next in thread | raw e-mail | index | archive | help
On my 4.0-stable system (last cvsup'd Mar 28), this is the end of
/etc/security (I broke the zcat line across two lines for this email):
echo "${host} login failures:"
zcat -f $LOG/messages.0* $LOG/messages | grep -i \
"^$yesterday.*login failure"
# Show tcp_wrapper warning messages
#
separator
echo "${host} refused connections:"
zcat -f $LOG/messages.0* $LOG/messages | grep -i \
"^$yesterday.*refused connect"
Shouldn't it be checking $LOG/messages instead of messages.0*? The
default newsyslog.conf on this system rotates /var/log/messages when it
hits 100k; maybe /etc/security is expecting it to be rotated daily.
I think the following would solve this:
echo "${host} login failures:"
if [ -f $LOG/messages ]; then
grep -i "^$yesterday.*login failure" $LOG/messages
if [ -f $LOG/messages.0* ]; then
zcat -f $LOG/messages.0* $LOG/messages | grep -i \
"^$yesterday.*login failure"
fi
else
echo "$LOG/messages does not exist!"
fi
# Show tcp_wrapper warning messages
#
separator
echo "${host} refused connections:"
if [ -f $LOG/messages ]; then
grep -i "^$yesterday.*refused connect" $LOG/messages
if [ -f $LOG/messages.0* ]; then
zcat -f $LOG/messages.0* $LOG/messages | grep -i \
"^$yesterday.*refused connect"
fi
else
echo "$LOG/messages does not exist!"
fi
Again, I split the zcat line for this email.
I guess I should probaby have done a PR on this, but I wasn't sure if
there was a good reason for the way things were setup that was escaping
me.
