For ECI driver, we do this way on IPCop
First
if [ "$PROTOCOL" = "RFC1483" ]; then
case "$ENCAP" in
0) ECIMODE="LLC_SNAP_RFC1483_BRIDGED_ETH_NO_FCS"
;;
1) ECIMODE="VCM_RFC_1483_BRIDGED_ETH"
;;
2) ECIMODE="LLC_RFC1483_ROUTED_IP"
;;
3) ECIMODE="VCM_RFC1483_ROUTED_IP"
;;
*) msg "Unknown encapsulation: $ENCAP"
exit 1
;;
esac
# Start pppoeci
if [ "$ENCAP" = "0" -o "$ENCAP" = "1" ]; then
ECIIF="tap0"
else
ECIIF="tun0"
fi
/sbin/insmod tun
/usr/bin/pppoeci -alt 4 -vpi $VPI -vci $VCI -vendor 0x$VID2 -product
0x$PID2 -mode $ECIMODE
wait_for_iface $ECIIF
/sbin/ifconfig $ECIIF up
exit $?
fi
and secondly (perl script)
} elsif ($pppsettings{'METHOD'} eq 'STATIC') {
my @staticcommand = ('/sbin/ifconfig');
push(@staticcommand, ($iface, $pppsettings{'IP'},'netmask',
$pppsettings{'NETMASK'}));
if ($pppsettings{'BROADCAST'} ne '') {
push(@staticcommand, ('broadcast', $pppsettings{'BROADCAST'}));
}
system (@staticcommand);
system ("/sbin/route","add","default","gw",$pppsettings{'GATEWAY'});
system ("/bin/touch", "${swroot}/red/active");
system ("/etc/rc.d/rc.updatered");
exit 0;
You may have another problem and this is the reason I show you the static
METHOD part.
TUN interface may not be supported by you dhcp client. It is not supported
by dhcpcd v1.3.22-pl4
