DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hi Fordem,

The SNMP Agent of choice in the Linux world is Net-SNMP:  http://www.net-snmp.org/

However, for such a device like the DNS-323, you would need a tailored MIB / Agent that would reflect the status information you can obtain via the Web Console.
Could be cool to program, actually

Cheers,
Loïc.

better it seems to me to have ie. telnet running through funplug, than running some scripts for
1. uptime
2. fanspeed
3. temperature
4. hdd space

Better, perhaps not. But easier to implement!

Due to a nice feature of the DNS, you capture any info you want off the box by going to the different info pages in the /proc directory via the built in web server.

Ie
http://dns323/proc/version
http://dns323/proc/cpuinfo
http://dns323/proc/net/arp
   etc...

CD to /proc and do an ls -l to figure out all the stuff you can read via simple http requests.

My 323 arrived yesterday and whilst I'm waiting for it to finish backing up my system I wrote a Vista Gadget thing to monitor it. So far I can of course display all the stuff I can get from the web server pages, and I've got a "shut down" and "restart" button - you know the sort of  thing. I'm too lazy to log into the thing to check how it is and muck about with it.

It's hardly SNMP and I have to poll, but at last I know what's up with the thing.

Those /proc references are precisely what I need to add a few more features. However as I can't actually telnet to the thing, I can't actually get a list of all the things I could get there... would someone care to post a full list? I'll publish the gadget once it's done, if anyone can't think of a better way to do this.

Thanks for the list - I'll have a poke about with that the next time it rains, if no one else suggests an easier way to do this.

I just put the gadget here:
  http://www.wigglesworld.klebos.com/stuf … efault.asp

The version there (0.3) is slightly brain-damaged as the "shut down" and "restart" functions aren't enabled - I'm in the middle of a big multi-day backup to this box so I can't test shut down/ restart, although those should be trivial to implement.

All polite feedback/ suggestions welcome, although I don't guarantee to take notice of it. As I've only the one system here to test on, there may be some crass defect which prevents it working for others for all I know.


This is basically doing the same POST thing you mention; you could run it on a web server except for a few "gadget" specific surrounding things which I only just learned about.

Yeah, I noticed that. I even managed to kill the www server on it without being logged in... definitely you don't want to expose that server to the wild internet! Fortunately killing the www didn't kill the box, as my day-and-a-half backup is still running and I don't want to check if it fails sensibly on that! Whilst it's a bit careless, it's a domestic machine as you say.

I like the idea of red/green/amber - I'll put it on the list.

To get the shutdown to work I had to uncomment the line

makeServerRequest( "/goform/sysShutDown",  "GET", null, null ); //Get tools page.

Note that I also had to change the POST to a GET.  I haven't spared any thought yet as to why I needed to do this given your code.

A few other suggestions:

password field should show asterisks when typing (change type="text" to type="password" on the relevant line in settings.html)
pressing your reload button displays plain text password - not sure how to change this other than not to display it on refresh/reload (i.e. remove the code which fetched the pwd)
change function of 'refresh stats' to 'restart dns' - as you mention on your webpage the 'reload gadget' serves the same function (which I see is already on your todo list)
allow tickboxes in the options page to allow user selection of individual items - i.e. some people may not need dns/gw/mac address etc displayed and may prefer something else instead.
colour buttons :-)

I mentioned previously that logging in was not required to shutdown the unit or for some other purposes.  Various complaints have been made about the security on the dns323, and in the future, who knows, dlink may actually do something about this - which would break you gadget if you do modify it.  But in any case the dns323 admin web interface (that you are using to populate the gadget) is irrelevant and unnecessary to access files in /proc and /etc

As to signing the gadget look here: it seems pretty simple.  Also see http://msdn.microsoft.com/en-us/library/bb498012.aspx

Ok I finished that as far as I'm going with it for now - the version at the link above has pretty restart/ shutdown buttons and multiple pages of data from the NAS.

Pages:
  network : Not much use as they don't change.
  status: usage and temperature graphs, configurable temperature colouring
  os: garbage from *nix plus the uptime as hh:mm:ss
  clients: client IP address lists

Buttons:
refresh (there's also a configurable background refresh timer)
restart
shut down

Settings for all the stuff I think needs to be a setting.
That's version 0.7.

------
limitations: only implemented for a single disk NAS, no RAID.

-------
Other stuff:
I went through the other god-awful /proc commands, some of which crashed the www server on the NAS. I did think of implementing a "crash www server" button, but on balance I decided to ignore all those I could see no use for.

It's table-driven so it's pretty easy to add other commands - you just need to know the url and the format of the output. Then add an entry into the state-table for the command, with a reference to the formatter to parse the output from it.

I will try  XP WIndows Then i will tell you...
