#Al the directiory locations wil be mentinedin the first

# Trace output function
trace ()
{
if [ $TRACE ]
then
DATE=`date +"%Y-%m-%d %X"`
echo "$DATE: $1" >> $TRACEFILE
fi
}

trace "Script $0 started"

# First find all alarm files to import at start
FILES="`find $ALARM_FILES_DIR -type f`"

# Loop forever and import files
while [ true ]
do
loop=`expr $loop + 1`

# cat the files to a text file
if [ "$FILES" != "" ]
then
FILES_SORTED="`ls -rt $FILES`"
trace "Alarm files to import:\n$FILES_SORTED"

for i in $FILES_SORTED
do
cat $i>export1.txt

username=***
password=***

expect -c "
# exp_internal 1 # uncomment for debugging

LATEST="$i"
SENDHB=false

pam-script

PAM-SCRIPT(7)						 Miscellaneous Information Manual					     PAM-SCRIPT(7)

NAME

       pam-script - a PAM module that can invoke scripts within the PAM stack.

SYNOPSIS

       pam-script.so [onerr=(success|fail)][dir=/some/path/]

DESCRIPTION

       pam-script allows you to execute scripts during authorization, passwd changes, and on session opening or closing.

       Such  scripts  can  perform necessary tasks or influence the outcome of the PAM stack.  For example, if the following entry was included in
       pam.conf
	 sshd	 auth required	pam_script

       then if the script, pam_script_auth, exits with a non-zero value this would cause the user to be denied SSH access to the machine.

OPTIONS

       A summary of options is included below.

       onerr=(success|fail)
	      the default behavior if the module can not find or execute the script.  The default is to fail if the option is not given.

       dir=/some/path/
	      where to find the pam-scripts to invoke for each of the various module-types as described below.	The default is dir=/usr/share/lib-
	      pam-script if not given.

	      List of scripts

       pam_script_auth
	      Executed under auth which handles the authentication stage of establishing the user via some challenge-response (i.e. username/pass-
	      word)

       pam_script_acct
	      invoked under account module-type for non-authentication based account management.

       pam_script_passwd
	      invoked under passwd for changing the password tokens.

       pam_script_ses_open
	      invoked when a session is first opened.

       pam_script_ses_close
	      run after a session is first closed.

	      All the scripts will be passed several environment variables: PAM_USER, PAM_RUSER, PAM_RHOST, PAM_SERVICE, PAM_AUTHTOK, PAM_TTY, and
	      PAM_TYPE referring to the module-type.  The pam_script.so arguments in the pam.conf will be passed on the command line, which can be
	      used to modify the script behavior.

FILES

       /lib/security/pam_script.so - the PAM module
       /usr/share/libpam-script - where the scripts should be placed by default

VERSION

       pam-script 1.1.5
