I am monitoring my network interface and noticed that I can reproduce a behavior where some cryptic DNS packets are being sent out as well as TCP sometimes, without me opening any browser or application for that matter.
All I have to do is turn off WIFI and then turn it back on. Then a number of DNS packets are sent out automatically.
Here is the cap file:
This doesn’t strike me as normal behavior, why are DNS packets being sent out?.. Upon following the TCP packets I noticed that they are being sent to an EC2 instance on AWS.
I have recently installed Ubuntu 19.04 in my Lenovo ideapad along with windows 10 .
I could not found how to turn on WiFi even I could not get anything like ” No WiFi adapter found ” something like that.

I’ve bought a new laptop. I’ve installed ubuntu 18.04.3 . All went well except wifi signal, it’s weak and slow. I’ve tried several commands on terminal for knowing which wifi adapter it has, but only could see it uses a generic driver. What can I do? Thanks a lot.
I was installing selenium for my PC which requires chromedriver. initially chromedriver wasn’t working so I looked for potential solutions and I remember updating chrome and doing something with libnss3 library..I think I ran some random command off a site (mistake on my part)…. I got it to work somehow and my net was working. The PC got screen-off’d after some time and net had stopped working. The top bar which shows WiFi icon is also misbehaving..it says connected in the drop-down menu but not on the top WiFi icon on top of screen.
Things I’ve tried:
-I tried 2 wi-fi’s..both not working – my phone WiFi hotspot works but only for google. YouTube and Facebook, I can do searches but can’t open any sites – I messed up my settings by trying to troubleshoot myself. I changed resolve.conf files I messed up interfaces etc (I only edited the text files related to internet settings..nothing else) – my laptop has windows dual boot and the WiFi is working perfectly there..so it’s definitely a Ubuntu issue – restarted rebooted both modems and PC – closed network manager and reopened via terminal – I also have a usb WiFi card…which I used but I’m not able to connect..only way I can get net to work is from my hotspot( only google.com) -tried changing DNS
I think that the issue is related to the libnss3 library or chrome update…
ifconfig -a gives 3 cards -enp9s0 -lo -enp9s0 This is with no external usb WiFi If I add WiFi card it shows up in ifconfig
sudo lshw -C network Output – -network disabled Description:wireless interface – network disabled Description : ethernet interface
The wireless interface wasn’t showing disabled before I posted this question..so I guess I messed it up even more…
Lspci shows my driver
IMO it’s a configuration issue which I messed up badly..I’m working on an URGENT project where I can’t just reinstall Ubuntu..please help me fix it without resetting my Ubuntu
I’m posting from phone as no internet on PC so please don’t mind the formatting and code outputs I’m willing to run any command you guys need for debugging purposes ls help
We are hosting a simple website locally and it has completely separate networking i.e., IP, gateway etc. When we connect via LAN website is accessible but when we connect through a wifi point, it fails and even browser says “This site can’t be reached”. I have to inspect this issue. All systems are Ubuntu based. Following is the output of host command (domain name changed)
use1@use1:~$ host -d example.com Trying "example.com" Host example.com not found: 2(SERVFAIL) Received 33 bytes from 127.0.0.53#53 in 13 ms
use1@use1:~$ ping example.com ping: example.com : Name or service not known
But if I do on LAN I get correct output i.e., Live IP information is given. Out wifi point is on same network. How I can inspect this issue. What are the tools and methods for this purpose. Can I inspect this real time in browser chrome or firefox ?
I’m using Ubuntu 19.04 on my new laptop and I was able to successfully connect to some networks. Some of them however won’t let me connect. I can select them but as soon as I press connect it just crashes. The only thing I can think of that is noteworthy about these networks specifically is that they require an email and password rather than just a password like a home network. Might be unrelated but twice an error message telling me that something went wrong with gnome-control-center also came up around the time that it crashed due to this.
I just installed ubuntu on my HP laptop, dual boot windows 10 i cant connect to wifi cuz wifi adapter is not found and i cant install git
