I use fedora 14, and when I start system monitor, i can see that it already downloaded 40 Mb, without doing anything. How can i stop programs that secretly consume my bandwith? I use a prepaid modem with limited bandwith (500 Mb). I guess yum is consuming some bandwith with updates checking and downloading the xmls

Try to investigate what's happening with nethogs.

Also there are tcpdump, wireshark, iotop.

If you determine that yum is the culprit, you may want to raise the value of metadata_expire in /etc/yum.conf. This is the TTL for the yum metadata. Raising it should cause yum to fetch less frequently.

Installing yum-presto will use delta RPMs for updates (this may be the default now?), which will be smaller than the standard RPMs.

You may want to run /usr/bin/gpk-prefs and turn down the frequency of checking for updates from daily to weekly.
