zdravim
nainstaloval som si ubuntu 7.04, ale internet mi akosi nejde-nenacita ziadne stranky (skusal smo www.ubuntu.cz(com), stv.sk, cnn.com, travian.sk IBA www.google.com(sk) - vyhlada aj zadany vyraz, ale ked kliknem na link uz nefunguje net aj gmail.com - som sa v pohode prihlasil do svojho mailu, precital spravy.
Pridavam zopar vypisov:

nejde net-ziadne stranky len google!?!?

pokiaľ tvoj poskytovateľ internetu nepodporuje IPv6, tak ho skús vypnúť.

a to som si fcera po skompilovani mojho prveho programiku pod linom myslel ze som king of the castle.. :D
a po tomto prispevku si mozem povedat ze ¨koho zabilo¨ ?? ale aspon si to povytlacam vsetko a dobre bude tam oko poslat ked si nebudem vediet rady
iptabes -L
a
iptables -L -t nat
Kedze ti resolvuje spravne a ping prelezie, tak problem bude niekde inde.
Zaplatil si ucet providerovi?
Mas vypnuty proxy?
Pozri sa do firefoxu a este sa pozri prikazom
echo $http_proxy
Nevyzaduje tvoj provider proxy server? {Pozri sa vo widlach, ci tam nemas nastaveny proxy}
iptables -L
Chain INPUT (policy ACCEPT)

Ucet a taketo veci su OK, ved vo windovse ide net dobre.
Proxy nemam nastavene ani vo windovse nieje. Prikaz
echo $http_proxynevypisal nic.links http://www.linuxos.sk
alebo
wget http://linuxos.sk
Teoreticky by si mohol poslat co ti vypisal ten wget ked ti nic nestiahne.
po zadani
wget http://linuxos.sksom dostal:

..a tak to ostane..aj ked som dal stahovat niejaky balisek-soft cez terminal....

sudo ifconfig eth0 mtu 1492
to michal6130: vies trosicku blizsie objasnit v com bola chyba?
to moderator: mozte temu oznacit ako vyriesenu
TCP/IP: 1492 B toto si si nastavil ako Maximum Transmission Unit
PPP hlavika:+2
PPPoE hlavicky: +6
Velkost ramca: 1500
A preto musi byt MTU maximalne 1492, aby sa tam zmestili este aj PPPoE hlavicky. Do ATM siete sa zapuzdruje aj 18B, ktore su tvorene ethernetovymi hlavickami, ale tie nas teraz nezaujimaju.
Ked si chces este trosku zvysit priepustnost tvojho ADSL pripojenia tak si nastav MTU na 1454.
..na itnetrnet sa nepripajam cez DSL, ale cez mikrovlnku....
Najprv si pozri /etc/network/interfaces
potom si precitaj
man 5 interfaces
a potom si do /etc/network/interfaces pripis k tomu eternetu dalsi riadok
mtu 1492
Takze ti to bude vyzerat takto:
auto eth0 iface eth0 inet static address 172.16.137.10 netmask 255.255.255.0 gateway 172.16.137.254 mtu 1492Dufam ze to bude fungovat
Akurat neviem co si myslel tym man 5 interfaces, ale neva:)
man 5 interfaces
tak sa docitas o vsetkych parametroch ktore mozes do toho suboru dopisat, je to zaujimave citanie a hlavne nemusis kvoli kazej blbosti prznit init scripty, co je podla mojho nazoru blbost, lebo menit sa maju konfiguraky a nie init scripty.
