Vagadziri veOpenBSD vakaburitswa mazuva mazhinji apfuura kuvhurwa kwe vhezheni itsva inotakurika yeiyo nzira pasuru OpenBGPD 6.7 iyo inozivikanwa nekukwanisa kushandiswa mune anoshanda masisitimu asiri OpenBSD uye izvo Inokutendera iwe kushandisa yakajairika chinangwa komputa se router.
OpenBGPD iri daemon reUnix iyo inoshandisa, kuburikidza neyemahara software, vhezheni yechina yeBorder Gateway Protocol uye nekuda kweichi muchina unokwanisa kuchinjisa nzira nemamwe masisitimu uchishandisa BGP. Kuona kutakurika, zvikamu zvekodhi kubva kuOpenNTPD, OpenSSH uye LibreSSL mapurojekiti akashandiswa. Pamusoro peOpenBSD, yakazivisa rutsigiro rweLinux uye FreeBSD.
Nezve OpenBGPD
Iyi suite yakagadzirwa seimwe nzira yemapakeji akaita seQuagga, GPL ine rezinesi yeLinux-based routing suite iyo isingakwanise izvo zvinoda chirongwa uye nemhando yepamusoro.
Iwo magadzirirwo ezvinangwa zveOpenBGPD anosanganisira kuve akachengeteka, akavimbika, uye akajeka zvakakwana kune vazhinji vashandisi, zvese zviri muhukuru uye nekushandisa ndangariro.
Mutauro wekumisikidza unofanirwa kuva nesimba uye nyore kushandisa. Inofanira zvakare kukwanisa kubata nekukurumidza mazana ezviuru ezvinyorwa zvematafura nenzira yekurangarira inoshanda.
Iko kuvandudzwa kweOpenBGPD inotsigirwa nemunyori weinternet registrar RIPE NCC, ndiani anofarira kugadzira mashandiro eOpenBGPD akakodzera kushandiswa pamaseva ekugadzirisa nzira dzekupindirana kwevatakuri (IXPs) uye mukugadzira imwe nzira yakakwana kune iyo BIRD package (kubva kune dzimwe nzira dzakavhurika nekuitwa kweprotocol BGP inotaura FRRouting, GoBGP, ExaBGP uye Bio-Routing mapurojekiti).
Kana uchigadzira OpenBGPD, chinangwa ndechekuona mwero wepamusoro wekuchengetedzeka uye kuvimbika. Kudzivirirwa, kusimbiswa kwakasimba kwekururamisa kweese parameter kunoshandiswa, nzira dzekutarisa kuteedzana neyakaganhurirwa miganho, kupatsanurwa kweropafadzo uye kurambidzwa kwekuwana kune system kufona.
Pakati pezvakanaka zvakare iri nyore syntax yemutauro wekumisikidza, uyel Kuita kwakanyanya uye kugona kurangarira (semuenzaniso, OpenBGPD inogona kushanda nematafura ekurongedza anosanganisira mazana ezviuru zveanopinda).
Iyo purojekiti inotsigira mazhinji eBGP 4 maratidziro uye inoenderana nezvinodiwa zveRFC8212, asi haiyedze kugamuchira hukuru uye inonyanya kutsigira inozivikanwa uye inozivikanwa mabasa.
Chii chitsva muOpenBGPD 6.7?
Mune iyi vhezheni nyowani yakapihwa kutanga kutsigirwa kweJSON kubuditsa kune bgpctl utility, kunze kweizvozvo mu bgpctl, iwo 'show muvakidzani' wekuraira unowedzera kuratidza macounter eakagashira uye akaisa prefixes, pamwe neyakaganhurwa kukosha "max-prefix kunze".
Imwe shanduko ndeyekuti iyo chaiyo kuunganidzwa kwematafura e ROA (Path sosi mvumo) ine prefix / sosi mapairi senge mune chinhu chine kureba kukosha 'maxlen', iri mubgpd.conf IPv4 uye IPv6 kero dzinogona kumisikidzwa panguva imwe chete mukero yekero yekuraira mumablock "boka".
Yeimwe shanduko:
- Iyo "max-prefix {NUM} kunze" chivakwa chakawedzerwa kune bgpd.conf kudzikamisa huwandu hweakashambadza prefixes kudzivirira kudonhedza tafura dzese;
- Izvo zviziviso zvinosanganisira ruzivo nezvechakakonzera nested zvikanganiso. Iwo "bgpctl ratidza muvakidzani" rairo inopa kuburitsa kwechikonzero chekukanganisa kwekupedzisira kugamuchirwa;
- Zvechokwadi "zvine mutsigo kurodha patsva" mashandiro, zviremberi zvakanyorwa zvinoiswa muAdj-RIB-Out tafura, iyo inochengeta ruzivo nezve nzira dzakasarudzwa neiyo BGP router yemunharaunda kushambadza migwagwa yakakwana kune vezera;
- Wakawedzera kugona kwekuvaka OpenBGPD uchishandisa bison parser package pasina kuvapo kwebacac;
- Yakawedzerwa sarudzo "-runstatedir", iyo yaunogona kuona nzira yeku bgpctl.sock;
- Iyo yekumisikidza script yakacheneswa kumusoro kuvandudza kutakurika.
Chekupedzisira, kune avo vanofarira iyi vhezheni, vanofanirwa kuziva izvo Iyo yatove yakaedzwa paDebian 9, Ubuntu 14.04+, uye FreeBSD 12.
Kana iwe uchida kutora mapakeji kana kudzidza zvakawanda nezvazvo, unogona kutarisa webhusaiti yepamutemo. Iyo yekubatanidza ndeiyi.
