What are these unknown unauthorised network connections?

rated 0 times [ 2] [ 0] / answers: 1 / hits: 763 / 2 Years ago, fri, june 17, 2022, 9:11:44

As soon as i start the computer it connects to a lot of different connections over internet, even when I haven't opened the browser. The screenshot from etherape is attached for better understanding

My internet connction has slowed down in the last few days so i checked and found these connections
I am using ubuntu 12.04.

Does it mean my ubuntu installation is affected by some malware / virus

or is it ok to have such connections?

Does it affect my internet connection speed?

You can also know what program is launching those connection using this command

sudo netstat -tup

It will give you something like this

Active Internet connections (w/o servers)

Proto Recv-Q Send-Q Local Address           Foreign Address         State           PID/Program name    

tcp        0      0 mypc:55541              db3msgr5011103.gat:msnp ESTABLISHED     4884/pidgin         

tcp        0      0 mypc:59350              we-in-f16.1e100.n:imaps ESTABLISHED     2919/thunderbird

In this example you can see pidgin and Thunderbird open some connections.
