Ukufaka iSsh-Server in Ubuntu

Iphrothokholi ye-SHS isetshenziselwa ukuqinisekisa ukuxhumana okuphephile kwikhompyutha, evumela ukulawulwa okukude kungabi nge-Shell System kuphela, kodwa futhi nesiteshi esibethelwe. Kwesinye isikhathi abasebenzisi bohlelo olusebenzayo lwe-Ubuntu banesidingo sokuletha iseva ye-SSH kwi-PC yayo ukuze basebenzise noma yiziphi izinhloso. Ngakho-ke, sinikeza ukujwayelana nale nqubo, njengoba ufunde hhayi inqubo yokulanda kuphela, kodwa futhi nokuhlelwa kwamapharamitha amakhulu.

Faka iSsh-Server in Ubuntu

Izakhi ze-SHS ziyatholakala ngokulanda nge-Storage Esemthethweni, ngakho-ke sizocubungula le ndlela, kuzinza kakhulu futhi zithembekile, futhi futhi akubangeli ubunzima kubasebenzisi be-novice. Sishaye yonke inqubo nezinyathelo zokuba lula ukuzulazulela imiyalo. Ake siqale kusukela ekuqaleni.

Isinyathelo 1: Landa bese ufaka i-SHS-Server

Nweba umsebenzi uzoba nge- "terminal" usebenzisa isethi eyinhloko yemiyalo. Awudingi ulwazi olungeziwe noma amakhono, uzothola incazelo eningiliziwe yesenzo ngasinye nayo yonke imiyalo edingekayo.

1. Gijimisa ikhonsoli ngemenyu noma ukuncipha inhlanganisela ye-Ctrl + Alt + T.



2. Ngokushesha qala ukulanda amafayela weseva kusuka kwi-repository esemthethweni. Ukuze wenze lokhu, uzodinga ukufaka i-Sudo Apt Faka i-OpenSsh-Server, bese ucindezela inkinobho ethi Enter.



3. Njengoba sisebenzisa ikhonsoli yeSUD (enze isenzo egameni leSuperuser), uzodinga ukufaka iphasiwedi kusuka ku-akhawunti yakho. Qaphela ukuthi izinhlamvu aziboniswanga lapho zingena.



4. Uzokwaziswa ngokulanda inani elithile lezingobo zomlando, qinisekisa isenzo ngokukhetha i-D. Ongakukhetha



5. Ngokuzenzakalelayo, iklayenti lifakwe kanye neseva, kepha ngeke libe yinhle kakhulu ukwenza ukuthi kwenzeke, ukuzama ukuyifaka futhi ukusebenzisa i-Sudo Apt-Client.

Iseva ye-SSH izotholakala ukuthi ihlanganyele nayo ngokushesha ngemuva kokungeza ngempumelelo wonke amafayela ohlelweni olusebenzayo, kepha kufanele kulungiselelwe ukuhlinzeka ngokusebenza okulungile. Sikucebisa ukuthi ujwayelane nezinyathelo ezilandelayo.

Isinyathelo 2: Ukuqinisekiswa kweseva

Okokuqala, ake uqiniseke ukuthi amapharamitha ajwayelekile asetshenziswe kahle, futhi iseva ye-SHSH iphendula amaqembu amakhulu futhi ibanze kahle, ngakho-ke uyakudinga:

1. Gijimisa ikhonsoli bese ubhalisa lapho i-Sudo SystemctL inika amandla i-SSHD ukwengeza iseva ku-Ubuntu Autoload, uma kungenzeki ngokuzenzakalelayo ngemuva kokufakwa.



2. Uma ungadingi ukuqala ithuluzi kanye ne-OS, yisule kusuka ku-Autorun ngokufaka iSusto System Chable SHSHD.



3. Manje hlola ukuthi ikhompyutha yendawo ixhunyiwe kanjani. Faka isicelo somyalo we-SSH Localhost (Localhost - Ikheli le-PC yakho yendawo).



4. Qinisekisa ukuqhubeka kokuxhumeka ngokukhetha inketho ye-YES.



5. Uma kwenzeka ulande ngempumelelo, uzothola cishe imininingwane enjalo njengoba ungabona ku-skrini elandelayo. Udinga ukubheka nokuxhuma kwikheli le-0.0.0.0, elisebenza njengenethiwekhi ekhethiwe ip ngokuzenzakalelayo kwamanye amadivayisi. Ukuze wenze lokhu, faka umyalo ofanele bese uqhafaza ku-ENTER.



6. Ukuxhumana okusha okusha kufanele kuqinisekiswe.

Njengoba ubona, umyalo we-SHS usetshenziselwa ukuxhuma kunoma iyiphi ikhompyutha. Uma unesidingo sokuxhuma nenye ifoni, umane usebenzise i-terminal bese ufaka umyalo ngefomethi ye-SSH @ ip_adress.

