tso tawm ib qho dawb cross-platform UNIX zoo li operating system . Txoj haujlwm OpenBSD tau tsim los ntawm Theo de Raadt hauv 1995 tom qab nrog NetBSD cov neeg tsim khoom, raws li qhov tshwm sim ntawm Teo tau raug txwv tsis pub nkag mus rau NetBSD CVS chaw cia khoom. Tom qab no, Theo de Raadt thiab ib pab pawg neeg zoo li lub siab xav tau tsim ib qho tshiab qhib kev ua haujlwm raws li NetBSD qhov chaw ntoo, lub hom phiaj tseem ceeb ntawm kev txav mus los ( 13 hardware platforms), kev tsim qauv, kev ua haujlwm kom raug, kev ruaj ntseg ruaj khov thiab cov cuab yeej cryptographic sib xyaw. Tag nrho cov installation loj OpenBSD 6.6 lub hauv paus system yog 460 MB.
Ntxiv rau qhov kev ua haujlwm ntawm nws tus kheej, qhov project OpenBSD paub txog nws cov khoom, uas tau dhau los ua ntau yam hauv lwm lub tshuab thiab tau ua pov thawj lawv tus kheej los ua ib qho kev daws teeb meem zoo tshaj plaws. Ntawm lawv: ( OpenSSL), , pob ntawv lim , routing daemons , NTP server , mail server , text terminal multiplexer (zoo ib yam li GNU screen) , dab nrog rau kev siv ntawm IDENT raws tu qauv, BSDL lwm txoj rau GNU groff pob - , raws tu qauv rau kev teeb tsa kev ua txhaum cai CARP (Common Address Redundancy Protocol), lub teeb yuag , cov ntaub ntawv synchronization utility .
ntsiab :
- Cov khoom siv hluav taws xob suav nrog , kom hloov kho qhov system mus rau qhov kev tso tawm tshiab. Sysupgrade rub tawm cov ntaub ntawv tsim nyog rau kev txhim kho, txheeb xyuas lawv siv , theej cov ramdisk bsd.rd rau bsd.upgrade thiab pib lub kaw lus reboot. Lub bootloader, tau kuaj pom lub xub ntiag ntawm bsd.upgrade, pib rub nws thiab hloov kho lub kaw lus. Rau cov ceg yav dhau los ntawm OpenBSD 6.5, syspatch tau npaj los ntxiv sysupgrade thiab tso cai rau koj siv cov khoom siv no los txhim kho koj lub cev rau OpenBSD 6.6 ntawm amd64, arm64 thiab i386 architectures los ntawm kev ua "syspatch & & sysupgrade";

- Lub peev xwm xa cov pob ntawv tau txais mus rau lub network pawg hauv batch hom tau ntxiv rau txhua tus tsav tsheb wireless, ua ntau pob ntawv ib zaug hauv ib qho kev cuam tshuam;
- Txhim kho cov ntaub ntawv system cache kev ua tau zoo ntawm cov khoos phis tawj nrog AMD64 architecture;
- Txhim kho startx thiab xinit functionality ntawm niaj hnub systems siv inteldrm, radeondrm thiab amdgpu graphics tsav;
- Lub unveil system hu tau raug txhim kho kom muab cov ntaub ntawv nkag mus cais tawm. Tus naj npawb ntawm cov ntawv thov los ntawm lub hauv paus system uas tiv thaiv kev siv unveil yog siv tau nce mus rau 77;
- Lub getrlimit, setrlimit, nyeem thiab sau cov xov tooj hu, nrog rau cov cai rau kev nkag mus rau cov peev txheej txwv thiab hloov cov ntaub ntawv txoj haujlwm, tau raug tshem tawm los ntawm kev thaiv thoob ntiaj teb;
- Txhim kho txoj hauv kev los thaiv Spectre vulnerabilities hauv Intel CPUs. Ntxiv kev tiv thaiv los ntawm MDS (Microarchitectural Data Sampling) chav kawm hauv Intel processors;
