Ulubalekisa njani unxibelelwano lwe-SSH kwi-GNU / Linux

Las Unxibelelwano lweSSH yenye yazo izixhobo ezisetyenziswa kakhulu yiSysAdminOku ikakhulu kungenxa yokuguquguquka kwayo kunye nokhetho olufanelekileyo kakhulu lokhuseleko, kodwa phantse kuzo zonke iindlela zonxibelelwano kukho iindlela ezininzi zokuyisebenzisa kwaye ezinye zithetha ukuba isantya esifumanekayo ayisoloko ingcono. Kwezo meko, ngelishwa, kuyakufuneka sibhenele kwezinye iindlela zohlengahlengiso ezisivumela ukuba sifumane umgangatho woqhagamshelo ohloniphekileyo noqinisekileyo, yiyo loo nto sifuna ukubonisa Iindlela ezi-3 zokukhawulezisa unxibelelwano lwe-SSH kwi-GNU / Linux.

Ngokusisiseko, sifuna ukuthetha malunga iinketho zoqwalaselo oko kuyasivumela ukuba soyise imiqobo enje ngonxibelelwano olubi, okanye inyani yokuba senza unxibelelwano oluninzi ngaxeshanye kwiseva enye, kwezinye iimeko nokufikelela kwizixhobo zemizobo X Ukuhambisa phambili, ezinokwenza isantya esifunekayo siphezulu.

Enye yezinto zokuqala esinokuzenza zezi Nyanzela uqhagamshelo lwe-SSH ngaphezulu kwe-IPv4Le protocol ikwamkela unxibelelwano kwi-IPv6 entsha, ethi ngamanye amaxesha igqibe iyimfuneko kodwa okwangoku ayisiyiyo, kwaye inyani yokusebenzisa inkxaso kuzo zombini kuthetha ukuba ngamanye amaxesha unxibelelwano kunokuba yinto ethe chu. Kodwa sinokunxibelelana nakweyiphi na iseva sisebenzisa i-SSH kuphela nge-IPv4 sisebenzisa ipharamitha "-4" ngoku Landelayo:

# ssh -4 umsebenzisi@remoteserver.com

Enye indlela yokufezekisa oku kukutshintsha ifayile yoqwalaselo / njl / ssh / ssh_config, kufuneka sijonge phi ngomgca "Idilesi yoSapho" kwaye umshiye nesibindi "Inet", yiyo loo nto ichaza ukuba siza kuqhagamshela usebenzisa i-IPv4.

Olunye uqwalaselo oluza kusivumela ukuba siphucule isantya yile khubaza ukuKhangelwa kwe-DNS Kwikhompyuter ekude, kwaye konke oku kukukhangela i-IP yekhompyuter kwaye kuyo ukufumana igama lenginginya yinto efuna izixhobo kwaye inceda ukwenza izinto kancinci kancinci, ekufuneka siye kuzo kuqwalaselo lwefayile Iseva ye-SSH, (/ njl / ssh / sshd_config) kwaye ushiye ukhetho lwe "SebenzisaDNS" ngenkalipho "hayi". Nathi sinako ukwenjenjalo Nyanzela ukusetyenziswa kwakhona konxibelelwano lweSSHNgamanye amagama, xa kusekelwa unxibelelwano olutsha, kuya kwenziwa ilinge lokuphinda usebenzise esele imiselwe, into ngokungathandabuzekiyo inokukhawuleza kakhulu kunokwenza entsha.

Ngenxa yoku, siya kwifayile / njl / ssh / ssh_config kwaye ungeze le mizila elandelayo:

Ulawulo lweMasters auto
Ulawulo lwendlela - /. I-Ssh / iziseko /% r% h-% p
Umlawuli wePersist 600

Umgca wokugqibela (uLawuloPersist) uya kuxela inkonzo ye-SSH ukuba igcine uqhagamshelo luvulekile -kodwa ngasemva- kwimizuzwana engama-600 emva kokuba ivaliwe, ukuyisebenzisa kwakhona kwimeko yokufumana isicelo soqhagamshelo esitsha. Ukuba songeza umgca "Igama lomncedisi wegama" singabonisa ukuba oku kuqwalaselwa kusetyenziselwa kuphela Unxibelelwano lweSSH kwikhompyuter ethile, esiyibuyisela ngegama leservern negama elifanelekileyo.

Ngolu hlengahlengiso lulula sinokufikelela kuphuculo oluthile kwi Isantya sonxibelelwano lweSSH kwaye nakwixesha apho ezi zithatha ukuzimisela, into engazukuqondakala ukuba sinobubanzi bebhendi kwaye sisebenza kuthungelwano lwasekhaya, kodwa ngokuqinisekileyo siya kuyivuyela into yokuba sidibanisa neeseva ezininzi ezikude.
