.SH ACTIONS

\fBadd_hmac_chalresp\fR
|
|
The PAM module can utilize the HMAC-SHA1 Challenge-Response mode found in YubiKeys
|
|
starting with version 2.2 for \fBoffline authentication\fR. This action creates the initial state
|
|
information with the C/R to be issued at the next logon.
|
|
|
|
The utility currently outputs the state information to a file in the current user's
|
|
home directory (\fI~/.yubico/challenge-123456\fR for a YubiKey with serial number API readout
|
|
enabled, and \fI~/.yubico/challenge\fR for one without).
|
|
|
|
The PAM module supports a system wide directory for these state files (in case the user's
|
|
home directories are encrypted), but in a system wide directory, the 'challenge' part should
|
|
be replaced with the username. Example : \fI/var/yubico/challenges/alice-123456\fR.
|
|
|
|
To use the system-wide mode, you currently have to move the generated state files manually and
|
|
configure the PAM module accordingly.
|
|
|
|
.SH EXAMPLE
|
|
First, program a YubiKey for challenge response on Slot 2 :
|
|
.HP
|
|
.nf
|
|
$ \fBykpersonalize \-2 \-ochal-resp \-ochal-hmac \-ohmac-lt64 \-oserial-api-visible\fR
|
|
...
|
|
Commit? (y/n) [n]: y
|
|
$
|
|
.fi
|
|
.HP
|
|
Now, set the current user to require this YubiKey for logon :
|
|
.HP
|
|
.nf
|
|
$ \fBykpamcfg \-2 \-v\fR
|
|
...
|
|
Stored initial challenge and expected response in '/home/alice/.yubico/challenge-123456'.
|
|
$
|
|
.fi
|
|
.HP
|
|
Then, configure authentication with PAM for example like this (\fImake a backup first\fR) :
|
|
.HP
|
|
\fI/etc/pam.d/common-auth\fR (from Ubuntu 10.10) :
|
|
|
|
.nf
|
|
auth required pam_unix.so nullok_secure try_first_pass
|
|
auth [success=1 new_authtok_reqd=ok ignore=ignore default=die] pam_yubico.so mode=challenge-response
|
|
auth requisite pam_deny.so
|
|
auth required pam_permit.so
|
|
auth optional pam_ecryptfs.so unwrap
|
|
.fi
