[linux] CLOSE_WAIT

[Bohdan Spes]

Zdravim.


	Programatorsky problem. Jeden znamy vyvija monitorovaci soft. Ten robi to, 
ze na hostovi, ktory ma byt monitorovany ma program, ktory vlastne lokalne 
kontroluje napr apache. Monitorovaci server sa vzdy pyta klienta (na hostovi) 
ci bezi apache. Vcelku mu to funguje , as ked to nainstaloval na moju masinu 
tak mu to pada. Problem je ten, ze my sme pripojeni nejakou malou mikrovlnkou 
a ked robim ping, tak asi 10% paketou je lost a asi 5 % paketov je 
duplicitnych. Provider tvrdi, ze je to normalne. Takze teraz ten jeho soft 
nechava v kerneli takyto bordel

Vypis z netstatu -t

tcp        9      0 startgate:10481         212095016222.bagge:4942 CLOSE_WAIT

Ako keby sa stracali nejake pakety na uzavretie spojenia. A to nie je vsetko. 
Teraz to najzaujimavejsie. Ked stopne svoj program, tak v kerneli to ostane. 
As ked stopne apache as potom to zmizne. Neviete niekto, kde by mohol byt 
problem ?
