kobliha.fuj.com) jde bez problemu, na serveru ping na hlavni domenu fuj.com jde taky. Ale kdyz chci z klientskeho pc dat ping na fuj.com tak mi napise ze nenasel tuto domenu, ale ping na maso.fuj.com jde. Nevite kde by mohl byt problem? Pri startu bindu neni zadna chybova hlaska. Ve forwardes mam dns sveho poskytovatele internetu. A uz fakt nevym ke by mohla byt chyba. Pokud by to bylo nutne dam sem i konfiguraky bindu. v /etc/hosts mam (mimo localu)172.16.2.1 srv.fuj.com srv 213.164.xxx.xxx fuj.comV
host.conf mam aby uprednostnil bind.
V resolv.conf mam search fuj.com nameserver 127.0.0.1
tcpdump jsem jiz zkousel ale bohuzel nic prevratneho z nej nevylezlo, dostal pozadavek a vratil tazately s tim ze u tazatele to hodilo ze nezna fuj.com. I pri uplne vypnutym firewallu se to chova stejne zadna zmena. Kudla to je divne vse jede net jede vse v poho. JInak na klientskem PC s XP kdyz to testnu pres nslookup tak mi pri set type=a fuj.comhodi
server: srv.fuj.com adresa 172.16.2.1 nazev: fuj.com
