Questions[network-monitoring](ubuntu)

For the past 5 years, I have been using Ubuntu 14.04 LTS. During that time, I didn’t face any unwanted internet data consumption issues. Recently I installed Ubuntu 20.04 LTS. I haven't installed any other software yet. I configured auto update settings as below. Ubuntu 20.04 software & update settings

Even after the above settings, Ubuntu 20.04 consumes around 1 GB of internet data within a few minutes in idle state (not browsing anything). I am using Wi-Fi hotspots internet data from mobile. Please help guide me to stop this huge unintended consumption of internet data by Ubuntu 20.04. Thanks.

I am trying to install nagios but I would like to start the web interface on a port other than 80. I cant seem to find much info on how to do that. Any help is appreciated. Thanks

i have installed nagios and i want to install nrpe. While installing NRPE, when i execute (/home/abc/nrpe/configure)

./configure

it stops after reaching the following line

...

checking for type of socket size... size_t
checking for SSL headers... SSL headers found in /usr
checking for SSL libraries... configure: error: Cannot find ssl libraries

I have installed libssl-dev and openssl package as i found them as a solution for this error.

I tried the following option also

./configure --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib

But the error remains.

What can be the possible solution for this ? I am using ubuntu 12.04 as my operating system. Thanks in advance.

I am looking for a script or a tool which I can turn on, when needed, which shuts down my computer if there is e.g. no network traffic for say 10 minutes, or below 100kb for example.

Would be really handy for automatic downloading. I know there are downsides to this, internet connection is hanging, download program is hanging, so if you have a better idea, please tell me.

Thanks in advance.

I was wondering if I deploy a server at home, with apache2. I would like to know how much traffic is currently on my site, in real time.

Please and thank you.
