OpenSSH seti yezvishandiso inobvumira kuvharirwa kutaurirana pamusoro petiweki, uchishandisa iyo SSH protocol.
Akazivisa kutanga kwe vhezheni itsva yeOpenSSH 9.7, shanduro inotanhamara mairir kutanga nekushandiswa kweshanduko kutarisira kusashanda kweramangwana re makiyi anobva pane DSA, pamwe nekuitwa kwemamwe maficha matsva, bug kugadzirisa uye nezvimwe.
Kune avo vasingazive nezve OpenSSH, iwe unofanirwa kuziva izvozvoIyi ndeye yemahara uye yakavhurika sosi kushandiswa kweSSH protocol (Chengetedza Shell) inopa ese ari maviri mutengi uye sevha mashandiro ekuchengetedza kutaurirana pamusoro petiweki. Iyo SSH protocol inonyanya kushandiswa kuwana kure kure masisitimu uye kuendesa mafaera zvakachengeteka pakati pemasisitimu, kunyanya munzvimbo dzenetiweki uko kuchengetedzeka ndiko kunonyanya kunetseka.
Chii chitsva mu OpenSSH 9.7?
Chimwe chezvakakosha zveiyi vhezheni nyowani yeOpenSSH 9.7 uye sezvambotaurwa pakutanga, kufambira mberi kune ramangwana rekubvisa chirongwa cheiyo DSA siginecha algorithm uye kunyangwe OpenSSH 9.7 inochengeta default kuvaka neDSA rutsigiro Parizvino, inopa sarudzo yekudzima DSA panguva yekuunganidza.
Zvakakosha kuziva kuti, nekusingaperi, Kushandiswa kwemakiyi eDSA kwakamiswa muna 2015, asi iyo kodhi yekutsigira DSA yakachengetwa nekusarudzika uye yakabvumidzwa DSA activation kuburikidza nekugadzirisa. Muchikamu chinotevera, yakarongwa muna June, kuvaka modhi ichachinja kudzima DSA nekukasiraa, uye OpenSSH inoronga kubvisa rutsigiro rweDSA kutanga kwa2025
Sarudzo iyi ndeye Iyo DSA algorithm yaive yakakosha pakuitwa muSSHv2 protocol nekuda kwekurambidzwa patent panguva yekusikwa kwayo uye kubvumidzwa. Zvisinei, Nekufamba kwenguva, mapatent ane chekuita neRSA apera, uye maalgorithms akadai seECDSA, ayo anopa kuita zviri nani uye chengetedzo pane DSA, uye EdDSA, iyo yakatonyanya kuchengeteka uye nekukurumidza kupfuura ECDSA, yakasumwa. Uku kufambira mberi kwetekinoroji kwakatungamira kusarudzo yekutarisira kudzikiswa kweDSA muOpenSSH.
Pamusoro peiyo DSA inoenderana shanduko, OpenSSH 9.7 inounza akati wandei kuvandudzwa uye mamwe maficha uye imwe yeiyi gadziridzo ndeye kuunzwa kwerudzi rutsva rwenguva yekupedza mu ssh uye sshd, , que Inoitwa nekutsanangura kukosha "pasi rose" muChannelTimeout rairo. Iyi mhando yenguva yekupedza inotarisisa nzira dzese dzakavhurika uye ichavhara ese akavhurika machanera kana pasina traffic pane chero yadzo panguva yakatarwa. Ichi chinhu chinobatsira mumamiriro ezvinhu apo iwe une akawanda machaneti akavhurika, senge masesheni uye kutumira, uye iwe unoda kuavhara kana akaramba asingashande kwenguva yakareba.
Kune rimwe divi, OpenSSH 9.7 Inosanganisirawo akati wandei gadziriso yebug kuvandudza kugadzikana uye kuita. Aya magadziriso anovhara nzvimbo dzakadai seyekugadziriswa kwekuongorora, kubata chiratidzo, uye kuvandudza kudyidzana kuyedzwa kunopesana nemamwe maSSH kuita.
Yeimwe shanduko Chii chinomira pachena kubva pane iyi vhezheni itsva yeOpenSSH 9.7
- OpenSSH inosanganisira kuvandudzwa kwakakosha mukuyedzwa kwekuenderana nePuTTY chirongwa.
- Panyaya yekutakurika, kuvandudzwa kwakaitwa kune yakatyoka toolchain yekuona uye iyo yekukanganisa meseji yakagadziridzwa mune mamwe mamiriro, zvichibatsira kune yakapfava uye inoshanda zvakanyanya mushandisi ruzivo.
Finalmente kana iwe uchifarira kuziva zvakawanda nezvazvo nezve iyi vhezheni nyowani, iwe unogona kutarisa iyo ruzivo nekuenda kunotevera chinongedzo.
Maitiro ekuisa OpenSSH 9.7 paLinux?
Kune avo vanofarira kugona kuisa iyi nyowani vhezheni yeOpenSSH pane avo masisitimu, nekuti izvozvi vanogona kuzviita kurodha pasi kodhi kodhi yeiyi uye vachiita muunganidzwa pamakomputa avo.
Izvi zvinodaro nekuti iyo vhezheni nyowani haisati yaverengerwa mumachengeterwo ezvekutanga zvekuparadzirwa kweLinux. Kuti uwane iyo kodhi kodhi, iwe unogona kuita kubva ku next link.
Waita kurodha pasi, ikozvino tava kuzobvisa pasuru yacho nemirairo inotevera
tar -xvf openssh-9.7.tar.gz
Isu tinopinda dhairekitori rakagadzirwa:
cd openssh-9.7
Y tinogona kuumbiridza ne inotevera mirairo:
./configure --prefix=/opt --sysconfdir=/etc/ssh make make install
