Server / Re: Jaký server pro webhosting?

« kdy: 10. 09. 2010, 10:36:29 »

Taky bych pridal svuj dotaz...
Predpokladejme nasledujici situaci:

~100 webu - firemni weby + administrace (10-100 pristupu/den na web)
Stolni PC: C2D ~2.5GHz, 4GB RAM, 500GB mirror HDD

Je mozne provozovat server doma? Rekneme s nejakym lepsim pripojenim - treba 20-40Mbps? V cem bude problem? Tipoval bych pomerne caste vypadky netu - a kdyz vypadne, znovuzprovozneni bude trvat hodiny. Nejaky dalsi problem?

Bezelo to sice v pasivu, ale po zmene se to nejak vyrazne nezlepsilo. Otevirani a ukladani souboru trva cca 5s, coz je dost, kdyz kazdou chvili aktualizujete obsah souboru.

Zrusil jsem docasne vsechny pravidla ve firewallu, vlozil modul do jadra pro podporu FTP prenosu a upravil firewall.

Kód: [Vybrat]

Gentoo ~ # lsmod | grep ftp
nf_conntrack_ftp        5972  0 
nf_conntrack           54717  7 xt_helper,nf_conntrack_ftp,nf_conntrack_ipv4,xt_state,xt_conntrack,xt_connmark,xt_CONNMARK

Gentoo ~ # iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -m helper --helper "ftp" -j ACCEPT

Soubor zde nelze vlozit, tak sem vlozim cely vypis. Prijde mi, ze je v nem zbytecne moc transakci (323)... (vstoupil jsem do slozky, otevrel/ulozil soubor a ukoncil spojeni).

K HDD...
Zkusil jsem wdidle3, bohuzel nepomohlo - kdyz jsem timer uplne vypnul, parkovaly hlavy snad jeste casteji. Nastavil jsem tedy max. hodnotu. Je to lepsi, ale stale to parkuje pomerne casto... Navic, kdyz povolim ACPI (128-253), stava se mi, ze mi tuhnou aplikace, ktere se zase obnovi za par sekund (zrejme v dobe, kdy jsou zaparkovane hlavy) - toto se mi drive nestavalo. Kdyz nastavim hdparm -B 254 ... tak mi zase obcas disk hreje, ackoli nic nedelam - kdyz jsem se dival na teplotu, mel 45°C, coz je dost a je to znat i na teplote krytu. Mam docela obavy, ze mi disk moc dlouho nevydrzi... (nedavno novy)

Distribuce / Puppy Linux pro bezneho uzivatele

« kdy: 14. 08. 2010, 10:15:50 »

Zdravim,

docela se mi libi Puppy Linux. Premyslel jsem, ze bych ho nainstaloval svemu otci, ktery sotva umi pracovat s Windows. Nicmene, Puppy ma veskere potrebne veci na plose a myslim si, ze by to nemel byt problem. Libi se mi, ze je cely v operacni pameti proto beha ukrutne rychle, coz je jeho nejvetsi plus.

Jaky je vas nazor pro nasazeni Puppy Linuxu pro Windowsackeho uzivatele, ktery ma minimalni znalosti?

* S powertop se mi podarilo snizit spotrebu az na 9W.

(Mereni probiha s minimalnim podsvicenim v klidovem stavu)

Kdyz povolim power management u HDD, objevi se znamy problem s parkovanim hlav, takze tento musim mit vypnuty a spotreba vzroste na tech cca 10-11W. Lze nejak resit tento problem s HDD jinak, nez uplnym vypnutim rizeni spotreby?

Nevite nekdo jak se dostat na stejnou spotrebu jako ma Windows? Konfigurace ve Windowsu i Ubuntu je standardni...
