Constant network activity | "Unknown" connections established

Hi everyone,

I am looking for some help regarding some "unknown" connections that are being established. That is a problem for me because I have a download limit of 5Gb per month and those connections seems to downloads some stuff that I don't know what it is.

I did a netstat and here's some addresses:

tcp 0 0 asdf:56739 mirror.nexicom.net:http TIME_WAIT -
tcp 0 0 asdf:46892 linux00ss.unity.nc:http TIME_WAIT -
tcp 0 0 asdf:47676 coggsworth.cse.buf:http TIME_WAIT -
tcp 0 0 asdf:58033 fry.wallawalla.edu:ftp ESTABLISHED -
tcp 0 0 asdf:39970 mirrors.med.harvar:http TIME_WAIT -
tcp 0 0 asdf:53545 chernabog.cc.vt.ed:http TIME_WAIT -
tcp 0 0 asdf:45102 mirror.metrocast.n:http TIME_WAIT -
tcp 0 0 asdf:38167 white.web-ster.com:http TIME_WAIT -
tcp 0 0 asdf:56629 mirror.nexicom.net:http TIME_WAIT -
tcp 0 0 asdf:40938 mirror.cogentco.co:http TIME_WAIT -
tcp 0 0 asdf:57807 mirror.nexicom.net:ftp ESTABLISHED

Looks to me that the one established might be something related to updates. So I've disabled the Software updates in Software settings. But still having those connections.

If I look in System monitor and look for Network history, there has been for about 200Mb of downloads. Yesterday, for about 600Mb...my limit is now over of 2Gb!

Any help to diagnose this problem would be appreciated and for your information, I'm using Fedora 17.

Thanks a bunch,

They're Fedora mirror servers, try disabling automatic updates and see what happens.

Re: Constant network activity | "Unknown" connections established

I think it did the job!

Here's what I had to do in Terminal (logged as root):

- run gpk-prefs;
- make sure everything is set to Never or Disable.

I will run my updates manually once a month.

Also, I noticed that if I use the Software Updates via Application - System Tools, I had to disable everything again. It looks like those settings are user-based (correct me if I am wrong).
