I-SSH yokufunda: Amafayela Wokufaka kanye Nokumisa

Kokuthunyelwe kwakamuva mayelana I-SSH ne-OpenSSH, sikhuluma ngethiyori ebaluleke kakhulu okufanele yaziwe ngalokhu ubuchwepheshe kanye nohlelo. Khonamanjalo, kulokhu okuthunyelwe namuhla sizongena kukho ukufakwa, nezabo amafayela we ukusetha okuyisisekelo, ukuze uqhubeke « ukufunda i-SSH».

Bese, ezitolimende ezizayo, sizobhekana nokunye imikhuba emihle (izincomo) yamanje, lapho wenza izilungiselelo eziyisisekelo nezithuthukile. Futhi, mayelana nokusetshenziswa kwezinye imiyalo elula futhi eyinkimbinkimbi ngokusebenzisa ubuchwepheshe obushiwo. Ukusebenzisa lokhu, abaningi izibonelo ezingokoqobo nezingokoqobo.

Futhi njengenjwayelo, ngaphambi kokungena ngokugcwele esihlokweni sanamuhla ohlelweni olwaziwayo I-OpenSSH ku-GNU/Linux, ngakho qhubeka « ukufunda i-SSH», sizoshiyela labo abathakazelayo izixhumanisi ezilandelayo zezincwadi ezihlobene zangaphambilini. Ngendlela yokuthi bangazihlola kalula, uma kunesidingo, ngemva kokuqeda ukufunda le ncwadi:

“I-SSH imele i-Secure Shell iyiphrothokholi yokufinyelela okukude okuphephile nezinye izinsiza zenethiwekhi ezivikelekile ngenethiwekhi engavikelekile. Ngokuqondene nobuchwepheshe be-SSH, i-OpenSSH idume kakhulu futhi isetshenziswa. I-SSH ingena esikhundleni sezinsizakalo ezingabhaliwe njenge-Telnet, i-RLogin, ne-RSH futhi yengeza ezinye izici eziningi. I-Debian Wiki

I-SSH yokufunda: Iphrothokholi yokufinyelela okukude okuvikelekile

Ukufunda ngokufaka i-SSH

Kulezo amakhompyutha (abasingathi) lokho kuzosebenza njenge Abasunguli bokuxhumeka kwe-SSH kufanele uqalise ukufakwa kwephakheji kumakhompiyutha weklayenti, okuvame ukubizwa ngokuthi iklayenti elivula. Ukwenza lokhu, ngokwesibonelo, kuma-Operating Systems amahhala futhi avulekile njenge I-Debian GNU / Linux, umyalo olandelayo kufanele wenziwe kusukela kutheminali eneseshini yezimpande:

«apt install openssh-client»

Ngaleso sikhathi, kubabungazi abazosebenza njengabamukeli boxhumo lwe-SSH, ukufakwa kwephakheji yamakhompyutha eseva kufanele kwenziwe. okuvame ukubizwa ngokuthi i-openssh-server futhi ifakwe ngokukhipha umyalo olandelayo ovela ku-terminal ene-root session:

«apt-get install openssh-server»

Uma isifakiwe, ngokuzenzakalelayo, kokubili kumakhompuyutha eklayenti neseva, ukuxhumana noma ukusebenza kokufinyelela okukude kungenziwa phakathi kwakho. Isibonelo, ukuze ufinyelele umsingathi obizwa Ikhompyutha_ekude ne $remote_user Kungenxa yomyalelo olandelayo ovela kutheminali eneseshini yezimpande:

«ssh $usuario_remoto@$equipo_remoto»

Futhi siyaqeda, ukubhala ukhiye womsebenzisi we- $remote_user.

Nakuba, uma igama lomsebenzisi emshinini wasendaweni nowakude lifana, singeqa ingxenye ye $remote_user@ futhi simane sikhiphe umyalo olandelayo ovela ku-terminal ene-root session:

«ssh $equipo_remoto»

Ukucushwa okuyisisekelo kwe-OpenSSH

Ukuze usebenzise imiyalo eyinkimbinkimbi usebenzisa izinketho ezitholakalayo zemiyalo nokusebenzisa izilungiselelo ezithuthukile, khumbula lokho I-OpenSSH inamafayela okumisa angu-2. omunye wabiza ssh_config yokucushwa kwe iphakethe leklayenti nolunye ucingo sshd_config for the iphakethe leseva, zombili zitholakala endleleni elandelayo noma uhla lwemibhalo: /etc/ssh.

Lezi ongakhetha kukho umyalo ingajula nge imanuwali yokusetshenziswa komyalo we-SSH ngaphakathi kwemibhalo esemthethweni isilungele. Khonamanjalo, ngento efanayo mayelana nemingcele yokumisa yeklayenti nephakheji leseva, izixhumanisi ezilandelayo zingasetshenziswa: ssh_config y sshd_config.

Kuze kube manje, sesifinyelele ithiyori ebaluleke kakhulu okufanele uyazi futhi ube nayo mayelana ne-SSH ukuyifaka futhi uqale ukufunda indlela yokuyibamba kahle. Nokho, kulezi zitolimende (izingxenye) ezilandelayo kulesi sihloko, sizocubungula lokho osekuxoxiwe ngakho.

Ulwazi oluningi

Futhi njengasesitolimendeni sokuqala, ngoba wandise lolu lwazi Sincoma ukuthi uqhubeke uhlole okulandelayo okuqukethwe okusemthethweni futhi enokwethenjelwa ku-inthanethi mayelana I-SSH ne-OpenSSH:

1. I-Debian Wiki
2. Imanuwali Yomlawuli We-Debian: Ukungena Okukude / I-SSH
3. I-Debian Security Handbook: Isahluko 5. Ukuvikela izinsiza ezisebenza kusistimu yakho

Isifingqo

Ngamafuphi, ukufaka, ukulungisa, nokusebenzisa ubuchwepheshe ngempumelelo nangempumelelo SSH nge-OpenSSH, kudinga izinyathelo ezilula, kodwa kufanele zihambisane nokufundwa okuningi, ukuqonda kanye nekhono lakho imiqondo, imingcele kanye nobuchwepheshe. Eziningi zazo, namuhla sikhulume kafushane lapha, ukufeza le nhloso. Okusho ukuthi, ukuqashwa okuthembekile nokuphephile kwe- Ubuchwepheshe be-SSH njengoba uxhumano nendlela yokungena kwabanye amaqembu akude.

Siyethemba ukuthi lolu shicilelo luwusizo olukhulu kubo bonke «Comunidad de Software Libre, Código Abierto y GNU/Linux». Futhi ungakhohlwa ukuphawula ngakho ngezansi, futhi wabelane ngakho nabanye kumawebhusayithi ayizintandokazi zakho, iziteshi, amaqembu noma imiphakathi yezokuxhumana nabantu noma izinhlelo zemiyalezo. Ekugcineni, vakashela ikhasi lethu lasekhaya ku «DesdeLinux» ukuhlola ezinye izindaba, bese ujoyina isiteshi sethu esisemthethweni se- I-Telegram ye DesdeLinux, ENtshonalanga iqembu ukuze uthole ulwazi olwengeziwe ngale ndaba.
