Dotaz: Kubuntu 9.10 -> pomale DNS/DHCP

[NeoV]

Ahojte...

Obcas mam problem uz na 2och roznych strojoch s Kubuntu9.10 - Pri dlhsom behu PC zacne siet velmi pomaly reagovat na dotazy cez nazvy hostov... tj. napr. browser mi niekolko sekund lookupuje host kym vobec zacne s nim komunikovat...

Porblem je globalny v OS:

$ ping www.l.google.com

4 jednoduche dotazy trvali 47sekund !!!

Ak vsak zadam ping priamo na IP tak nie je ziaden problem:

$ ping 74.125.87.104

Ja si nemuzu pomoc, ale az na hodnotu "time", ktera ukazuje 2 sekund u dotazu pres DNS nevidim zadne rozdily dotazu.. kupodivu i prumery odpovidaji hodnotam jednotlivych pingu..jen ten "time"., nechapu..
