Ngalesi sikhathi sizobona i- ithiphu emfushane futhi elula lokho kuzosisiza sithuthuke ukuphepha yokuxhumana kwethu okukude ne- ssh. |
I-OpenSSH, okuyiphakheji enikezwe izinhlelo ze-GNU / Linux ukuphatha ukuxhumana kwe-SSH, inezinketho ezahlukahlukene. Kufundwa incwadi I-SSH Igobolondo Eliphephile namakhasi ebhukwana ngithole inketho -F, etshela iklayenti le-SSH ukuthi lisebenzise ifayela lokumisa elihlukile kunalelo elitholwe ngokuzenzakalela kumkhombandlela we / etc / ssh.
Silusebenzisa kanjani lolu khetho?
Ngendlela elandelayo:
ssh -F / path / to_your / configuration / file user @ ip / Host
Isibonelo, uma sinefayela lokumisa ngokwezifiso elibizwa nge-my_config kuDeskithophu, futhi sifuna ukuxhumana nomsebenzisi uCarlos kwikhompyutha nge-IP 192.168.1.258, lapho-ke sizosebenzisa umyalo ngale ndlela elandelayo:
ssh -F ~ / Desktop / my_config carlos@192.168.1.258
Kusiza kanjani ukuphepha kokuxhumeka?
Khumbula ukuthi umhlaseli ongaphakathi kwesistimu yethu uzozama ngokushesha ukuthola amalungelo okuphatha uma engenawo, ngakho-ke kungaba lula kakhulu kuye ukwenza i-ssh ukuxhuma kuyo yonke eminye imishini kunethiwekhi. Ukugwema lokhu, singalungiselela ifayili le / etc / ssh / ssh_config ngamanani angalungile, futhi lapho sifuna ukuxhuma nge-SSH sizosebenzisa ifayili lokumisa esizobe sililondoloze endaweni esazi kuphela (noma ngaphandle isitoreji), okusho ukuthi, besingaba nokuphepha ebumnyameni. Ngale ndlela umhlaseli angadideka ukuthola ukuthi akakwazi ukuxhuma esebenzisa i-SSH nokuthi uzama ukwenza ukuxhumana ngokuya ngalokho okushiwo kufayela lokumisa okuzenzakalelayo, ngakho-ke kuzoba nzima ngaye ukubona ukuthi kwenzakalani, futhi sizomxaka kakhulu.umsebenzi.
Lokhu, kanye nokushintsha imbobo yokulalela yeseva ye-SSH, ukukhubaza i-SSH1, ukucacisa ukuthi yibaphi abasebenzisi abangaxhuma kuseva, ukuvumela ngokusobala ukuthi yiliphi ikheli le-IP noma ububanzi be-IP obungaxhuma kuseva, kanye namanye amathiphu angatholakala ku- http://www.techtear.com/2007/04/08/trucos-y-consejos-para-asegurar-ssh-en-linux , kuzosivumela ukuthi sandise ukuphepha kokuxhumana kwethu kwe-SSH.
Konke okuchazwe ngenhla kungenziwa kulayini owodwa. Ngokunambitha kwami ​​kungaba yisicefe impela ukubhala umugqa omkhulu ngezinketho eziningi njalo lapho sizama ukungena ngemvume nge-SSH kwi-PC ekude, ngokwesibonelo okulandelayo kungaba yisampula yalokhu engikushoyo:
ssh -p 1056 -c blowfish -C -l carlos -q nami 192.168.1.258
-p Icacisa imbobo yokuxhuma kusikhungo esikude.
-c Icacisa ukuthi iseshini kufanele ibethelwe kanjani.
-C Ikhombisa ukuthi iseshini kufanele icindezelwe.
-l Ikhombisa umsebenzisi ongena ngemvume kuye kumphathi wesilawuli kude.
-q Ikhombisa ukuthi imiyalezo yokuxilonga iyacindezelwa.
-i Ikhombisa ifayili elizokhonjwa nge (key yangasese)
Kumele futhi sikhumbule ukuthi singasebenzisa umlando wesiginali ukugwema ukuthayipha wonke umyalo njalo lapho siwudinga, into umhlaseli angayisebenzisa futhi, ngakho-ke angiyikuyincoma, okungenani ekusetshenzisweni kwe Ukuxhumana kwe-SSH.
Yize inkinga yezokuphepha kungeyona yodwa inzuzo yalolu khetho, ngicabanga ezinye, njengokuthola ifayili lokumisa kuseva ngayinye esifuna ukuxhuma kuyo, ngakho-ke sizokugwema ukubhala izinketho ngaso sonke isikhathi lapho sifuna ukuxhumana i-SSH yeseva enokumiswa okuthile.
Sebenzisa inketho ye -F kungasiza kakhulu uma ngabe unamaseva amaningi anokumiswa okuhlukile. Ngaphandle kwalokho, zonke izilungiselelo kuzofanele zikhunjulwe, okungenakwenzeka. Isixazululo kungaba ukuthi kube nefayela lokumisa elilungiselelwe ngokuphelele ngokuya ngezidingo zeseva ngayinye, lisiza futhi liqinisekise ukufinyelela kulawo maseva.
Ungathola imiyalelo yokuthi ungahlela kanjani ifayela lokucushwa kweklayenti le-SSH kulesi sixhumanisi http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config .
Khumbula lokhu kungenye yezeluleko ezingamakhulu esingazithola ukuqinisekisa i-SSH, ngakho-ke uma ufuna ukuba nokuxhumana okuvikelekile okukude kufanele uhlanganise phakathi kwamathuba i-OpenSSH esinikeza wona.
Yilokho kuphela okwamanje, ngiyethemba lolu lwazi luzoba usizo kuwe bese ulinda okunye okuthunyelwe okuphathelene nokuphepha kwe-SSH ngesonto elizayo.
Ngithakazelela i unikele?
