[Solved]Connection of my Arch PC via Ethernet stop all other connect

sweetthdevil · 2014-03-04 18:41:14

Hi all,

This is weird! I updated my arch pc today, and I realised that all other connection to the router (a UK skybox) stop.

Per example, if my Android phone is connected before the PC starts - the connection to the router remain live, but while trying to access a web page I have a you are offline page. If the phone isn't connected before the pc is started then the phone simply refuse to connect to the router!

Looking at the logs from the skybox no update was done recently - and booting the PC onto windows and it all work normally.

I am connected via ethernet with a local static IP.

I have no idea where to look, any suggestion would be greatly appreciated.

Thanks,

Right,

tried to downgrade network-manager has it was updated the day the issue start - but no luck...

Any other idea?

Is your ethernet a r8169? It has been known to do this.

sweetthdevil · 2014-03-06 15:01:04

First of all, thank you for your time and interest.

My card isn't the one you mentioned see below:

lspci | grep Ethernet
02:00.0 Ethernet controller: Qualcomm Atheros AR8121/AR8113/AR8114 Gigabit or Fast Ethernet (rev b0)

I have been searching the web and my log to try figuring it out but I am puzzled has to why!?

nomorewindows · 2014-03-06 15:53:42

Might search the AUR for atheros, package dkms-alx is a atheros alx linux ethernet driver.

sweetthdevil · 2014-03-06 16:00:38

Thanks again for your time and interest.

But my pc is running arch since at least five years - and I haven't changed the motherboard since. Driver is not the issue.

If I stop my netctl profile (which is a static ip) the wifi connection returned whilst the PC is running. It must be an issue from there - but what I do not know...

nomorewindows · 2014-03-06 16:27:35

Can you get into the router? Maybe it can tell you something.

sweetthdevil · 2014-03-06 16:45:42

Right,

First of all, I resolved the issue. Just for the information I had set up my pc on a static IP address both with netctl and within the router. All my appliance were also set up within the router to have a static IP. For some reason the Skybox was not connecting to the address given and were connecting with the same IP as the pc....

The set up has been done since months - so why now? but anyway not it's back to normal

nomorewindows · 2014-03-06 16:52:24

If you're using static addresses on the PCs they don't need to be configured in the router, just avoid any possible DHCP assignment pools or using other static IPs.

sweetthdevil · 2014-03-06 18:08:22

Right,

This issue is still not solved, I rebooted the pc and the issue has restarted...

There is no more conflict of similar IP address, I removed all but one static IP from the rooter.

No hardware change, so the issue must be coming from arch, it is behind me that the wired connection will stop all wireless connection!

Any suggestions will be welcome,

ewaller · 2014-03-06 19:09:27

I note you are using using a static address.
I suspect either a DNS or a default route problem.

Can you ping 66.211.214.131 ? That is an Arch Linux server. If you can, you have a DNS problem.
If you cannot, what is the output of ip route ?

sweetthdevil · 2014-03-06 19:20:12

Hello,

and thank you for your time and interest.

Since you say it stops all wireless connection, how about trying to connect your Arch via your wifi and unplug the ethernet?

sweetthdevil · 2014-03-06 20:00:23

Well it is a desktop. BBB o wireless board.

And that is beside the point. A problem was created and I want to resolve it.

Thanks

nomorewindows · 2014-03-06 20:06:28

Never mind I thought it had a wireless card.
Can you ping archlinux.org instead of IP?

ewaller · 2014-03-06 22:02:16

Sorry, I had stepped away for a couple hours.
Take a look at your /etc/resolv.conf

Mine looks like

ewaller$@$odin ~ 1001 %cat /etc/resolv.conf 
# Generated by resolvconf
nameserver 192.168.1.1
ewaller$@$odin ~ 1002 %

You should have a nameserver line that points to your your router, if you use your router as a dns name server.
You can also point it to 8.8.8.8, a public name server that is run by Goggle.

