Nadzirate lahko do katerih programov je mogoče dostopati preko omrežja. To pomaga obdržati vaš računalnik varen.

# Omogočanje in blokiranje dostopa do požarnega zidu

GNOME does not come with a firewall, so for support beyond this document check with your distribution’s support team or your organization’s IT department. Your computer should be equipped with a firewall that allows it to block programs from being accessed by other people on the internet or your network. This helps to keep your computer secure.

Veliko programov lahko zagotavlja omrežne storitve. Na primer lahko souporabljate datoteke ali pustite nekomu, da si oddaljeno ogleda vaše namizje. Glede na to kako je vaš računalnik nastavljen, boste morda prilagoditi požarni zid, da bo tem storitvam omogočal delovanje.

Each program that provides network services uses a specific network port. To enable other computers on the network to access a service, you may need to “open” its assigned port on the firewall:

Go to Activities in the top left corner of the screen and start your firewall application. You may need to install a firewall manager yourself if you can’t find one (for example, GUFW).

Odprite ali onemogočite vrata za svojo omrežno storitev glede na to ali želite, da ljudje lahko do nje dostopajo ali ne. Vrata, ki jih želite spremeniti, so odvisne od storitve.

Shranite ali uveljavite spremembe in sledite morebitnim dodatnim navodilom orodja požarnega zidu.
