[script] create_ap: Create a NATed or Bridged WiFi Access Point

OBLiQUE · 2014-09-23 16:37:15

'brctl setfd $BRIDGE_IFACE 0' and 'ip link set dev $WIRED_IFACE up' was missing ;p
I know that it can be a nice feature put it will complicate create_ap in many ways. But I will see, maybe I will change my mind.

Done. Please report here when you find some clue.

It looks like your wrapper script is the problem, I replied to the issue with more details.
Please check github regularly (or check your mails) because I will need more infos from you and it's better to talk only there about the issue.

TheSaint · 2014-09-24 22:08:16

Finally it's working now and without WiFi dongle. I had swapped from NM to wicd, otherwise in NM the interface will be turned off.
I didn't modified my wrapper and even started manually it's working fine.

OBLiQUE · 2014-09-25 05:32:46

The problem was the locale of the command outputs, because you have Chinese output the script couldn't parse correctly the output of NM.
This had as a result to not be able to set the device to unmanaged, so NM was interfering.
I fixed the issue by setting LC_ALL=C at the beginning of the script. It must work correctly now.

Please get the last version of the script from github to test it. AUR is usually updated every 1-2 days (I'm not the maintainer).

Yes im noob and im getting this error.

root@alarmpi ~]# ./create_ap -n wlan0 AP asperitas
-bash: ./create_ap: Permission denied
[root@alarmpi ~]# chmod 755 create_ap
[root@alarmpi ~]# ./create_ap -n wlan0 AP asperitas
./create_ap: line 5: syntax error near unexpected token `newline'
./create_ap: line 5: `<!DOCTYPE html>'

Suggestions would be appreciated

TheSaint · 2014-10-03 12:41:40

I doubt you installed from AUR. It seems that you tried to download from the web site and the response is not a bash script, but a html web page.

@ OBLiQUE
I'm grateful for your efforts, now even ubuntunian will benefit of your script (when using one only WiFi interface), but there's a small fee to pay, kill network-manager. This is also for Arch.
Can we figure out how to keep NM and use create_ap?

OBLiQUE many respects from my part as well for the script, things are much easier with it.

Now my situation. I can manage to share internet using the following command:

sudo create_ap --no-virt wifi1 net0 SSID Passphrase

and I can successfully connect to internet with my rest of devices (i.e. laptop, smartphone). However, I was trying to use the KDEconnect application in order to connect the smartphone with the desktop which works as the AP. Both desktop and smartphone recognize/find each other through the KDEconnect application but I cannot manage to pair them. Does anyone know if it able to pair them somehow.

@theodore
I think that connections via PAN and bluetooth are not covered by this script. Am I wrongly interpreting your meanings?

With NetworkManager below 0.9.10.0 there is no way to make it work because a feature is missing. I use NM in Arch and everything works perfect.. I don't know what you're talking about..

OBLiQUE · 2014-10-04 21:16:54

@QuiXXotic do the following:

wget https://raw.githubusercontent.com/oblique/create_ap/master/create_ap
chmod +x create_ap
./create_ap -n wlan0 AP asperitas

I don't think that this is related to create_ap. Maybe it's a bug in KDEconnect (unrelated to the AP) or maybe you have a firewall that is blocking KDEconnect. You can see here that KDEconnect use 1714 util 1764 TCP and UDP ports. So, you can do the following to open the ports:

#!/bin/bash
for x in $(seq 1714 1764); do
    iptables -I INPUT -p tcp -m tcp --dport $x -j ACCEPT
    iptables -I INPUT -p udp -m udp --dport $x -j ACCEPT
done

Or find which firewall you are using and do it properly.

OBLiQUE you are a trully savier
opening the ports worked like a charm
thank you again

dummyuser · 2014-10-15 13:07:12

first of all THANKS @OBLiQUE for this useful script!

Let's say I just need it up for few hours and I won't be at my computer to close it.
If I just kill (or soft kill ) the job from another console, or use 'timeout' by launching the script, it just ends, without "Doing cleanup..."
I have to manually put down br0 and wlan0....

There's any better way to "emulate" ctrl+C and close the created ap *with* proper cleanup ?

There are 2 ways:

1) You can use the systemd service. Just edit /lib/systemd/system/create_ap.service and put the parameters you want. After that you can use the start/stop of systemctl.
2) Kill the hostapd. If this is the only AP that is running, then just use: killall hostapd

BTW, if you put down manually the interfaces, hostapd doesn't exit, so create_ap doesn't exit too.

TheSaint · 2014-10-16 11:19:12

What is the default create_ap WPD ?
I'd rather like to use /tmp.

OBLiQUE · 2014-10-16 11:26:09

create_ap it doesn't change a working directory but it uses absolute paths and it writes only in /tmp.
when you run it, you will get something like:

Config dir: /tmp/create_ap.wlan0.conf.41iyR40w
...

The letters after the last dot (in my case 41iyR40w) are random. This is where create_ap write the configs and some other infos that are needed.

I was killing the create_ap script, not hostapd

cyberwoodman · 2014-10-16 12:32:24

I'm curious how can i shape increase or decrease up/down-load network traffic on my software access point? Thanks.

OBLiQUE · 2014-10-16 12:52:55

You can use tc. Check this: https://wiki.archlinux.org/index.php/Ad … ic_control

I use this script on my raspberry connected to the router.
It work fine but I can't get how to assign the same subnet of my router to wifi device.
My router assign ip like this: 192.168.0.XXX and create_ap assign 192.168.12.XXX
I tried the bridge option and with that i can obtain the same ip of my router, but with that i can't no longer access to my raspberry (ssh, samba, etc)
Some suggestion?

OBLiQUE · 2014-10-25 11:32:54

Lets say you connect your raspberry pi with eth0 and you get the ip 192.168.0.13, then you run the following:

create_ap -m bridge wlan0 eth0 MyAccessPoint MyPassPhrase

Then connect to the access point that you created, after that try to ping raspberry (192.168.0.13 in my example). If ping works but you still cannot connect to raspberry's services then the problem is something else (probably the firewall). If you can not even ping the raspberry pi then let me know.

PS: make sure that you have the latest version of create_ap, you can get it from github repository (I have it on the first post)

Thanks for the answer. I try like you told me (which is the same way I had tried it) and now is working. Go figure.

Can you tell me how to remove the WiFi Access Point that was created in this way

OBLiQUE · 2014-11-07 11:52:20

what do you mean by "remove"?
