Ukubanda kwe-RDP ku-VPN: okokufaka kusasebenza, ngakho hlola ukuthutha

Lapho isithombe siyeka ukubuyekezwa kodwa igundane lisahamba phezu kwedesktop ekude, isiphetho esisobala ukuthi i-VPN iwile. Leso siphetho ngokuvamile asilungile. Uhlaka olubandayo olunokokufaka okusebenzayo lusho ukuthi isikhathi somsebenzi kanye nomsele wakho wokokufaka kuphila, okusunduza iphutha ngasohlangothini lokuthutha kwemifanekiso hhayi ekuhambiseni noma emininingwaneni yokungena. Ukubona okubili okusheshayo kuhlukanisa amaphutha amathathu abasebenzisi abawachaza ngegama elilodwa.

Okungakutsheli ukubanda

Idesktop ekude ithwala okokufaka kanye nokubuyekezwa kwesikrini nge-TCP 3389, futhi amaklayenti e-Windows amanje angangeza ukuthutha kwe-UDP engxenyeni yomsakazo esindayo kwezemifanekiso. Emhubheni ohlukanisa noma olahla amadathagram amakhulu, umsele othembekile uqhubeka uthwala ukucindezelwa kwezinkinobho ngenkathi umsele wemifanekiso umile. Umphumela iyinhlanganisela eyinqaba yesithombe esimile nekhibhodi ephendulayo. Lokhu kubuye kuchaze ukuthi kungani ukuxhuma kabusha ngezinye izikhathi kwelapha uphawu umzuzu bese kubuyisa.

Isikhathi somsebenzi esinqamuka bese sixhuma futhi liphutha elinye, futhi esingavulwa neze lingelesithathu. Ukuqamba uhlobo kuqala kukuvimbela ukuhlola isendlalelo esingalungile.

Hlukanisa amaphutha amathathu ngemiyalo emibili

Ukukhipha ukufinyeleleka kushibhile. Hlola imbobo ye-RDP kusukela kuklayenti, bese ufunda isimo sesikhathi somsebenzi kuhosti.

Test-NetConnection rdp-host.example.com -Port 3389
query user /server:rdp-host

Ukuhlolwa kwe-TCP okwehlulekile kusho ukuthi isikhathi somsebenzi asikaze sivulwe, ngakho kuthatha njengenkinga yocingo lomlilo, ububanzi noma isevisi hhayi njengokubanda. Ukuhlolwa okuphumelelayo nesikhathi somsebenzi esisebenzayo kuqinisekisa ukuthi umsele wokulawula ukhona, okuyikho kanye icala lesithombe esibandayo. Gijimisa umbuzo wehosti kusukela ku-akhawunti evunyelwe ukubona izikhathi zomsebenzi, ngoba iphutha lemvume libonakala njengohlu olungenalutho. Bhala i-ID yesikhathi somsebenzi kanye nesimo, ngoba isikhathi somsebenzi esinqanyuliwe esigcina i-ID yaso asifani nesisebenzayo.

Cisha ukuthutha kwe-UDP bese uqhathanisa

Uma kumile isibonisi kuphela, qhathanisa ukuthutha kwamaklayenti ngokushintsha okukodwa ngesikhathi. Iklayenti elakhelwe ngaphakathi neklayenti le-Store azihlanganyeli isitaki esifanayo, futhi inqubomgomo engezansi isusa i-UDP kuklayenti elakhelwe ngaphakathi.

reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client" /v fClientDisableUDP

Inani elingu-1 lisho ukuthi i-UDP isivele icishiwe kulelo klayenti, ngakho ukubanda okuphila ngemuva kwalesi silungiselelo akunankinga yendlela ye-UDP. Uma inani lingekho, nika amandla inqubomgomo, xhuma futhi, bese uphinda ngokunembile isenzo esasibanda ngaphambili. Hlola iklayenti le-Store njengesinyathelo esihlukile esikhundleni sokuhlanganisa izinto ezimbili ezishintshiwe, ngaphandle kwalokho ngeke wazi ukuthi iyiphi eyayibalulekile. Gcina inguqulo yeklayenti emibhalweni yakho, ngoba ukuziphatha kokuthutha kushintshile phakathi kwezinguqulo ze-Windows.

Lapho ihosti eyodwa ibanda kodwa ezinye zilungile

Ihosti eyodwa ehlulekayo kunethiwekhi engaphansi enempilo ngakolunye uhlangothi ikhomba kude nomhubhe. Hlola i-MTU yendlela kanye nesitaki sesibonisi esikude ngaphambi kokuthinta izilungiselelo ze-VPN.

ping -f -l 1472 rdp-host.example.com

Impendulo ifakazela ukuthi indlela ithwala iphakethe elisayizi egcwele ngaphandle kokuhlukaniswa kuleso sayizi, kuyilapho ukwehluleka ngendlela yokungahlukanisi kubonisa ukuthi i-MTU yomhubhe idinga ukunakwa. Uma ama-byte angu-1472 edlula futhi kubanda lelo hosti kuphela, bheka umshayeli wemifanekiso kanye nomthwalo waso esikhundleni senethiwekhi. Ukukopisha ifayela ngokushesha kumshini ofanayo kusho okuthile mayelana nokugeleza, hhayi ngomsele wemifanekiso we-RDP. Shintsha uguquko olulodwa ngesikhathi bese uphinda isenzo esifanayo esikrinini ukuze ukuqhathanisa kube nencazelo.

Uma isikhathi somsebenzi singavulwa neze, yima lapha, ngoba lokho ukufinyeleleka hhayi ukubanda. Ngaphandle kwalokho gcina isilungiselelo sokuthutha esashintsha uphawu bese usibhala nenguqulo yeklayenti.
