Hi Dominic,
Thanks for sharing your solution.
That got me thinking, your solution has some similarities to how the dynamic
DNS client "ddclient" works.
It seems ddclient has a "postscript" option where an external script can be
called on an IP update, and additionally the script is called with "$1" set to
the new IP address.
So, if anyone is interested I'll throw out this *untested* alternative...
--
# copy the default general ddclient.conf to an editable place
cp /stat/etc/ddclient.conf /mnt/kd/ddclient.conf
#
# edit /mnt/kd/ddclient.conf and add this line at the top
postscript=/mnt/kd/bin/ddclient-action
#
# create the script "/mnt/kd/bin/ddclient-action"
====
#!/bin/sh
if [ -n "$1" ]; then
sed -i -e "s/^externip *=.*/externip=$1/" /etc/asterisk/sip.conf
asterisk -rx "sip reload"
logger -t ddclient-action -p kern.info "Asterisk SIP reload on ddclient
update to: $1"
fi
====
# make it executable
chmod 755 /mnt/kd/bin/ddclient-action
#
# Using the Network tab -> Dynamic DNS Update: [ ddclient ] - configure for
your provider
# { Reboot/Restart } - [ Restart Dynamic DNS ] - x Confirm
--
Again, this is untested.
