I-Firewall kwi-Ubuntu

Izolo besithetha nawe malunga nokhuseleko kwi Ubuntu, besithetha ngayo unqulo kwi-Gnu / Linux kunye nendlela yokuzisebenzisa njengesixhobo sokhuseleko.

Ewe, ndiyayiqonda into yokuba intsholongwane ayisiso kuphela isoyikiso esikhoyo kwikhompyuter kwaye amaxesha amaninzi ukungena kwabanye abantu kwinkqubo yethu kuyingozi kakhulu kunentsholongwane ebhalayo Ndiyakuthanda Kwiskrini sethu. Kule nto kukho isixhobo esinamandla kakhulu abantu abaninzi abasisebenzisayo kwaye basaziyo i-firewall okanye i-firewall.

Kodwa ngaba kukho umlilo kwiBuntu?

Zonke iinkqubo ezisebenzayo zinezixhobo zokucima umlilo, ngenxa yokuba yimithetho elula ejongene nokuhambisa kwakhona ulwazi lwangaphandle lwezithuthi kwinkqubo yethu yokusebenza. Ke ngaphakathi Ubuntu Kufakwe kakuhle ngokungagqibekanga kwiinguqulelo ezininzi esele zikho, ndicinga ukuba ndiyakhumbula ukuba ibifakiwe ukusukela kwinguqulelo 7.04. Kwaye uya kundixelela ukuba unenguqulelo yamva nje kodwa awuboni firewall. Kulungile inkcazo ilula, i-firewall ye- Ubuntu Ayinayo imbonakalo yomzobo kwaye ilawulwa kuphela yikhonsoli.

Oku kwaqala ukuba nesiphithiphithi kubasebenzisi abaninzi, ke ngexeshana elifutshane kukho isisombululo kwaye ujongano lomzobo lwenzelwe abo basebenzisi abalifunayo. Inkqubo ye- I-firewall ku-Ubuntu ibizwa ngokuba yi-Ufw, ukuba umntu othile angazama ukuwusebenzisa kwisiphelo sendlela. Kwaye ujongano lomzobo ibizwa Gufw, Ifakiwe kwiindawo zokugcina ze Ubuntu ke unokuyifaka kwisiphelo sendlela okanye ngokusebenzisa IZiko leSoftware UbuntuUnokukhangela iphakheji kwaye uyikhuphele njengangaphambili.

Xa sele ifakiwe ukuphatha kulula.

Into yokuqala ekufuneka uyivulile kunye negama eligqithisiweyo Ingcambu ukuze ndikwazi ukusingatha naye. Ngokwesiqhelo ngokungagqibekanga ifayile ye- Wowu icinyiwe ngoko ke kuya kufuneka uyenze isebenze.
Nje ukuba isebenze, ulungelelwaniso oluqhelekileyo lulayishiwe oluvumela zonke iziphumo ezivela kwikhompyuter ukuya kwi-Intanethi kodwa akukho galelo lisuka ngaphandle liye kwi-Intanethi, oko kukuthi, unokuhamba ngokukhuselekileyo kuba abayi kuba nakho ukuqhuba i-pc ngaphandle. Unokwenza imigaqo apho utsho khona ukuba ngawaphi amangenelo owavumelayo kwaye aphumayo. Ngokwesiqhelo igalelo kunye neziphumo zilawulwa ngamazibuko, zininzi kwaye inkqubo nganye isebenzisa eyahlukileyo. Yiyo loo nto i-emule okanye ikhubalo lisebenzisa i-4662 kunye ne-4672 ngokungagqibekanga ngelixa i Tukuhambisa sebenzisa izibuko elahlukileyo.

Ukwenza imithetho kufuneka ucofe uphawu "+" kwaye iwindow iya kuvela nayo iinkophe ezintathu ezincinci ukukhetha indlela yokwenza umthetho.

Ukusuka Elula, Unokwenza imigaqo yezibuko elingagqibekanga. Oku kukuvumela ukuba wenze imigaqo yeenkonzo kunye nezicelo ezingafumanekiyo Kulungiselelwe kwangaphambili. Ukucwangcisa uluhlu lwamazibuko, ungazicwangcisa usebenzisa is syntax elandelayo: NROPORT1: NROPORT2.
Ukusuka Advanced, Unokwenza imigaqo ethe ngqo ngakumbi usebenzisa iidilesi ze-IP yomthombo kunye nendawo oya kuyo kunye namazibuko. Zine iindlela onokukhetha kuzo ukuchaza umthetho: vumela, khanyela, khanyela, kunye nomda. Ukwala kuya kubuyisela umyalezo «I-ICMP: indawo ekuyiwa kuyo ayinakufikeleleka»Kumfaki sicelo. Umda ukuvumela ukuba unciphise inani lemizamo yonxibelelwano engaphumelelanga. Oku kukukhusela ekuhlaselweni ngamandla. Nje ukuba umthetho wongezwe, uya kuvela kwiwindow ephezulu ye Wowu.

Kwaye ke uya kuyilungisa kwaye uyilungiselele i-firewall okanye i-firewall. Isixhobo esibaluleke kakhulu osikhumbulayo sinokujikela kuwe, kuba ukuba awukhumbuli i-firewall okanye amazibuko avaliweyo okanye avuliweyo, uninzi lweengxaki lunokuvela. Uya kundixelela.

    Kudala ndizama ukuyisebenzisa iinyanga zilandela zonke izikhombisi abazikhankanyileyo, hayi kweli nqaku kuphela kodwa nakwabanye abaninzi kumnatha, kwaye ndicinga ukuba ulwabiwo kuphela olusebenzayo ngoku luseOpenSUSE, ezinye kwezinye; Ithatha ixesha elide ukuyenza kwaye uyiqwalasele kunokuba iyeke ukusebenza.

    Ndifuna ukumisela i-gufw ukukhanyela konke ukungena kunye nazo zonke izithuthi eziphumayo ngaphandle kwe-firefox, thunderbird, filezilla, umphathi wohlaziyo, ubuntu software centery jdownloader. ngelishwa uluhlu lwemithetho ezenzekelayo kwicandelo elilula lufutshane kakhulu kwaye alubandakanyi nayiphi na kwezi nkqubo. Ngaba ungabhala inqaku elichaza ukuba ungafumanisa ukuba zeziphi izibuko ezisetyenziswayo zezi nkqubo kunye nendlela yokufumana?

      Molo 🙂 Sebenzisa iNgxelo yokuMamela ukuze wazi ukuba zeziphi iipropathi ezisebenzisa inkqubo nganye 😉 Inikwe amandla kwimenyu yokuHlela / yokuKhetha.
