Txij li cov nruab nrab GNU/Linux neeg siv Nws feem ntau yog ib tus neeg tshaj lij, paub zoo lossis tus neeg tshaj lij hauv kev ua haujlwm. computer science ntiaj teb, qhov no yuam kom koj siv thiab paub cov cuab yeej tshwj xeeb lossis thev naus laus zis. Ib qho piv txwv zoo ntawm qhov no yog tej thaj chaw deb txuas rau lwm lub computer los yog cov khoom siv, duab lossis los ntawm lub davhlau ya nyob twg. Piv txwv li, a nruab nrab linux neeg siv, SysAdmins lossis DevOps, feem ntau yog los ntawm lub network (tsev, kev lag luam lossis hauv huab), txuas mus rau lwm lub khoos phis tawj los ntawm ntau cov txheej txheem lossis cov thev naus laus zis muaj rau nws, xws li, RDP, Telnet, SSH, thiab ntau lwm tus.

thiab nyiam ntau Cov kws tshaj lij IT peb twb paub lawm, muaj ntau yam software rau qhov no. Txawm li cas los xij, thaum nws los txog GNU / Linux Kev Siv Tshuab Ua Haujlwm, tshwj xeeb tshaj yog hais txog Tus pabcuam, qhov yooj yim tshaj plaws thiab qhov tseem ceeb, yog kev paub txog cov cuab yeej hu ua OpenSecureShell (OpenSSH). Yog vim li cas, hnub no peb yuav pib nrog thawj ntu ntawm SSH.

Kev coj ua zoo nrog OpenSSH

Thiab raws li niaj zaus, ua ntej nkag mus rau hnub no lub ntsiab lus hais txog qhov program «Qhib Secure Plhaub » (OpenSSH), kom muab qhov dav dav ntawm nws, peb yuav tawm rau cov neeg nyiam cov kev txuas hauv qab no rau qee qhov kev tshaj tawm yav dhau los. Nyob rau hauv xws li ib txoj kev uas lawv tuaj yeem tshawb nrhiav tau yooj yim, yog tias tsim nyog, tom qab ua tiav nyeem cov ntawv tshaj tawm no:

"Qee tus neeg siv yuav xav tias qhov kev coj ua zoo tshaj yuav tsum tsuas yog siv rau cov servers, thiab qhov no tsis yog li ntawd. Ntau GNU / Linux kev faib tawm suav nrog OpenSSH los ntawm lub neej ntawd thiab muaj ob peb yam uas yuav tsum nco ntsoov". Kev coj ua zoo nrog OpenSSH

SSH yog dab tsi?

Lub npe ntawm cov "SSH" technology los ntawm acronym ntawm cov lus Askiv “Secure Plhaub”, uas txhais hauv Spanish txhais tau tias, "Secure Plhaub" o "Secure Order Txhais Lus". Txawm li cas los xij, kom paub meej ntxiv thiab ua tiav cov lus piav qhia thiab kev txhais lus, peb tuaj yeem hais cov kab lus hauv qab no:

"SSH sawv cev rau Secure Plhaub yog cov txheej txheem rau kev nkag mus rau tej thaj chaw deb thiab lwm yam kev pabcuam kev ruaj ntseg hauv lub network tsis ruaj ntseg. Raws li rau SSH technologies, OpenSSH yog qhov nrov tshaj plaws thiab siv. SSH hloov cov kev pabcuam uas tsis tau sau npe zoo li Telnet, RLogin, thiab RSH thiab ntxiv ntau yam ntxiv. " Debian Wiki

"SSH raws tu qauv tau tsim nrog kev ruaj ntseg thiab kev ntseeg siab hauv siab. Kev sib txuas siv SSH muaj kev nyab xeeb, lwm tus neeg tau lees paub, thiab tag nrho cov ntaub ntawv sib pauv yog encrypted. SSH kuj muaj ob qhov kev pabcuam hloov ntaub ntawv; ib qho yog SCP, uas yog lub davhlau ya nyob twg uas siv tau zoo li CP hais kom ua; thiab lwm qhov yog SFTP, uas yog qhov kev sib tham sib cuam tshuam zoo ib yam li FTP ". Debian Administrator Phau Ntawv Qhia

"Tam sim no muaj peb feem ntau siv SSH daemon, SSH1, SSH2, thiab OpenSSH los ntawm OpenBSD folks. SSH1 yog thawj SSH daemon muaj thiab tseem yog qhov feem ntau siv. SSH2 muaj ntau qhov zoo dua SSH1, tab sis tau muab faib raws li cov ntawv tso cai qhib-kaw sib xyaw. Txawm li cas los xij, OpenSSH yog ib qho dawb dawb daemon uas txhawb nqa SSH1 thiab SSH2. Thiab nws yog, lub version ntsia ntawm Debian GNU / Linux, thaum xaiv rau nruab 'SSH' pob. Debian Security Phau Ntawv Qhia

Vim li cas thiaj siv SSH tshuab?

