Igikoresho kigenzura kugera kuri port za TCP

Icyo iki kizamini kikubwira

Koresha iki kizamini kugira ngo ugenzure niba serivisi ishobora kugerwaho binyuze kuri aderesi rusange, router cyangwa aho VPN isohokera. Port ifunguye isobanura ko ihuriro rya TCP ryagenze neza muri iyi nzira. Ntibisobanura ko serivisi ifite intege nke, yagenwe neza cyangwa ishobora kugerwaho n’imiyoboro yose.

Uko wakora ikizamini

1. Hitamo aderesi rusange wemewe kugerageza n’umubare muto wa port za TCP zireba serivisi ucunga.
2. Genzura ko serivisi itegerejwe ikora, hanyuma utangize ikizamini cy’ihuriro.
3. Soma uko buri port ihagaze ukwayo, harimo kwangwa, igihe cyarenze n’amakosa y’aho uri cyangwa y’inzira.

Uko gupima bikora

Seriveri yacu igerageza ihuriro rya TCP kuri buri port yatoranyijwe. Itangaza niba iryo huriro ryagenze neza, ryaranzwe, igihe cyarenze cyangwa ridashobora gusobanurwa.

Igipimo gitangirira kuri seriveri y’ikizamini, si kuri mushakisha yawe. Kugenzura aderesi igenewe bigabanya aderesi rusange zishobora kugeragezwa; nta makuru ya UDP cyangwa kwemeza umwirondoro kuri porogaramu bigeragezwa.

Gusobanukirwa ibisubizo byawe

Ifunguye

Aderesi igenewe yemeye ihuriro rya TCP rivuye kuri iyi seriveri. Porogaramu iri inyuma ya port ishobora gukenera kwemeza umwirondoro cyangwa kunanirwa ibizamini bya protocole yayo.

Ihuriro ryanze

Ihuriro ryanze ku buryo bweruye muri iyi nzira. Serivisi ifunze cyangwa urukuta rw’umutekano rwanga bishobora kubisobanura.

Nta gisubizo cyangwa ntibyamenyekanye

Igihe cyarenze gishobora guterwa no kuyungurura cyangwa inzira itagerwaho. Amakosa y’uburenganzira bw’aho uri, inzira cyangwa umuryango wa aderesi akomeza kutamenyekana aho kuyitirira aderesi igenewe.

Gereranya mbere na nyuma

1. Andika aderesi igenewe, umuryango wa aderesi, port n’uko serivisi ikora ihagaze.
2. Hindura itegeko rimwe ry’urukuta rw’umutekano cyangwa iryo kohereza amakuru, hanyuma wongere ugerageze kuri seriveri y’ikizamini imwe.
3. Gereranya uko buri kimwe gihagaze. Niba VPN ihinduye IP igenewe, andika iryo hinduka na ryo kuko uba ugerageza ahandi rusange.

Imbogamizi z’ikizamini

• Ibiyungurura amakuru asohoka by’umuyoboro wakira serivisi n’inzira ijya ku igenewe bigira ingaruka ku gisubizo.
• Kugerwaho n’amakuru yinjira biterwa n’aho ahurira rusange n’amabwiriza y’inzira no kohereza; uko ihuriro rya VPN rihagaze byonyine ntibishobora kubyemeza.

Icyo wahindura, niba bikenewe

Serivisi ikenewe irangwa

Genzura ko itegera kuri aderesi na port bitegerejwe, hanyuma usuzume amabwiriza y’urukuta rw’umutekano bireba wongere ugerageze.

Igihe cya serivisi ikenewe kirarenga

Genzura ihitamo rya aderesi rusange, kohereza amakuru kwa router n’imbogamizi zo hejuru mbere yo gufungura izindi port.
