Network slowness

#1

Beitrag von zebulon7 »

Hi everybody.

Since a few updates, I notice big slowness in the accesses to my network.

My vu+ is connected by wifi to my Orange box, on the ground floor, which accesses my NAS, located upstairs.

The organization is as follows: vu+ -> wifi -> box -> cpl (ground) -> cpl (upstairs) -> switch -> nas.
(The cpl are TP-LINK TL-PA8030PKIT 1200 Mbps)
(The switch is a Netgear GS108T or a GS108)
Everything works very well when I access my nas by phone (android), pc (W10) or chromebook.

Only vu+ with the last Open ATV is problematic.
I make all updates when they are available.

This results in great slowness to access the bookmark of my nas and to circulate between the different directories of the nas.
I have the hourglass running long enough to end up accessing the chosen directory

Is it possible to do something?

Look in the adapter settings, perhaps DNS.

Impossible to find where i can modify the dns in OpenATV.
Perhaps it's possible directly in a file ?

Here is what I have and I must admit that I find the primary dns strange.:

DHCP = off -> user is responsible for ALL settings in his network.
Adjust the settings in ALL participiants right, and it will run smooth.
Whatever neccessary may be for YOUR environment.

Of course but it's OpenATV who put these DNS there, not me.
I just searched my wifi network and selected a fixed IP address as I did on OpenPLi.

But there is nowhere where we can change the DNS in OpenATV

dhcp off is not a good plan
Many internet modems block traffic from IP numbers that do not have a DHCP lease.
pli has/had problems with downloads with its download server

So ?
I have left PLi for my Duo4KSE for ATV.
But, as i said, since a few updates, the access to my network is so slow.

Hi.

You can also disable IPv6 with the following procedure: Disable IPv6 Networking on Linux Servers

In short... how to check the presence of IPv6:

A.) execute the following command:

Code: Alles auswählen

ip a | grep inet6

B.) in case you find the following as the result, then IPv6 is enabled:

Code: Alles auswählen

inet6 ::1/128 scope host
inet6 fe80::e922:bcdf:e150:labb/64 scope link


In short... how to disable the IPv6 in Linux:

1.) open the "/etc/sysctl.conf" file (use the text editor at your PC via the FTP connection ...or... use the vi / vim editor via temrminal connection)
2.) add the following two lines:

Code: Alles auswählen

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

3.) reboot your set-top box
4.) check the presence of IPv6 again (step A + B)

To identify what this IPv6 address is (as long as you have not turned off IPv6 support) you can use the following command:

Code: Alles auswählen

nslookup 2a01:cb04:97e:40              # nslookup <ip_address>

..or..

Code: Alles auswählen

traceroute 2a01:cb04:97e:40

Hi, thank you for your answer.
I will try this asap.

Could you tell me the password for telnet root ?

I added these 2 lines at the very end of the file.
Will it be good?

Steps 3 and 4... Just reboot and check, if your box still has an IPv6 address or not...

Yes, I have the same problem with the Internet. I thought the problem was in my box, but apparently the problem is in the open atv image.

@s3n0, @RickX

I did everything and after the reboot, nothing changed.
The primary DNS address has not changed, as in the photo attached at the beginning of the topic.
However, the statement "ip a | grep inet6" does not return anything after the restart whereas before it indicated the same kind of information that you gave as an example.

So, what else can I do?

PS : In the file "resolv.conf", i have this :

Code: Alles auswählen

domain  home
search  home
nameserver 2a01:cb04:97e:4000:5239:2fff:feef:d100
nameserver 192.168.1.1

Yes, i think too, it's from the OpenATV image.

@zebulon7

I'm not interested in the configuration file "resolv.conf" :-) , so... try this:

Code: Alles auswählen

ip a | grep inet6

You shouldn't see anything there for IPv6.

The availability of IPv6 networks can also be checked via the [font=courier new]ifconfig[/font] command.

It is also possible to turn off IPv6 support in the settings of your WIFI router. Then your set-top box probably won't get DNS with the IPv6 version. Try to find out, as I wrote, what this IPv6 address belongs to. What is this DNS server?

A reboot may not be sufficient in the case of a set-top box with Enigma installed. Also use the "restart network" function in the Enigma2 GUI - in the case of OpenATV it is:
blue button -> network -> restart network

The Internet gateway is also a common problem. If you use a VPN network, maybe the connection through this VPN gateway is preferred and then EVERYTHING is slower !!!

@zebulon7:
looks like crap in the /etc/resolve.conf
So slow searches and access is normal, when routing is disturbed by misrouting....

Ok, but what should I change then?
For information, in my Windows 10, i have :
Serveur DNS préféré : 1.1.1.1
Serveur DNS auxiliaire : 1.0.0.1

The statement returns nothing, so I guess the IPV6 is disabled, right?
