dyndns update behind secound firewall
« on: October 05, 2004, 02:10:56 PM »
Hi

I have SME server configured as below

adsl ->firewall/router/wireless ->(internet cafe) ->DMZ(sme server -> Office network ->ip web cam)

Can see out no problem

My problem is How to keep dyndns updated preferable using the sme server

the build in dyndns updater just uses the external ip address which in this case isn't right

I'm not sure what you mean by "external ip address isn't right" ... you mean (internet cafe)-IP isn't correct external IP?!

Anyway:
Updating dyndns.org is essentially a very easy process...

If you just fill in the 4 Variables below
(note 3, DOMAIN,USERID,PASSWD, are actually constants)
you can execute the script once every ip change...

Code: [Select]
#!/bin/sh
IPADDR=
DOMAIN=
USERID=
PASSWD=
wget -q -O /tmp/dyndns.log \
--user-agent="e-smith-dyndns.org/0.1" \
http://"$USERID:$PASSWD"@members.dyndns.org/nic/update?\
system=dyndns\&hostname="$DOMAIN"\&myip="$IPADDR"\&wildcard=ON
