PPTP: Lembani Pulogalamu ya Point Tunneling

PPTP (Point-to-Point Tunneling Protocol) ndi njira yogwiritsira ntchito pulogalamu yogwiritsira ntchito Virtual Private Networks (VPN) . Mapulogalamu atsopano a VPN monga OpenVPN , L2TP, ndi IPsec angapereke chithandizo chabwino cha chitetezo cha intaneti, koma PPTP imakhala yotchuka kwambiri pulogalamu yapamwamba makamaka pa makompyuta a Windows.

Momwe PPTP imagwirira ntchito

PPTP imagwiritsa ntchito makasitomala- mapangidwe a seva (zolemba zamakono zomwe zili mu intaneti RFC 2637) zomwe zimagwira pa Mzere 2 wa chitsanzo cha OSI. Othandizira a PPTP VPN akuphatikizidwa ndi osakhulupirika ku Microsoft Windows komanso amapezeka kwa Linux ndi Mac OS X.

PPTP imagwiritsidwa ntchito kwambiri ku VPN kutalika kwa intaneti pa intaneti. Pogwiritsa ntchito izi, ma tunnel a VPN amapangidwa kudzera mu ndondomeko izi:

1. Wogwiritsa ntchito amalengeza makasitomala a PPTP omwe amagwirizana nawo pa intaneti
2. PPTP imapanga mgwirizano wa TCP pakati pa chithandizo cha VPN ndi seva ya VPN. Pulogalamuyo imagwiritsa ntchito phukusi la TCP 1723 chifukwa chogwirizana ndi General Routing Encapsulation (GRE) kuti potsiriza kukhazikitsidwe ngalande.

PPTP imathandizanso kuyanjana kwa VPN kudutsa pa intaneti.

Pambuyo pokonza ngalande ya VPN, PPTP imathandizira mitundu iwiri ya chidziwitso:

• sungani mauthenga otsogolera komanso potsiriza kuletsa kugwirizana kwa VPN. Kulemba mauthenga kumadutsa pakati pa VPN kasitomala ndi seva.
• mapaketi a deta omwe amadutsa mumsewu, kupita kapena kuchokera kwa chithandizo cha VPN.

Kukhazikitsa PPTP VPN Connection pa Windows

Ogwiritsa ntchito Windows amapanga malumikizano atsopano a Internet VPN motere:

1. Tsegulani Network ndi Sharing Center kuchokera ku Windows Control Panel
2. Dinani "Pangani chiyanjano chatsopano kapena chiyanjano"
3. Muwindo watsopano lomwe likuwonekera, sankhani kusankha "Kugwiritsira ntchito kuntchito" ndipo dinani Zotsatira
4. Sankhani "Gwiritsani ntchito njira yanga ya intaneti (VPN)"
5. Lowetsani chidziwitso cha adiresi pa seva ya VPN, perekani izi kugwiritsira ntchito dzina lapafupi (pansi pano momwe kusungidwa kwagwirizanowu kusungidwa kuti mugwiritsire ntchito mtsogolo), kusintha zosankha zonse zomwe mungasankhe, ndipo dinani Pangani

Ogwiritsa ntchito kupeza mauthenga a adiresi ya PPTP VPN kuchokera kwa oyang'anira seva. Otsogolera amalonda ndi sukulu amapereka kwa ogwiritsa ntchito mwachindunji, pomwe mautumiki a pa Intaneti a VPN amasindikiza mauthenga pa intaneti (koma nthawi zambiri zimagwirizanitsa ndi makasitomala okha). Zingwe zojambulira zingakhale dzina la seva kapena adilesi ya IP .

Pambuyo pothandizirayi itakhazikitsidwa nthawi yoyamba, ogwiritsa ntchito pa Windows PCwo akhoza kugwirizananso potsatira posankha dzina lapafupi kuchokera pawowonjezera mauthenga a Windows.

Kwa ogwira ntchito pazinthu zamakampani: Microsoft Windows amapereka mapulogalamu othandizira otchedwa pptpsrv.exe ndi pptpclnt.exe thandizo limenelo kutsimikizira ngati kukhazikitsa PPTP wachinsinsi ndi kolondola.

Kugwiritsa ntchito PPTP pa Mapulogalamu a Pakhomo ndi VPN Passthrough

Pogwiritsa ntchito makonde a panyumba, kugwirizana kwa VPN kumapangidwira kuchokera kwa kasitomala kupita ku seva lakutali la intaneti pogwiritsa ntchito routi yapamwamba . Ena okalamba apanyumba sakugwirizana ndi PPTP ndipo samalola kuti magalimoto apambuyo apitirize kugwirizana kwa VPN. Maulendo ena amalola kugwirizana kwa PPTP VPN koma amangogwirizanitsa umodzi umodzi panthawi imodzi. Zofooka izi zimachokera ku momwe njira ya PPTP ndi GRE ikugwirira ntchito.

Otsatira atsopano a kunyumba amalengeza zinthu zomwe zimatchedwa VPN passthrough zomwe zimasonyeza kuthandizira kwa PPTP. Woyendetsa nyumba ayenera kukhala ndi phukusi la PPTP 1723 lotseguka (kulola kugwirizana kukhazikitsidwa) komanso kupita ku GRE protocol mtundu 47 (kutsegula deta kudutsa njira ya VPN), zosankha zokhazikitsira zomwe zasinthidwa pa maulendo ambiri lerolino. Fufuzani zolemba za router za zovuta zina za VPN popanda kuthandizira kwa chipangizochi.
