Predgovor<\/h3>\n

\n\"Svoj Za osebne potrebe sem postavil VSphere, na katerem obrnem virtualni usmerjevalnik in Ubuntu stre\u017enik kot medijski stre\u017enik ter \u0161e kup drugih uporabnih stvari, ki morajo biti dostopne iz interneta. Vendar pa je te\u017eava v tem, da moj ponudnik zara\u010dunava stati\u010dni IP, ki ga je mogo\u010de uporabiti za bolj koristne stvari. Zato sem uporabljal kombinacijo ddclient + cloudflare. <\/p>\n

Vse je bilo v redu, dokler ddclient ni prenehal delovati. Malo raziskav me je pripeljalo do spoznanja, da je \u010das za hitre re\u0161itve, saj je iskanje te\u017eave postalo preve\u010d \u010dasa. Na koncu se je vse zaklju\u010dilo v majhnem demonu, ki enostavno deluje, in prav to je bilo vse, kar sem potreboval.
\nTisti, ki jih zanima \u2013 dobrodo\u0161li pod kat.
\n<\/a><\/noindex><\/p>\n

Uporabljena orodja in kako \u201eto\u201c deluje<\/h3>\n

\nTorej, najprej sem na spletni strani cloudflare izvedel vse, kar potrebujem vedeti o API<\/a><\/noindex>. In \u017ee sem se pripravljal, da izvedem vse v Pythonu (po spoznanju s Python-om ga vse pogosteje uporabljam za preproste naloge ali kadar potrebujem hitro prototipiranje), ko sem naletel na skoraj kon\u010dno implementacijo.
\nNa splo\u0161no je bila kot osnova vzeta zavija\u010da python-cloudflare<\/a><\/noindex>.<\/p>\n

Vzel sem enega izmed primerov za posodobitev DNS in dodal uporabo konfiguracijske datoteke ter mo\u017enost posodabljanja ve\u010d A zapisov v okviru obmo\u010dja ter seveda neomejeno \u0161tevilo obmo\u010dij.<\/p>\n

Logika je naslednja:<\/p>\n

    \n
  1. Skript dobi iz konfiguracijske datoteke seznam obmo\u010dij in po njih prehaja v zanki<\/li>\n
  2. V vsakem obmo\u010dju skript v zanki preide \u010dez vsak DNS zapis tipa A ali AAAA ter preveri javni IP z zapisom<\/li>\n
  3. \u010ce se IP razlikuje \u2014 ga spremeni, \u010de ne, presko\u010di iteracijo zanke in preide na naslednjo <\/li>\n
  4. Zaspi za \u010das, naveden v konfiguraciji<\/li>\n<\/ol>\n

    <\/p>\n

    Namestitev in nastavitev<\/h3>\n

    \nVerjetno bi bilo mo\u017eno narediti tudi .deb paket, vendar se v tem ne spoznam, pa tudi ni tako zelo zapleteno.
    \nPostopek sem kar podrobno opisal v README.md na     strani repozitorija<\/a><\/noindex>.<\/p>\n

    Ampak za vsak slu\u010daj bom to opisal v ru\u0161\u010dini s splo\u0161nimi besedami:<\/p>\n

      \n
    1. Prepri\u010dajte se, da imate name\u0161\u010den python3 in python3-pip, \u010de ne \u2013 namestite (v Windows se python3-pip namesti skupaj s Pythonom)<\/li>\n
    2. Kloni ali prenesi repozitorij<\/li>\n
    3. Namestite potrebne odvisnosti.\n
      python3 -m pip install -r requirements.txt<\/code><\/pre>\n
      \n<\/li>\n
    4. Za\u017eenite namestitveni skript
      \nZa Linux:<\/p>\n
      chmod +x install.sh\nsudo .\/install.sh<\/code><\/pre>\n
      \nZa Windows: windows_install.bat\n<\/li>\n
    5. Uredite konfiguracijsko datoteko
      \nZa Linux:<\/p>\n
      sudoedit \/etc\/zen-cf-ddns.conf<\/code><\/pre>\n
      \nZa Windows:<\/p>\n
      Odprite datoteko zen-cf-ddns.conf v mapi, kjer ste namestili skript.<\/p>\n
      To je obi\u010dna JSON datoteka, po postavkama ni\u0161ta jednostavno \u2013 posebno sam opisao kao primjer 2 razli\u010dite zone u njoj.\n<\/li>\n<\/ol>\n
      <\/p>\n
      \u0160to se skriva iza instalatera?<\/h4>\n
      \ninstall.sh za Linux:<\/p>\n
        \n
      1. Kreira se korisnik za pokretanje demona, bez stvaranja korisni\u010dkog direktorija i mogu\u0107nosti prijave.\n
        sudo useradd -r -s \/bin\/false zen-cf-ddns<\/code><\/pre>\n
        \n<\/li>\n
      2. Stvara se datoteka za zapisivanje loga u \/var\/log\/<\/li>\n
      3. Postavljamo vlasnika datoteke loga nedavno stvorenog korisnika<\/li>\n
      4. Kopiraju se datoteke na svoja mesta (konfiguracijska datoteka u \/etc, izvr\u0161na datoteka u \/usr\/bin, datoteka usluge u \/lib\/systemd\/system)<\/li>\n
      5. Aktivira se usluga<\/li>\n<\/ol>\n
        \nwindows_install.bat za Windows:<\/p>\n
          \n
        1. Kopira izvr\u0161nu datoteku i datoteku konfiguracije u korisnikom odre\u0111enu mapu<\/li>\n
        2. Kreira zadatak u planeru za pokretanje skripte pri pokretanju sistema
          \nschtasks \/create \/tn \"CloudFlare Update IP\" \/tr \"%newLocation%\" \/sc onstart<\/code>\n<\/li>\n<\/ol>\n
          \nNakon promene konfiguracije, skriptu treba ponovo pokrenuti, u Linuxu je to jednostavno i poznato:<\/p>\n
          sudo service zen-cf-ddns start\nsudo service zen-cf-ddns stop\nsudo service zen-cf-ddns restart\nsudo service zen-cf-ddns status\n<\/code><\/pre>\n
          \nza Windows \u0107ete morati da ubijete proces pythonw i ponovo pokrenete skriptu (veoma mi se ne da pisati uslugu za Windows na C#):<\/p>\n
          taskkill \/im pythonw.exe<\/code><\/pre>\n
          \nTime je instalacija i pode\u0161avanje zavr\u0161eno, koristite sretan.<\/p>\n
          Za one koji \u017eele da vide ne ba\u0161 lijep Python kod, evo repozitorij na GitHub<\/a><\/noindex>.<\/p>\n
          MIT licenca, tako da radite s tim \u0161to \u017eelite.<\/p>\n
          P.S.: Razumem da je ispalo malo improvizovano, ali se odli\u010dno nosi sa svojim zadatkom.<\/p>\n
