Mwepụta nke OpenBSD 6.5

Hụrụ ọkụ ntọhapụ nke free, cross-ikpo okwu UNIX yiri sistemụ arụmọrụ Mepee OpenBSD 6.5. Theo de Raadt tọrọ ntọala OpenBSD na 1995, ka emechara esemokwu ya na ndị mmepe NetBSD, n'ihi nke a jụrụ Teo ịnweta ebe nchekwa NetBSD CVS. Mgbe nke a gasịrị, Theo de Raadt na otu ndị nwere ụdị echiche ahụ mepụtara sistemụ arụmọrụ mepere emepe ọhụrụ dabere na osisi NetBSD, ebumnuche bụ isi bụ ibugharị (na -akwado ya 13 ngwaike nyiwe), nhazi ọkwa, ọrụ ziri ezi, nchekwa na-arụ ọrụ yana ngwa ọrụ cryptographic agbakwunyere. Nha nrụnye zuru oke Foto ISO Sistemụ ntọala OpenBSD 6.5 bụ 407 MB.

Na mgbakwunye na sistemụ arụmọrụ n'onwe ya, a maara ọrụ OpenBSD maka ihe mejupụtara ya, bụ nke na-agbasawanye na sistemụ ndị ọzọ ma gosipụta na ha bụ otu n'ime ihe ngwọta kachasị mma na nke dị elu.

N'ime mgbanwe ndị a ma ama: ewebata ụdị bgpd nwere ike ibugharị, gbanwee ka ọ rụọ ọrụ na OS ndị ọzọ, ewepụla ojiji nke Xenocara na tcpdump ohere mgbọrọgwụ, a na-enye njikọ LDD site na ndabara maka amd64 na i386, nkwado MPLS. emeziwanyewanye nke ọma, yana nchebe megide nrigbu site na iji usoro azụghachi azụ ka ewusiri ike, agbakwunyela ihe nkesa DNS kachasị mfe, etinyela ihe nchọta omume na-akọwaghị n'ime kernel, yana mmejuputa iwu nke rsync nke anyị nwere. ewebata.

Main ndozi:

  • Mgbe ị na-ewu maka amd64 na i386 architectures, LDD linker nke LLVM mepụtara na-eji ndabara. Maka ihe owuwu mips64, agbakwunyela nkwado maka iwu ụlọ iji Clang;
