Can i safely disable NetworkManager connectivity check?

Support Network

i just read this article
https://linuxconfig.org/how-to-prevent-networkmanager-connectivity-checking

is it used for something else than “captive portal”?(if i understood correctly;it means i will not see login pages when connecting to wifi networks so i may not be able to login to them at all?)

i don’t move my laptop around and don’t use wi-fi,so can i safely disable it?
will i encounter any issues?
does it affect the time server settings as well the official repositories list?(saw someone mention it).

it seems that for my case it’s just a privacy concern:
form the Arch wiki: “Although automatic connectivity checks are a potential privacy leak, Arch Linux’s default connectivity URL is committed to not logging any access”

if it’s ok to disable it,what would be the right way to do it?

create /etc/NetworkManager/conf.d/20-connectivity.conf.

[connectivity]
uri=http://www.archlinux.org/check_network_status.txt
interval=0

sudo systemctl restart NetworkManager

or

/etc/NetworkManager/conf.d/20-connectivity.conf

[connectivity] 
.set.enabled=false

or maybe enabled=false

I am on Unstable branch and mine is set to ping manjaro.org. A good compromise is to set the interval higher eg:

uri=http://ping.manjaro.org/check_network_status.txt
interval=36000
or delete the file, or comment it out.

This is correct. See NetworkManager - ArchWiki

Thank you
i’ll try one of the mentioned suggestions.

@Yochanan
i saw that,but above there’s a comment:

" The factual accuracy of this article or section is disputed.
Reason: According to NetworkManager.conf(5) § CONNECTIVITY SECTION, the option is enabled=false not .set.enabled=false. (Discuss in Talk:NetworkManager#)"

or did you try .set.enabled=false and it worked fine?

enabled=false worked for me. I included the uri.

I used iftop to confirm.

Similar question here.

i went with interval=0

Yes - it is perfectly safe. The only caveat is that network manager cannot deduct whether you have an internet connection or not.

There is several methods to accomplish this

  1. change the righthand part to a trusted domain

or

  • remove the righthand part of uri
  • set interval to 0

I went with number 1

➜  ~ cat /etc/NetworkManager/conf.d/20-connectivity.conf 
[connectivity]
uri=https://iso.uex.dk/check_network_status.txt
interval=300

sudo nano /usr/lib/NetworkManager/conf.d/20-connectivity.conf
#[connectivity]
#uri=http://ping.manjaro.org/check_network_status.txt

but as I have never been bothered by a ping to manjaro or arch… I leave it as it is by default, that is to say without commenting the lines.

While this will work - it will be overwritten the next time network manager is updated - and you will think badly of the packager.

Never edit system files directly but copy the file to /etc/NetworkManager/conf.d and make the change there.
