Hi,

I came across some script that uses upnp to read out some information of the FritzBox!.
I have this script in my /domoticz/scripts folder and in my crontab:

Code: Select all

#!/bin/sh

#FritzBox settings
FRITZUSER=root
FRITZPASS=<passwd>
FRITZIP=<ip>
FRITZPORT=49443

#domoticz settings
dom_host=<ip>
dom_port=<port>
dom_url="json.htm"
dom_status_idx=<idx_dummyswitch>

cd ~/domoticz/scripts
wget --quiet --user=$FRITZUSER --password=$FRITZPASS --post-file=linkstatusrequest.xml \
--header="Content-Type: text/xml" \
--header="SOAPAction: \"urn:dslforum-org:service:WANCommonInterfaceConfig:1#GetCommonLinkProperties\"" --no-check-certificate \
https://$FRITZIP:$FRITZPORT/upnp/control/wancommonifconfig1 -O linkstatusanswer.xml
Internet=`cat linkstatusanswer.xml | grep PhysicalLinkStatus | cut -d '>' -f 2 | cut -d '<' -f 1`
DOMO_STATUS=`curl -s "http://$dom_host:$dom_port/$dom_url?type=devices&rid=$dom_status_idx" | grep Status | grep -v Name | cut -d '"' -f 4`
case $Internet in
        Up)
                if [ $DOMO_STATUS != "On" ]
                then
                        URL_DOMO=`curl -s "http://$dom_host:$dom_port/$dom_url?type=command&param=switchlight&idx=$dom_status_idx&switchcmd=On"`
                fi
                ;;
        *)
                if [ $DOMO_STATUS != "Off" ]
                then
                        URL_DOMO=`curl -s "http://$dom_host:$dom_port/$dom_url?type=command&param=switchlight&idx=$dom_status_idx&switchcmd=Off"`
                fi
                ;;
esac

It updates a dummy switch if the status of the reply fro Fritzbox changed.
For the upnp-request is uses a linkstatusrequest.xml file that should be in the same folder:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope
   xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"
   s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
   <s:Body>
      <u:GetCommonLinkProperties xmlns:u="urn:dslforum-org:service:WANCommonInterfaceConfig:1">
      </u:GetCommonLinkProperties>
   </s:Body>
</s:Envelope>

I use this setup for a lua-script that checks this dummy switch. If Internet is down for more then 20 minutes, i turn off the power to the modem, and a few minutes later turn it back on.
Just made the last bit today, so needs some testing, but looks ok for now.

Hope some other Fritzbox user can use this

Good morning,
thank you for this script - very interesting.
Would you mind to share where you found the script ? It would be usefull to try to get some other information out of the Fritzbox and use it in domoticz.

Thanks a lot !

Cheers
Josh

What's the benefit of this? The modem will try to reconnect by itself i guess?
By powercycling the modem, the 'line training' (Dutch: 'intrainen op lijnsnelheid') (determining fastest speed achievable) will start over again i guess?

I do the same, but that is with internet over coax, where there is no line traning: http://thinkpad.tweakblogs.net/blog/120 ... tproblemen
And with the Ziggo modem it sometimes requires a reboot after they have done maintenance works.

Reason i say this: i once read somewhere there was someone that wanted to turn off his ADSL / VDSL modem at night with a timer clock, to reduce energy consumption. But someone responded that it was not advisable because of the line training process.

The script upnp/xml bit comes from http://idefix.net/~koos/newsitem.cgi/1417032285
There is some a tiny bit more info in the output-xml, but i don't use that. I tried to get more info with other input .xml's but i did't get that working.

Sometimes it happens, after some maintenance i guess, that the modem doesn't recover the DSL-status. A powercycle will fix it then.
The 'line training' is only with a new modem, or when disconnect for a longer amount of time, i think.
Before i had some issues with wifi and a reset of the modem fixed that too, but didn't effect my DSl-speed (which occur at a reset of the line-training).

I don't expect it to happen on a daily/weekly/monthly base, but thought it would be nice to have.

hi .. maybe anyone can use this attachement to implement a full FritzBox support. it's perl...

would be nice to check wifi and some other settings... note: telnet is required and have to be activatetd on fritzbox via telephone^^

To reboot it, it doesn't even seems necessary to interrupt the power. See this page for a script that tells the Fritz!box to reboot.

Code (in case the page isn't working anymore):

Code: Select all

#!/bin/bash
_BOXURL="http://fritz.box"
_USERNAME=""
_PASSWORD="GEHEIM"
_CHALLENGE=$(curl -s ${_BOXURL}/login.lua | grep "^g_challenge" | awk -F '"' '{ print $2 }')
_MD5=$(echo -n ${_CHALLENGE}"-"${_PASSWORD} | iconv -f ISO8859-1 -t UTF-16LE | md5sum -b | awk '{print substr($0,1,32)}')
_RESPONSE="${_CHALLENGE}-${_MD5}"
_SID=$(curl -i -s -k -d 'response='${_RESPONSE} -d 'page=' -d "username=${_USERNAME}" "${_BOXURL}/login.lua" | grep "Location:" | awk -F'=' '{print $NF}' | grep -Po '[a-f\d]+')

# Box rebooten
echo 'Reboot in progress ... please allow up to 2 minutes for the box to come up!'
curl -s "${_BOXURL}/reboot.lua?sid=${_SID}&extern_reboot=1&ajax=1" >/dev/null

The author also made some scripts to extract information from the webinterface: http://www.administrator.de/contentid/214598

Oh, that looks interesting

My German is not that great, hehe. And it seems it needs telnet-support, altho i don't see that in the script itself. (or does it mean you don't need the telnet ?

)
Allowing telnet on the Fritzbox makes it display "Unsupported changes made", or something. I had it on old modem, and don't want to do it again, to be honest.

I'll look into the script tho, thanks for pointing them out, i had searched for scripts like these, but didn't find this.

It doesn't need Telnet. It logs in via curl and scrapes the values.

Hello,
Is there any progress made on getting information from the fritzbox?
I am very interested.

Regards, Hans

Hey,

I didn't put any effort in it for the last .. well, year it seems

But last week I had some time on my hands and tried to expand the information i extract from the FritxBox!.
With a new script and some extra .xml-information I had the Upstream and Downstream bytes put into a counterfield.
It was showing some good numbers, but sometimes bad numbers also. Not sure if that is because i used a counter-device or something.

When i wanted to fix it last weekend, my SD-card in the Pi got corrupted, twice ...
(Yes, now there is a new shiny SD-card in it, with a backup SD-card with a backup-image of the first right besides it)

And you'll see, the folder i had these scripts in, wasn't in the backup-job

I'll try to recreate them from memory, but not sure when.

But don't expect to much/complicated things (from me anyway)
