Dotaz: problem se spojenim na server

[hates]

Nevite nebo nesetkal se nekdo s problemem kdy pokud nekomunikuji urcitou dobu se serverem tak spojeni nahle spadne a nejde se na server ani dopingnou. po urcite dobe se ale spojeni zase obnovi. pripada mi to jako kdyz by se server uspal a probudi ho az nejaky proces ktery vykona cron. pak zase spojeni jde bez problemu. pokud se na nej prihlasim pres ssh a muzu zase normalne pracovat. jak prosim zjistim jestli se system uspava a jestli ano tak jak to vypnu. diky za kazdy namet. uz si s tim opravdu nevim rady

Co je ten server zač?

[hates]

distro gentoo kernel 2.6.11 je tam rozbehany apache.

[Zdeněk Burda]

Jaké jádro používáš? Jak máš nastavené ACPI/APM a podobně? Jde o nastavení v BIOSu i v systému. Mrkni se do logů a do výpisu dmesg. Co tam máš za síťovku(jaký ovladač)? Jedna má síťovka dělala to samé, vždy se na chvíli odmlčela.

[hates]

jadro tam je 2.6.11 distribucni. ACPI je zakompilovane primo do jadra. v logu se nic neukaze tam jsem hledal jako prvni. sitovka s chipsetem Realtek 8139 v PCI. k nastaveni v biosu se momentalne nedostanu to az v pondeli.

[David Jaša]

Výpis se mě zdá OK (i když to ještě nemusí znamenat, že je OK ). Neběží některý ze "šetřících" daemonů (cpufreqd, powernowd, ...)?

[hates]

zadny z takovych demonu mi tam urcite nebezi

[hates]

tak mam tenhle problem porad a nejak se mi to nepodarilo vyresit. momentalne to bezi s nouzovkou a to je ta ze necham na serveru bezet ping na nejaky jiny PC. to proto jen aby komunikovala sitovka. Pokud ale ten ping vypnu server cca za hodinu prestane komunikovat se svetem a uz se mi ani nijak nepodari z venku s nim navazat kontakt jedina moznost je jit k serveru a profouknout linku z nej pak bezi zase vsechno v poradku. uz jsem i vymenil sitovku a porad to stejne. v logu nic neni. prosim pomozte.

[Marek Pasovsky]

Hmmm, a co na to BIOS - jak je tam nastaveny power management? Je tam nastaveno "disable"?

Marek

[hates]

tak tim to asi nebude. to by uspalo cely server a jakmile bych se prihlasil tak by to melo byt v poradku. smula je v tom ze ja se na server prihlasim a z venku porad tu komunikaci nelze navazat. i po restartu eth0 je to stejne. Sitova karta se probudi jakmile navazu spojeni ze serveru do internetu. pak je zase vsechno v poradku. prave proto mam pusteny ten ping at to navazuje neustale spojeni z vnitrku ven a nezatuhne komunikace. jeste nejaky napad co by to mohlo zpusobovat ????
