Hello,
I''m using shorewall-4.5.16 with centos5. The dhclient stores the lease
information on
the /var/lib/dhclient/dhclient-<DEVICE>.leases file.
The /var/lib/shorewall/firewall script has the function detect_dynamic_gateway
that
detects the gateway based on the leases file. The code in the function is:
detect_dynamic_gateway() { # $1 = interface
local interface
interface=$1
local GATEWAYS
GATEWAYS local gateway
gateway=$(run_findgw_exit $1);
if [ -z "$gateway" ]; then
gateway=$( find_peer $($IP addr list $interface ) )
fi
if [ -z "$gateway" -a -f ${VARLIB}/dhcpcd/dhcpcd-${1}.info ]; then
eval $(grep ^GATEWAYS= ${VARLIB}/dhcpcd/dhcpcd-${1}.info 2>
/dev/null)
[ -n "$GATEWAYS" ] && GATEWAYS=${GATEWAYS%,*}
&& gateway=$GATEWAYS
fi
if [ -z "$gateway" -a -f ${VARLIB}/dhcp/dhclient-${0}.lease ];
then
gateway=$(grep ''option routers''
${VARLIB}/dhcp/dhclient-${1}.lease | tail -n 1 |
while read j1 j2 gateway; do echo $gateway ; return 0; done)
fi
[ -n "$gateway" ] && echo $gateway
}
How do you have the lease file in there? Is it only for some linux distro, say
ubuntu?
In centos is hardcoded to another directory:
root localhost /etc/sysconfig/network-scripts # grep DHCLIENTARGS ifup-eth
DHCLIENTARGS="${DHCLIENTARGS} ${ONESHOT} -q ${DHCLIENTCONF} -lf
/var/lib/dhclient/dhclient-${DEVICE}.leases -pf
/var/run/dhclient-${DEVICE}.pid"
The attached patch correct this issue. Can you please import it?
Thanks,
Nuno Fernandes
