode\&.  0=CHALLENGE, 1=READERKEY\&.
.IP "-t, --type=\fI type\fP" 10
OTP Type\&.  RFC 4226 HOTP is only supported type\&.
.IP "-u, --username=\fI username\fP" 10
Username to perform database operation on\&.
.IP "-v, --verbose" 10
Enable verbose output (debugging)\&.
.IP "-V, --service-name=\fI service_name\fP" 10
Set service name for send-token function\&.
.IP "--version" 10
Display software version\&.
.IP "-w, --challenge-window=\fI window\fP" 10
Set the maximum window (count above the system count) where an OTP
will successfully authenticate\&.  For user bob with with OTP generator
count_current=30, and system OTP database for bob count_current 15, the
default window (10) will not allow the user to authenticate, even though
the OTP is computed with a valid shared key\&.  This can be caused by the
user repeatedly generating an OTP which is not used for authentication\&.
.IP "" 10
When generating an OTP (mode generate) the window will configure the number
of tokens generated\&.
