Tyle, ze ja pinguje tylko najblizszy po "zaczarowanym segmencie WARMANa"
router. Dalej moze byc gorzej.

Tez bardzo chetnie taka dyskusje bym ujrzal. Czekam na nia od bardzo
dawna. W kazdym zgloszeniu problemu do WARMANa (a bylo ich juz wiele)
prosze o podanie informacji o awarii na pl.internet.komunikaty
(przynajmniej). Nigdy jeszcze nic takiego sie nie zdarzylo...

No to ja moze wyjasnie jak to bylo :-) Nie bylo w tym nic "magicznego",
a problem lezal na sunsite, nie zas na innym urzadzeniu
sieciowym. Ustawialismy aliasy IP i troche nam to nie wyszlo -- okazuje
sie ze wiele aliasow IP na wielu fizycznych interfejsach pod Solarisem
to nie taka oczywista sprawa :-)

Tu sie zgadzam. Tym bardziej, ze nasza praca idzie na marne jezeli
ludzie nie moga z niej korzystac bez problemow.
Przypomne tez jeszcze raz, ze do wezla Ochockiego sieci WARMAN
podlaczone jest wiele instytucji. Problem nie dotyczy tylko ICM, lecz
sporej czesci sieci Warszawskiej.
