I will improve it in the near future after I have it restructured. It's then also easier to implement little changes
Automatic backup of config using a "pull method"
- Ersteller frater
- Erstellt am
I have restructured the script and tested it against the cluster of modems I am supervising.
It relies on 'httping' to be installed
The script can take command line parameters now...
- -c use current directory instead of default
- -d <folder> use <folder> instead of default
- comma delimited parameters for 1 modem (same syntax as the list)
If no parameters for a modem are given, it will search for a list containing modem parameters in the designated folder and parse that list and fetch both the Freetz config and the AVM-config.
The parameters for 1 modem can be as basic as its external address. It will then use the default values for the rest....
The AVM-config is password-protected with the external password.
The files will be placed in a folder and get a little check. If the config is (about) the same as the last one fetched, it will get discarded.
This way you can just create a symlink to the script in /etc/cron.daily and you will always have a folder with different configs.
You can easily see when a config has been changed.
I'm placing those files in a password protected website where I can immediately download one of the configs I need....
Maybe it will save my ass one day...
It can now also get the AVM-config if there's no freetz on it.
If it doesn't detect the Freetz interface it will do an AVM only.
If you don't want to even try the Freetz-port you can define it as port 0
The script could do with some better logging and maybe there are some bugs there.
If you use the script I would appreciate some feedback.
I also would like to know if I should bother posting updates here.
Thanks Daniel and MaxMuster for the URL's I needed to get..
Update May 18 17:30
Added better handling for "#"
You can put comments at the end of the modemline and of course in the beginning
Everything behind the # will be ignored...
Also added some code to prevent duplicate AVM-configs (in case Freetz is not used)
Update May 18 00:00
Not only remove the path, but also the extension from the name of the script to use as the name for modemlist
Update May 19 12:00
I should spend my holidays better, really...
Another improvement to make the detection for changes a bit better and more sensible.
If only an AVM-config is made, the script kept the config too often. I now check for big differences by ignoring the binary data in the config.
If, however, the latest config is older than 30 days the script does an exact comparison.....
Update May 20 13:15
The script still made some unnecessary backups, so I investigated it and improved the comparison. Added some extra logging...
If used as a cronjob, it will only output data if a changes is found....

Great work! I'll try the new version in the next days.
I would like to see your updates here
BTW:
I would like to see a commandline for the list of modems since i'm using .sh on my shellscripts at the end and so my list would be named freetz_getconfigs.sh.list

@vice_pres...
I did some modifications over the weekend and I'm considering the script stable and full featured now.
I also added some code to get rid of the suffix (in your case .sh), but I just re-read your post and you wanted it in there...
A bit strange as it was using a "freetz_getconfigs.sh.list" in the old version of the script if the name of the script was "freetz_getconfigs.sh"
I now especially added code to get rid of the suffix if one exists and am going to leave it that way as it's much neater...
I tested the script to get the AVM-config from LAN-side. It works!
It needs to use http instead of https and it does this by looking at the port. If it starts with an "8" it will use http instead of https.
I enhanced the method to better determine a changed config. Dynamic data like phonebooks are deliberately being ignored.
I would get too many configs if I didn't (backups should be done automatically).
I'm keeping the oldest config, because you will then also have the info when that config has been changed.
The downside of this approach is that you may not have the latest phonebook data in your config.....
Maybe I will modify the script (by request) if someone would prefer to keep the newest config (and kill the older similar one)

Just a quick note - after upgrading my Ubuntu to 14.04 the script doesn't work because curl changed it behaviour. I had to add --cipher RC4-SHA to every curl call to get the script working again.
Thanks vice_pres for this feedback!
I have modified the code based on your findings.
I do make a difference between https / http connections (in case the program is run from the inside of the Fritzbox).
No idea what curl does when I supply these options on a plain http, but it is always better to keep code clean and supply parameters as they are expected... (garbage in => garbage out).
Can you confirm this code is working at your end?

Hi,
Code is working, I'm using a version I modified a bit (for example storing hostnames in the filename instead of ip because they are dynamic) etc - but tried your code in a new file and it's working
Edit:
I changed something to the sed when comparing the configs since the passwords seem to be rehashed everytime something is changed via webinterface - so there would always be a diff...
sed '/ BINFILE:/,/ END OF FILE /d;/ [0-2][0-9]:[0-5][0-9]:[0-9][0-9]/d;/END OF EXPORT/d;/\$\$\$\$/d'

I will look into that sed later. I did notice some configs get an update when in fact nothing really changed.
I don't understand your remark about the dynamic host.
My script fully supports dynamic hosts. Just leave out the IP.

Yeah, but the script stores the files with the ip-adress - and I find it more usefull if the script stores the hostname instead.
Because you set DEST_BASE="${DEST_FOLDER}/${IP}.${DATESTAMP}" and I modified it to be DEST_BASE="${DEST_FOLDER}/${HOST}.${DATESTAMP}"
Code:
test.dyndns.org
Saving "/new/test.dyndns.org/83.20.222.212.2014-04-27.16-06.export" because no previous AVM-config has been foundBecause you set DEST_BASE="${DEST_FOLDER}/${IP}.${DATESTAMP}" and I modified it to be DEST_BASE="${DEST_FOLDER}/${HOST}.${DATESTAMP}"
Hi,
Since 06.30 the '--cipher RC4-SHA' option is not needed anymore - in fact it stops the backup from working.
Since 06.30 the '--cipher RC4-SHA' option is not needed anymore - in fact it stops the backup from working.
I will check my script and publish the new one...
I will also check why I have a "new config" each day. Something must have been added that changes every day.
I need to add something more to the ignore part..
Will post something soon

I modified the Script to have the HTTPS_Option as an extra option in the config file - since I have some Boxes that don't get 06.30 anymore (7270 for example) and need the cipher. But since I started on an older version of your script a diff is rather long - plus the modifications I wanted (storing in folder named as the hostname etc...). This version works fine for all boxes I'm backing up - the 06.30 Boxes get backed up almost daily (but not daily - some days there are no diffs. I assume it's the call log that changed and triggers an backup)

Anyone has a quick fix?
Somehow the challenge fails....
EDIT...
The root cause must lie somewhere else.
The script works fine on another 7490 with 6.83 (a higher version, but I will test some more)
EDIT
I found the root cause
It's that two factor challenge method that's spoiling it (where one needs to press a button).
I just tried a manual backup and that failed for these same reasons.
# Edit ar7.cfg and change two_factor_auth_enabled
nvi /var/flash/ar7.cfg
two_factor_auth_enabled = no;
# Stop ctlmgr
ctlmgr -s
# Start ctlmgr