Have you, in the past, installed Avahi? In particular, has anything messed with your /etc/nsswitch.conf file?

sweetthdevil · 2014-03-06 23:51:01

Thanks for your reply,

First of all I have avahi installed see pacman -Q and pacman -Rs below - it seem I must have it.

[sweetth@linuxbox ~]$ sudo pacman -Q avahi
avahi 0.6.31-11
[sweetth@linuxbox ~]$ sudo pacman -Rs avahi
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: gnome-vfs: requires avahi
:: gvfs: requires avahi
:: libcups: requires avahi
:: mono-zeroconf: requires avahi

And then my /etc/resolv.conf is pointing to my router for the DNS

# Generated by resolvconf
nameserver 192.168.1.86

For the other file - must admit I do not know it but here it goes.

# Begin /etc/nsswitch.conf

passwd: files
group: files
shadow: files

publickey: files

hosts: files dns myhostname
networks: files

protocols: files
services: files
ethers: files
rpc: files

netgroup: files

automount: files

# End /etc/nsswitch.conf

pacman -Qi avahi is all you needed.

ewaller · 2014-03-07 02:21:26

Your router is at 192.168.1.86? It seems odd, but I see that your gateway is set to that address as well. Could you please verify that with ip route ?
The nsswitch.conf file is okay, but it not properly configured to work with Avahi, but that is a different thread. I just wanted to ensure that dns was in the hosts line of that file.

Tell us a bit more about your network. What is it that is at 192.168.1.86? A computer?, router? A host for a virtual machine?
Is there a DNS server running at 192.168.1.86?

Anyway, your network is working, and this is a dns configuration problem.

sweetthdevil · 2014-03-07 09:03:07

Again thank you for your time and interest.

192.168.1.86 is my router (I know the address is unusual) The router is a Sky hub SR101.

I have Computer, Smart TV, Boxee Box and NAS on a wired connection. And then smartphones, tablet, Sky Box on the wifi.

See my netctl profile below:

Description='A basic static ethernet connection'
Interface=eth0
Connection=ethernet
IP=static
Address='192.168.1.95/24'
#Routes=('192.168.0.0/24 via 192.168.1.2')
Gateway='192.168.1.86'
DNS=('192.168.1.86')

## For IPv6 autoconfiguration
#IP6=stateless

## For IPv6 static address configuration
#IP6=static
#Address6=('1234:5678:9abc:def::1/64' '1234:3456::123/96')
#Routes6=('abcd::1234')
#Gateway6='1234:0:123::abcd'

Now I have tried to replaced the DNS on the above file to 8.8.8.8 but it didn't fix the issue.

What's get me is that nothing has changed - I only updated Arch...

sweetthdevil · 2014-03-07 11:49:01

Right,

Just realise that this issue is only happening on my linux account - on my wife or kids the wifi works.

sweetthdevil · 2014-03-09 12:26:39

Right,

So this is driving me nuts!

Since it only occurs on my account - I rename my .config folder but still the same. Looked at what programs are running and nothing it standing out.

So any suggestion would be greatly appreciated.

You mean, same pc, but depends on who logs in?

If that's the case you might have a weird program that's sending lots of weird packets on your network.
I know this is a longshot, but try installing wireshark, and look if you're creating any unusual trafic to ips that you shouldt.

sweetthdevil · 2014-03-10 11:14:12

You are a star!!!

I find the issue now - there is a bug in Pulseaudio - just surprise no more people are affected! see => https://bugs.freedesktop.org/show_bug.cgi?id=44777

Basically pulseaudio is broadcasting sound and this is overwhelming the wifi! No I have to find a solution....

sweetthdevil · 2014-03-10 17:08:45

Solved!!

First of all, thank you all for your time and help.

As my post above - the issue was cause by pulseaudio broadcasting the microphone sound through the network and denying services to the wireless connection by overwhelming the network!

To stop it, use paprefs and disable in the "Muticast/RTP" tab the Multicast/RTP Sender (I aslo disable the receiver - as I do not use it)

Arch Linux
