Read and respond to this message at: https://sourceforge.net/forum/message.php?msg_id=6016706 By: lnxgnome 1) Enable SNMP read on the router in Configuration / Advanced / Device Management. The "read community" is your password. Optionally, set the IP to that of the machine running ddclient. 2) The machine running ddclient needs to have `snmpwalk` and `awk`. snmpwalk can be found as part of the net-snmp package. 3) Add this to your ddclient.conf: use=cmd, cmd="/usr/local/bin/get_external_ip_from_router internal_hostname_or_IP_of_router" 4) Create the script file /usr/local/bin/get_external_ip_from_router and make it executable. It should look like this: #!/bin/bash if [ "$1" == "" ]; then exit 99 else GW=$1 EXTIF=`snmpwalk -Ov -Oq -c public -v 1 $GW ipRouteIfIndex.0.0.0.0` ENTRY=`snmpwalk -Os -Oq -c public -v 1 $GW ipAdEntIfIndex | awk '$2=='$EXTIF' { print $1 }'` IP=${ENTRY/ipAdEntIfIndex./} echo $IP fi 5) test the script by running it from the commandline: /usr/local/bin/get_external_ip_from_router internal_hostname_or_IP_of_router example: # /usr/local/bin/get_external_ip_from_router 192.168.1.1 221.221.123.101 If the script does not work, do you have a default/0.0.0.0 route to ipwan? (it keys off of that) 6) stop/start ddclient --LnxGnome ______________________________________________________________________ You are receiving this email because you elected to monitor this forum.
