podivne chovani apt-get (pres proxy)

Mam korektne nastavene pripojeni pres proxy server.

Prvni spusteni apt-get update probehne ok a vsechny indexy balicku z ulozist se mi stahnou.

root@darkstar:~ # apt-get update
Get:1 http://security.ubuntu.com warty-security/main Packages [3648B]
Get:2 http://security.ubuntu.com warty-security/main Release [102B]
Get:3 http://security.ubuntu.com warty-security/restricted Packages [20B]
Get:4 http://security.ubuntu.com warty-security/restricted Release [108B]
...

Pokud se pokusim spustit znovu (po 5min.), aniz bych se dotknul jakehokoliv nastaveni, dostanu toto:

 root@darkstar:~ # apt-get update
Err http://security.ubuntu.com warty-security/main Packages
  Connection failed
Err http://security.ubuntu.com warty-security/main Release
  Connection failed
Err http://security.ubuntu.com warty-security/restricted Packages
  Connection failed
Err http://security.ubuntu.com warty-security/restricted Release
  Connection failed
...

Nechapu

Pritom muzu stale bez problemu pomoci apt-get installovat a upgradovat, jenom to stazeni indexu zacne fungovat az treba druhy den :-(

Pretizenim serveru ulozist to neni, prislusne soubory lze bez problemu stahnout pomoci wget nebo web clienta(Firefox).

Cim by to mohlo byt ? Loguje apt-get nekam detailnejsi zaznamy o pokusech o spojeni, ze kterych by se to dalo zjistit ?

Diky
