Firewall Config: Wowonetsera bwino kwambiri wa Firewall m'malo mwa Gufw Firewall

M'munda wa ogwiritsa ntchito osavuta (nyumba / maofesi) zikafika pakugwiritsa ntchito Njira yogwiritsira ntchito zamtundu uliwonse, kawirikawiri, simuyenera kuchita zovuta kapena ukadaulo, monga, zosefera, kulumikizana ndi kutsegula kwa doko kapena kutsekereza, pakati pa ena.

Popeza mitundu iyi yazinthu nthawi zambiri imakhala pakati pa Makompyuta Makompyuta kudzera maseva ndikuwongolera mu makompyuta kwa Akatswiri a IT. Koma, wosuta akafuna kuti agwiritse ntchito izi, kuti asavutitse ntchito pakompyuta yake, pali zosavuta kugwiritsa ntchito monga "Kusintha kwa Firewall" y Gufw.

About Firewalls, GUFW ndi IPTables

Ndipo mwachizolowezi, tisanapite kwathunthu kumutu wa lero tidzasiyira iwo omwe akufuna kuti afufuze zam'mbuyomu zolemba zokhudzana ndi mutu wa Mawotchi, GUFW ndi IPTables, maulalo otsatirawa. Kuti athe kudina msanga ngati kuli kofunikira, akamaliza kuwerenga buku ili:

"Monga ma Linux distros, Ubuntu amabwera kale ndi chowotcha moto. Chowotcherachi, m'malo mwake, chimalowa mu kernel. Mu Ubuntu, mawonekedwe amtundu wamalamulo ozimitsira moto adasinthidwa ndikusintha mosavuta. Komabe, ufw (FireWall Yopepuka) imakhalanso ndi mawonekedwe owoneka bwino omwe ndiosavuta kugwiritsa ntchito. Mu positi iyi, tiwonetsa tsatane-tsatane kaupangiri kagwiritsidwe ntchito ka gufw, mawonekedwe a ufw, kukonza firewall yathu." Momwe mungasinthire firewall mu Ubuntu

Kukonzekera kwa Firewall: Chida chokhazikitsira GUI cha firewalld

Kodi Firewall Config ndi chiyani?

Zachidziwikire ma Linuxeros ambiri amadziwa kale Gufw. Koma kwa iwo omwe sakuzidziwa, ndi njira yosavuta yosavuta kuyang'anira makhoma otetezera amtundu wa Linux (Iptables), chifukwa imapereka mawonekedwe owonetsera (GUI) a pulogalamu ya firewall application (CLI) yotchedwa Oo. Ndipo mwazinthu zomwe mungachite nazo Gufw Ali, akuchita ntchito zofananira monga kuloleza kapena kutsekereza zomwe zidakonzedweratu, p2p wamba, kapena madoko amodzi.

Komabe, pali pulogalamu ina yayikulu yotchedwa "Kusintha kwa Firewall" yomwe patsamba lake lovomerezeka imafotokozedwa mwachidule motere:

"Ndicho chida chosinthira cha firewalld." firewall-config

Kukhala ntchito Firewalld chotsatira:

"Pulogalamu yothandizira (CLI) yomwe imapereka makhoma otetezera mwamphamvu mothandizidwa ndi maukonde / makhoma amoto omwe amafotokozera mulingo wodalirika wolumikizira ma netiweki kapena polumikizira. Imathandizira IPv4, IPv6 firewall masanjidwe, milatho ya ethernet, ndi maiwe a IP. Kuphatikiza apo, imakhazikitsa kusiyana pakati pa njira yothanirana ndi nthawi yokhazikika ndi yokhazikika, ndipo chifukwa chogwiritsa ntchito mawonekedwe a D-Bus, ndikosavuta kukhazikitsa ntchito, kugwiritsa ntchito komanso kwa ogwiritsa ntchito kuti asinthe mawonekedwe a firewall ."

Kuphatikiza apo, ndibwino kufotokozera izi Firewalld ndiye woyang'anira kutsogolo kwa Zolankhula, monga UWU, kokha, imagwiritsa ntchito magawo ndi ntchito m'malo mwa unyolo ndi malamulo. Ndipo imayang'anira magulu olamulira mwamphamvu, kulola zosintha popanda magawo ndi kulumikizana. Zotsatira zake, Firewalld sichilowa m'malo mwa Zolankhula.

Zida

Ena mwa iwo ndi:

1. Malizitsani D-Basi API
2. IPv4, IPv6, mlatho ndi ipset thandizo
3. NAT IPv4 ndi IPv6 thandizo
4. Madera ozimitsira moto
5. Mndandanda wokonzedweratu wamagawo, ntchito ndi zizindikilo
6. Chilankhulo cholemera pamalamulo osinthika komanso ovuta kumadera
7. Malamulo Omwe Amasungidwa Nthawi Yoyaka M'madera
8. Kutsekereza: Kuvomerezeka kwa mapulogalamu omwe angasinthe makhoma oteteza
9. Kutsitsa kwama module a Linux kernel
10. Kuphatikiza ndi Chidole

Njira Zina

M'munda wamaseva pali njira zingapo zogwiritsira ntchito, makina ndi magawidwe athunthu ndi mayankho olimba a Firewalls (Firewalls). Komabe, pankhani yazogwiritsa ntchito makompyuta ogwiritsa ntchito osavuta (osakhala aukadaulo), kuti muchite ntchito za zosefera timalimbikitsa kugwiritsa ntchito pulogalamu yothandiza komanso yosavuta yotchedwa "Wokonda Minder". Zomwe ndizosavuta kugwiritsa ntchito, chifukwa chake zimakhala zabwino kwambiri dongosolo lowongolera makolo (firewall) pazomwe timayamikira GNU / Linux Distros.

Mwachidule, kugwiritsa ntchito zonsezi "Kusintha kwa Firewall" Como Gufw kusamalira Zolankhula (native linux kernel firewall) momveka bwino pa iliyonse GNU / Linux Distro pomwe phukusi lawo limakhazikika kapena limagwirizana ndi njira yabwino yofufuzira. Koposa zonse, kwa iwo omwe akuyamba kumene ndipo alibe chidziwitso chambiri chaukadaulo (terminal) kuti achite ntchito za zosefera, kulumikizana ndi kupanikizana kwa doko kapena kutsekereza, mwa zina zaluso.

Tikukhulupirira kuti bukuli lithandizira lonse «Comunidad de Software Libre y Código Abierto» ndikuthandizira kwambiri pakukweza, kukula ndi kufalikira kwachilengedwe cha ntchito zomwe zapezeka «GNU/Linux». Osasiya kugawana ndi ena, mumawebusayiti omwe mumawakonda, mayendedwe, magulu kapena magulu azamawebusayiti kapena makina amtokoma. Pomaliza, pitani patsamba lathu kunyumba «KuchokeraLinux» kuti muwone zambiri, ndikulowa nawo njira yathu yovomerezeka Telegalamu yochokera ku DesdeLinux.
