Abona bathengi baziwayo be-SSH beLinux [Mahala kwaye bahlawulwe]

Ngokufutshane: I-SSH yiprothokholi ethandwayo ekude yokwenza uqhagamshelo olukhuselekileyo olukude. Kwesi sikhokelo, siphonononga abona baxhasi baziwayo be-SSH beLinux.

I-SSH (i-Shell eKhuselekileyo) irenki njengenye yezona ndlela zidumileyo nezithembekileyo ezikude zokunxibelelana nezixhobo ezikude ezifana neeseva kunye nezixhobo zenethiwekhi, kubandakanya iirotha kunye nokutshintsha.

I-encrypts traffic ethunyelwe ngasemva naphambili kwaye iqinisekisa ukhuseleko lwedatha ngexesha leseshini ekude. I-SSH yiprothokholi yoqhagamshelo olukude lweengcali ze-IT, iinkqubo kuny

Uyisebenzisa njani iSSH ProxyJump kunye neSSH ProxyCommand kwiLinux

Ngokufutshane: Kwesi sikhokelo, sibonisa indlela yokusebenzisa i-SSH ProxyJump kunye nemiyalelo ye-SSH ProxyCommand xa uqhagamshela kwiseva yokutsiba.

Kwisikhokelo sethu sangaphambili malunga nendlela yokuseta i-SSH Jump Server, sigubungele ingqikelelo ye-Bastion Host. Umamkeli we-Bastion okanye iSeva ye-Jump sisixhobo somlamli apho umxhasi we-SSH aqhagamsheleka kuso kuqala ngaphambi kokufikelela kwinkqubo yeLinux ekujoliswe kuyo. Iseva ye-SSH Jump isebenza njengesango kwizixhobo zakho ze-IT, ngaloo ndlela inciphisa umphezulu wohlaselo.

Igobolondo kwiBhokisi-Fikelela kwiSitenari ye-Linux SSH ngeSikhangeli seWebhu

Iqokobhe eliseBhokisini (elibizwa ngokuba yi-shellinabox) sisilingisi se-terminal esekwe kwiwebhu esenziwe nguMarkus Gutschke. Inomncedisi wewebhu owakhelwe-ngaphakathi osebenza njengomthengi we-SSH esekwe kwiwebhu kwizibuko elikhankanyiweyo kwaye ikwenza ukuba ube kwi-emulator ye-terminal yewebhu ukufikelela kunye nokulawula i-Linux Server SSH Shell yakho ukude usebenzisa nayiphi na i-AJAX/JavaScript kunye CSS- yenziwe yasebenza izikhangeli ngaphandle kwesidingo sazo naziphi na iiplagi zebrawuza ezongezelelweyo ezifana neFireSSH.

Kule tutorial, ndichaza indlela yokufaka iShell

Ulisusa njani iPassphrase kwiSatifikethi se-SSL kunye neSitshixo se-SSH

Mafutshane: Ingaba ulenzile isitshixo sesatifikethi okanye isitshixo sabucala kunye nebinzana lokugqithisa kwaye unqwenela ukulisusa? Kwesi sikhokelo, siya kubonisa indlela yokususa igama lokugqithisa usebenzisa i-openssl isixhobo somgca womyalelo kunye neqhosha labucala le-ssh.

Ibinzana lokugqithisa lulandelelwano lwamagama asetyenziselwa ukukhusela nokulawula ukufikelela kwiqhosha labucala. Liqhosha okanye imfihlo esetyenziselwa ukuguqulela ngokuntsonkothileyo ifayile equlathe elona qhosha loguqulelo oluntsonkothileyo.

Ukusebenzisa isitshixo sabucala soguqulelo olunts

Olona setyenziso luqhelekileyo lomyalelo we-SSH kunye noqwalaselo kwiLinux

Mfutshane: Kwesi sikhokelo, siza kuxubusha iimeko zokusetyenziswa okuqhelekileyo kwe-SSH. Siza kuxubusha kwakhona ulungelelwaniso oluqhelekileyo lwe-SSH olunokusetyenziswa kubomi bemihla ngemihla ukunyusa imveliso yakho.

I-Shell ekhuselekileyo (i-SSH) yinkqubo yothungelwano eyamkelwe ngokubanzi, evumela ukuba sidibane neenginginya ezikude ngendlela ekhuselekileyo. Inika ukhuseleko ngokufihla lonke unxibelelwano phakathi kwabo.

Uwusebenzisa njani Umyalelo weSSH kwiLinux

Kweli candelo, siza kuxoxa ngezinye iimeko zokusetyenziswa ezidumileyo zeSSH protocol.

