I have a DGND3700 which has a dynamic update option for dyndns but I would like to add an opendns updater and was wondering if this was possible, I dont want to use the live parental controls that come with this router as they do not work properly.

I can access the router via telnet and get the below but I am very new to linux:

BusyBox v1.00 (2011.09.17-03:36+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.

~ # ls
bin      dev      lib      mnt      proc     sys      usr      www
data     etc      linuxrc  opt      sbin     tmp      var

Would it be possible to add a script that can run on router start up that will update opendns, I found some sites below with info but have no idea how to implement on this router, they mention curl? which I am not sure is an option:

http://bassmadrigal.com/blog/2008/08/op … ough-linux

Please help.

Would some how getting the router to run this work:

"It's possible to update the IP using an HTTP request. I use the following command in a cron job:

wget -O - -q --http-user=USERNAME --http-passwd=PASSWD https://updates.opendns.com/nic/update"

telnet in again and run that command in the shell. see how it goes (and if wget is available).

Thank you, it does indeed have wget but I get an error

wget: unrecognized option `--http-user=USERNAME

tried with just --user but the same, is this to do with the versionn of wget?

Most likely, yes. It might be a stripped down version, either manually or the busybox version. try wget --help to see what it supports and which version it is.

~ # wget --help
BusyBox v1.00 (2011.09.17-03:36+0000) multi-call binary

Usage: wget [-c|--continue] [-q|--quiet] [-O|--output-document file]
                [--header 'header: value'] [-Y|--proxy on/off] [-P DIR] url

wget retrieves files via HTTP or FTP

Options:
        -c      continue retrieval of aborted transfers
        -q      quiet mode - do not print
        -P      Set directory prefix to DIR
        -O      save to filename ('-' for stdout)
        -Y      use proxy ('on' or 'off')

~ #

I tried this "wget -O - https://bilbonvia:123456@updates.opendns.com/nic/upda
e?hostname=home"

but doesn't support https either. Tried to compile a new wget using instructiuons on internet but got:

/tmp/wget-1.5.3 # ./configure
loading cache ./config.cache
configuring for GNU Wget 1.5.3
checking host system type... mips-pc-linux-gnuoldld

configure: error: no acceptable cc found in $PATH
/tmp/wget-1.5.3 #

If I knew whetre the dyndns config was or how to browse maybe I could modify that?

I have downloaded the dgnd3700 sdk, looks like you can compile it failry easily.

Would it be possible to modify one of the source files with a opendns updater, how would I do it? Then compile?

maybe this might be something you want: http://bddc.klienux.org/

If you want a "full" version of busybox there are precompiled static binaries available.
http://busybox.net/downloads/binaries/
Select mips or mipsel depending on which your router has. The DGND3300 and WNDR3700 are both mipsel so I'd think the DGND3700 would be as well. Upload the file to a USB stick then copy it to /tmp
chmod +755
then you can run from /tmp as below
./busybox-mipsel wget blabla-bla.com/files/to/get
Or just run it with no options to see what is available.
You can put it in places other than /tmp or even leave it on the USB drive if the DGND3700 allows you to mount ext2,3,4 filesystems.

On the router I changed to /tmp and did a wget http://busybox.net/downloads/binaries/l … box-mipsel

chmod 755

but when I try to run it I get:

/tmp # ./busybox-mipsel wget
./busybox-mipsel: 1: Syntax error: "(" unexpected

edit, the mips version works but unfortunately the wget version in the latest busybox is not supporting https.

Any luck compiling your own wget?

no not been able to get it figured out. No massive issue , I'll have to settle for the software client updater for now.

You need busybox-mips and not busybox-mipsel.

I've made a script which enable telnet, connect to the router and launch a script placed on the usb key.

Set oSh=CreateObject("WScript.Shell")
WScript.Sleep 500: oSh.Run "telnetenable 192.168.1.1 204D7B0B892F Gearguy Geardog"
WScript.Sleep 500: oSh.Run "telnet 192.168.1.1"
WScript.Sleep 500: oSh.SendKeys "/tmp/shares/USB_Storage/test.sh"
WScript.Sleep 500: oSh.SendKeys "{ENTER}"
WScript.Sleep 500: oSh.SendKeys "exit~"

It's just a bad senkey, but it works.

ps: telnetenable must be in the same directory...
