To powyższe jest przy przesłaniu pinga z hosta przez router i przez modem. Jeśli pinguję z hosta router, pingi są normalne i bez duplikatów. Jeśli wbiję na router przez ssh i pingnę z routera wp.pl, to dostaję log jak wyżej.

Coś jest nie tak w konfiguracji routera czy modem nawala?

Z tego co zauważyłem, to reset modemu zwykle naprawia tą sytuację i duplikaty znikają i net działa normalnie ale kolejny reset może znów coś schrzanić i tak w kółko. Jeśli już modem się załączy i wszystko działa jak należy, to do chwili resetu/wyłączenia modemu, net działa w porządku.

Rozmawiałem niby z moim isp i on coś tam mówił, że to może być przez router. Ja nigdy się z tymi duplikatami nie spotkałem, więc nie wiem zbytnio jak ugryźć tę sytuację.

Odp: Duplikaty pakietów

Wygląda na to, że ten problem dotyczy tylko linuxów. Podłączyłem laptopa z win7 i tam nie ma duplikatów pakietów. Zrobiłem kilka testów i udało mi się ustalić, że:

jeśli na routerze są duplikaty, na laptopie z win7 ich nie ma
jeśli na routerze są duplikaty, na laptopie z debianem również są duplikaty
jeśli na routerze są duplikaty, na laptopie z systemem live (ubuntu albo debian), też są duplikaty.

Może jakieś ustawienia w kernelu linuxa powodują takie objawy? Albo może też pingi z win7 i linuxa są inaczej przetwarzane?

Tak jak by windows akurat pokazywał jakieś dodatkowe informacje. Naprawdę wierzysz w to co windows pokazuje? smile Oni tam wszystko po swojemu napisali.

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

Ja tam się nie znam na windowsie -- nie używałem go od 5-6 lat, tak tylko pożyczyłem by zobaczyć czy tam też pokaże duplikaty.