IiNdlela ezi-5 eziLungileyo zokuThintela i-SSH Brute-Force Login Attacks

Iiseva eziqhuba i-SSH zidla ngokuba ziithagethi ezithambileyo zohlaselo lwamandla akhohlakeleyo. Abaduni bahlala beza nezixhobo zesoftware entsha kunye ne-bots zokuzenzela uhlaselo lwe-brute-force olunyusa ngakumbi umngcipheko wokungena.

Kwesi sikhokelo, siphonononga ezinye zeengcebiso onokuthi uzisebenzise ukukhusela iiseva zakho ze-SSH kuhlaselo olukhohlakeleyo lwezinto eziphuma kwi-Debian.

Khubaza uQinisekiso lwegama lokugqithisa le-SSH kwaye uvule uQinisekiso lweSitshixo se-SSH

Indlela yoqinisekiso engagqibekanga ye-SSH ligama lomsebenzisi/igama lokugqitha. Kodwa nje

Uwubonisa njani umyalezo wesilumkiso kwi-SSH Abasebenzisi abangagunyaziswanga

Izilumkiso zesibhengezo se-SSH zibalulekile xa iinkampani okanye imibutho ifuna ukubonisa umyalezo ongqongqo wesilumkiso ukutyhafisa abasebenzisi abangagunyaziswanga ekufikeleleni kwiseva yeLinux.

Le miyalezo yesilumkiso yesibhengezo se-SSH iboniswa kanye phambi kokukhawuleza kwegama lokugqitha le-SSH ukuze abasebenzisi abangagunyaziswanga abazakufumana ukufikelela baziswe ngesiphumo sokwenza oko. Ngokwesiqhelo, ezi zilumkiso ziziphumo ezisemthethweni apho abasebenzisi abangagunyaziswanga banokuchaphazeleka ukuba bagqibe kwelokuba baqhubele phambili nokufikelela kwiseva.

Uyiseta njani iSeva yeNgxoxo yaBucala ngeYtalk ngaphezulu kweSSH

I-Ytalk yingxoxo yasimahla yabasebenzisi abaninzi esebenza ngokufanayo nenkqubo yentetho ye-UNIX. Inzuzo ephambili ye-ytalk kukuba ivumela uxhulumaniso oluninzi kwaye lukwazi ukunxibelelana naliphi na inani elingenasizathu labasebenzisi ngaxeshanye.

Kweli nqaku, siya kuchaza indlela yokufaka kunye nokuseta iseva yengxoxo yangasese, efihliweyo kunye neqinisekisiweyo kunye neYtalk phezu kwe-SSH yokufikelela okukhuselekileyo, okungaphantsi kwephasiwedi kwiseva yengxoxo, kumthathi-nxaxheba ngamnye.

Useta njani uQinisekiso lweeFactor ezimbini ze-SSH kwiFedora

Yonke imihla kubonakala ngathi kukho ukophulwa kokhuseleko okuninzi okuxeliweyo apho idatha yethu isengozini. Ngaphandle kwenyani yokuba i-SSH yindlela ekhuselekileyo yokuseka udibaniso ukude kwindlela ye Linux, kodwa nangoko, umsebenzisi ongaziwayo angafumana ufikelelo kumatshini wakho we Linux ukuba bayeba izitshixo zakho ze-SSH, nokuba uvala amagama agqithisiweyo okanye uvumela kuphela imidibaniso yeSSH ngaphezulu. izitshixo zikawonke-wonke kunye nezabucala.

Kweli nqaku, siza kuchaza indlela yokuseta ukuqinisekiswa kwezinto ezimbini (2FA) ye-SSH kwi-Fedora Linux ukuhanjiswa usebenz

Tmate-Yabelana ngokukhuselekileyo ngeSeshini yeSitena yeSSH kunye nabasebenzisi beLinux

I-tmate yiclone ye-tmux (i-terminal multiplexer) enikezela ngokhuseleko, ngokukhawuleza kwaye kulula ukuyisebenzisa isisombululo sokwabelana nge-terminal phezu koqhagamshelwano lwe-SSH. Yakhiwe phezu kwe-tmux; ungaqhuba zombini i-terminal emulators kwindlela enye. Unokusebenzisa iiseva ezisemthethweni kwi-tmate.io okanye ubambe eyakho iseva ye-tmate.

Lo mfanekiso ulandelayo ubonisa umzobo woyilo olula kunye namacandelo ahlukeneyo e-tmate (efunyenwe kwiwebhusayithi yeprojekthi).
