I-Firewall ku-Ubuntu

Izolo sikhulume nawe ngezokuphepha ku Ubuntu, besikhuluma ngayo i-antivirus ku-Gnu / Linux nokuthi ungayisebenzisa kanjani njengethuluzi lokuphepha.

Hhayi-ke, ngiyabona ukuthi amagciwane akuyona ukuphela kwengozi ekhona ezweni lamakhompyutha nokuthi izikhathi eziningi ukungena kwabanye abantu ohlelweni lwethu kuyingozi kakhulu kunegciwane elibhalayo I Love You esikrinini sethu. Ngalokhu kunethuluzi elinamandla kakhulu abantu abaningi abalisebenzisayo nabalaziyo i-firewall noma i-firewall.

Kepha kukhona izibhulamlilo ku-Ubuntu?

Zonke izinhlelo ezisebenzayo zinezikhuni zomlilo, ngoba ziyimithetho elula ephethe ukuqondisa kabusha ithrafikhi yolwazi lwangaphandle ohlelweni lwethu lokusebenza. Ngakho-ke ku Ubuntu Ifakwe kahle ngokuzenzakalela ngezinguqulo eziningana, ngicabanga ukuthi ngiyakhumbula ukuthi ifakiwe kusukela kwinguqulo 7.04. Futhi uzongitshela ukuthi unenguqulo yakamuva kepha awuboni firewall. Incazelo ilula, i-firewall ye- Ubuntu Ayinaso isikhombimsebenzisi sokuqhafaza futhi iphethwe kuphela yikhonsoli.

Lokhu ekuqaleni kube nesiphithiphithi kubasebenzisi abaningi, ngakho-ke ngesikhathi esifushane kube nesixazululo futhi isikhombimsebenzisi sokuqhafaza senzelwe labo basebenzisi abasifunayo. I- i-firewall ku-Ubuntu ibizwa nge-Ufw, uma kwenzeka othile eba nesibindi sokuyisebenzisa ekugcineni. Futhi isikhombimsebenzisi sokuqhafaza kubizwa Gufw, kufakiwe ezinqolobaneni ze- Ubuntu ukuze ukwazi ukuyifaka ngokusebenzisa i-terminal noma nge Ubuntu Software CenterUngasesha ngisho nephakheji bese uyilanda njengakuqala.

Uma ifakiwe ukuphatha kulula.

Into yokuqala okufanele uyivule nge-password izimpande ukwazi ukuphatha naye. Imvamisa ngokuzenzakalela i- Hewu icishiwe ngakho-ke kuzofanela uyisebenzise.
Uma sekusebenze, ukumiswa okujwayelekile kuyalayishwa okuvumela konke okuphuma kwikhompyutha kuye kwi-Intanethi kepha akukho okufakwayo okuvela ngaphandle kuya kwi-Intanethi, okungukuthi, ungazulazula ngokuphepha ngoba ngeke bakwazi ukusebenzisa i-pc kusuka ngaphandle. Ungakha futhi imithetho lapho usho khona ukuthi ikuphi okufakwayo okuvumelayo nokuthi kuphuma ini. Imvamisa okokufaka nemiphumela ilawulwa ngamachweba, maningi futhi uhlelo ngalunye lusebenzisa oluhlukile. Ngakho-ke i-emule noma i-amule isebenzisa i-4662 ne-4672 ngokuzenzakalela ngenkathi i- Tukudluliswa sebenzisa imbobo ehlukile.

Ukwakha imithetho kufanele ucindezele uphawu "+" bese kuvela iwindi izinkophe ezintathu ezincane ukukhetha indlela yokwenza umthetho.

Kusuka Simple, ungakha imithetho yetheku elizenzakalelayo. Lokhu kukuvumela ukuthi wakhe imithetho yezinsiza nezinhlelo zokusebenza ezingatholakali ku- Kulungiselelwe ngaphambilini. Ukulungisa uhla lwamachweba, ungawabeka usebenzisa i-syntax elandelayo: NROPORT1: NROPORT2.
Kusuka Kuthuthukile, ungakha imithetho ecacisiwe usebenzisa amakheli we-IP womthombo nendawo oya kuyo namachweba. Kunezinketho ezine ezitholakalayo zokuchaza umthetho: vumela, uphike, uphike, futhi ubeke umkhawulo. Ukwenqaba kuzobuyisa umlayezo «I-ICMP: indawo okuyiwa kuyo ayifinyeleleki»Kumfakisicelo. Umkhawulo ukuvumela ukuthi ukhawule inani lemizamo yokuxhumeka engaphumelelanga. Lokhu kukuvikela ekuhlaselweni ngamandla. Uma umthetho ungeziwe, uzovela ewindini elikhulu le- Hewu.

Futhi-ke uzobe usulungiselele futhi walungisa ifayela lakho le- i-firewall noma i-firewall. Ithuluzi elibaluleke kakhulu olikhumbulayo lingakuphendukela, ngoba uma ungakhumbuli i-firewall noma amachweba avaliwe noma avuliwe, kungavela inqwaba yezinkinga. Uzongitshela.

    Kade ngizama ukuyisebenzisa izinyanga ngilandela zonke izinkomba abazishoyo, hhayi kule ndatshana kuphela kodwa nakwezinye eziningi ezisenetheni, futhi ngicabanga ukuthi ukuphela kokusatshalaliswa okusebenza kahle ku-OpenSUSE, okunye kokunye; kuthatha isikhathi eside ukuyenza isebenze futhi uyihlele kunokuyeka ukusebenza.
