Suspicius TCP Connections in Porteus 5.01 Fresh Install

Sub:- Suspicious TCP Connections in Proteus 5.01 Fresh Install
I have done a Proteus 5.01 Fresh Install as I wanted to try it out as email checking only as it is a secure distro
as per it's reputation. I have downloaded Firefox 133.0.3 from its browser tools from porteus server and update the
distribution from Porteus updater Tools.
But surprisingly while i only checking my emails [without opening any other website, Just gmail TAB in Firefox, no other site has opened after install - only Gmail], I have notice the following via netstat:-
[Facebook] + [Microsoft Azure @ Korea ISP + Web hosting] + [ISP CloudFlare DataCenter/Web Hosting/Transit US] + [Microsoft Corporation] + [Verizon Business] and Lots lots of different google server are connected!!!!!!!?????
Why there is some "Facebook", Microsoft or Verizon Business connection when I am only browsing my Gmail ???!!!
Pl. somebody care to explain?

Pl. note I am a user of Endeavouros also. I have attached my netstat result at the end for endeavouros for the same actions.
It is only google servers and nothing else!

I have attached my netstat result for ready reference :-
Gmail Session:-
30.5 MB Download 29.0MB Upload. [I did not Upload or download any attachment, Only text]

hi welcome to porteus forum

disclaimer: i am by no means a network security expert ..far from it.
1. do you have porteus firewall on? (it's off by default > see menu>system>porteus settings centre>security(padlock icon)>porteus firewall >toggle will turn on "normal" <usually enough.)
2. could be that the firefox binary from mozilla which our module is made with is 'looser' than endeavour's compilation ..take a good look at firefox's settings.
3. does your endeavour firefox have any active addons? ie. ublock, noscript or similar..
4. which DE flavour are you using? pretty sure none of them have any telemetry active (not that any of those entities suggest that)
5. i certainly haven't (knowingly) enabled anything nefarious and it seems unlikely anything like that would come from upstream (slackware)

Sub:- Suspicious TCP Connections in Proteus 5.01 Fresh Install

Hi hosico

Tipicaly Firefox uses a lot of connections with servers like Amazon, Cloudflare, Micro$oft etc, some of them for their services and some of them to fund themselves.

To see exactly which program uses connections, try this 'netstat' commands:

Code: Select all

netstat -ap | grep http

or

Code: Select all

watch netstat -ntpu

Wow! - I forgot I had been using the Porteus Firewall in Strict-mode for months! And zero problems.

Normally I don't run it, since I'm a home user behind a router's internal firewall, and no special ports need be opened. Perhaps I'll just leave it on.

Yeah, the other stuff mentioned in the browser - use extensions like Duck-Duck Go, Ublock-Origin (or ublock lite for Chrome), EFF's Privacy-Badger etc. STILL, that doesn't block all as time moves on. Sadly, some have to be there... Still better than nothing.

But this isn't about that! It's not hurting me, so with my simple setup, I'll leave the Porteus Firewall activated in strict.
