.SH NAME
skeysh \-  Authentication shell used for S/Key challenges.
.SH SYNOPSIS
.B skeysh
.SH DESCRIPTION
.I skeysh
is used as the shell of a shared "skey" user account (specified in /etc/passwd) 
for S/Key-authenticating any S/Key user upon login.  S/Key access through the 
skey user and skeysh is used when the S/Key login program (e.g. logdaemon) 
can not be used.  Skeysh can be viewed as a reasonably secure alternative to 
building an S/Key-aware logdaemon.

.SH AUTHORS
The skeysh authentication shell for S/Key 2.2 was written by 
Michael Holst <mholst@math.ucsd.edu>, based heavily on keysh for S/Key 1.1c,
written by Phil Karn, Neil M. Haller, John S. Walden, and Scott Chasin.
The original keysh was not a complete logdaemon replacement like skeysh,
since it did not support the specification of the username on login, and it 
did not identify the correct shell after a successful S/Key authentication.
This limited the keysh for use as an individual user's login shell.
