Isikhathi se-SSH sifa ne-VPN: tmux noma umqhubi wemisebenzi?

Isibonisi sakho se-VPN siba luhlaza, umzila uyabuya, futhi iwindi le-SSH owalishiya livulekile alibuyiseli uphawu lomyalo futhi. Ukubuyisela umzila akubuyiseli ingxoxo ye-TCP eyayiwusebenzisa, ngakho konke okwakuthayiphiwe kulelo windi kulahlekile. Uma ukukhathazeka kwangempela kuyibhafa yomhleli noma ukufuduka okude, isixazululo ukumisa ukubopha lowo msebenzi kuxhumo olulodwa. I-tmux nomqhubi wemisebenzi baxazulula izingxenye ezahlukene zale nkinga.

I-VPN exhunyiwe kabusha ayiqhubeki nesokhethi

I-TCP ayinawo umqondo wokuqhubeka ngemva kokushintsha ikheli. Uxhumo lwe-SSH lubonakala ngeziphetho zombili, futhi lapho umhubhe wakhiwa kabusha, ikheli lendawo lingashintsha futhi isokhethi endala ifile. Iseva ikubona ekugcineni, kodwa i-terminal yakho ikubona ngokushesha.

I-keepalive yeklayenti ithola umlingani ofile ngokushesha. Ayibuyiseli isikhathi, futhi ayikwazi ukubuyisela umyalo owawususebenza. I-keepalive iyisitholi, hhayi ithuluzi lokubuyisela. Ayisho lutho mayelana nokuthi umyalo okude wasinda yini.

Beka umsebenzi kumphetheleli okude

Dala isikhathi kumphetheleli okude, hhayi kukhompyutha ephathekayo. Xhumana ngokwejwayelekile, qalisa i-tmux lapho, futhi usebenzise umhleli noma ukufuduka ngaphakathi kwayo. Hlukana ngesiqalo esimisiwe futhi isikhathi siqhubeka sisebenza ngenkathi uxhumo lwe-SSH lunyamalala. Ukuqalisa i-tmux endaweni kuvikela ishelu yakho ewundini elivaliwe, hhayi umyalo okude emhubheni ofile.

ssh [email protected]
tmux new-session -s office-work

Lapho i-VPN ibuya, vula uxhumo olusha lwe-SSH kumphetheleli ofanayo futhi uxhume kabusha ngegama. Into ehlala isikhathi eside isikhathi, hhayi uxhumo. Yinike igama ozokwazi ukulibona ngisho ngemva kweviki.

i-tmux nomqhubi wemisebenzi

I-tmux igcina inqubo yokuxhumana iphila ngenkathi umphetheleli evuliwe. Umqhubi wemisebenzi noma umphathi wezinsizakalo ugcina umsebenzi ongenakho ukuxhumana uphila, uqopha isimo sawo sokuphuma, futhi usinda lapho isikhathi se-SSH siphela ngokuphelele. Owokuqala ungowomsebenzi oyibukayo; owesibili ungowomsebenzi oyihlelayo futhi uyihlola kamuva.

Akukho kokubili okusinda ekuqalisweni kabusha ngaphandle uma umphetheleli ulungiselelwe ukuwubuyisela. Isikhathi se-tmux sifa nomshini, futhi umsebenzi wesikhashana ufa nokuqalisa ngaphandle uma wawubhalisiwe njengeyunithi. Khetha ngokwalokho umsebenzi okufanele ukweqe.

Zombili izindlela zidinga nelogi ongayifunda ngemva kokuxhuma kabusha. Ngaphandle kwayo uyazi ukuthi inqubo ikhona, kodwa hhayi ukuthi yenzani. Bhala indlela yelogi eceleni kwegama lesikhathi.

Nquma ngokwalokho okufanele kusinde

Nquma ngokwento embi kakhulu engenzeka uma umsebenzi uyeka phakathi nendawo. Isikhathi somhleli silahlekelwa amabhafa angagciniwe, okuyinto ecasulayo kodwa engabuyiseka. Ukufuduka okubhalisa uhhafu wezinguquko zako akunjalo, futhi lokho kusekela umqhubi onomphumela oqoshiwe. Uma umsebenzi uxhumana futhi mude, i-tmux nelogi ebhaliwe ngokuvamile kwanele.

systemd-run --user --unit=migrate-customers --collect ./migrate.sh

Noma yini oyikhethayo, hlola umphumela oqoshiwe ngaphambi kokuqalisa noma yini futhi. Umugqa wokugcina ongekho ukutshela ukuthi ikhompyutha ephathekayo yabona ini, hhayi ukuthi iseva yaqopha ini. Lowo mehluko uyisizathu sokugcina umsebenzi ngaphandle koxhumo kusukela ekuqaleni, futhi imodeli yokuhlukana nokuxhuma kabusha iyisimo sako esincane kunakho konke.
