But no  /etc/resolv.conf. No file, no symlink.

 

It is created by openresolv, when the network is started (or restarted).

 

It is not the task of Enigma to meddle in linux network services.

 

Yes it does exist. Looked over it.

[Mr.Yoshi!]

hey ! maybe you can regulate that in the nfsroot! mac can actually be changed with it, but mac can also be used with a script and in the interface! maybe it works with nfsroot the dns! just a suggestion is actually the mac address then to change in the nfsroot!

# In case the interface is used as nfsroot, avoid ifup, otherwise # nfsroot may lose response if [ "$IFACE" = "eth0" ]; then /sbin/ifconfig eth0 hw ether 00:00:00:00:00:00 fi exit 0

P.s. DNS 1.1.1.1 is better than 8.8.8.8 Google

Problem is elf.ifaces["eth0"]["dns-nameserver"] doesn't update with defined nameservers.

 

self.nameservers is only written to /etc/resolv.conf.,

 

I use this patch for now.

[Beeker]

 

One problem found in network.py
dns-nameserver must be dns-nameservers.

In fact, for several nameservers, the correct format is:

dns-nameservers 8.8.8.8 4.4.4.4

Not multiple lines with dns-nameservers, as suggested in the code.

 

 

Like this.

+					if iface["dns-nameserver"]:
+						fp.write("	dns-nameservers")
+						for nameserver in iface["dns-nameserver"]:
+							fp.write(" %d.%d.%d.%d" % tuple(nameserver))
+						fp.write("\n")

Need to update the reading code as well.

Even with openresolv installed, after restart the file resolv.conf in /var/run is empty.

If i manually put the line "dns-nameservers 192.168.1.1" in interfaces, then after restart all is OK. The file resolv.conf contain:

# Generated by resolvconf

nameserver 192.168.1.1

[Dimitrij]

If wait until the end of the week, I will write the required code.

I started doing it.

Even with openresolv installed, after restart the file resolv.conf in /var/run is empty.

If i manually put the line "dns-nameservers 192.168.1.1" in interfaces, then after restart all is OK. The file resolv.conf contain:

# Generated by resolvconf

nameserver 192.168.1.1

 

That indeed is the current workaround if you require a fixed DNS.
 

[foxbob]

For example I set dns-dhcp enable:

nameserver 208.67.222.123

nameserver 208.67.220.123

 

And after the restart of the gui and a complete reboot the dns does not disappear.

And if I set dns 1.1.1.1 or 8.8.8.8 after restart, gui dns is not saved.

Where do you set dns?

It has already been stated here that without code corrections, fixed dns setting via GUI does not work.

You need to manually edit the file  /etc/network/interfaces and after restart the receiver.

[foxbob]

It is already clear that the dns change does not work through the gui.It's just not clear why some dns settings through gui work, while others don't.

 

And even earlier if I chose a wlan then when setting it up, it was suggested to turn off the lan, but now this is not the case.Or is it just me.

It's just not clear why some dns settings through gui work, while others don't.

And now, maybe only for me, when choosing a wlan and setting it up, it does not offer to disable another interface.

In the case of dns from dhcp, you don't need to save or read anything and that's why it works.

 

openresolv is a resolvconf implementation. It will take the DNS information retrieved from dhcp and populate /etc/resolv.conf with it.

 

For DNS information entered manually, that issue was brought up by WanWizard and is hopefully on the way of being solved now.

 

( static DNS has to be confgured in /etc/network/interfaces, openresolv will use those too when populating resolv.conf )

[Taapat]

On the current openpli-develop on receiver Gigablue UHD UE 4K with fixed IP and DNS I observed very slow internet.

For example, opkg update takes at least 1 minute to download package information.

If I switch to openpli-8.3 in multiboot, there are no problems with internet speed.

Then you've restored a /etc/resolv.conf, or deleted the symlink that is there after a flash and replaced it by a fixed file.

[Taapat]

I can't reproduce that, the response here is direct.

I found that the problem is when I set as primary DNS my Mikrotik router which cached DNS records. Router dns cache flush doesn't help either.

If I set, for example, Cloudflare as primary, then there is no problem.

So far I have not observed anything like that.

I run a PiHole as local DNS. I have a fixed IP and fixed DNS in my /etc/network/interfaces, pointing to it.
