ping: unknown host [nazwa kompa w sieci lokalnej]
komp, 2 sieciowki, eth0 dostaje net, eth1 rozprowadza po sieci lokalnej. Ping do wp.pl dziala - ogolnie pingi do internetu dzialaja. Pingi w sieci lokalnej dzialaja tylko po adresach IP, po nazwach netbios juz nie. W sambie wins wlaczone. Na firewallu komunikacja odblokowana.
wklejam moje hosts i resolv.conf

Re: ping: unknown host [nazwa kompa w sieci lokalnej]
wins nie jest dns i nie wydaje mi sie aby nie windowsowe narzedzia uzywaly go jako dns ... jezeli chesz pingoqwac po nazwach i sa one statycznie powiazane z ip najlepiej pouzupelniac sobie /etc/hosts

Re: ping: unknown host [nazwa kompa w sieci lokalnej]
wykorzystaj nbtscan... wynik zapisz do pliku, eksportuj do arkusza kalkulacyjnego, obrob odpowiednio w nim i zapisz jako plik /etc/hosts

Re: ping: unknown host [nazwa kompa w sieci lokalnej]
wszystko pieknie.. ok ok da sie to tak "obejsc"... ale jak podepne jakiegos lapka pod siec to musze to znow edytowac... sadzilem ze linux jako router spokojnie moze zmieniac nazwy ip na netbios i ich uzywac...
tak czytam i czytam i czy za odnajdywanie tych nazw nie powinie byc odpowiedzialny bind poprzez "in-addr.arpa" ??
bo jak walnę nslookup 10.0.0.3 to mi wylpuwa
Kod:
Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find 3.0.0.10.in-addr.arpa: NXDOMAIN

Re: ping: unknown host [nazwa kompa w sieci lokalnej]
tylko ze:
1. bind jest serwerem dns ... a jak pisalem wins to nie dsn - jest to pomysl MS a nie standard internetowy
2. domena in-addr.arpa jest odpowiedzialna za odwrotny DNS czyli zamiane nazw ip na nazwy domenowe komputerow ale (jeszcze raz zaznacze) w systemie DNS
3. nazwy netbiosowe nie sa naturalne dla srodowisk posixowych i watpie aby byly bezposrednio obsugiwane przez resolver
4. mozesz kombinowac aby samba exportowala do hosts lub sprobowac zrobic to:
Kod:
ping `nmblookup NAZWA`
jezeli bedzie to dzialalo mozesz sobie zdefiniowac alias np ping-local i go uzywac
