It seems active now. Only [1370]: bad address at /etc/hosts line 3 messagge is red.
And also message: group 'dnsmasq' does not exist.

Authentification still doesn't work.

I think we should add the group dnsmasq.

groupadd dnsmasq

Should I ???

hondagx35

No risk, no reward!

But it has nothing to do with authentification.

P.S.
I made a new and fresh image, updated to latest nightly build and followed my own HowTo.
All works like it should.

The problem was here:

Feb 22 15:40:19 runeaudio dnsmasq[366]: reading /etc/resolv.conf
Feb 22 15:40:19 runeaudio dnsmasq[366]: using nameserver 192.168.1.1#53

I tried to modify resolv.conf to set nameserver 192.168.2.1, but reading from wikiarch, it seems that dhcpcd tends to overwrite /etc/resolv.conf by default, so I have to protect /etc/resolv.conf. To do this, append nohook resolv.conf to the dhcpcd config file. Otherwise It is also possible to write protect your resolv.conf:

chattr +i /etc/resolv.conf

The last one solve my problems. Now I can connect to RuneAudioAP, even if the message status is not completly clear:

Hi mrcrowley,

I tried to modify resolv.conf to set nameserver 192.168.2.1, but reading from wikiarch, it seems that dhcpcd tends to overwrite /etc/resolv.conf by default, so I have to protect /etc/resolv.conf. To do this, append nohook resolv.conf to the dhcpcd config file. Otherwise It is also possible to write protect your resolv.conf:

This is nonsense, please do not follow this approach!

OK I did some work for you:
Your redis entries are

mrcrowley wrote

[root@runeaudio ~]# redis-cli hgetall AccessPoint
 1) "enabled"
 2) "1"
 3) "enable-NAT"

Let us use 192.168.2.xxx (it only has to be different from your local network).
Your redis entries have to look like this.

 1) "enabled"
 2) "1"
 3) "ip-address"

Fix your redis database entries and it will work as expected.

I have already done. Should I give

chattr -i /etc/resolv.conf

to get back permission right ???

And how modify redis ??

mrcrowley

redis-cli hset AccessPoint dhcp-option-dns "option:dns-server,192.168.2.1"

redis-cli hset AccessPoint dhcp-option-router "option:dns-server,192.168.2.1"

???Confirm ??

hondagx35

Hi,

???Confirm ??

Wait.

it seems that dhcpcd tends to overwrite /etc/resolv.conf by default

"dhcpcd" shouldn't run at all on your system.

What is the output from:

systemctl status dhcpcd

If it says "running" you should stop and disable it.

systemctl stop dhcpcd
systemctl disable dhcpcd

Also check the file /var/www/command/rune_SY_wrk.
The lines belonging to "dhcpcd" should be commented out.

mrcrowley wroteI have already done. Should I give

...

Yes.

How can I delete 15) and 16) ???

hondagx35

Hi,

you can delete entries with "hdel":

redis-cli hdel AccessPoint dhcp-option

Frank

mrcrowley

I delete it, but after reboot it comes again with ip 192.168.1.1
I don't know how, but anyway it works.
With this value

[root@runeaudio ~]# redis-cli hgetall AccessPoint
 1) "enabled"
 2) "1"
 3) "enable-NAT"
 4) "1"
 5) "ip-address"
 6) "192.168.2.1"
 7) "broadcast"
 8) "192.168.2.255"
 9) "ssid"
10) "RuneAudioAP"
11) "passphrase"
12) "zakkwylde2012"
13) "dhcp-range"
14) "192.168.2.2,192.168.2.254,24h"
15) "dhcp-option-dns"
16) "option:dns-server,192.168.2.1"
17) "dhcp-option-router"
18) "option:dns-server,192.168.2.1"
19) "dhcp-option"
20) "option:dns-server,192.168.1.1"

I can connect to RuneAudioAP.

And dnsmasq status is:

Sorry to bored you again Frank but, what do you think of what I got now ???

I try RuneAudioAP for a while, and I notice that sometimes the tablet lost connection and soon get it back.
I don't know exactly, if it happens when tablet go to sleep mode or what. I will do further investigation.
