Fritz Fun
|
|
=========
|
|
|
|
If you want to receive facsimilies (fax) via your Fritz!Box, you can do that via the internal fax receiver.
|
|
If you want to **send** faxes from Ubuntu, you can install the [ffgtk](http://wiki.ubuntuusers.de/ffgtk)-package.
|
|
The original homepage of the project is [tabos.org](http://www.tabos.org/ffgtk/). With it installed, you will get
|
|
a new "Fax" printer to send faxes and it can also receive faxes directly to your PC.
|
|

VPN
|
|
===
|
|
|
|
You can set up your FB to accept VPN connections. As a client, you can use the free [Shrew Soft VPN Client](http://www.shrew.net/).
|
|
How to set up the client is explained in the [AVM VPN portal](http://www.avm.de/de/Service/Service-Portale/Service-Portal/index.php?portal=VPN) (see bottom right box).
|
|
|
|
|
|
Static DHCP
|
|
===========
|
|
|
|
The FB only supports "static DHCP" in the way that you can mark devices so that they keep their currently
|
|
(via DHCP) assigned IP address. You can not manually set the IP address you want.
|
|
|
|
So you could now go the easy way and enable *Telnet access* to the device and change the DHCP table directly.
|
|
But this way you won't get any support from AVM and also you will get a nasty warning message in the web interface.
|
|
|
|
Another way is to export the configuration and change the entries there. If you know how to update the checksum,
|
|
you can use any text editor program. But if you just want to make a few changes without learning how to calculate
|
|
the checksum, there's a Java program called [FBEditor](http://www.ip-phone-forum.de/showthread.php?t=79513).
|
|
|
|
Just download it, enter the IP and password of your FB and there you go. Any changes you make inside the program
|
|
will automatically update the checksum so that the FB will accept your changes.
|
|
|
|
So now it's easy to change the `dhcpserver` ⇒ `statics` section or the `landevices` ⇒ `landevices`.
|
|
|
|
<p><div class="noteimportant" markdown="1">
|
|
If you make any changes to the *Network* settings in the web interface, the changes you made by editing the file
|
|
will probably be deleted. At least if the third byte of an IP address doesn't match the FB's one. (e.g. if you have a class B network)
|
|
</div></p>
|
|
|
|
|
|
Generate static DHCP configuration from a file
|
|
----------------------------------------------
|
|
|
|
If you have several devices in your home network and the FB keeps deleting them from their settings, you can create
|
|
a file with all your devices and generate the appropiate FB settings from it.
|
|
|
|
So first, create a file `static.list` which looks like this (fill in the data of your own hosts):
|
|
|
|
~~~
|
|
00:21:85:C0:FF:EE mypc 172.16.1.1
|
|
00:16:D4:C0:FF:EE wife-pc 172.16.1.2
|
|
00:18:39:C0:FF:EE slug 172.16.254.253
|
|
00:25:00:C0:FF:EE iphone 172.16.1.10
|
|
00:1E:A9:C0:FF:EE wii 172.16.1.11
|
|
00:22:69:C0:FF:EE netbook 172.16.1.3
|
|
00:C0:EB:C0:FF:EE printsvr 172.16.254.252
|
|
~~~
|
|
|
|
Then you only need this little Python script (and *[Python](http://www.python.org/)*, of course):
|
|
|
|
{% highlight python %}
|
|
#!/usr/bin/env python3
|
|
# -*- coding: utf-8 -*-
|
|
|
|
__author__ = "mbirth"
|
|
__date__ = "$2009-12-19 17:37:38$"
|
|
|
|
f = open( "static.list", "rt" )
|
|
entries = []
|
|
for line in f:
|
|
line = line.strip(" \n")
|
|
( mac, sep, post ) = line.partition(' ')
|
|
post = post.strip()
|
|
( host, sep, ip ) = post.partition(' ')
|
|
ip = ip.strip()
|
|
entries.append( ( mac, host, ip ) )
|
|
|
|
print( "%i hosts found." % len( entries ) )
|
|
|
|
statics = " statics"
|
|
for entry in entries:
|
|
statics += " {\n"
|
|
statics += " macaddr = " + entry[0] + ";\n"
|
|
statics += " ipaddr = " + entry[2] + ";\n"
|
|
statics += " }"
|
|
|
|
print( "#### dhcpserver > statics" )
|
|
print( statics )
|
|
|
|
|
|
landevs = " landevices"
|
|
for entry in entries:
|
|
landevs += " {\n"
|
|
landevs += " ip = " + entry[2] + ";\n"
|
|
landevs += " name = \"" + entry[1] + "\";\n"
|
|
landevs += " mac = " + entry[0] + ";\n"
|
|
landevs += " medium = medium_ethernet;\n"
|
|
landevs += " }"
|
|
|
|
print( "#### landevices > landevices" )
|
|
print( landevs )
|
|
{% endhighlight %}
|
|
|
|
Custom DNS
|
|
==========
|
|
|
|
To use custom DNS entries instead of those given by your ISP, use the
|
|
[FBEditor](http://www.ip-phone-forum.de/showthread.php?t=79513) and find the entries
|
|
|
|
overwrite_dns1 = 0.0.0.0;
|
|
overwrite_dns2 = 0.0.0.0;
|
|
|
|
Now just insert your desired DNS servers, upload the changed config and you should be set.