Isinyathelo 3: Ukuhlela Ifayela Lokucushwa

Zonke izilungiselelo ezengeziwe ze-SSH Protocol zenziwa ngefayela lokucushwa elikhethekile ngokushintsha imigqa namagugu. Ngeke sigxile kuwo wonke amaphuzu, ngaphezu kwalokho, iningi lazo lingumuntu ngamunye kumsebenzisi ngamunye, sizokhombisa kuphela ngezenzo eziphambili.

1. Izogcina isipele sokuqala kwefayela lokucushwa ukuze uma uxhumana nalo noma ubuyisela isimo se-SSH sokuqala. Faka i-Sudo CP / ETC / SSH / SSHD_CONFIG / SSH / Sshd_Config / SSH / Sshd_Config / SSH / Sshd_Config / Ssh / Sshd_Config / SHSH / SHshd_Config.



2. Ngemuva kwalokho isekhondi: sudo Chmod A-W /TC/SSSH/SSHD_CONIG.ICONIGINE.



3. Ukuqala ifayela lezilungiselelo kwenziwa nge-Sudo Vi / njll / SSH / SSHD_CONIG. Masinyane ngemuva kokungena, kuzokwethulwa futhi uzobona okuqukethwe kwawo, njengoba kukhonjisiwe esikrinini esingezansi.



4. Lapha ungashintsha imbobo esetshenzisiwe, okungcono njalo ukuyenza ukuze uqinisekise ukuphepha kokuxhumeka, khona-ke ukungena ngemvume kungavalwa egameni le-superter (i-pubrootlogin) kanye nokwenza kusebenze kukhiye (i-punkeyelekauthenting). Lapho usuqedile ukuhlela, cindezela inkinobho: (Shift +; kwisakhiwo seLatin) bese wengeza uhlamvu w ukuze ugcine ushintsho.



5. Ukukhishwa okuvela efayelwe kukwenziwa ngendlela efanayo, kuphela esikhundleni salokho kusebenzisa i-Q.



6. Ungakhohlwa ukuqala kabusha iseva ngokufaka iSudo Systemctl restart ssh.



7. Ngemuva kokushintsha imbobo esebenzayo, kufanele ilungiswe kwiklayenti. Lokhu kwenziwa ngokucacisa i-SSH -P 2100 yasendaweni yendawo, lapho i-2100 iyinombolo yetheku elinqunyelwe.



8. Uma ulungiselelwe yi-firewall, kuyadingeka futhi ukuthi ungene esikhundleni: sudo UFW Vumela i-2100.



9. Uzothola isaziso sokuthi yonke imithetho ivuselelwe.

Unelungelo lokuzijwayeza namanye amapharamitha ngokufunda imibhalo esemthethweni. Kunezeluleko zokushintsha zonke izinto ukusiza ukunquma ukuthi yiziphi izindinganiso okufanele ukhethe.

Isinyathelo 4: Ukungeza okhiye

Lapho ungeza izinkinobho, i-SHSH ivula ukugunyazwa phakathi kwamadivayisi amabili ngaphandle kwesidingo sokufaka iphasiwedi. Inqubo yokuhlonza yakhiwa kabusha ngaphansi kwe-algorithm yokufunda ukuze uthole imfihlo kanye nokhiye ovulekile.

1. Vula ikhonsoli bese udala ukhiye weklayenti omusha ngokufaka i-SHSH-keygen -t DSA, bese unikeza igama lefayela bese ucacisa iphasiwedi yokufinyelela uqobo.



2. Ngemuva kwalokho, ukhiye womphakathi uzosindiswa bese kuthi isithombe esiyimfihlo. Esikrinini uzobona ukubukeka kwakhe.



3. Ihlala kuphela ukukopisha ifayela elakhiwe kwikhompyutha yesibili ukukhubaza ukuxhumana ngephasiwedi. Sebenzisa umyalo we-SHS-Copy-ID kwigama lomsebenzisi @ remotehost, lapho igama lomsebenzisi @ tusmotehost yigama lekhompyutha eyihlane nekheli layo le-IP.

Ihlala kuphela ukuqala kabusha iseva bese uhlola ukunemba kwayo kokusebenza ngokhiye ovulekile noyimfihlo.

Kulokhu, inqubo yokufaka yeseva ye-SSH nesilungiselelo sayo esiyisisekelo sekuqediwe. Uma ufaka yonke imiyalo kahle, akufanele kube namaphutha lapho wenza umsebenzi. Uma kwenzeka noma yiziphi izinkinga ngokuxhuma ngemuva kokusetha, zama ukususa i-SSH kusuka ku-autoloadiading ukuxazulula inkinga (Funda ngakho kusinyathelo 2).
