Dynamic network configuration.
 

Hi to all !

I have a notebook with Slackware 14; I work with different LAN and different IP configuration: static IP, DHCP, bugged DHCP, WiFi, etc.

I use Network Manager, but it does not fit my needs.

I would use a dynamic setup like Debian's guessnet.

Is there any software for Slackware ?

Thank you in advance.

What exactly are your needs? and what exactly doesn't work?

"Network Manager" works; but I have to set manually the network; all the times !

Also, until I don't apply the correct network configuration, automatic services (like qmail, fetchmail, ntp, etc.) do not work.

I need a software that selects "automagically" the network configuration (at boot time); it should choose the network configuration to apply, due to the:
- responses from a set of tests;
- mappings between test set and networks.

The tests should be based on formal rules predefined at system configuration level (i.e. ping o arping response, ESSID detection, etc.).

- Example (pseudo DSL) --------------------

test_1: ping 123.56.45.21
test_2: essid "FASTWEB-1-0dsadeYFzQK"
test_3: eth2 missing_cable

config_1:
iface eth2
address 192.168.1.2
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.1

config_2:
iface eth2
address 10.45.1.15
netmask 255.255.0.0
broadcast 10.45.255.255
gateway 10.45.1.1
dns-nameservers 145.125.26.23

config_3:
iface wlan0
address 192.168.1.2
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.1

map_1:
if test_1 and not test_3 then config_1

map_2:
if test_2 and test_3 then config_3

map_3:
if test_2 then config_2

map_4:
else dhcp

for m in map_[1234]: execute m

Does any of the networks provide DHCP?

Markus

Some network provides DHCP; but I need specific configuration.

For example, I need to use specific static IP and query nameserevers other than released by DHCP.

Well, when there's DHCP available, you can find out (automatically) in which network you are, so you could write a script which, depending on the dynamic configuration, creates a static one.

It would be more difficult to (automatically) find out in which network you are if there is no DHCP.

Markus

With NetworkManager you can have scripts in /etc/NetworkManager/dispatcher.d/ to handle connection customisation. I use this for handling my iptables rules. e.g. http://www.linuxquestions.org/questi...1/#post4579765