Yog vim li cas, SSH Yog ib network raws tu qauv uas guarantees a pauv ntaub ntawv (cov ntaub ntawv / cov ntaub ntawv) nyob rau hauv ib txoj kev nyab xeeb thiab dynamic, los ntawm tus neeg siv lub computer mus rau lub computer server.

Tsis tas li ntawd, qhov no technology muab cov txheej txheem uas suav tias yog kev ntseeg siab heevvim, hauv, cov ntaub ntawv lossis cov lus txib xa mus rau lub khoos phis tawj lub hom phiaj yog encrypted. Thiab tag nrho cov no, lav tias kev xa cov ntaub ntawv tau ua tiav hauv txoj hauv kev zoo tshaj plaws, yog li txo tau qhov kev hloov pauv tau thaum nws ua tiav, kis tau tus mob thiab txais tos.

Thaum kawg, nws tsim nyog sau cia tias SSH kuj muaj ib tug mechanism uas muaj los yog yuav tsum tau authentication ntawm cov neeg siv tej thaj chaw deb, txhawm rau xyuas kom meej tias nws tau tso cai rau kev sib txuas lus nrog lub khoos phis tawj (server). Tsis tas li ntawd, cov txheej txheem no feem ntau, los ntawm lub neej ntawd, tshwm sim ntawm theem ntawm kev siv cov terminals lossis consoles, uas yog, los ntawm I ib puag ncig.Hais kom Line Interface (CLI).

Open Secure Plhaub (OpenSSH) yog dab tsi?

Raws li cov OpenSSH official lub vev xaib, qhov program pub dawb thiab qhib no tau piav qhia raws li hauv qab no:

"OpenSSH yog cov cuab yeej txuas rau kev nkag mus rau tej thaj chaw deb siv SSH raws tu qauv. Encrypts tag nrho cov tsheb thauj mus los kom tshem tawm eavesdropping, kev sib txuas hijacking, thiab lwm yam kev tawm tsam. Tsis tas li ntawd, OpenSSH muab cov txheej txheem nplua nuj ntawm kev ruaj ntseg tunneling nta, ntau yam kev lees paub tseeb, thiab cov kev xaiv tsim nyog. "

Thiab cov hauv qab no tau ntxiv thiab nthuav dav:

"Lub OpenSSH suite muaj cov cuab yeej hauv qab no: Kev ua haujlwm nyob deb yog ua tiav ntawm ssh, scp, thiab sftp; cov gkev tswj hwm tseem ceeb khiav nrog ssh-ntxiv, ssh-keysign, ssh-keyscan thiab ssh-keygen; thiab cov pab pawg ua haujlwm nrog sshd, sftp-server thiab ssh-tus neeg sawv cev pob khoom ".

OpenSSH 9.0: Dab tsi tshiab thiab kho kab laum

Nws yog tsim nyog sau cia tias tam sim no OpenSSH yog nyob rau nws version 9.0. Tsis ntev los no tso tawm version (08/04/2022) uas nws lub ntsiab novelties yog cov hauv qab no:

  • SSH thiab SSHd: Siv Streamlined NTRU Prime + x25519 hybrid key raws li txoj kev pauv hloov pauv ("sntrup761x25519-sha512@openssh.com").
  • SFTP-Server: Ua kom "daim ntawv-cov ntaub ntawv" txuas ntxiv tso cai rau Server-sab luam ntawm cov ntaub ntawv / cov ntaub ntawv, ua raws li tus qauv tsim hauv cov qauv-ietf-secsh-filexfer-extensions-00.
  • SFTP: Ntxiv "cp" hais kom tso cai rau server-sab cov ntaub ntawv luam ua haujlwm ntawm sftp tus neeg siv khoom.

Abstract

Hauv ntej, SSH technologyFeem ntau, nws yog ib qho cuab yeej zoo thiab yooj yim uas, yog tias siv tau zoo, muaj ib qho txhim khu kev qha thiab ruaj ntseg connectivity thiab tus ID nkag mus mechanism rau lwm tus pab pawg nyob deb, txhawm rau nkag mus rau cov kev pabcuam thiab kev ua haujlwm muaj nyob hauv nws. Thiab nws qhov sib npaug dawb thiab qhib, uas yog, «Qhib Secure Plhaub » (OpenSSH) yog ib qho zoo kawg nkaus pub dawb thiab qhib lwm txoj haujlwm ntawm tib yam, dav muaj thiab siv rau tag nrho cov GNU / Linux kev faib tawm tam sim no.

Peb cia siab tias qhov kev tshaj tawm no muaj txiaj ntsig zoo rau tag nrho «Comunidad de Software Libre, Código Abierto y GNU/Linux».
