network managet and 10.42.0.1/24

[Bhasker C V]

Hi all,

 I am at a loss to find out how to change 10.42.0.1/24 and 10.42.0.x/24 as ip and dhcp range which is used by network manager when configuring a wireless card as an AP. I dont see the setting anywhere and cant find a valid doc in the internet too

Is this value had-coded in the source-code of NetworkManager ?

Has anyone got an experience of making Network manager work aas a DHCP server with custom DHCP range ? please if you can share your experiences

thanks

The Debian Administrator's Handbook has the information for setting up a DHCP server in it.  Check out the following link:

https://debian-handbook.info/browse/stable/sect.dhcp.html

That ought to get you started, at least.

thanks

Thanks. I can understand that the doc is about setting up a separate DHCP server. However, I want to use network manager's functionality to create a hotspot and also be able to control the dhcp range of this hotspot.

This is where I got stuck with the 10.42.0.1

Sorry, then, I can't help there. I've never used NetworkManager in that way. Maybe someone else here will know more.

I had (and still partly have) the same questions. I know where to find the answers, but didn't dare to use them.

--First "nmcli -p connection show --active" will show all your connections. Or me the access point has name (not id) "Hotspot" (I don't know if the name depends on the device and driver).

--Then "nmcli -p connection show --active Hotspot" gives all the details, including 802-11-wireless.ssid (the hostname), 802-11-wireless.mode ap (access-point I guess),IP4.ADRESSE[1] (ip = 10.42.0.1/24, gw = 0.0.0.0), IP6.ADRESSE[1] (ip = fe80::7e5c:f8ff:fe8e:9473/64, gw = ::) and many other infos.

--What I didn't dare to do was to try "nmcli connection edit (or modify) Hotspot".

--What I did was to modify my DNS setup. In my master zone I added 10.42.0.1 as ip-address for my server (which now has 3 addresses, one for the outside, from my ISP, one not routable for my local network 192.168.xxx.1, and 10.42.0.1, not routable also). In the zone file I added also fixed addresses 10.42.0.xxx for some devices (e.g. a printer which has two addresses 192.168.10.6 and 10.42.0.6; this allows wifi clients to use this printer. I also added a reverse zone 10.42.0.zone.

I can't remember how I managed to exclude the fixed addresses from dhcpd range to avoid conflicts but it works. Hope this will help.

Sorry for my English.

Managed to change the IP to any IP you want to setup and use.
