Hello,
I'm trying to create virtual wifi hotspot using the app in screenshot, although there is no errors after running it but it doesn't create a wifi connection.

The app depends on create_ap, so i tried to run it to see what happens.

Code: [Select]

MLD> create_ap wlan0 eth0 MLD-Hotspot wifi0000
WARN: Your adapter does not fully support AP virtual interface, enabling --no-virt
Config dir: /tmp/create_ap.wlan0.conf.XXfyvsjZ
PID: 6615
Sharing Internet using method: nat
iptables v1.6.0: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Doing cleanup.. done
The problem is there are no iptables modules in MLD
I looked in my Ubuntu system, those modules should be in the following path

/lib/modules/5.x.x/kernel/net/ipv4/netfilter/iptable_filter.ko
/lib/modules/5.x.x/kernel/net/ipv4/netfilter/iptable_nat.ko
/lib/modules/5.x.x/kernel/net/ipv4/netfilter/ip_tables

Is it possible to compile them myself?
Any guide please?

Here is the app link in case someone interested to try it.

Best Regards.

May be you should try the iptables package

Hi Claus,
It works great after building iptables package in docker container 
Thank you very much.
I only had to repack it coz of the following error

Code: [Select]

Unpacking iptables (1.6.0-3+5.4.20.202.42) ...
dpkg: error processing archive iptables_1.6.0-3+5.4.20.202.42_amd64.deb (--install):
 trying to overwrite '/lib/modules/5.4.20.202.42/kernel/net/llc/llc.ko', which is also in package network-wireless-drivers 0-10.6+5.4.20.202.42
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
By the way, i don't know why i see this warning message
WARN: Your adapter does not fully support AP virtual interface, enabling --no-virt
It doesn't show up on Ubuntu system.
Any idea?

[clausmuus]

I have change the testing network wireless package. Please test if the conflickt is now gone.

[gr4vity]

I have tested it, network-wireless-drivers package doesn't conflict with iptables package anymore.

By the way, i will ignore the following msg as long as wifi internet sharing connection is working fine.

Code: [Select]

WARN: Your adapter does not fully support AP virtual interface, enabling --no-virt

Hi Claus,

I repacked dnsmasq coz it conflicts with curl.

Code: [Select]

Unpacking dnsmasq (2.76-1) ...
dpkg: error processing archive /var/cache/apt/archives/dnsmasq_2.76-1_amd64.deb (--unpack):
 trying to overwrite '/usr/bin/curl', which is also in package curl 7.52.1-5+deb9u10
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
There is an option to share the internet from the same WiFi interface which works fine on Ubuntu as follows:

Code: [Select]

~/create_ap# create_ap wlp3s1 wlp3s1 MLD-Hotspot wifi0000
Config dir: /tmp/create_ap.wlp3s1.conf.KmB2KqkG
PID: 4179
Network Manager found, set ap0 as unmanaged device... DONE

Using interface ap0 with hwaddr 00:01:00:00:00:00 and ssid "MLD-Hotspot"
ap0: interface state UNINITIALIZED->ENABLED
ap0: AP-ENABLED
It means that my wifi adapter is supported however it doesn't work on MLD

Code: [Select]

MLD> create_ap wlan0 wlan0 MLD-Hotspot wifi0000
WARN: Your adapter does not fully support AP virtual interface, enabling --no-virt
ERROR: You can not share your connection from the same interface if you are using --no-virt option.

Any idea?

I also noticed the missing iptables modules i reported in post #1 are still not there

Code: [Select]

MLD> modprobe ip_tables
modprobe: module ip_tables not found in modules.dep

MLD> modprobe iptable_filter
modprobe: module iptable_filter not found in modules.dep

MLD> modprobe x_tables
modprobe: module x_tables not found in modules.dep
Is it possible to upgrade iptables package with the missing modules?

Best Regards.

That modules are buildin into the kernel.

[gr4vity]

Hello Claus,

The iptables package hasn't been updated since 2017, perhaps you could modify it in order to build the missing modules.

That modules are buildin into the kernel.

I don't understand, you mean that kernel 5.4.28 source doesn't have  ip_tables, iptable_filter, iptable_nat, x_tables?

[clausmuus]

No, the modules are includet into the kernel and so they are always loaded. There is no need (and posibility) to load them by modprobe.

[clausmuus]

Since the Modules are included in the kernel, you can't load them, and can't see them by lsmod.

Hi Claus,
I deleted unnecessary replies coz the problem wasn't related to iptables package.

Problem is now solved after running the following commands which i found in the developer repo.

Code: [Select]

iw dev wlan0 interface add ap0 type managed
ip link set down dev ap0
ip addr flush ap0
ip link set dev ap0 address 00:11:22:33:44:55
ip link set up dev ap0
ip addr add 192.168.12.1/24 broadcast 192.168.12.255 dev ap0
Here you go

Code: [Select]

MLD> create_ap wlan0 wlan0 MLD-Hotspot wifi0000
Config dir: /tmp/create_ap.wlan0.conf.XXvDLkXp
PID: 20086
wlan0 is already associated with channel 10 (2457 MHz), fallback to channel 10

This feature is really nice coz i was able to create an AP on the same WIFI adapter without any connected Ethernet cable. 

You should try it too, which WIFI adapter do you have?
