vo windows-e aj gnu/linux-e nahodne vypadava pripojenie na internet. akoze sa spusti os a nejde. vacsinou pomoze vybrat kabel a zasunut, ale niekedy to nepomoze. takmer vzdy pomoze restartovat. najskor som si myslel ze to je to fyzicky problem na konektore/porte ale zarazilo ma ze restartovanie pomaha. dakujem za pripadne odpovede.

      ked sa ti to najblizsie stane v ubuntu, skus upravit /etc/hosts tak aby tvoje hostname malo pridelenu ip adresu
      127.0.0.1 localhost server
      127.0.1.1 ubuntu7.10 ubuntu7 jablko
      

      v mojom pripade som tam doplnil "jablko" (to co je tucnym to je moje hostname), pripadne napis ake mas hostname a co mas v tom subore, toto riesenie asi nieje koser ale mne to pomohlo

        Ty koki, tento zasah akoze urobi release z dhcp servra a reset sietovej vrstvy (teda to co sa udeje pri vysunuti a zasunuti sietoveho kabla)? No, ubuntu Vista je zaujimava distribucia, skoda ze ma neblahy dopad na urcite aspekty vnimania reality.

          netreba si vsimat, hikikomori82 dava podla mojho nazoru naschval nespravne odpovede (staci si pozriet jeho prispevky).


          navrh pre admina: Nebolo by odveci zistit odkial sa pripaja a pokial je to staticka IP tak mu dat na nu ban aspon na mesiac a popripade aj zrusit ucet.

            ale neee, nehaj ho zit. bez takych ako on by bol zivot smutny a ja by som nemal do koho rypat.

            ps: k teme, nehlasi to nahodou v logu kam sa pcha vystup z dhcp klienta (asi /var/log/messages) nieco o tom ze niekto ukradol IP adresu popripade na wilde nevyskoci podobne okno? toto vyzera na helpdesk poskytovatela internetu (ak ten router nie je dokonca privatny).

      Tych dvoch pakov si nevsimaj. Mne toto riesenie pomohlo ked vytiahnem kabel tak cele ubuntu kompletne "zamrzne", hocico sa spusta 1-2 minuty. Pridal som moje hostname k tej ip-cke do /etc/hosts a odvtedy to ide v pohode aj ked je odpojeny kabel.

        on pise ze mu vypadava internet, nie ze sa mu kuse system po odpojeni internetu. on to tym docasnym odpojenim riesi.

        localhost je 127.0.0.1, tebou poskytnuta rada bola dosledkom zadratovania po zmene nazvu z "server" na "jablko". mimochodom, kto ten server vyhodil?

        ps.: pre zadavatela - ak ti to robi v viacerych os tak na tom istom hardware, tak to poukazuje bud na chybu pocitaca alebo sietoveho pripojenia. predpokladam ze si vylucil problem sietovky ako pokazeneho hardware a tym padom ostala otazka na dodavatela/poskytovatela internetu. nie, tato chyba sa s najvecsiou pravdepodobnostou netyka linuxu.

            predpokladal som ze boli vylucene problemy u poskytovatela a aj problemy hardware ale asi sa budem musiet opytat.

            boli vylucene problemy s hardware ? ta chyba na sietovke sa zacina prejavovat par sekund po starte. a bola vylucena aj chyba u poskytovatela (napriklad nevhodna kabelaz)?

            sietovky sis kedysi nevynikali stabilitou, ale to sa mozno zmenilo.

            kolko asi tak ubehlo sekund medzi nacitanim ovladaca sietovky a prvym vypadkom, tolko co akurat stihlo odpovedat dhcp?

            ps.: odporucil by som vyskusat inu sietovku (intel, 3com), najlepsie aj s inym kompom na tej interfernetovej pripojke.

              uz sa to celkom zlepsilo. vacsinou to hned ide a ked nie staci vybrat pockat par sekund a vlozit. skusim to nejako prezit a v pripade, ze sa to zhorsi skusim vymenit sietovu kartu.
