The moment I start the hotspot my internet stops about hotspotd

[prahladyeri]

The error comes on the host machine of the AP? Which means internet works ok on your mobile phone that connects to AP or it doesn't come there too?

I think you have got two wifi interfaces - one you are using to connect to internet, and second is used by hotspotd to create the AP. Please confirm if this is true?

[konsbn]

No the DNS error is on both the mobile device and the Host Computer. I am using Ethernet to connect to the internet. I am not using wifi to access internet.

[konsbn]

Please help?

[prahladyeri]

hotspotd depends on dnsmasq for DNS resolution and address provisioning, do you have it installed on your system? Check by running dnsmasq -v.

If its not installed, then install it and try again. If its already installed, then reinstall the package and try again.

[konsbn]

I have dnsmasq installed.

It used to work fine on ubuntu 14.04 when I reinstalled elementary it's giving me trouble

[prahladyeri]

Can you show me the console output of hotspotd when you start it?

[konsbn]

It starts normally and doesn't throw any errors. I can connect to the hotspot but I get DNS error on both my android and on Ubuntu

[prahladyeri]

In that case, it appears to be some kernel/OS level issue introduced in elementary. Try to raise this with elementry support and provide them with the output of /var/log/syslog to trace the DNS issue.

[konsbn]

Is there nothing I can do meanwhile? Because everything is the same it used to work on 14.04.

[konsbn]

Here is the out put of cat /var/log/syslog log.txt On a side note even though my internet doesn't work after start hotspotd my torrent client is working just fine with downloads.

[prahladyeri]

On a side note even though my internet doesn't work after start hotspotd my torrent client is working just fine with downloads.

That sounds very much like a firewall issue to me. Check your firewall settings using sudo iptables -L and other methods of Elementary OS.

edit

Especially check that outgoing UDP port 53 and TCP ports 80 & 443 are open. The former should be open for DNS and latter for Internet browsing.

[konsbn]

I tried sudo ufw allow 53/udp and 'sudo ufw allow 80/tcpand 'sudo ufw allow 443/tcp. Still no change the DNS error keeps propping up. Here is the output from sudo netstat -ntlp | grep LISTEN
```➜ ~ sudo netstat -ntlp | grep LISTEN

What happens when you run the following command manually?

ifconfig <wlan> up IP <ipaddr> netmask 255.255.255.0

Replace <wlan> with your wifi interface and <ipaddr> with your ip-address?

[konsbn]

This-
➜ ~ ifconfig wlan0 up IP 103.37.201.63 netmask 255.255.255.0
SIOCSIFFLAGS: Operation not permitted
IP: Host name lookup failure
ifconfig: --help' gives usage information.`

[prahladyeri]

You've got a much larger networking issue with ifconfig not working as it should be 😄 . Try to get this resolved first from the Elementary team first.

Basically, this is what hotspotd does internally first - try and bring up your wifi interface so it can create the ap. As a workaround, try running this command first and then hotspotd using sudo and see if that helps.

[konsbn]

damn, what it should be doing? and what could I do?

[prahladyeri]

It should not be saying Operation not permitted if everything works properly. As I said, try running hotspotd in sudo mode and try raising the ifconfig issue with elementary team. Those are the only things you could presently do.

[konsbn]

using sudo ifconfig wlan0 up IP 103.37.201.63 netmask 255.255.255.0 gives me IP: Host name lookup failure

[konsbn]

There's no response on elementary OS stack exchange

[prahladyeri]

Elementary is buggy and gets even buggier when you try to customize or use less used features like dns servicing or hostapd. Refer to below article for a discussion on this:

https://www.reddit.com/r/linuxmasterrace/comments/3y2cfo/ubuntu_vs_elementaryos_vs_linux_mint_cinamon_vs/

Might I ask why do you want to use Elementary instead of Ubuntu?

[konsbn]

Because I am an idiot that's why I thought maybe I should give elementary a try. Plus I tried ubuntu 16.04 but I couldn't ger driver:brcmsmac to work. so yeah.

[prahladyeri]

16.04 isn't quite ready for the show yet, it will be once 16.04.1 comes out. Until then, stick with Ubuntu 14.04 LTS - proven and time-tested.

[konsbn]

I am tired of this shit. Ubuntu is moving away from desktop computing and No other good replacement is available.

[prahladyeri]

How about Debian and Fedora? There is also Linux Mint, all are desktop oriented.

[konsbn]

I do not like fedora's package manager. And I don't know maybe I am too used to ubuntu based systems

[konsbn]

What do you use?

[prahladyeri]

If you are used to ubuntu based systems, you can certainly handle Debian Stable and also Linux Mint. Try either of them, they are mainstream so you won't have any issues. More importantly, their support forums are good, so you usually receive quick replies.

[tchaler2017]

I am getting the same error as Konsbn, DNS error is on both the mobile device and the Host Computer. when i tried this command ifconfig up IP netmask 255.255.255.0 the result is:
