SKEYSH(1)

NAME
skeysh - S/Key login shell

SYNOPSIS
/usr/etc/skeysh [username]

DESCRIPTION
skeysh is a solution for sites that cannot replace the login program. Instead, one sets up an unprivileged dummy account with skeysh as its login shell.

A user first logs into the S/Key dummy account. skeysh then prompts for the user's real account name and presents the corresponding S/Key challenge. When the user produces the correct responses, the program invokes the user's login shell after performing user-specific activities: updating of environment variables; updating of the lastlogin, wtmp and utmp files; looking at the motd and mail files.
