Hi,
i have made up a IP Table for Blocking some incoming IP's as one of my users was hacked however after entering some IP's after Reboot they are saved but when i enter a new IP it overwrites all of the old entries where am i going wrong?
Here is my config:
I used a script in the following location /etc/network/if-pre-up.d/iptables
This script is:
#!/bin/sh
# Load iptables rules before interfaces are brought online
# This ensures that we are always protected by the firewall
#
# Note: if bad rules are inadvertently (or purposely) saved it could block
# access to the server except via the serial tty interface.
#
RESTORE=/sbin/iptables-restore
STAT=/usr/bin/stat
IPSTATE=/etc/iptables.conf
test -x $RESTORE || exit 0
test -x $STAT || exit 0
# Check permissions and ownership (rw------- for root)
if test `$STAT --format="%a" $IPSTATE` -ne "600"; then
echo "Permissions for $IPSTATE must be 600 (rw-------)"
exit 0
fi
# Since only the owner can read/write to the file, we can trust that it is
# secure. We need not worry about group permissions since they should be
# zeroed per our previous check; but we must make sure root owns it.
if test `$STAT --format="%u" $IPSTATE` -ne "0"; then
echo "The superuser must have ownership for $IPSTATE (uid 0)"
exit 0
fi
# Now we are ready to restore the tables
$RESTORE < $IPSTATE
when i save an entry i do the following:
iptables-save > /etc/iptables.up.rules
as stated earlier after reboot old entries are in the iptables.up.rules
but when a new entry is saved the old are wiped?
Thanks
