# check_root - 05/30/99
#
# 03/31/2005 jfs - Fixed call to grep
# 04/03/2004 rbrad - Fixed a bug with the PermitRootLogin ssh check where the
# check failed if PermitRootLogin was both present and commented out.
# 11/16/2003 jfs Applied patch from Nicolas François to work non-interactively
# even in SuSE (broken in previous patch) This problem has also
# been reported multiple times in Debian: #218056, #220924
# 10/19/2003 jfs Applied patch from Ryan Bradetich which fixes mesg check
# in SuSE. Also fixed message on root logins in SSHD
# 09/19/2003 jfs Applied patch from Nicolas François in order to properly
# work non-interactively (MESG complains if not running in a tty)
# 09/03/2003 jfs Use SSHD_CONFIG instead of SSHCONF
# 08/28/2003 jfs Fixed syntax error
# 08/14/2003 jfs Implemented some of ARSC changes done in Tara 3.0.3,
# including a bugfix and checks for SSH PermitRootLogin's
# (although changes have been implemented to allow for OS
# and site configuration of the SSHD_CONFIG file location)
# 05/26/2003 jfs Fixed calls to test (worked in Linux but not in other OS due
# to -n not being implicit)
# 07/25/2002 jfs Changed TigerInstallDir to .
# 05/30/1999 Added feature to check for no console root logins
